Buyback + burn

Optional. When enabled, that share of creator fees goes to a vault that can purchase this coin and burn the acquired balance.

This is not a percentage of supply, a token lock, or a price guarantee.

Who holds the money

Nobody. The burn vault is an address derived from the coin's own mint, with no private key in existence, registered directly with pump.fun as a fee recipient. The share is paid into that address by pump.fun; it never passes through Give.

The program has one instruction that can spend it, and deliberately no withdraw instruction. There is no operator setting or emergency path that moves those funds anywhere except into buying the coin and destroying it.

Each coin has its own burn vault. Balances are never pooled.

From fees to a burn

1. Trades generate creator fees.
2. A distribution sends the burn share to the coin's burn vault.
3. An executor quotes a purchase using the vault's balance.
4. The program signs for its vault, buys, and burns the received tokens in one transaction.

If the purchase or the burn fails, the transaction rolls back.

Thresholds

The vault needs at least 0.002 SOL above rent before a buyback can run. Small allocations accumulate; there is no promise of a burn on every trade.

Verifying a burn

Check the transaction: the input mint is this coin, the buyer is its burn vault, the transaction includes both the purchase and the burn, and supply decreased by the burned amount. A transfer to an unfamiliar wallet is not a burn.

Can it be switched off later?

No. Choose before launching.
