[Bug] Contract interactions through `#[sol(rpc)]` do not set tx's `from` field about alloy HOT 4 CLOSED

demo to reproduce: https://github.com/StackOverflowExcept1on/alloy-bug/blob/master/src/main.rs

from alloy.

We should probably call SignerFiller before GasFiller to solve this problem. Here's how it works now:

from alloy.

I haven't researched this deeply, but my best guess is why this is happening: GasFiller doesn't set from field when estimating gas costs. This can lead not only to this problem, but also to an incorrect gas limit. Imagine a smart contract that, for example, does some computational work if msg.sender == owner.

// SPDX-License-Identifier: UNLICENSED
pragma solidity ^0.8.25;

contract Counter {
    uint256 public number;

    function increment(address expectedAddress) public {
        if (msg.sender == expectedAddress) {
            while (true) {}
        } else {
            number++;
        }
    }
}

from alloy.

I also made another demo that doesn't work correctly in alloy: https://github.com/StackOverflowExcept1on/alloy-bug/blob/gas/src/main.rs. Alloy does not correctly calculate the gas limit and the transaction fails: https://holesky.etherscan.io/tx/0xf8dcd7ce7f92ec4dca95b0e5c1343668d5d7eee65a3f156e9806c881e1b1626a
