Remote Procedure Call (RPC)

RPC API Reference

By default, RPC API listens on 20336 port.

The following option can be used to change the port at which the client side RPC API listens:

ontology --rpcport 1024

The following option can be used to stop the client side RPC service:

ontology --disable-rpc

Remote Procedure Call (RPC), also known as function call or subroutine call, are used on one machine on a network to request services from another machine without the need of detailed network information.

Response parameters

Field

Description

TxHash

Transaction hash

State

Transaction execution status, 0 indicates execution failure, 1 indicates execution success

GasConsumed

Amount of gas consumed for execution

Notify

Contract events triggered by the transaction

The two fields within Notify:

Field

Description

ContractAddress

Contract address where the event occurred

States
