$PAYBACK
The coin that pays you back for losing.
Close a trade at a loss and you get a quarter of your fees back. Then, every 15 minutes, one losing wallet wins the rest of the pot, drawn by a Solana block nobody can predict. Every payout is on-chain, tracked live below, and built so it can't be farmed.
Every buy and every sell on pump.fun pays a fee: 1.25% on the bonding curve, and 0.30% to 1.25% after graduation depending on market cap. The dev, the snipers, the bundles and the paid callers take the profit. Everyone else pays the fee on the way in, pays it again on the way out, and eats the loss.
The people who lose the most pay the most fees, and they get nothing back.
Wallets, accounts, “small holders”. Free to create, so infinitely fakeable.
Holdings, buy size, PnL. Always recoverable, so you can fake it by moving it between your own wallets.
Gone the moment you pay them. The only way to fake paying a fee is to actually pay it.
So $PAYBACK pays back a share of the fees you really paid, and puts the rest of the pot up as a jackpot for one loser. Only wallets that were trading before it existed get tickets, and that history can't be made after launch. On average, faking a loss always costs more than it returns.
From the first trade, every buy and sell on the bonding curve and the PumpSwap pool is replayed here. Every claim into the treasury and every payout out of it is read straight from Solana and listed below as it happens.
The site reads the coin's full trade history from pump.fun's own trade feed, covering the bonding curve and the PumpSwap pool, which are the only venues that pay creator fees. Each wallet's buys and sells are replayed in order at average cost.
Tokens a wallet sells beyond what it bought (tokens that arrived by transfer) carry zero cost. Selling them always shows a profit, so moving a bag between your own wallets can never create a loss.
A sell counts when it loses at least 5% of its cost basis. Its weight is the fees that wallet actually paid on that round trip: the buy fees attached to the tokens it sold, plus the sell fee, worked out per trade from pump.fun's published schedule. Every loser gets 25% of those fees back, paid first.
Everything the fees back don't use goes to one losing wallet, drawn when the epoch closes. Tickets are weight × veteran score: how long the wallet had been active, and how much it had traded, before $PAYBACK launched. That history is fixed in the past and can't be made after launch. A wallet made to farm this coin gets fees back and zero tickets.
The draw uses the hash of the first Solana block at or after the epoch closed. Nobody knows it in advance, and anyone can re-run the draw from the block.
weight = buy fees on sold tokens + sell fee tickets = weight × veteran score back = min( pot × weight / Σ weight , 0.25 × weight ) jackpot = min( pot − Σ back , 0.65 × Σ tickets ) winner = sha256(blockhash:epoch) → tickets, address order
Whatever isn't paid rolls into the next epoch, so a quiet epoch makes the next jackpot bigger. An epoch only settles once every loser has a veteran score and the draw block is final, so a result never changes after it is shown.
pump.fun pays creator fees to the wallet that created the coin: the treasury. The treasury can only pay out what pump.fun has sent it: claimed fees minus what has already been paid. If claims ever fall short, every wallet gets the same fraction of what it is owed and the rest stays owed until the next claim. Amounts under 0.001 SOL keep building up until they clear it.
To fake a loss you have to trade, and every trade pays fees. The jackpot is capped so that fees back plus your expected share of the jackpot stay under 90% of the fees you paid. On average, every fake loss loses money, even with a drawer full of aged wallets. Fresh wallets don't even get a ticket.
Buy 1 SOL on the curve, sell for 0.6 SOL. Fees paid: 0.0125 + 0.0075 = 0.0200 SOL. Guaranteed back: 0.0050 SOL. Plus a ticket in that epoch's jackpot, which pays the whole pot to one loser.

$PAYBACK pays back a share of trading fees and a jackpot to one loser per epoch, funded only by creator fees the coin actually earns. It does not refund losses, promise returns or pay anyone for holding. Memecoins are extremely risky. Only trade what you can lose.
