What does the unilateral closure of an account on a crypto exchange mean?

The unilateral closure of an account on a cryptocurrency exchange occurs when the platform decides to terminate its contractual relationship with the user without a prior request from the user. This is one of the most serious issues that can affect those who trade in cryptoassets, as it typically results in the immediate loss of access to the account, the suspension of transactions, and, in many cases, the temporary withholding of deposited funds.

Although exchanges typically reserve broad contractual powers to suspend or cancel accounts, these decisions are not exempt from the principles of good faith, proportionality, and transparency that govern contractual relationships. The fact that a platform includes a termination clause in its terms of use does not mean that it can apply it arbitrarily or without assuming certain obligations toward the user.

Our service is part of the claims against crypto exchanges and is designed to analyze the legality of the platform’s actions, the status of the withheld funds, and possible avenues for recovery.

Why do exchanges unilaterally close accounts?

The reasons exchanges typically cite vary. Among the most common are alleged violations of the terms of service, inconsistencies in identity verification processes, suspicions related to anti-money laundering policies, or internal risk management decisions.

Sometimes users receive a generic notice indicating an alleged violation of the terms of use, without specifying what specific conduct led to the action. In other cases, the account is closed almost immediately and without sufficient explanation.

Particularly common are cases related to AML or PBC holds, in which case the platform initiates internal review procedures that may result in permanent restrictions if it determines that regulatory or compliance risks exist.

The legal issue usually does not lie in the authority to close accounts, but rather in the manner in which that authority is exercised and the consequences it has for the owner of the assets.

Difference Between Permanent Account Closure and Temporary Account Suspension

It is important to distinguish between a locked account and a closed account.

When there is a temporary suspension, the platform leaves open the possibility of restoring access once certain internal verifications or reviews have been completed. The user remains a customer of the exchange, and the contractual relationship remains in effect.

In contrast, unilateral termination signifies the permanent end of that relationship. The platform decides to stop providing services to the user and typically limits any possibility of future reactivation.

In cases of temporary suspension, a strategy focused on unlocking an account on a crypto exchange, while in cases of permanent closures, the priority is usually to recover funds and obtain a satisfactory explanation for the decision made.

What rights do you have, and what obligations does the exchange have when it closes your account?

Obligation to Return Funds

Closing an account does not make the exchange the owner of the deposited assets. As a general rule, the platform remains obligated to facilitate the return of funds or allow for an orderly withdrawal within a reasonable timeframe.

Requirement to Provide a Rationale

When an account suspension is based on an alleged breach of contract, it is reasonable to require the platform to specify the specific basis for its decision. Generic references to internal policies or terms of service may not be sufficient for the user to properly understand and assess their situation.

Acting in accordance with the principle of good faith in contractual relations

Platforms must operate in accordance with minimum standards of proportionality, transparency, and good faith in contractual relations. A measure that is excessive, arbitrary, or maintained for a disproportionately long period may require a specific legal analysis.
