I'm using MetaMask to connect to Rinkeby and I'm deploying the contracts via Remix. When I call the function returnsenderbalance it returns


rather than my balance in Wei. The code is below:

pragma solidity ^0.4.11;

contract returnbalance{
    function returnsenderbalance() constant returns (uint){
        return msg.sender.balance;

    Can confirm behaviour with contract deployed here Could not find a solidity version where it does not happen, though works as expected in the Javascript VM. currently looking through bytecode – o0ragman0o May 29 '17 at 2:01

    function eventSenderBalance() {SenderBalance(msg.sender, msg.sender.balance); } logs the correct balance. – o0ragman0o May 29 '17 at 2:14
  • Does anyone want to chime in and describe how this was ultimately resolved? I'm thinking compiler and curious about the details. – Rob Hitchens Oct 12 '18 at 4:18

This is related to:


func (b *EthAPIBackend) GetEVM(ctx context.Context, msg core.Message, state *state.StateDB, header *types.Header, vmCfg vm.Config) (*vm.EVM, func() error, error) {
===> state.SetBalance(msg.From(), math.MaxBig256)
vmError := func() error { return nil }
context := core.NewEVMContext(msg, header, b.eth.BlockChain(), nil)
return vm.NewEVM(context, state, b.eth.chainConfig, vmCfg), vmError, nil

math.MaxBig256 == 115792089237316195423570985008687907853269984665640564039455084007913129639935

Is a constant in Geth( common/math/big.go)
