# AML To keep Nest secure and globally compliant, Nest has implemented a sub-second and seamless AML (Anti-Money Laundering) check that happens before users deposit into any Nest vault. ### What You Need to Know * AML checks are required to deposit into Nest vaults and are powered by TRM Labs. * AML checks run on both the app and smart contracts (to ensure they can't be bypassed). * Policies are disclosed to asset issuers and protocols whose assets are available through Nest vaults.

Wallet restricted notification

### Freeze and Seize Capabilities Nest implements freeze and seize functionality directly in its smart contracts to enable compliance with global AML/ATF regulations. * **Freeze illicit funds**: Temporarily restrict transfers from wallets identified as illicit, preventing further movement while investigations proceed. * **Seize illicit assets**: Permanently redirect illicit funds to a designated recovery or authority wallet, similar to mechanisms in USDC and USDT smart contracts. Asset seizure capability can only be activated under a lawful order (e.g., federal law in the US). ### How It Works Nest uses [**TRM Labs**](https://www.trmlabs.com/), a leading blockchain intelligence provider, to run AML checks. Nest's compliance team defines the rules, and [**Predicate**](https://predicate.io/) applies them. ## GET /user/{address}/compliance > Checks compliance for a user and retrieves predicate message if compliant ```json {"openapi":"3.0.0","info":{"title":"Nest API","version":"1.0.0"},"servers":[{"url":"https://api.nest.credit/v1","description":"Nest API Server"}],"paths":{"/user/{address}/compliance":{"get":{"tags":["User"],"description":"Checks compliance for a user and retrieves predicate message if compliant","parameters":[{"schema":{"type":"string","pattern":"^0x[a-fA-F0-9]+$","description":"User address"},"required":true,"description":"User address","name":"address","in":"path"},{"schema":{"type":"number","default":1,"description":"Optional.
