Inspect EVM selectors and proxy contracts, compare bytecode and ABI evidence, and use REA for deeper offline smart-contract analysis. Guides check selectors, proxy behavior and verification mismatches. The REA example starts from a contract you compile with solc so inferred arguments can be checked against compiler output; inference does not recover names or source.
Etherscan Bytecode Does Not Match? Fix a Failed Hardhat or Forge Verify
Etherscan bytecode does not match, or hardhat verify failed? Read the solc version from the deployed code, then use a nine-build comparison to tell a source mismatch from a wrong compiler setting.
How to Check if a Contract Is a Proxy, Even When It's Unverified
How to check if a contract is a proxy when Etherscan shows no verified source: spot EIP-1967 proxies and EIP-1167 clones in the bytecode, find the implementation, and read a token's admin functions.
