State Contract addresses​

For situations where one needs to publish data on the blockchain, such as creating an MTP-type credential, generating on-chain proofs and making credential revocations effective, it is important to have the following Smart Contracts addresses:

  • Mainnet -> 0x2F4E9C03e077F923BeEe6102314e6C01228C67EA
  • Testnet(Origin) -> 0x8c0De84cD393b92f243B82c659cB1E36d0Ac1a1F

CredentialAtomicQuerySigValidator​

CredentialAtomicQuerySigValidator.sol - Github

The CredentialAtomicQuerySigValidator contract is used to verify any credential-related zk proof generated by user using the credentialAtomicQuerySigV2OnChain circuit. The contract only verifies proofs based on credential of type Signature

The core of the contract is its verify function that takes the proof generated by a user and executes a set of verifications:

  • Verifies that the proof is valid. This verification is actually performed inside theverifierSig contract which is automatically generated using circom.
  • Verifies that the input used to generate the proof matches the query associated to that specific Request.
  • Verifies that the user's and the Issuer's identity states are valid based on the State Contract.

The CredentialAtomicQuerySigValidator executes the same set of verifications of the Verification Library. The former is required when performing on-chain verification while the latter is required for off-chain verification.

CredentialAtomicQueryMTPValidator​

CredentialAtomicQueryMTPValidator.sol - Github

Performs the same set of verifications of the CredentialAtomicQuerySigValidator but for credential of type MTP.
