Overview

Package jsonrpc contains the implementation of the JSONRPC service which is called by Ethereum clients (e.g. Metamask).

The most relevant types in this package are:

  • EthService, NetService, DebugService, etc. which contain the implementations for the `eth_*`, `net_*`, `debug_*`, etc., JSONRPC endpoints. Each endpoint corresponds to a public receiver with the same name. For example, `eth_getTransactionCount` corresponds to EthService.GetTransactionCount.
  • EVMChain, which provides common functionality to interact with the EVM state.
  • ChainBackend, which provides access to the underlying ISC chain, and has two implementations:
  • WaspEVMBackend for the production environment.
  • [solo.jsonRPCSoloBackend] for Solo tests.

package jsonrpc implements JSON-RPC endpoints according to https://eth.wiki/json-rpc/API

) (*rpc.Server, error)

func RPCMarshalBlock 

func RPCMarshalBlock(block *types.Block, inclTx, fullTx bool) (map[string]interface{}, error)
