The idea in three sentences

Every time someone buys or sells a coin on pump.fun, a small fee is paid to the coin. On a normal coin, the person who made it keeps that fee. On a coin launched here, the fee goes to the people who stake the coin, in SOL, every minute.

If you stake

1. 1Buy a coin, here or on pump.fun.
2. 2Stake it. With a connected wallet: one click (“Buy & stake” does both in one transaction). Without connecting anything: send the coin from your wallet to the coin’s staking address, like sending to a friend (minimum 1,000 coins worth 0.01 SOL, from your own wallet, never from an exchange).
3. 3From the next minute you get your share of every fee, in SOL, sent to your wallet every minute. Your share is your staked coins divided by all staked coins. Nothing to claim; amounts under 0.001 SOL wait until they add up.
4. 4To leave: click Unstake, or send 0.01 SOL to the same staking address from the same wallet. Your coins stop earning at once and are free 1 hour later. The wait is there so nobody can jump in just before a payout and out right after.

If you launch a coin

1. 1Pick a name, a ticker and a picture. There is no fee setting: 100 % of your coin's trading fees go to the people who stake it, on every coin, always.
2. 2You sign the launch. The coin is created on pump.fun like any other, with one difference: its fee split is written once and then locked by pump.fun itself. Nobody can change it afterwards: not you, not us.
3. 3People have a reason to hold your coin instead of flipping it: staking it pays them. Want to earn from your own coin? Stake it, and earn like everyone else.

What it costs

On trades

Nothing from us. pump.fun's usual trading fee applies; the coin's part of it is what stakers receive.

To launch a coin

A flat fee in SOL, shown before you sign (0.2 SOL at most, written in the program), plus pump.fun's and Solana's own costs.

To stake

Nothing. With a wallet you pay a small account rent (about 0.002 SOL) that comes back when your position is closed.

To unstake

A flat fee, 0.01 SOL today (0.05 SOL at most, written in the program).

On payouts

Nothing from us. Each payout carries its share of the network fee of the transaction that sends it (0.000005 SOL at most, split between everyone paid in it).

Those two flat fees are the platform's only income. Part of it is sent to the people who stake $PoS, the platform's own coin, once it is launched. See Transparency for the live numbers.

What you are trusting

• The fee split cannot move. It is locked on pump.fun, by pump.fun's own program. Check it for any coin on the Verify page.
• Your coins only go back to you. The staking address has no private key. The program only returns coins, and only pays SOL, to the wallet that staked them.
• With a wallet, you depend on nobody. Stake, unstake, withdraw and claim are transactions you sign; they work even if our service is down.
• Without a wallet, one step is ours. The chain does not tell the program who sent a transfer, so our service reads the sender and tells it. The program never credits more than the pool received and publishes every credit with its transaction. If our service stops, transfers wait to be credited; nothing is lost.
• The program can still be upgraded by the key that deployed it, until that key is given to a multisig or renounced. This page says when that changes.
• The coins themselves are memecoins. Their price can go to zero. Staked coins cannot be sold during the 1-hour wait. A pool where one wallet holds most of the stake pays mostly that wallet: the coin's page shows it.

A coin's staking address: recompute it yourself. The wallet that receives the platform's fees is on the Transparency page.

The exact rules

Window

1 minute, aligned to the clock. Fees received during a window are split at its close between the coins that were staked for the whole window.

Start earning

From the window after the one you staked in.

Leaving delay

1 hour; nothing is earned meanwhile.

Smallest transfer credited

1,000 coins worth at least 0.01 SOL (no minimum when you stake with a wallet).

Exit by transfer

At least 0.01 SOL to the staking address, from the wallet that staked. The exit fee goes to the platform; anything above it stays in the pool.

Smallest payout pushed

0.001 SOL; below that it accumulates. You can always claim it yourself with a wallet.

Fee split

100 % to the coin's pool of stakers, on every coin. The program refuses any other split, and pump.fun locks it once written.

After graduation

Nothing changes for stakers: the fees of PumpSwap trades are collected the same way and split the same way.

Empty positions

Closed once your coins are back: what is still owed is paid to you in full, the account's rent returns to whoever paid it, your lifetime payouts stay on your wallet page.
