One a day. Rub it off.

The prize is decided and signed when the card is dealt. Scratching only reveals it. Claiming sends it to your wallet in one transaction.

The vault is not funded yet, so cards are dealt in demo mode and move nothing. Everything else runs for real.

Odds per card: 60% common ($0.50), 30% rare ($2), 9.9% epic ($10), 0.1% legendary (one NVIDIA share, holders of 5,000 $SCRATCH only). A tier is only dealt when the vault can pay it. The maths.
