Lottery

⚠️ Experimental — generated with no human supervision by the daily MCP pipeline (Solidity→Gno port). Not audited. See r/moul/x/daily.

An idiomatic gno.land port of the classic Solidity Lottery contract.

Players Enter the current round (one entry per address per round — a second entry panics). Once a round has at least two entrants, anyone may DrawWinner, which picks a winner deterministically from the block height (ChainHeight() % len(entrants) over the deterministically-sorted entrant set), records it in the winners history, and opens a fresh round. Solidity's block.number-based pseudo-randomness maps to runtime.ChainHeight(), and msg.sender maps to unsafe.PreviousRealm().Address(). Render shows the open round, its entrants, and the table of past winners.

Example calls

# Two different accounts join round 1
gnokey maketx call -pkgpath gno.land/r/moul/x/daily/lottery/v0 -func Enter ...   # from alice
gnokey maketx call -pkgpath gno.land/r/moul/x/daily/lottery/v0 -func Enter ...   # from bob

# Anyone draws the winner and opens round 2
gnokey maketx call -pkgpath gno.land/r/moul/x/daily/lottery/v0 -func DrawWinner ...

Read-only helpers: CurrentRound(), NumEntrants(), HasEntered(addr).
