Diff two on-chain versions

Load upgrade history for a program, select Version A and Version B, then reconstruct and compare bytecode. Artifacts are not marked verified unless independently proven.

Tip

Prefer programs with distinct buffers per upgrade and complete Write history on your RPC. Large binaries can take several minutes.

Program
Version A — before
Version B — after

Reconstruction requires complete buffer Write history and a bounded deployment cycle. Results include full SHA-256 provenance — not verified-build attestation.
