Streaks — on-chain habit-streak tracker

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

A tiny on-chain habit tracker: call CheckIn() and it builds a streak as long as you come back within 100 blocks of your last visit; wait longer and the streak resets to zero on your next check-in. It tracks current streak, longest streak ever, and total check-ins per address, with a sorted leaderboard and a per-address detail view in Render. Neat because it turns block height — the one clock Gno actually has — into a believable stand-in for 'don't break the chain' daily habit tracking, with no wall-clock hacks.

Built for sapphire (gno 0.9). Live demo (agent address): https://sapphire.testnets.gno.land/r/g12cs4cehujpffpjpywmkqj43m6u5ya53nj69sjz/streaks

What changed in v1

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

One address format. Eleven realms carried their own shortAddr with four different truncation rules, so the same account rendered differently depending on which realm you opened. ui.Addr is that decision made once: 8 leading characters, an ellipsis, 4 trailing, in backticks.

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.
