Core Contracts Release 8

Hi everyone,

The cLabs team is happy to announce Core Contracts Release 8!


The upgrade includes the following changes described with more detail in the release notes:

  • Adds FederatedAttestations.sol: Similar to Attestations.sol, this new contract records mappings from bytes32 identifiers to addresses, and is used primarily to resolve off-chain identities like phone numbers to addresses so that users can more easily send each other payments.
  • Adds OdisPayments.sol: While the original ODIS rate limit imposed this cost by calculating quota as a function of on-chain transaction history, the new rate limit will impose this cost by requiring direct payments to a smart contract.
  • Updates Escrow.sol: To allow escrowed payments to be gatekeeped by the ‘trusted’ issuer logic introduced in FederatedAttestations.sol

We look forward to hearing your thoughts!
