Creator fees, by post
Launch a coin.
Post its fees
to any inbox.
Every trade on your pump.fun coin pays a creator fee. Here, those fees are posted to an email address. Whoever owns it signs in, and the money is already waiting.

§ 02 · Route
How a fee travels.
No claims to remember, no keys to hand over. The coin pays a vault; the vault pays the inbox.
- A
Someone trades
Every buy and sell on pump.fun (and PumpSwap after graduation) pays a creator fee.
- B
The vault collects
The coin's creator is a vault opened just for it. Nobody can redirect those fees, the launcher included.
- C
Sorted & stamped
Every 30 min, vaults over 0.02 SOL are swept. 10% postage comes off.
- D
Delivered
It lands in the wallet tied to the email. They sign in with a one-time code and can withdraw anywhere.

01Does the payee need a crypto wallet?
No. A Solana wallet is opened for their email when the coin launches. They sign in with a one-time code sent to that email and the balance is already there. They can withdraw anywhere or export the key to Phantom.
02Can the launcher change who gets paid later?
No. The payee is fixed when the coin is posted, and the coin's creator on pump.fun is a vault that only pays that email. Not even the launcher can redirect it.
03What does it cost?
Launching costs what pump.fun charges, plus any first buy you choose. After that, 10% of each delivery is kept as postage. We pay the network fees for collecting and delivering.
04How often are fees delivered?
Every 30 minutes, any vault holding at least 0.02 SOL in fees is swept and delivered. Smaller amounts wait until they cross the line, so network costs never eat the delivery.
05Who holds the keys?
Each coin's vault key is held by postage, encrypted, and only ever used to collect fees and pay them to the payee. The payee's wallet belongs to them: we can't move money out of it.
06How do I know it's real?
Every ledger entry is checked on-chain before it's listed: the launch transaction, the pump.fun creator (its vault) and our memo. Each delivery links to its Solana transaction.
