Buyback and burn - Veto

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 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.
