Fees

Each scratch card costs 0.02 SOL (~$5).

The protocol takes a 10% platform fee from scratch cards sales.

Each "stack" of cards incurs a small additional cost due to Solana rent fees. A stack refers to a single purchase containing one or more scratch cards. These rent fees are automatically returned to your wallet when all cards in the stack are scratched.

Specifically, for each stack

• 0.00823 SOL in rent for a randomness account (we use this for verifiable randomness). You get 0.006 SOL of this back once the cards in the stack are scratched.

• 0.0039 SOL for the scratch card stack. You get this back when you scratch the cards too.

If you want to buy multiple scratch cards, we recommend buying them in bulk to lower up front cost.
