Solana Coinflip — Heads or Tails

Solana Coinflip is the simplest on-chain game: pick heads or tails, flip for a 50/50 chance, and double your SOL minus a small 2% fee. Outcomes are provably fair and paid instantly.

Each flip is fixed by a pre-committed seed that is revealed after the round closes, so the heads-or-tails result can be verified on-chain.
