# Buyback and burn

> Fees buy the coin off the market and burn it.

The buyback share of every claim goes into a pot. Once the pot holds at least 0.01 SOL, the engine spends all of it buying the coin and burns exactly the amount it bought. Supply only goes down.

## Where it buys

* **Before graduation**, on the pump.fun bonding curve.
* **After graduation**, on the coin's PumpSwap pool.

The buy and the burn are separate on-chain steps. The engine records the coin balance before and after the buy, and burns the difference, so nothing else the vault holds is touched.

## Vetoed creator cuts

When holders [veto](https://docs.veto.fun/holders/veto.md) a creator payout, the escrowed SOL is moved into this pot and burned the same way. Burned totals on a coin's page include vetoed amounts.

## What you see

On a coin's page, the buyback section shows SOL waiting in the pot, SOL spent so far and the total amount burned. Each burn appears in the activity feed with a link to its transaction.
