Crypto business partner disputes: shares, keys and wallets

Why crypto projects break more painfully than others

In a conventional business the assets are recorded against the company: there is a register, an account, a signature. In crypto, control equals ownership — whoever holds the private key disposes of the assets. If the wallet sits with one partner, the others formally have no connection to the assets at all, however much money they put in or how many years they worked.

What counts as evidence

• Correspondence — messengers, email, task trackers: the arrangements on shares, distribution and roles.
• On-chain history — who contributed funds and when, and how assets moved between participants' wallets.
• Bank transfers and documents evidencing how the project was funded.
• Public traces: the website, investor decks, repositories where team roles are recorded.

Verbal arrangements are not hopeless: courts examine how the parties actually behaved. But the cost of the dispute is several times higher without documents.

What to do when conflict breaks out

1. Record the position immediately. Screenshots of balances, wallet addresses, and an export of the correspondence with metadata — before chats are deleted and assets moved.
2. Assess the risk of dissipation. If your opponent has control, you are counting in days: interim relief and notices to the platforms the assets might reach only work while the funds are still traceable — the mechanics are the same as in stolen asset cases.
3. Negotiate, and document it. Most such disputes end in a negotiated split — what matters is that the agreement is technically enforceable, not just legally sound.
4. Court or arbitration, according to the jurisdiction fixed by the project's structure; where there is no structure, jurisdiction itself becomes part of the dispute.

Prevention

Multisig with keys distributed between partners, a written agreement on shares and exit terms, and a separate project wallet: three measures that remove nine out of ten future conflicts.
