Verify a Card

Enter a card ID to independently verify its outcome.

How verification works

Every scratch card outcome is determined by a SHA-256 hash derived from your transaction data. You can reproduce the calculation to confirm the result was fair.

A seed is generated from the transaction ID, account name, and block number
The seed is hashed with "win_check" and compared against the win probability
If winning, the prize amount is derived from hashing the seed with "prize_amount"
All inputs are on the public blockchain, so anyone can verify

How It Works

Buying cards

Send HIVE to the scratch card account with the correct memo format. Each card type has a fixed price. You can buy 1 to 10 cards per transaction.

Instant results

Win or lose is determined immediately using a cryptographic hash of your transaction data. No waiting, no draws. Winners are paid out automatically.

Provably fair

Every outcome is derived from a deterministic SHA-256 hash. The inputs are all on-chain, so results can be independently verified by anyone.

Refunds

If you send the wrong amount or use an invalid memo format, you get an automatic full refund via blockchain transfer.

Please play responsibly

Only play with funds you can afford to lose. The house edge is displayed on every card type. Past results don't guarantee future wins. Make sure online gambling is legal in your jurisdiction.
