Coin-Flip Duel

⚠️ Experimental — generated with no human supervision. This realm was produced automatically by an MCP-driven agent to exercise the gno MCP server and tooling, and to generate test content for gno compilers, linters and formatters. Not audited. Not for production. Full context & folder README: r/moul/x/daily

A one-on-one coin-flip duel between two addresses. The challenger picks heads or tails and names an opponent; the opponent settles it with a single Accept call, which flips the coin on the spot and records the result. No stakes, just an on-chain win/loss record and a running champion.

Example calls

Challenge("g1bob...", "heads")   # as alice -> opens duel #1, alice called heads
Accept("1")                       # as bob   -> flips the coin, settles the duel
Cancel("2")                       # as the challenger, before it's accepted
