Keep your activity attributable.

A transaction can succeed without your Builder Code. Bao Toolkit checks for the missing credit.

What a new season needs

Release check

Recheck attribution when you add a mint, wallet flow, or payment path. Publish a new source audit and onchain evidence for the paths you enable.

The game’s published testnet evidence is historical. Season activity and current deployment verification are not connected.

How to read these numbers

Source audit: 8 Sept 2026 UTC, strict profile, 263 files. Revision ba9c458a4412; working tree clean. This is a local source audit snapshot, not the status of a hosted CI run or a complete proof of runtime behavior.

Transactions are deduplicated by network and hash. Coverage counts transactions that are both RPC verified and decoded with the expected Builder Code, divided by every transaction in the selected published sample. Empty samples have no coverage percentage.

Verification describes attribution evidence at snapshot time. It does not certify contract security, current deployment readiness, successful game actions, or the source of a player’s visit. Missing, invalid, unavailable, differently attributed, and unverified records remain in the denominator.

Snapshots update when a new proof set is published. This dashboard does not poll the blockchain. Season counts, unique players, revenue, and daily activity are not inferred from the sample.

Use Bao Toolkit alongside Base analytics

Base App automatically adds a registered app’s Builder Code. Outside Base App, builders integrate attribution themselves. A direct SDK setup can be enough for a simple app. Read the Base integration guide.

Bao Toolkit becomes useful when you want repeatable source checks, failing CI checks for attribution regressions, and reusable onchain evidence across supported transaction paths. It does not guarantee rewards, recover past unattributed transactions, or measure referrals from X.
