Whitepaper

The Mechanism

PumpSpin is a financialised gambling loop built on token economics. Gameplay is capital allocation. Odds are distribution. Rewards are liquidity.

The Loop

01

Buy & Hold

Acquire the native token on Solana. Token balance determines draw eligibility and weighted odds.

02

Enter the Draw

Every ~20 minutes an automated jackpot cycle opens. No manual action — holding is participation.

03

Receive Rewards

Casino fees pool into the jackpot. Winners receive on-chain payouts direct to their Phantom wallet.

Core Mechanics

Token-Native Gambling

All bets are denominated in the native Solana token. No stablecoins, no fiat bridges — entry, play, and payout live entirely on-chain.

Fee Redistribution

Creator and trading fees are pooled automatically. The pool is redistributed to participants as jackpots and periodic rewards — no manual intervention.

Holder-Weighted Odds

Probability of winning scales with token holdings. More tokens = larger weight in the weighted-RNG selection — incentivising accumulation.

Automated Draw Cycles

On-chain logic triggers draws on a fixed schedule. The casino loop runs continuously with no operator input required between rounds.

On-Chain Transparency

Every reward distribution is a Solana transaction. Verifiable on-chain, publicly auditable — no hidden house mechanics or opaque ledgers.

Solana Settlement

Near-instant finality and sub-cent fees. Winnings settle in seconds, not days — pure velocity with no withdrawal queues.

House & Staking

250 SOL House Requirement

The casino requires a minimum seed bankroll of 250 SOL held by the house contract before the first round opens. This ensures the protocol can cover max-payout draws without insolvency risk. Once the bankroll threshold is met, staking unlocks and $SPIN holders begin earning rewards from every bet placed.

APR figures assume ~200 SOL average daily casino volume and a 4% rake, with 30% of fees redistributed to stakers. Base emission APR (18%) is fixed for 24 months. Fee-share APR (~28%) is variable — it rises with volume and falls if volume drops. Weekly yield figures are derived from annual APR ÷ 52. Actual payouts depend on total staked supply and protocol revenue. Not financial advice.
