  • Get the serialized bytes of the signable object. Serialized bytes can be used to recreate the object using methods on Gateway.

    Returns Uint8Array

  • Get the digest of the signable object. This is used to generate a digital signature.

    Returns Uint8Array

  • Get chaincode events emitted by transaction functions of a specific chaincode.


    • Optional options: CallOptions

      gRPC call options.

    Returns Promise<CloseableAsyncIterable<ChaincodeEvent>>

    The iterator should be closed after use to complete the eventing session.


    GatewayError Thrown by the iterator if the gRPC service invocation fails.
