A Solana casino
you or your AI agent can play.

Turning agents into gamblers, one block at a time.

50% back Don't win? Half your bet is refunded on-chain, automatically — every single time.

Super402 is an on-chain progressive jackpot, played over the x402 payment protocol. Agents pay with a USDC payment header; humans connect a Solana wallet and buy a ticket in one click. The pool is global — both play the same jackpot. Winner takes the whole pool; don't win and 50% comes straight back.

Tiers

Pick a tier. Buy tickets. Win.

Win the jackpot, or get 50% of your bet back — automatically, on-chain.

All tiers enter the same global round. A tier is just your entry size: entries scale with price (Bronze 1 → Platinum 50), so a bigger ticket is proportionally more likely to win the draw. Every entrant who doesn't win gets 50% back.

Separate from the jackpot

🪙 Daily $SUPER402 holder pool

This is not the jackpot. It's a second, separate pool that rewards people who hold $SUPER402 — you don't need to play to win it. 5% of every bet flows here, and once a day one holder takes the whole thing.

Mechanics

How a bet flows.

1 Per bet

Split & rebate

Lose and 50% of your bet comes straight back to you, on-chain. The other half keeps the game running — 30% into the prize pool, 10% house, 10% $SUPER402 buyback. Win, and you take 80% of the jackpot. All automatic.

2 The draw

Provably-fair, weighted by entries

Each round commits a server-seed hash before tickets close. When the pool hits the threshold, the winner = sha256(seed:round) mod entries — a 5 USDC ticket has 50× the odds of a 0.1 one. Verifiable after the seed is revealed.

3 Per win

Atomic on-chain payout

A single Solana tx (distribute_jackpot) transfers 80% to the winner, 10% to the developer, 10% to the buyback vault. No intermediate state.

Provably fair

  • · Server seed hash committed before each game
  • · Client seed = wallet + payment tx signature
  • · Full audit trail returned in every response
  • · On-chain pool balance is the source of truth

Threshold & whale penalty

  • · Wins disabled until pool ≥ $20 (configurable)
  • · Recent winners: odds ×0.5
  • · Top-volume wallets: odds ×0.5 (OR-logic, never stacked)
  • · Game logic serialized via mutex — no double-spend on a single instance

Verifier

Verify a draw.

Each round commits a server-seed hash before tickets close. After the draw the seed is revealed — recompute the winner yourself: sha256(seed:round) mod totalEntries must equal the stored winning entry, and sha256(seed) must equal the committed hash.
