CHAINLINK PRIVACY STANDARD
Private transactions on any blockchain
Execute private payments, tokenize RWAs, distribute data, and prove compliance without exposing identities, proprietary data, or business logic.
Privacy-preserving connectivity
Transact across blockchains, enterprise networks, and leverage Chainlink services while keeping data, logic, and transaction details private.
Compatible with public and private chains
Access confidential compute on any blockchain without migrating your smart contracts—build once, connect anywhere without vendor lock-in.
Verifiable and performant confidential computing
Combine trusted execution environment performance with decentralized compute, multi-cloud deployment, and advanced encryption for institutional-grade security and scale.
Decentralized secrets management
Reduce exposure and protect proprietary information, as all your sensitive data is threshold-encrypted, with only the minimum required inputs ever decrypted and processed.
