Ethereum Bytecode Cracker

Reproduce byte-for-byte exact bytecode for unverified frontier-era Ethereum contracts (Aug 2015 - mid 2016).

What "Cracked" Means

Byte-for-byte match of both creation and runtime bytecode. Not decompilation, not documentation, not "figuring out what it does." A contract is cracked ONLY when compiled source produces the exact on-chain bytecode.

Workflow Overview

1. Fetch on-chain bytecode (creation + runtime)
2. Extract selectors and identify functions
3. Trace bytecode to understand storage layout, logic, events
4. Reconstruct Solidity source
5. Compile and compare across compiler versions + optimizer settings
6. Permutation crack function declaration order (critical for optimizer output)
7. Publish via the verification pipeline
