Frequently Asked Questions
Get clear answers on how our confidential transaction service works, from integration to security.
We implement zero-knowledge proofs (ZKPs) and trusted execution environments (TEEs) to enable confidential transactions. Our service uses zk-SNARKs for on-chain privacy, ensuring transaction amounts and participant addresses are hidden while maintaining cryptographic proof of validity. For off-chain privacy, we leverage secure enclaves to process sensitive data. The result is a settlement layer that integrates with your existing DeFi or payment stack, providing privacy without sacrificing composability or auditability.
