Web3 Balance

An extension of web3-go that is used for reading token or ether balances from the chain.

Example

eth, err := ethrpc.NewWithDefaults(ethClientURL)
b := balance.New(eth, 5)
block := fmt.Sprintf("0x%x", 7000000)

requests := []*balance.Request{
    &balance.Request{
        Address: "0xa838e871a02c6d883bf004352fc7dac8f781fed6",

        DefaultBlockParam:   block,
    },
