# Integrate leaderboard contests

Read [contests](https://test.playmos.io/docs/contests.md) and the [SDK reference](https://test.playmos.io/docs/reference.md) before selecting methods. Contest lifecycle and in-app purchases are separate integration paths.

Use the developer's actual game, pool, series, entry price, prize split and payout table. Do not substitute internal demo rules or invent ownership. Keep pool, series, epoch and chain context with every operation and saved recovery record. New rules create a new contest; do not mutate a live contest's terms.

Preserve the documented entry identity and round identifiers across client and backend. A local send or receipt alone is not admission: reconcile through the documented confirmation path. Distinguish pending entry, confirmed admission, settlement and claimable winnings.

Keep score authority on the studio backend; do not accept an untrusted client's score as proof. Use the documented settlement and prize claim paths, keeping secrets server-side and wallet signatures under developer control.

Default new integrations to Base Sepolia. Prepare code and tests within the requested scope; provisioning a funded contest, signing, spending and production publication require developer authority. Report the exact context and evidence for each lifecycle step verified.
