How Appdrop pays app buyers

Where the fees go

pump.fun pays a creator fee on every trade of a coin, on the bonding curve and after it graduates. On Appdrop that fee is split when the coin launches, in pump.fun’s own fee sharing, and the split’s admin is revoked in the same step, so it can never change.

goes to the coin’s payout wallet, which pays it out to the coin’s app buyers. goes to Appdrop’s platform wallet, which spends all of it buying $APPD on the market and burning what it buys. The launcher gets no share.

How a buy is matched to its app

Solana has no field that says which app sent a trade. Both apps leave a public mark on their transactions, and Appdrop reads each buy of a coin for the mark of the coin’s app.

pump.fun app

Every trade from the pump.fun mobile app calls the app’s own program. A buy counts when its transaction calls that program.

FOMO

FOMO’s relayer pays the network fee for every FOMO trade and signs it alongside the user. A buy counts when the relayer co-signed it.

The wallet credited is the one that signed the trade and received the coin. pump.fun’s trade record can name a router instead of you, so Appdrop reads who actually received the tokens. A trade that failed is never counted.

Not counted: buys on the pump.fun website (it sends the same plain instructions a bot does, so there is nothing to tell them apart), buys in other apps, terminals and bots, the launcher’s dev buy, and tokens sent to you from another wallet.

How your share is weighed

Each wallet has an earning balance: the coins it bought in the app, capped at what it still holds. Your share of a payout is your earning balance multiplied by the time you held it, against everyone else’s.

• Buy in the app: your earning balance goes up by what you bought.
• Sell some: it drops to what you still hold, and it does not come back if you later buy somewhere else. Buy in the app again to earn on more.
• Send tokens to another wallet: your earning balance drops with them, and the other wallet earns nothing on them.
• Hold longer: a buy held for the whole time since the last payout weighs twice as much as one made halfway through.
• Sell everything: what you had built up since the last payout goes to the holders who stayed.

The bonding curve, pools, program accounts and Appdrop’s own wallets are never paid.

When payouts go out

Fees are collected into each coin’s payout wallet, and a round runs once the pot is worth sending, at most every few minutes. Payouts go straight to holders’ wallets. There is nothing to claim.

A share too small to be worth a transaction waits, keeping its weight, and is paid in a later round. A wallet holding no SOL at all needs enough to open its account first, and its share waits until it does. Nothing is lost.

The payout wallet is a Privy server wallet made for that coin alone. Appdrop’s server never holds its key; it asks Privy to sign each payout. The payout wallet pays its own network fees out of the fees it collects.

Coins paired with a token

A coin can be paired with any token pump.fun accepts instead of SOL, such as USDC, a tokenized stock or a pump coin. Its creator fees then arrive in that token, and app buyers are paid in it, under the same rules.

Paying in a token needs SOL for network fees and for opening token accounts, which the fees cannot cover. So a token-paired launch puts a little SOL into the coin’s payout wallet, paid by the launcher. A holder without an account for the token gets one opened only when their share is worth it; until then their share waits.

Check it yourself

Each coin’s page links to its payout rounds. The rounds page lists every credited app buy with its transaction, so you can open it and see the app’s program or relayer in it, and every round with the pot, each wallet’s weight, what it was paid and the payout transaction.

The payout wallet

Every collection into it and every payout out of it is a transaction on Solscan.

The burns

Launching a coin

1. Pick the app

   The pump.fun app or FOMO. It is written into the coin’s metadata and cannot change once the coin is live.

2. Pick the pair and fill in the coin

   SOL or another token, then name, ticker, image and your dev buy. A dev buy is required, and it never earns.

3. Sign

   Your own wallet signs. The launch creates the coin on pump.fun, makes your dev buy and locks the fee split. You pay the network costs and the dev buy; nothing else is charged.

What you trust Appdrop for

The split itself is enforced by pump.fun on chain and cannot change. Deciding who is in each round is done by Appdrop’s server from public chain data, under the rules on this page. Every input is published on the coin’s rounds page, so anyone can recompute a round and compare.
