Introduction

#What it does

Every trade on a pump.fun coin pays a creator fee. Normally it goes to whoever launched the coin. On Symbio, the fee is locked on-chain at launch to a burn wallet, and every minute it’s spent buying a coin and burning the tokens bought.

When you launch, you pick what your coin burns:

• A host: any other Solana coin with a market.
• Its holders’ coins: the coins your coin’s top 100 holders hold most, up to 10, re-read every five minutes.
• Itself: a buyback and burn of your own coin.

You can also split the burn between your own coin and either of the first two.

#The flow, in one minute

1. People trade your coin on pump.fun. Each trade adds to its creator fees.
2. Every minute, the fees are claimed to the burn wallet.
3. 90% buys what your coin burns; 10% buys $SYMBIO.
4. Everything bought is burned in the same minute, and the burn gets a numbered receipt with its transactions.

Nobody presses a button, and nobody keeps the fees: not the launcher, not us.
