# Compliance Zaïffer implements a multi-layered compliance framework to ensure responsible operation while maintaining user privacy. The protocol screens all addresses that interact with the system through both on-chain and off-chain mechanisms. ## **On-Chain Sanctions Screening** The protocol automatically blocks addresses on the Office of Foreign Assets Control (OFAC) sanctions list from interacting with Zaïffer contracts. This enforcement happens directly on-chain through the integrated SanctionsList contract, ensuring immediate and transparent compliance with regulatory requirements. More info on [Chainalysis Oracle](https://go.chainalysis.com/chainalysis-oracle-docs.html). Additionally, protocol administrators can add addresses to the on-chain restrictions as needed to maintain platform integrity and meet evolving compliance obligations. ## **Off-Chain Transaction Monitoring** Zaïffer integrates with [Chainalysis Know Your Transaction](https://www.chainalysis.com/product/kyt/) (KYT) services to monitor and index all protocol interactions off-chain. This provides comprehensive transaction analysis while keeping sensitive balance information encrypted on-chain, striking a balance between regulatory compliance and user privacy. --- # 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.
