The house holds nothing

Create an offer or take one from the lobby. Your stake locks in a program-owned escrow — no human can touch it. Flat $0.10 entry, always.

Both stakes commit to a block that doesn't exist yet. Its hash decides the flip — unpredictable to you, your opponent, and to us.

2x your stake, paid by the program in the same breath. Every result is public — audit any flip, forever, on-chain.

“The coin is a block that hasn’t been written yet. Nobody — not even the house — knows how it lands.”
