In the fast-evolving world of digital assets, cryptocurrency transactions have become increasingly common — yet many participants still operate without formal agreements. Whether it’s lending USDT to a friend,委托 investing in volatile tokens, or purchasing digital assets through informal channels, the absence of a written contract can lead to serious legal complications. Despite regulatory uncertainties and the potential for contracts to be deemed invalid under Chinese law, having a well-drafted agreement remains a crucial tool for protecting your rights.
This article explores the real-world impact of cryptocurrency transaction contracts, drawing from actual court cases and legal precedents. We’ll examine how even an “invalid” contract can help clarify transaction intent, support litigation, and guide fair judicial outcomes.

Do Courts Consider Cryptocurrency Contracts?
Even in jurisdictions where cryptocurrency-related agreements may conflict with financial regulations, courts still review written contracts as key evidence.
Take the case (2024) Hu0117 Min Chu No. 5661, where Plaintiff Peng invested 1 million RMB in virtual currency based on Defendant Zhu’s high-return investment pitch. After suffering near-total losses five months later, both parties signed a written agreement in December 2021. The document explicitly stated that the 1 million RMB was a loan, outlining repayment methods (via property loan or direct refund), timeline, interest, contingency plans, and breach penalties.
Despite the underlying transaction involving prohibited crypto trading, the court recognized the post-hoc agreement as valid evidence of a civil lending relationship. Because the contract clearly defined obligations and remedies, the plaintiff’s claim was upheld — demonstrating that a well-structured contract can anchor legal protection even when the original activity is risky or non-compliant.
Contrast this with (2024) Lu03 Min Zhong No. 781, where Plaintiff Zhao sued Defendant Wang over a disputed crypto investment arrangement. With no written contract, the court had to rely solely on fragmented evidence —微信 chat logs, bank transfers, and voice recordings — to determine whether a委托 investment relationship existed.
Without clear terms, the court struggled to confirm mutual intent and ultimately questioned the validity of any agreement. This highlights a critical point: the lack of a formal document shifts the burden of proof onto circumstantial evidence, increasing litigation risk and uncertainty.

Even “Invalid” Contracts Reveal Transaction Truth
One major misconception is that if a cryptocurrency contract violates regulatory policies — such as those restricting crypto trading or financial innovation — it serves no purpose. But legality isn’t binary; even an invalid contract can serve vital evidentiary functions.
In (2023) Gan01 Min Zhong No. 8416, Plaintiff Ma sued based on bank transfer records, claiming a loan. Defendant Ma countered that the funds were for委托 investment in crypto. However, his only proof —微信 screenshots — failed to establish a clear委托 relationship. The court rejected the defense due to insufficient documentation.
This reflects a common scenario: one party assumes it's a loan (expecting repayment), while the other views it as investment (risk assumed by sender). These differing interpretations stem from unclear communication — easily preventable with a simple written agreement.
A recent case handled by legal practitioners involved a plaintiff who委托ed the defendant to buy crypto. The defendant argued there was no formal委托contract, only “friendly assistance.” The dispute dragged through first trial, appeal, and retrial — all hinging on defining the nature of the transaction.
Had both parties signed a contract specifying the relationship (e.g.,委托investment vs. gift vs. loan), much of this costly back-and-forth could have been avoided.
While many courts do invalidate crypto-related contracts citing violations of financial regulations or public order (as seen in (2024) Shen0115 Min Chu No. 45503), they often still recognize the underlying economic reality. For example:
- A借条 (IOU) may be legally unenforceable, but it proves the intent to borrow.
- Courts may acknowledge crypto’s property-like value, ordering返还of equivalent value in fiat currency if the asset cannot be returned.
- The transaction type — sale, loan, or委托investment — influences how losses are allocated.
Thus, even if a contract is voided, it helps judges reconstruct what actually happened, leading to more equitable rulings.
Clarifying Liability Through Contract Terms
Another critical function of contracts is defining responsibility — especially when things go wrong.
In (2023) Qian0103 Min Chu No. 769, the plaintiff transferred money to the defendant for purchasing virtual currency. The委托contract was ruled invalid. But the central issue became: who was at fault?
Because no written agreement existed:
- The plaintiff claimed ignorance despite working in blockchain education.
- The defendant argued he was merely helping out and made no profit.
- The court found both parties equally negligent: the plaintiff should have known the risks; the defendant gave advice and promised principal protection without proper disclosure.
Result? Each party bore 50% of the loss.
This outcome underscores a key principle: without contractual clarity, fault becomes subjective. A well-drafted contract should define:
- Whether the service is compensated or无偿
- Whether risk disclosures were made
- Whether the受托方 fulfilled duty of care
- Whether assets were kept separate
These factors directly influence how courts assess过错 and allocate losses.
Essential Clauses for Cryptocurrency Transaction Contracts
To maximize protection, every crypto-related agreement should include these core elements:
1. Accurate Identity Information
Include full names, ID numbers, contact details, and wallet addresses. This establishes authenticity and aids in criminal investigations if accounts are frozen.
2. Clear Transaction Description
Specify the nature of the deal:
- Is it a loan? Define amount, currency (preferably fiat), repayment method, interest rate, and deadline.
- Is it委托investment? State investment goals, risk tolerance, management fees, reporting frequency.
Use traceable payment methods (e.g., bank transfers) for accountability.
3. Risk Disclosure & Acknowledgment
Both parties should acknowledge awareness of market volatility, regulatory risks, and potential loss of principal.
4. Default and Remedies
Outline consequences of breach:
- Late repayment penalties
- Compensation for damages
- Dispute resolution mechanisms (mediation, arbitration)
5. Fallback Solutions
Plan for unforeseen events:
- What if the borrower can’t repay in crypto?
- Can repayment be made in RMB at a pre-agreed exchange rate?
- Is there a third-party guarantee?

Frequently Asked Questions (FAQ)
Q: If cryptocurrency contracts are often ruled invalid, why bother signing one?
A: Even if deemed invalid, contracts help prove transaction intent, define roles, and support claims for restitution or compensation.
Q: Can I use USDT or other stablecoins as repayment terms?
A: While possible, we recommend using法定 currency (like RMB) to avoid valuation disputes due to price fluctuations.
Q: Are verbal agreements enforceable in crypto disputes?
A: Rarely. Without written proof, courts struggle to verify terms. Always get agreements in writing.
Q: Should I include clauses about wallet security or private keys?
A: Yes — especially in委托investment scenarios. Specify who controls access and responsibility for loss due to hacks or mismanagement.
Q: Can a contract protect me from regulatory crackdowns?
A: Not fully. But it can demonstrate good faith, clarify civil liabilities, and assist in defending against criminal allegations.
Q: Is notarization necessary for crypto contracts?
A: Not required, but notarized documents carry stronger evidentiary weight in court.
Final Thoughts
Despite China’s strict stance on cryptocurrency transactions, a well-drafted contract remains one of the most effective tools for risk mitigation. It clarifies expectations, documents intent, supports legal claims, and guides fair outcomes — even when deemed unenforceable.
Whether you're lending digital assets,委托ing investments, or engaging in peer-to-peer trades, take the time to formalize your arrangements. In the high-stakes world of crypto, the difference between protection and exposure often lies in a single signed document.
