ZK-Rollup AML: Frequently Asked Questions
Get clear, specific answers about our privacy-preserving AML solution for ZK-Rollups, from implementation to compliance.
Our solution integrates a privacy-preserving AML module directly into your ZK-Rollup's proof generation and state transition logic. We use zero-knowledge proofs (ZKPs) to validate that transactions comply with configured risk rules (e.g., sanctions screening, transaction limits) without revealing the underlying user data or transaction details to the sequencer or verifiers. The system operates on a pre-defined set of compliance rules, and a validity proof attesting to rule adherence is bundled with each batch's ZK validity proof.
