	for addr, account := range accounts {
		codedAddr := common.Hex2Bytes(addr)
		accountState := statedb.CreateAccount(common.BytesToAddress(codedAddr))
		accountState.SetBalance(common.Big(account.Balance))
		accountState.SetCode(common.FromHex(account.Code))
		statedb.UpdateStateObject(accountState)
	}
