Bit Flip
Trustless coin flips on Bitcoin L1. No middleman, no custody. Provably fair with commit-reveal and covenant escrow.
How it works
Pick & Commit
Choose Heads or Tails. A random secret is generated and committed via SHA256.
Fund Escrow
Both players send BTC to a shared covenant escrow. Transaction pinning enforces the rules.
Reveal & Win
Secrets revealed. Script enforces the winner. Payout is instant, on-chain, verifiable.

Why Bit Flip
No Custody
Your BTC never touches a server. Funds are locked in Bitcoin Script, not a hot wallet.
No Oracles
Winner determined by secret byte lengths, enforced entirely by Bitcoin consensus.
Provably Fair
Commit-reveal protocol. Both secrets locked before either is revealed. Verify any game on-chain.
Bitcoin L1
No sidechains, no bridges, no tokens. Pure Bitcoin Script with Bino Hash covenants.
