ⓘ RAIN Channels — instant, two-party provably fair — ⚡ CHANNEL mode (default): one tx opens a session; every hand is then instant and free. Each card is a mutual commit-reveal — neither you nor the house can know or pick a card alone — and every state is signed by both sides, so the chain enforces your payout even if anyone vanishes. Disconnected? You have 3 minutes to reconnect and resume. Abandoning an open hand forfeits only that hand's stake; if the house stalls, you get the hand back plus compensation from its bond. Win pays 1:1, blackjack 3:2, push refunds — the 1.25% fee applies to losing stakes only and settles on-chain at session close. ⛓ PYTH mode is the original per-action on-chain flow (V3 contract), kept as a fallback.
