Cryptocurrency Disputes: Contractual Conflicts
In the digital era where cryptocurrencies are transforming financial transactions, contractual disputes involving these digital assets are multiplying in Switzerland. PBM Avocats observes a significant increase in litigation between investors, trading platforms and blockchain project developers. These disputes, often complex, raise novel legal questions at the intersection of contract law, technology and finance.
Main Sources of Contractual Disputes and Legal Bases
| Type of Contract / Dispute | Main Legal Basis | Typical Remedies | Applicable Law |

| Exchange general terms (account freeze, fees, withdrawal refusal) | Art. 97 CO; art. 2 SCC (good faith) | Notice to perform, interim measures, contractual action | Swiss law (if activity directed towards CH) |
| Defective smart contract (DeFi, DAO, protocol) | Art. 97 CO; art. 41 CO (tort liability) | Damages action against developers | PILA — connection to developers' domicile |
| ICO / STO: non-performance of white paper | Arts. 97-109 CO; arts. 28-31 CO (fraud/mistake); FinSA | Contract rescission, damages, criminal complaint | Issuer's seat + FinSA connections |
| Institutional custody contract | Arts. 472 et seq. CO (deposit); CISA; FinSA | Contractual action, FINMA report | Swiss law (CH establishment) |
| Mining / pooled staking contract | Arts. 530 et seq. CO (simple partnership); art. 305 CO | Dissolution action, asset distribution | Swiss law if simple partnership domiciled in CH |

Types of Cryptocurrency Contracts under Swiss Law
In Switzerland, several types of contracts govern cryptocurrency transactions:
- Exchange contracts between cryptocurrencies and fiat currencies
- Smart contracts with self-executing clauses
- Custody contracts (safekeeping of digital assets)
- Investment contracts in blockchain projects (ICO, STO)
- Mining and staking contracts
The DLT Act of 2021 introduced the concept of registered uncertificated securities (arts. 973d et seq. CO), allowing legally secure tokenisation of assets. This legislative innovation provides increased legal certainty for contracts involving cryptocurrencies.
Disputes Related to Trading Platforms
Relations between users and trading platforms generate significant litigation. The main friction points concern:
- Unexpected account freezes during KYC/AML procedures
- Asset losses following security breaches
- Delays or refusals to withdraw funds
- Disputes over fees applied to transactions
- Service unavailability during periods of high volatility
Our team systematically examines the validity of general terms clauses under Swiss law on obligations and consumer protection (PILA art. 120 for consumers domiciled in Switzerland).
Smart Contracts and Swiss Law
Smart contracts present a particular challenge for traditional contract law. Swiss case law is beginning to recognise their validity subject to the essential conditions of contract formation: free consent, specific subject matter and lawful cause. The interpretation of computer code as an expression of the parties' intent is a legal innovation that our lawyers follow closely.
Evidentiary and Jurisdictional Challenges
Contractual disputes involving cryptocurrencies present unique challenges. Our lawyers use various techniques to establish evidentiary elements:
- Forensic analysis of blockchain transactions
- Notarial certification of digital wallet addresses
- Technical expert assessment of smart contract code
- Documentation of interactions with trading platforms
Determining the competent court and applicable law relies on the PILA and contractual clauses. Switzerland, with its favourable legal infrastructure, constitutes an attractive forum for resolving such disputes.
Frequently Asked Questions about Cryptocurrency Contractual Disputes in Switzerland
Are the general terms and conditions of a foreign exchange enforceable against a Swiss consumer?
Not necessarily. The PILA (art. 120) protects consumers domiciled in Switzerland: the law of their country of residence applies if the service provider directed its activity towards Switzerland. Forum selection clauses in general terms may be invalidated for consumers. PBM Avocats systematically analyses the validity of such clauses before adopting a strategy.
Can a smart contract constitute a valid contract under Swiss law?
Yes. The Code of Obligations does not prescribe any particular form for most contracts. A smart contract representing an agreement of wills on a specific and lawful subject matter is in principle valid. The DLT Act of 2021 strengthened legal certainty by recognising registered uncertificated securities (arts. 973d et seq. CO). In the event of a dispute, the interpretation of computer code as an expression of the parties' intent is the main challenge.
What remedies are available if an ICO project failed to deliver what was promised in the white paper?
Depending on the circumstances: (1) contractual action for non-performance (art. 97 CO) if the white paper constitutes a contractual offer, (2) action for fraud or essential mistake (arts. 28-31 CO) if misleading information determined the investment, (3) criminal complaint for fraud (art. 146 SCC) if sophisticated deception is demonstrated. The classification of the token (securities or not) also determines the applicable FinSA protections.
How is damages calculated for a blocked crypto asset during a market rise?
The loss includes the value of the assets at the time of restitution less the value at the time of blocking, documented lost investment opportunities, and costs incurred in asserting one's rights (legal fees). The high volatility of crypto assets makes this calculation complex — Swiss courts generally use the value at the date of the judgment or resolution, less the value at the time of blocking (arts. 99-100 CO).
