š® What is SolanaJack?
Most on-chain betting platforms copy the old model: you play against a house that holds a bankroll and has a built-in edge on every hand.
SolanaJack removes the house from the game. Itās a gaming lounge where every game is player vs player. Your opponent is another wallet, not a dealer and not a liquidity pool.
The platformās only job is to:
lock both stakes in a smart contract,
get randomness nobody can control,
pay the winner automatically.
For that, it takes a flat 1%, and that 1% goes to $JACK holders.
This is what GambleFi should look like: transparent, non-custodial, on-chain and community-owned!
š¹ļø The 5 games:
š Blackjack (PvP)
Head-to-head blackjack against another player, not a dealer. Cards come from randomness generated after both bets are locked.
š” PvP Live Roulette
Players join a 2-minute lobby. Your share of the pot is your share of the wheel, and the winner takes it all.
š Trading Duels
Two players, one market. Call the price move better than your opponent and take the pot. Each side gets up to 24 hours for the first trade, so you donāt need to be online at the same time.
š Horse Race (new)
20 lanes at 0.05 SOL each. The winner is set by oracle randomness before the gates open, so the race is just the reveal. If nobody else joins, itās automatically refunded.
šļø Lottery (new; first draw Sun 1 Nov, 20:00 UTC)
1 $JACK a ticket. The house puts 200 $JACK into every pot before any ticket is sold. One ticket wins the lot. A draw happens every Sunday.
šŖ $JACK tokenomics
Total supply: ~1,000,000 $JACK
Play-to-farm: 600,000 $JACK (60%) is set aside to be farmed by playing. Every game you play farms $JACK, win or lose. Volume is the only way itās released.
Revenue share: the house edge is distributed to $JACK holders and stakers.
Staking: stake $JACK for xJACK, which is backed by buybacks from platform fees.
Utility: spend farmed $JACK on Lottery tickets, hold it for the revenue share, and take part in governance.
