We can simplify it to return (hexutil.Uint64)(api.e.blockchain.Config().ChainID.Uint64())

return (hexutil.Uint64)(chainID.Uint64())
}

// IsEIP155 returns whether the current chain is on or past the
// EIP-155 replay-protection fork block.
func (api *PublicEthereumAPI) IsEIP155() bool {
return api.e.blockchain.Config().IsEIP155(api.e.blockchain.CurrentBlock().Number())
