# Restricted Wallets **cSigma Edge** is committed to compliance with global regulatory standards. Wallet addresses that are listed on any **sanctioned or embargoed lists**, including those imposed by the United States (**US**), European Union (**EU**), or United Nations (**UN**), are prohibited from interacting with cSigma Edge smart contracts. These sanctions apply to entities or individuals listed on economic or trade embargo lists, and any wallet associated with them will be blocked from performing transactions on cSigma Edge. To enforce this, cSigma Edge uses the [**Chainalysis Oracle**](https://go.chainalysis.com/chainalysis-oracle-docs.html), a smart contract that automatically checks whether a wallet address appears on a sanctions list. If an address is flagged by the oracle as belonging to a sanctioned entity, it is immediately **blocked from engaging in any activity** within the cSigma Edge protocol. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
