Compliance rules live in dedicated policy contracts, separate from the vault's core logic, so they can be added, changed, or removed without redeploying the vault. ### What can be gated Compliance checks can be applied to the following vault actions: * **Deposits** — both synchronous deposits and request-based deposits * **Redemption requests** * **Share minting and burning** * **Share transfers** — any transfer of vault shares between wallets Checks are configured per action, and a vault may use none, some, or all of them. ### How it behaves When a gated action is performed, the vault passes the details of the action (such as the depositor wallet and the amounts involved) to the policy engine, which evaluates them against the configured policies in order. {% hint style="warning" %} If any policy rejects the action, the entire transaction reverts. The deposit, redemption, mint, burn, or transfer does not take place, and no assets or shares move. {% endhint %} ### Example policies Policies can, for example: * require that a wallet holds a verified identity credential (such as KYC or AML status), using Chainlink ACE's cross-chain identity framework * screen wallets against allowlists and denylists (e.g. sanctioned addresses) * restrict an action to wallets holding a specific role, such as verified or accredited investors * enforce volume or rate limits * pause a given action entirely, or restrict it to certain time intervals The exact set of rules is defined per vault, so the checks a depositor encounters depend on how that vault is configured. ### Configuration Only the vault owner or its admins can enable, replace, or disable compliance checks on a vault. The policy rules themselves are managed on the Chainlink policy engine. Chainlink ACE is one of the validation mechanisms available to Enzyme Vaults — share transfers, for example, can alternatively be restricted using address lists. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.enzyme.finance/onyx-user-documentation/enzyme-vault/compliance.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
