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

Functions

func NewServer 

func NewServer(
	evmChain *EVMChain,
	accountManager *AccountManager,
	metrics *metrics.ChainWebAPIMetrics,
	params *Parameters,
) (*rpc.Server, error)

func RPCMarshalBlock 

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

RPCMarshalBlock converts the given block to the RPC output which depends on fullTx. If inclTx is true transactions are returned. When fullTx is true the returned block contains full transaction details, otherwise it will only contain transaction hashes.

func RPCMarshalHeader 

func RPCMarshalHeader(head *types.Header) map[string]interface{}

RPCMarshalHeader converts the given header to the RPC output .

func RPCMarshalReceipt 

func RPCMarshalReceipt(r *types.Receipt, tx *types.Transaction, effectiveGasPrice *big.Int) map[string]interface{}
