ethereum : A set of Ethereum specific tools

Overview

Install

go get github.com/cleanunicorn/ethereum/web3

Use

Connect to an Ethereum endpoint and ask for a block number

c := web3.NewClient(provider.DialHTTP("https://mainnet.infura.io/:8545"))

b, err := c.Eth.GetBlockByNumber("0x2", false)
if err != nil {
	fmt.Printf("Error getting latest block, err: %v", err)
	os.Exit(1)
}

fmt.Printf("Block: %#v\n", b)

Make raw calls

c := web3.NewClient(provider.DialHTTP("https://mainnet.infura.io/:8545"))

res, err := c.Provider.Call("eth_blockNumber", nil)
if err != nil {
	fmt.Printf("Error getting latest block, err: %v", err)
	os.Exit(1)
}
fmt.Println(string(res))
