How it works

$PAYOUT is a pump.fun coin. Every trade of a pump.fun coin pays a small creator fee. For $PAYOUT, pump.fun fee sharing sends those fees to one treasury wallet, and an engine passes them on to holders.

1. Collect. Every 5 minutes the engine triggers pump.fun's fee distribution, which pays the creator fees that have built up into the treasury wallet.
2. Snapshot. It reads every holder's balance from the chain and looks up how long each wallet has held without selling.
3. Weigh. Each eligible wallet gets a weight: its balance, up to the cap, times its multiplier.
4. Pay. The pot is split by weight. 60% of each wallet's cut is sent in SOL at once and 40% is credited to its vault.
5. Record. The round is written to a public file, and the file's hash is written into the payout transactions.

A round is recorded whenever there is something to pay. If no fees came in and nothing unlocked, the engine checks again 5 minutes later.

Exact rules

The formula

weight  = min(balance, 1% of total supply) x multiplier
cut     = round pot x weight / total weight of all eligible wallets
instant = 60% of cut, sent in SOL in the same round
vault   = 40% of cut, unlocks exactly 24 hours later

The round pot is the creator fees claimed since the last round plus the forfeit pot. All amounts are computed in lamports with whole-number arithmetic. Any remainder from rounding, always less than one lamport per wallet, stays in the pot for the next round.

A payout under 0.0001 SOL is not sent. It carries over to the wallet's next round and is sent once the total reaches 0.0001 SOL. The same happens if a wallet's SOL balance is so low that Solana would reject the transfer.

Multiplier ladder

The multiplier depends only on continuous holding time. The clock starts when a wallet first holds at least 50,000 $PAYOUT. It climbs from 1x to 10x at 1 day, and buying more never resets it.

The steps are exact. A wallet that has held for 59 minutes is at 1x, and at 60 minutes it is at 2x from the next round on. Selling or sending out any amount returns the wallet to 1x and restarts the clock.

Vault and forfeits

Each round, 40% of a wallet's cut is credited to its vault. Every credit has its own unlock time, exactly 24 hours after it was made. When a credit unlocks, it is sent automatically in the next round. There is nothing to claim.

If a wallet sells or sends out any amount, every credit in its vault that has not yet unlocked moves to the forfeit pot. The forfeit pot is added to the next round's pot and split among eligible wallets by the same weights as the fees. Credits that had already unlocked are not affected and are sent as usual.

The engine holds vault balances in the treasury wallet. At every round it checks that the wallet holds at least the fee pot, the forfeit pot and all vaults combined, plus a reserve of 0.20 SOL for transaction fees. If it does not, payouts pause until it does, and the status page says so. The live numbers are on the verify page.

Treasury

One wallet does three jobs: it receives the coin's creator fees, it holds the treasury's USDC, and it sends every payout. Its address is 5Ap5RJn9hy5Zj4Vc7RoFocjp5Fwyjty56Rmpcu4uWMSY, and every transaction it makes is public.

The treasury is paid out in phases. Each phase has a fixed budget in dollars. Every round the engine takes that round's share of the budget and adds it to the round pot. The treasury is held in SOL, so each round's dollar amount is valued at the SOL price at that moment and no swap is needed. From there it is treated exactly like creator fees: the same weights, the same instant and vault split, the same forfeits. The current setting is the phase budget paid evenly over 3 hours, which is $16,000 a day spread over the rounds.

When a phase's budget has been paid in full, treasury payouts stop by themselves. Creator fee payouts carry on as before. Nothing more is paid from the treasury until a new phase is started with a new budget, and that is recorded in the changelog. Phase 1 has a budget of $2,000.

Fee money and treasury money sit in the same wallet but are accounted for separately. Every round file states how much of its pot came from fees, how much from the treasury and how much from forfeits, with the swap transaction for the treasury part.

Launchpad

Anyone can launch a coin from here. It is created on pump.fun from the creator's own wallet and trades there like any other coin. At launch, pump.fun fee sharing is set so that 100% of the new coin's creator fees go to the treasury wallet. pump.fun allows that split to be set once only, so it cannot be changed afterwards.

Every round the engine collects the fees of launched coins and adds them to the same pot as $PAYOUT's own fees. They are paid to $PAYOUT holders by the same weights. Each round file states how much of its fees came from launched coins, and every coin is listed on the coins page with what it has paid.

Changes to the rules

The numbers on this page are the rules in force right now. They can be changed, but never in the middle of a round: a change is queued, takes effect at the start of the next round, and is listed in the public changelog with the time, the old value and the new value. Each round file records the rules it was computed with.

Exclusions

These addresses hold $PAYOUT but are never paid, and their balances are left out of the total weight:

• The pump.fun bonding curve.
• The PumpSwap pool, and any other liquidity pool or program-owned account.
• The treasury wallet itself.

Program-owned accounts are recognised by their address type, so a new pool is excluded without anyone adding it to a list. No other addresses are excluded.
