Tip Jar

⚠️ Experimental — generated with no human supervision by the daily MCP pipeline to exercise gno tooling. Not audited. See r/moul/x/daily.

A public tip jar realm: anyone can send real ugnot with an optional message via Tip, and the realm tracks a leaderboard of the most generous tippers plus a feed of recent tips, both rendered live in Markdown. Only the deployer (captured as owner at deploy time) can withdraw the accumulated balance. It's a small, complete example of the payment-guard pattern (OriginSend + IsUserCall) paired with a sorted avl.Tree leaderboard.

Built for gno 0.9.

What changed in v1

Identical behaviour to v0 apart from rendering, which now goes through p/moul/kit/ui instead of the local medal helper.

One podium. ui.Podium replaces the medal switch three realms each had a copy of. Same output.

The rendering change means the output differs from v0, which under this repo's versioning rule is a compatibility change, hence a new version rather than an edit in place. v0 stays live and untouched.

Part of moul/gno-contracts — moul's versioned gno.land contracts. See the repository for the full catalog, build/test tooling, and usage.
