The field of crypto technology and mining equipment has, in recent years, moved from the fringes of the market into a segment involving substantial investments, high energy demands, and increasingly stringent regulation. In this article, we focus on the legal challenges faced by traders in crypto technology and mining equipment, the types of contracts and documentation they need, the regulatory, tax, and liability implications they must take into account, and how the attorneys of ARROWS advokátní kanceláře can assist them in this practice—both in the Czech Republic and in an international context. The article provides a clear overview of typical risks, real-life scenarios, and guidance on when it makes sense to involve the attorneys of ARROWS advokátní kanceláře.

Key specifics of doing business in crypto technology and mining equipment

Doing business in crypto technology and mining equipment has several fundamental specifics that distinguish it from standard electronics wholesale. It is typically a combination of hardware with extremely high demands on electricity, cooling and overall infrastructure. This hardware often has foreign origin and distribution, while the target clientele perceives any reduction in performance or unplanned downtime as a direct and immediate financial loss. These factors fundamentally affect how an entrepreneur in this segment should think about law, contracts and liability. From a legal perspective, this is not an isolated purchase agreement, but an entire chain of legal relationships from the manufacturer through the distributor to the end mining operator.

Crypto-technology traders typically do not sell only the “box” with an ASIC miner or a GPU rig. Very often, they add ancillary services to the sale, such as initial configuration, professional installation, remote management, recommendations for placement in a hosting centre, or direct brokerage of access to a specialised data centre. In practice, they therefore assume a complex combination of roles: hardware seller, systems integrator and sometimes even an intermediary for the mining service itself. Each of these roles entails different legal risks, a different scope of liability, and often different regulators or tax implications. It is precisely the mixing of these roles without clear contractual definition that is most often the source of legal disputes.

It is also important to consistently distinguish whether the trader operates purely in the B2B segment or combines wholesale with B2C sales. Many companies started as specialised e-shops focused on end users and gradually grew into wholesale and integration projects for major entrepreneurs or investment groups. However, as soon as an end consumer appears in the business relationship, strict consumer protection law comes into play, including specific information duties, statutory rights to withdraw from the contract and other special rules, non-compliance with which may lead to severe sanctions by supervisory authorities or to the absolute invalidity of certain contractual provisions.

Recently, environmental and energy aspects have increasingly come into play as well. Mining equipment has enormous energy consumption and generates a significant amount of waste heat. In modern projects, it is therefore no longer just about the simple sale of hardware, but about complex energy solutions where mining technology is integrated into a broader system of heat utilisation, industrial operations or advanced data centres. Such projects already directly affect energy law and construction law under Czech legislation and require public-law licences and permits in the Czech Republic. If a trader underestimates these connections, they may face the project being blocked by authorities or unexpected requirements for additional permits.

A further characteristic of this industry is significant market volatility and rapid technological development. The value of mining equipment strongly depends on the current mining difficulty, the price of electricity, cryptocurrency exchange rates and the availability of a new generation of more efficient chips. This has a major impact on how delivery times, sale price fixation, pre-orders and advance payments for future deliveries are set. In times of sharp market fluctuations, it is very easy to end up in a situation where one party is strongly motivated to step away from the contract or unilaterally amend it to its advantage. The legal framework for these situations—especially the possibilities for contract changes, termination, withdrawal or damages—must be very carefully thought through already at the contract drafting stage.

Crypto-technology traders should therefore understand law not as an administrative brake, but as a strategic tool for effective risk management. From the perspective of the lawyers at ARROWS advokátní kancelář, the ideal approach is for legal support to be involved directly in designing the business model and processes, rather than only at the moment an open dispute has arisen or the company is facing an inspection. This makes it possible to address sensitive issues in time, such as regulatory classification, licensing, AML obligations or export restrictions to high-risk countries.

Typical roles and business models in practice

In practice, we encounter several typical models among crypto-technology traders. Some companies operate as pure wholesalers or distributors, purchasing equipment directly from foreign manufacturers or master distributors and reselling it to smaller resellers or end entrepreneurs. In such a model, it is crucial to properly address supply contracts, liability for defects and the legal relationship with the manufacturer—especially with regard to international claims and service cycles.

Another group consists of specialised e-shops and sellers focused on small and mid-sized investors. Although this is often formally a B2B sale, in reality they may in many cases serve natural persons who are not entrepreneurs or entities whose business status is not fully transparent. If a seller presents itself as a partner for “investors”, it may unknowingly enter a grey zone where it influences the client’s investment decision-making or provides specific recommendations. This can have serious consequences both in terms of liability for damages and potentially from the perspective of strict financial services regulation.

Integrators and operators of mining hosting centres also play a significant role. They combine the sale or lease of equipment with its subsequent physical placement in a data centre or in industrial sites with access to cheaper energy. From a legal perspective, this is no longer merely the sale of a thing, but a complex contractual relationship that includes elements of lease, services, SLAs, security arrangements, liability for outages and sometimes even revenue sharing from mining. Here, precise contractual documentation is absolutely key, clearly and uncompromisingly allocating operational and financial risks between the hosting operator, equipment owners and other partners.

A specific category consists of companies that combine hardware trading with services for managing an entire portfolio of mining equipment or participation in broader investment structures. In such a case, they may come into conflict with legal requirements relating to collective investment, the provision of investment services or the management of third-party assets. Even if these companies outwardly label themselves as “technology” businesses, the substantive content of their services is always decisive for the regulator. The lawyers at ARROWS advokátní kancelář therefore recommend first analysing the actual business model in detail and only then choosing the appropriate contractual and corporate setup.

Last but not least, it is worth mentioning the role of service partners and buyback companies that provide repairs, refurbishment, and the secondary market for mining equipment. The secondary market is often overlooked, even though it raises complex issues of liability for defects in used goods, information duties regarding the actual technical condition, and the risk that the equipment originates from an illegal or otherwise problematic source. Verifying the origin of the equipment and carrying out so-called due diligence of both suppliers and buyers becomes a practical necessity here.

Legal qualification: hardware vs. a crypto-asset-related service

A key legal issue is determining precisely where the line lies between a mere sale of hardware and a situation where the trader’s activity becomes subject to crypto-asset or financial services regulation. In the usual case where a company sells mining equipment without any follow-on value-added service, this is a standard commercial relationship governed by the Czech Civil Code. A serious problem arises, however, when the trader begins offering comprehensive service packages that combine hardware, configuration, access to a pool, and operation in a data centre in exchange for a share of the mined cryptocurrency.

In such hybrid models, it is necessary to analyse very carefully whether the trader is in fact providing a service that could be regulated as a crypto-asset-related service, an investment service, or another financial service under EU or Czech regulation. The legal interpretation may not always be clear-cut and often depends on the specific contractual setup, marketing communications, and actual implementation. Underestimating this issue may lead to intervention by supervisory authorities, an obligation to cease operations immediately, or significant penalties for unauthorised business activity in a regulated segment.

Another sensitive boundary is whether the trader assumes responsibility for future investment returns. If the contracts or marketing state that the purchase of the equipment will ensure a certain profit or promise a specific payback period, this may later be legally construed as assuming a guarantee or providing investment advice. If mining profitability declines or technical problems occur, clients may then assert claims for damages, arguing that they relied on the trader’s professional guarantee.

The attorneys at ARROWS, a Prague-based law firm, therefore work with clients in practice to fine-tune the wording of marketing materials, contracts, and terms and conditions in detail so that they are clear, while at the same time not crossing the line that could trigger unintended regulation or unlimited liability.

In light of EU crypto-asset regulation, in particular the MiCA Regulation, it is increasingly important to distinguish when a trader is already stepping into the role of a provider of crypto-asset-related services and when they remain purely a technology supplier. Although MiCA is aimed primarily at crypto-asset-related services and the crypto-assets themselves, subsequent interpretative practice may also affect certain hybrid models involving mining hardware. For larger groups, international players, and traders operating in multiple Member States, it is therefore essential to have an expert legal opinion prepared that safely delineates this boundary.

Contractual documentation and business relationships in the crypto-technology sector

Contractual documentation is a crucial tool for crypto-technology traders to manage risk effectively. A standard purchase agreement simply is not sufficient if, alongside the delivery of hardware, installation, configuration, remote administration, or hosting is also agreed. In practice, framework agreements are therefore commonly used to govern long-term cooperation, with subsequent deliveries carried out through individual orders or handover protocols. Such a setup is flexible, but it requires absolutely precise contractual mechanics to avoid uncertainty about what exactly has been agreed.

For traders operating in an international environment, it is essential to clearly agree on the choice of governing law, court jurisdiction or an arbitration clause, taking into account their specific position in the supply chain. From the perspective of a Czech trader, it may be tempting to accept a foreign supplier’s contract as-is, typically under the law of the manufacturer’s country. In the event of a dispute, however, this may mean extremely complex and costly proceedings in a foreign language and under foreign law. The attorneys at ARROWS, a Prague-based law firm, therefore help clients negotiate a reasonable compromise, such as the application of Czech law or other neutral law and a reputable arbitral institution.

Another important element of contractual documentation is the general terms and conditions. In this industry, they are usually more extensive because they must cover a range of technical and operational aspects. They typically regulate the exact parameters of the equipment, the method of acceptance, testing, complaints, limitations of liability, and also the method of communication and documentation, such as operational reporting or access to monitoring systems. A common mistake is that terms and conditions are blindly copied from another segment or have been created through incremental additions without systematic legal review, which can lead to the invalidity of key provisions.

Provisions on liability for damages and contractual penalties are particularly sensitive. In cryptocurrency mining, every day of downtime can mean a real and substantial financial loss. If the trader provides not only hardware but also hosting or management services, clients often demand strict contractual penalties for failure to meet availability or performance. It is therefore necessary to define very precisely how availability is measured, which outages count, and what legitimate exclusions apply, such as outages on the energy supplier’s side, third-party attacks, or planned technical shutdowns. Without this precision, there is a risk that the trader will come under fire from financial claims for events they could not realistically influence.

Performance parameters, warranties, and SLAs

One of the most common subjects of disputes in this sector is equipment performance parameters and the warranties relating to them. Clients typically expect the declared hashrate to be consistently achieved under normal operating conditions and energy consumption to correspond precisely to the manufacturer’s product specifications. In practice, however, these values depend heavily on external factors such as power quality, ambient temperature, dust levels, or the stability of the internet connection. It is therefore necessary to define clearly in the contracts under what conditions the stated parameters are guaranteed, how they are measured, and what deviations are acceptable.

Warranty arrangements should strictly distinguish statutory liability for defects from any contractual enhancements. We often see traders using attractive marketing labels such as “extended warranty”, but the contract does not clearly define what this specifically means. In the mining equipment segment, there can be a huge difference between a warranty for basic functionality of the equipment and a warranty for its nominal performance. If a performance warranty is not explicitly and in detail regulated, a court will not automatically assume it in the event of a dispute.

For hosting and equipment management, SLAs (Service Level Agreements) are increasingly used, clearly setting out the level of service provided, typically expressed as a percentage of availability. For an SLA to be legally enforceable and at the same time realistic for the operator, the measurement rules, reporting, incident notifications, and remediation method must be regulated in detail. For example, it may be agreed that for a certain level of unavailability the client is entitled to a discount on the service fee, but not automatically to compensation for all lost mining output. The attorneys at ARROWS, a Prague-based law firm, help clients set SLAs so that they are commercially attractive while also reflecting real operational capabilities.

An interesting feature is also so-called best effort clauses, where the provider undertakes to use its maximum efforts to achieve a certain level of performance or availability. Such clauses may appear flexible on the surface, but without clear metrics they are, in practice, very difficult to enforce. In the crypto-mining environment, where performance is assessed precisely, it is more appropriate to work with specific parameters and compensation models. At the same time, it is essential to incorporate into contracts a workable mechanism for changing parameters over time, for example during firmware upgrades or due to objective changes in operating conditions.

Most common questions on contractual relationships and documentation

The first question clients often ask is whether a standard purchase agreement or terms and conditions freely downloaded from the internet are sufficient for their business. In the crypto-technology segment, this is almost never sufficient, because standard universal templates do not address specific performance parameters, the high value of the equipment, or operational risks associated with energy and security. The lawyers at ARROWS advokátní kanceláře therefore recommend working exclusively with industry-tailored documentation that accurately reflects the client’s specific business model.

The second typical question concerns how strongly the merchant should be protected in contracts and whether it makes sense to use broad, one-sided exclusions of liability. Practice clearly shows that one-sided contracts may protect the merchant in the short term, but in the long term they damage relationships with business partners and, paradoxically, increase the risk of disputes escalating. A reasonable compromise is to clearly define risks that the merchant cannot objectively influence—such as changes in mining difficulty or cryptocurrency market prices—and exclude them entirely from contractual liability, while acknowledging liability for genuinely controllable factors and setting reasonable financial caps.

The third frequent question is whether it makes sense to address an arbitration clause or the choice of foreign law. For larger international contracts, arbitration can be a major advantage because it is significantly faster and more confidential than traditional court litigation, but it also involves higher upfront costs. The choice of law should always logically follow from where the merchant’s main activities are located and where an arbitral award or court judgment can be effectively enforced. The lawyers at ARROWS advokátní kanceláře help clients assess when it is appropriate to insist on Czech law and when it is, conversely, reasonable to accept a foreign legal framework supplemented by an internationally reputable arbitral institution.

Regulatory and compliance aspects (AML, sanctions, product safety)

In addition to purely contractual risks, traders in crypto technology and mining equipment also face growing regulatory requirements. Particular attention must be paid to AML/KYC, international sanctions regimes, export restrictions, and product safety, including mandatory CE marking and related European directives. Even a business that subjectively sees itself as merely a hardware seller can very quickly find itself in the position of an obliged entity or a sanctions violator if it underestimates these areas.

AML and screening of business partners

In the AML area, it is absolutely crucial whether the merchant enters into relationships that may be considered higher-risk financial transactions and whether, within its model, it does not, for example, hold or transfer its clients’ crypto-assets. If, in addition to selling equipment, the merchant also managed the mining proceeds themselves, collected them into its own accounts and then forwarded them to clients, it would fall under the regime of an obliged entity with a strict duty to perform customer identification and monitor unusual transactions. Although most pure hardware traders do not fall under the AML regime, hybrid models require careful assessment.

In the practice of crypto-technology traders, there is an increasingly frequent requirement to screen business partners even in cases where this is not a mandatory AML procedure under Czech legislation. This is more about reputational and commercial due diligence. If a merchant supplies larger volumes of mining hardware to entities whose funds or source of capital may be challenged in the future, it faces not only the risk of non-payment but also serious reputational damage or complications during bank reviews.

From an AML perspective, it is also important to distinguish whether the merchant accepts payments in cryptocurrencies and how it handles them further. Accepting payment in a crypto-asset in itself does not yet mean that the merchant is an obliged entity, but in combination with other activities it may be a clear signal to tighten internal processes. Repeated high-volume transactions with poorly identified entities from high-risk jurisdictions may attract the attention of banks, which may delay transactions or block accounts entirely. The lawyers at ARROWS advokátní kanceláře help clients set up internal procedures for partner screening, both in the form of internal policies and practical checklists for the sales department.

Sanctions, export restrictions and geographic risks

Sanctions regimes and export restrictions are becoming an increasingly important topic. Mining equipment, especially modern and extremely powerful ASIC miners, has technical parameters approaching high-performance computing technologies, which sanctions authorities closely scrutinise in relation to certain states and entities. Merchants must therefore carefully monitor to whom they sell goods, in which specific jurisdiction the equipment will actually be operated, and whether the transaction violates international sanctions or export regulations relating to technologies that may be considered dual-use goods. Even if most standard miners may not fall into this category, for high-end equipment or custom solutions a preliminary legal analysis is essential.

A merchant should have basic internal mechanisms implemented to reliably determine whether its customer is on an international sanctions list and whether the destination country is subject to special restrictions. Failure to comply with sanctions regulations may lead to serious financial penalties, seizure of goods, blocking of payments and, in extreme cases, devastating criminal-law consequences.

A very practical aspect of the sanctions and export regime is communication with banks and payment institutions. If a merchant enters into contracts with partners from jurisdictions that are sensitive for banks, payments may be blocked or significantly delayed, even where there is formally no breach of sanctions. The lawyers at ARROWS advokátní kanceláře help clients in such situations not only with assessing the risk itself, but also with preparing supporting documents for banks and communicating with them so that transactions can be carried out without unnecessary delays.

Product safety, CE and liability for defective products

Electrical and electronic equipment must meet strict safety requirements when placed on the EU market. For mining hardware, this most commonly involves requirements for electrical safety, electromagnetic compatibility, and protection against overheating and fire. The manufacturer, or the party that places the equipment on the EU market under its own name, must ensure an official conformity assessment, maintain the required technical documentation, and affix the CE marking to the product.

If a trader imports equipment from third countries and sells it under its own brand, or in a situation where it effectively assumes the role of an EU importer, it bears full responsibility for ensuring that the equipment meets all of these EU requirements. In the event of damage caused by a defective product, it may be held liable under specific product liability regulations. This may include compensation for enormous property damage and personal injury, for example if defective equipment were to cause a fire in a data centre.

The attorneys at ARROWS therefore recommend that clients do not rely blindly on statements made by a foreign manufacturer, but actively verify whether the documentation is complete and whether the equipment actually corresponds to the declared parameters. For larger projects, it is worth considering an independent technical audit. From a legal perspective, it is then crucial to properly set out recourse mechanisms in purchase and supply agreements so that, in the event of damage, the trader can assert claims against its original supplier or manufacturer.

Frequently asked questions: Regulation and compliance

1. Does a trader in mining hardware have to register as a crypto-asset service provider?
One of the frequently asked questions is whether a trader in mining hardware must register as a crypto-asset service provider. The answer always depends on the specific business model. If it only sells hardware without any handling of clients’ crypto-assets, it does not fall under this regime. However, once it starts providing wallet management, pooled mining, or custody of mined assets, a registration or licensing obligation arises.

2. How extensive should the screening of business partners be, especially those from abroad?
Another common question is how in-depth the screening of business partners should be, especially for foreign entities. In practice, this is based on a logical combination of the overall transaction value, the risk level of the relevant jurisdiction, and the type of partner. In some cases, a basic check against sanctions lists and identity verification is sufficient; for major contracts, more detailed due diligence is advisable.

3. How should rules for screening business partners be set?
When setting the scope of screening, it is important to take into account the company’s risk profile and the individual business relationships. The attorneys at ARROWS help set internal rules based on a combination of transaction value, jurisdiction risk, and the nature of the business partner.

Tax, customs and accounting aspects of trading in mining equipment

The tax and customs aspects of trading in crypto equipment are often underestimated, yet they can fundamentally affect the economics of the entire project. This area brings together issues of value added tax, corporate income tax, customs regulations, and sometimes transfer pricing within holding groups. Incorrect setup may result in additional tax assessments, high penalties, late-payment interest, or shipments being blocked directly at customs.

VAT and cross-border hardware supplies

In the area of VAT, it is crucial to distinguish precisely whether the transaction involves a domestic supply of goods, an intra-Community supply within the EU, an import from a third country, or, conversely, an export outside the EU. Each of these regimes has different rules for applying VAT, exemptions, and reporting. A trader that purchases hardware abroad and then sells it to clients in various Member States must carefully monitor where its VAT registration obligation arises and whether so-called chain transactions occur, in which it is necessary to correctly determine which link in the supply chain is associated with the transport.

Cross-border supplies of mining hardware within the EU typically fall under the intra-Community supply of goods regime, provided the conditions for the supplier’s VAT exemption and the shift of the tax liability to the customer are met. It is essential that the supplier has conclusive evidence that the goods were actually transported to another Member State, which can sometimes be complicated in an environment of fast deliveries and logistics partners.

When importing from third countries, it is important to correctly set the customs value on the basis of which VAT and any customs duty are calculated. If the value of the equipment also includes additional related services, such as configuration or installation, it is necessary to assess whether these form part of the customs value or constitute a separately taxable service. The attorneys and tax advisers at ARROWS help clients set up the contractual and invoicing model so that it complies with tax regulations and minimises the risk of disputes with the tax authorities.

Income tax, depreciation and group structure

A significant role is also played by correctly determining the customs tariff classification of mining equipment. Customs duty rates differ depending on whether the equipment is classified as general computer hardware, specialised computing equipment, or other electronics. Incorrect classification may lead to additional customs duty being assessed during a subsequent customs audit. From an income tax perspective, it is also important to address how purchases and sales of hardware are reflected in the accounts. Mining equipment is often expensive and has a very limited economic life, which raises the question of whether to record it as inventory or as fixed assets, which depreciation regime to choose, and how to set policies for its disposal or sale on the secondary market.

For capital-intensive projects, financing is often arranged through leasing, loans, or intra-group lending. This is where the complex issue of transfer pricing comes into play, especially if foreign entities within the same group are involved in the project. Tax authorities may examine whether prices for hardware, financing, or services provided are set artificially in order to shift profits to other jurisdictions. Well-prepared transfer pricing documentation is an important part of tax compliance in this segment.

Liability, disputes and crisis situations

Trading in crypto equipment and mining hardware has a high potential for legal disputes, as it combines the high financial value of the equipment, technological complexity, and extreme time sensitivity. Any delay in delivery, defective batch, or unexpected outage can cause clients significant financial losses. It is therefore absolutely crucial to have a well-thought-out strategy in advance for managing liability, handling complaints, and addressing potential disputes.

The basic cornerstone is clear contractual regulation of liability for defects and compensation for damage. In B2B relationships, many aspects can be agreed contractually, including a reasonable cap on total damages or the complete exclusion of lost profits. However, liability cannot be excluded entirely, especially where this would conflict with mandatory statutory provisions. In practice, a proven combination of financial liability limits, specific exclusions, and contractual mechanisms for handling complaints is therefore used.

Another key element is a dispute escalation mechanism. It is highly advisable for contracts to provide that the parties will first attempt to resolve any disagreements through amicable negotiations at management level, or, where appropriate, through formal mediation, before filing a lawsuit with a court or commencing arbitration. In international relationships, this can drastically reduce costs and shorten the time during which a project is blocked. The attorneys of ARROWS, a Prague-based law firm, represent clients in these negotiations, prepare settlement proposals, and build effective negotiation strategies.

International elements and cross-border transactions

Trade in crypto-technology and mining equipment is inherently international. Equipment manufacturers are most often based outside the European Union, customers are spread across the globe, and supply chains include logistics hubs in various countries. This brings a vast number of complex legal issues, from the choice of governing law and court jurisdiction, through cross-border recognition of decisions, to differing local requirements for product safety, taxes, or licensing.

Mining-centre infrastructure often relocates to where energy is cheapest, which means that hardware purchased in one country may be operated on the other side of the world. In international transactions, it is therefore absolutely crucial to carefully choose contractual arrangements on governing law and dispute resolution. If a Czech trader enters into a contract with a manufacturer outside the EU, they must take into account that, in the event of a dispute, it may be extremely difficult to enforce their rights in a foreign jurisdiction. For this reason, international trade often prefers agreeing an arbitration clause with a reputable international arbitral institution.

Another fundamental topic is the coordination of tax and customs aspects between different states. The same transaction may have diametrically different tax consequences in different jurisdictions, not only from the perspective of VAT, but also corporate income taxes. If multiple companies within a single holding group are involved in the business model, it is necessary to consider transfer pricing and to proactively prepare robust documentation that will withstand a potential tax audit in any of the affected countries without issue.

The role of ARROWS International in cross-border matters

ARROWS, a Prague-based law firm, is a proud member of the international ARROWS International network, which brings together experienced legal and tax specialists in a number of key jurisdictions around the world. For clients in the crypto-technology sector, this means they can handle their case or international project in a fully coordinated manner across multiple countries at the same time, without having to search for local law firms abroad in a complex and independent way.

In practice, this works so that the client conveniently communicates with their main contact at ARROWS, a Prague-based law firm in the Czech Republic, who fully coordinates the work of foreign colleagues. They provide precise local legal insight, for example on product safety issues, specific permits, customs regimes, or local taxes in the given country. The result is a coherent, secure, and comprehensive solution that takes into account differences between individual legal systems and minimises the risk that a project will be legal in one country but highly problematic in another.

Setting up internal processes, compliance, and governance

In addition to contracts, taxes, and external regulation, a critical element of successful business in the crypto-technology sector is the proper setup of internal processes within the company itself. This includes not only compliance in the narrow sense, but also comprehensive operational risk management, drafting internal policies, regular employee training, precise contract records, and reporting. Without these elements, even the best-drafted contracts and legal opinions may be entirely ineffective in day-to-day practice.

A crypto-technology trader should have clearly defined roles and responsibilities in the areas of contract approvals, partner screening, handling complaints, and customer communications. Larger companies set clear internal financial limits regarding who specifically may sign contracts of a certain value, which types of contracts must mandatorily undergo legal review, and what documentation must be fully collected before the contract is concluded. The attorneys of ARROWS, a Prague-based law firm, help clients design this governance framework so that it precisely matches the size, structure, and nature of the business.

An important part of internal processes is also the protection of personal data and sensitive technical data. Operators of hosting, equipment management, or online platforms collect enormous amounts of data about their clients, their devices, actual performance, and sometimes even their blockchain addresses. This information has huge commercial value and is also subject to strict personal data protection (GDPR) and cybersecurity regulation. It is therefore essential to ensure not only technical security, but also watertight legal protection of this data, including detailed contractual arrangements with processors and external IT service providers.

Final summary

Doing business in crypto-technology and mining equipment is financially attractive, but legally, tax-wise, and commercially exceptionally complex. Traders in this segment today face a demanding combination of the classic risks of wholesale electronics and specific risks associated with crypto-assets, energy law, international sanctions regimes, and very rapidly changing legislation. Seemingly simple operational decisions—such as choosing a foreign supplier, setting the amount of deposits, or wording marketing promises—can in practice have fundamental impacts on overall liability, taxation, or even the very legality of the entire business.

For business owners, top management and investors, it is therefore crucial to view specialised legal services for crypto-technology traders as a strategic tool for business growth and protection, rather than merely an operating cost. Well-structured contracts, well-thought-out compliance, perfectly handled tax and customs matters, and preparedness for crisis disputes can demonstrably reduce the risk of enormous financial losses, transaction blocks, high fines, reputational damage and unplanned project delays.

The attorneys at ARROWS, a Prague-based law firm, have been focusing on this specific area for a long time and assist clients both with individual partial matters—such as contract review, handling a complaint, or a tax assessment of a transaction—and with the comprehensive set-up of an entire business model from scratch. Thanks to high professional liability insurance with a limit of up to CZK 400,000,000 and the extensive international network of ARROWS International, they are able to reliably support even large holding groups and ambitious projects with an international reach.

If you do not want to take unnecessary risks of costly mistakes, damages, delays or ruinous fines in such a dynamic and sensitive sector as trading in crypto-technology and mining equipment, it makes sense to involve experts as early as possible. Contact the attorneys at ARROWS, a Prague-based law firm, by email at office@arws.cz and discuss your specific plans, risks and opportunities with them. Timely legal support will ultimately save you far higher costs than the price of obtaining it.

Most common questions about legal services for crypto-technology and mining equipment traders

1. How do I know whether basic contracts and terms and conditions are sufficient, or whether I need a comprehensive legal solution?

In most cases, there is a direct correlation: the higher the overall financial value of your contracts, the more international elements are involved in your business, and the more intensively you combine the sale of the hardware itself with additional related services such as hosting, administration or revenue sharing, the more sense a comprehensive tailored legal solution makes. Basic contracts and general terms and conditions may be sufficient for smaller, local and fully standardised transactions, but once you embark on larger projects or long-term relationships with key partners, individual contract structuring becomes essential. 

2. When, as a trader in mining hardware, do I fall under the regulation of crypto-assets or financial services?

You typically enter this regulated regime when your activity goes beyond the mere sale of hardware and you begin, in any way, to handle your clients’ crypto-assets. These are situations where you manage their mined proceeds, hold their private keys or funds in your wallets, or actively offer them comprehensive investment packages firmly linked to mining. The mere pure sale of hardware does not trigger financial services regulation, but hybrid models are examined very closely from the regulator’s perspective.

3. What should I do if I have a dispute with a foreign supplier or customer and they refuse to communicate?

The first and absolutely crucial step is a detailed legal analysis of the existing contract, on the basis of which it is determined which governing law applies to the relationship and how the resolution of any disputes has been agreed. Based on these findings, a qualified pre-action notice can be prepared in the relevant language, or an official proposal for out-of-court negotiations or mediation. If the other party still does not respond, it is appropriate, without undue delay, to consider initiating court or arbitration proceedings in accordance with the contractual arrangement. 

4. What are the main tax and customs risks that I, as a crypto-technology trader, should not underestimate?

Among the most common and most dangerous mistakes are incorrect VAT set-up for complex cross-border transactions, incorrect customs tariff classification of imported equipment, underestimating the strict evidentiary requirements for intra-Community supplies within the EU, or unclear allocation of equipment between inventory and fixed assets. In more complex group structures, there is also a huge risk associated with incorrectly set transfer pricing between related entities. Unfortunately, these mistakes very often only become apparent after a long time during a tax or customs audit, when there may be a massive additional assessment of tax, penalties and interest. 

5. To what extent do I need to deal with AML and client due diligence if I “only” sell hardware?

If you demonstrably sell exclusively the hardware itself and do not handle your clients’ crypto-assets in any way, nor provide financial settlement for them, you will not normally be considered an obliged entity under AML regulations. Nevertheless, it is highly advisable, as part of risk management, to implement basic partner due diligence processes—especially for high-value transactions and for foreign entities from high-risk jurisdictions. This is not only about the strict wording of the law, but about protecting your reputation and maintaining key relationships with banks, which may proactively block unverified transactions or terminate cooperation with you because of them.
