The last buyer snags the whole pot.
Every round, the clock doubles.
Every trade of $SN4G earns creator fees. When the countdown hits zero, all of them go to whoever bought last — paid automatically, on-chain. Then a new round opens at twice the length.
Any buy of 0.01 SOL or more takes the snag. Hold it when the clock hits zero and the round's creator fees land in your wallet automatically.

Selling never touches the clock or the snag.

Only how late. Never how big.
One rule, enforced every round: be the freshest buy on the tape when the clock runs out.
The clock runs
Round one lasts five minutes. The countdown never resets mid-round — it just runs out.
Every buy takes the snag
Each buy of 0.01 SOL or more becomes the new last buyer. It doesn't matter how big — only how late.
Zero pays the snag
When the clock hits zero, every pump.fun creator fee the round earned is claimed and paid to the last buyer — by the on-chain vault, automatically.
Then it doubles
The next round starts instantly at twice the length — 5m, 10m, 20m, 40m... forever. Longer rounds, fatter pots.
no round ever goes unpaid — a round with no eligible buyer rolls its pot into the next one
The machine, end to end
Two chains, one game. Order flow and payouts live on Solana. The doubling clock, the public last-buyer record, and an ETH pot run inside a Uniswap v4 hook on Ethereum. The round engine is the bridge — and every step it takes is a public transaction you can audit.
You buy on pump.fun
$SN4G trades on pump.fun like any other coin — that's where the liquidity and your fills live. Every trade accrues creator fees in SOL. Those fees are the pot.
The oracle watches the tape
The round engine follows every trade in real time. Each buy of 0.01 SOL or more is a qualifying buy — the freshest one holds the snag.
Your buy is written on-chain. Twice.
The snag is recorded in the Solana settlement program
(record_buy) and mirrored into the v4 hook on Ethereum
(recordBuy) — your Solana wallet, on Etherscan, as the
on-chain last buyer.
Zero: the vault pays you
At the deadline the engine claims the round's creator fees and deposits
them into the program's vault. The program's settle pays the
winner from the vault — contract to wallet, one atomic transaction.
The hook settles too
A share of every round's fees is pushed into the hook's ETH pot
(fund), and its settle() doubles the on-chain
clock. The pot sweeps to the payout router and rides to the winner
alongside the SOL.
Doubled, in lockstep
Program and hook both double their clocks at every settle. The site reads the round straight from chain — the engine can't shorten a round or move a deadline.
Real mechanism, not a promise
SN4G is the first coin on Solana built on a Uniswap v4 hook design — the game lives in deployed, source-verified code, not in a group chat. Both halves are on mainnet.
Settlement program
An on-chain program holding the round state — round number, deadline,
doubling duration, last buyer — with a vault that pays the winner when
anyone cranks settle after the deadline. Deployed on
Solana mainnet.
The Sn4g hook
The mechanism as a Uniswap v4 hook on the canonical PoolManager:
every qualifying pump.fun buy is mirrored into it, a share of every
round's fees feeds its pot, and settle() doubles the
on-chain clock. The address itself encodes the hook's permissions —
and the source is verified, so you can read the whole game.
