    • createAensDelegationSignature

      public java.lang.String createAensDelegationSignature​(java.lang.String contractId)
      Description copied from interface: DelegationService
      creates a delegation signature over "network id + account address + contract address" (concatenated as byte arrays)
      Specified by:
      createAensDelegationSignature in interface DelegationService
      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

      public java.lang.String createAensDelegationSignature​(java.lang.String contractId, java.lang.String name)
      Description copied from interface: DelegationService
      creates a delegation signature over "network id + account address + name hash + contract address" (concatenated as byte arrays)
      Specified by:
      createAensDelegationSignature in interface DelegationService
      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

      public java.lang.String createOracleDelegationSignature​(java.lang.String contractId)
      Description copied from interface: DelegationService

      Specified by:
      createOracleDelegationSignature in interface DelegationService
      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

      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
