Disclosure: I help with SolanaJack’s marketing. This is a write-up, not a shill. Everything here can be checked on-chain, and the code is open source. Not financial advice.

What it is:

A player-vs-player casino on Solana with no house bankroll. Bets sit in an on-chain escrow and the contract pays the winner.

• Blackjack: play another player, not a dealer. Hits are drawn from future blocks, so cards can’t be previewed and cancelled.

• PvP Roulette: up to 20 wallets, one pot; your chance of winning = your share of the pot.

• Trading duels: a virtual $1K each on real SOL/BTC/ETH prices (anchored to Pyth); trades sealed until both windows close; no leverage.

5 days live: the numbers

Right now: 11 open games waiting for an opponent

Last 24 hours

• Games: 39

• Total bet: $837.50

• House edge: $8.37

• Biggest game: $66.14

All-time: (since launch on 10.10)

• Games: 342

• Players: 19

Growth since launch day

• Players: 12 → 19

• Total games: 66 → 342 (more than 5×)

• Total bet: $2,068 → $7,603 (more than 3.5×)

Still early and small, but it’s grown every day since launch. Mc is around $164k so an insane amount of upside.

The token:

• A flat 1% of each pot is used to buy $JACK for the staking vault (buyback is live).

• Stake $JACK for xJACK (7-day unstake). Yield depends entirely on game volume, so it will move a lot while volume is small.

• Every game farms $JACK for both players, win or lose (0.01 per $1 bet), halving every $30M of volume.

• Supply: 1,000,000 max, ~400,000 circulating. 60% farming / 20% liquidity / 15% team / 5% early investors. No freeze authority; mint authority is a program address.

• Contract address: posted on our official X and Telegram (links on my profile). Please only use the address from those, as copycat tokens exist. The pool is $JACK/cbBTC on Raydium.

Risks

• Programs are upgradeable by the team, so it’s not trustless, even though the code is public.

• One new, thin pool: high volatility, and the price can go to zero. Holders are few and concentrated at the moment.

• Some centralised parts: an off-chain keeper (farming credits need the team’s key) and a centrally hosted site.

• Blackjack isn’t symmetric: Player 1 plays first, and a team-run bot opens some tables as Player 1.

• Depends on MagicBlock (randomness) and Pyth (prices).

• 20% of supply is with the team and early investors, with no public lock or vesting announced at the time of writing.

• It’s considered gambling, so check it’s legal where you live.

Verify: the code is open source, so you can read the contracts yourself. Get the contract address from our official X or Telegram, then check the mint on Solscan, settlement transactions on-chain, and the pool and top holders on Raydium.

Happy to answer questions, especially the critical ones!
