This signature logs you in. It costs no gas and moves no tokens. Never share your recovery phrase.

Checking your account…

Connect your wallet, choose a token you hold and call heads or tails.

Get a feel for the game

Pick heads or tails and set your stake. Each result is saved before the animation starts, so you can check it later using your receipt and the revealed seed.

The house gets a cut

At a 2% house edge, a winning 1-credit bet pays about 1.96 credits including your stake. Your bet slip shows the current edge and exact payout before you play.

Check the damn math

Once a seed is retired and its bets are finished, it’s revealed so you can use it with your receipt to recalculate the flip.

Check a receipt

Bring your bags

Pick a token from your wallet on Ethereum, Robinhood or Solana and receive any payout in that same token. Availability depends on price coverage, compatible transfers and house funds. Token play is 18+.

Check your flip

Paste a revealed seed and your receipt. We’ll rerun the math in your browser so you can see whether it matches. There’s a step-by-step view and the code behind it.

  1. Before the betSave the seed hash

    The house posts a hash of its secret seed before you bet. Save it to check that the revealed seed matches.

  2. At settlementKeep the receipt

    Your receipt records your client seed, flip number and result. You’ll need them to check the flip.

  3. After rotationRecalculate the flip

    Once all bets using that seed are finished, the old seed can be revealed. Check its hash, then recalculate your result.

What a match proves

The supplied seed matches the supplied commitment, and the inputs reproduce the recorded side. Save the original commitment independently: this calculator cannot establish when a hash was published.

Where the chain fits

A chain escrow will lock the stake, pay an authorized server result, or allow a refund after a deadline. This verifier checks the seed proof, not a payout or server signature. Live escrows are not connected yet.

The published recipe

We follow Stake’s seed and HMAC mechanism, four-byte conversion and Flip mapping. Here, each bet consumes one flip at cursor zero, with a new nonce for the next bet.

Set your limits

Choose a daily stake budget or take a break whenever you need one. Read the terms before playing with real tokens.

Player controls & terms

Same token in and out On Solana, a token win returns your stake plus additional tokens bought by the house. A loss sells the stake for SOL. SOL bets pay directly. Compatible tokens need current prices, swap routes and enough house capital.

How the flip works The server combines its committed seed with your client seed and flip number using HMAC-SHA256. You can check the result after the seed is revealed. The escrow follows signed results; it does not recalculate the flip.

Where you can play Check the published terms for eligibility before playing with real tokens.

Age requirement You must be 18 or older to play with real tokens.
