  • Method Details

    • createAensDelegationSignature

      java.lang.String createAensDelegationSignature​(java.lang.String contractId)
      creates a delegation signature over "network id + account address + contract address" (concatenated as byte arrays)
      Parameters:
      contractId - the address of the contract (ct_...)
      Returns:
      the delegation signature that allows a contract to perform a preclaim for an AENS name on behalf of the configured keypair

    • createAensDelegationSignature

      java.lang.String createAensDelegationSignature​(java.lang.String contractId, java.lang.String name)
      creates a delegation signature over "network id + account address + name hash + contract address" (concatenated as byte arrays)
      Parameters:
      contractId - the address of the contract (ct_...)
      name - the AENS name (e.g. kryptokrauts.chain)
      Returns:
      the delegation signature that allows a contract to perform AENS related actions for a specific name on behalf of the configured keypair

    • createOracleDelegationSignature

      java.lang.String createOracleDelegationSignature​(java.lang.String contractId)
      creates a delegation signature over "network id + account address + contract" (concatenated as byte arrays)
      Parameters:
      contractId - the address of the contract (ct_...)
      Returns:
      the delegation signature that allows a contract to create and extend an oracle on behalf of the configured keypair

    • createOracleDelegationSignature

      java.lang.String createOracleDelegationSignature​(java.lang.String contractId, java.lang.String queryId)
      creates a delegation signature over "network id + oracle query id + contract address" (concatenated as byte arrays)
      Parameters:
      contractId - the address of the contract (ct_...)
      queryId - the query id (oq_...)
      Returns:
      the delegation signature that allows a contract to respond to a specific query on behalf of the configured (oracle) keypair

    • getAensCommitmentHash

      java.lang.String getAensCommitmentHash​(java.lang.String name, java.math.BigInteger salt)
      for claiming names with contracts it is required to provide the commitmentHash for an aens name
      Parameters:
      name - the AENS name to claim
      salt - the salt used in the pre-claim transaction
      Returns:
      the hash that needs to be wrapped in the `Hash` object (generated via contraect-maven-plugin)
