source ↔ deployed bytecode

prove what code is actually deployed.

420Verify reproduces Solidity builds and compares them with canonical chain evidence for an exact network, address, and runtime-code-hash binding.

verification is not an audit. A match does not mean a contract is safe, official, immutable, authorized, or non-malicious.
