Introduction

This is the Ethereum Golang API which connects to the Generic JSON-RPC spec.

You need to run a local or remote Ethereum node to use this library.

Here is an open source case Web3 Studio reference under.

Client

go get github.com/6boris/web3-go

package main

import (
  "context"
  "fmt"
  "github.com/6boris/web3-go/client"
  "github.com/6boris/web3-go/pkg/otel"
)

func main() { 
  otel.InitProvider()
  ec := client.NewPool(client.GetDefaultConfPool())
  chainID := int64(1)
  v, err := ec.GetClient(chainID).ClientVersion(context.Background())
  if err != nil {
    panic(err)
  }
  fmt.Println(fmt.Sprintf("ChainID:%d ClientVersion:%s", chainID, v))
}


/*
Output:
    ChainID:1 ClientVersion:Geth/v1.11.5-omnibus-65be78cc/linux-amd64/go1.19.7
*/
