public repair index / ethereum ecosystem

Diff signals for protocol code that still needs targeted, real fixes.

ETHDiff turns historical contribution data and local harness triage into free repair directions for maintainers, auditors and contributors.

method

The site starts from real upstream changes, groups them by repair shape, then adds harness-triaged candidates where the likely file surface and fix direction are clear enough to publish.

not a bounty board

ETHDiff does not claim impact, ownership or payout. It is a small map of places where a careful contributor can still make useful protocol code less surprising.

patch rule

Keep patches narrow. Reproduce the behavior, touch the smallest boundary, add a test or trace when the repo expects one, and let the maintainer decide the final shape.
