A coin can use part of its own fees to buy itself back on the market and burn the tokens it bought. Burned tokens are gone forever, so the supply only goes down. Everything runs automatically from the coin’s own burn vault, and every buy and burn is shown on the coin page with its transaction.
How a coin gets buyback & burn#
- By choice: the creator picks a buyback & burn share in the fee split at launch, for example with the Deflationary preset.
- Not on AI coins: their fixed split has no buyback & burn share, and the AI's 30% is used only for the AI, never for buybacks or burns. See AI vault & billing.
How it runs#
Fees fill the burn vault
Each fee distribution sends the burn share to the coin’s burn vault. On coins that trade against another token, the vault’s tokens are sold for SOL first.Size the buy
About every hour, the worker looks at the vault’s SOL, keeps 0.01 SOL for fees, and caps the buy at 5 SOL. If the buy would move the price by more than 5%, it halves the amount, up to four times.Buy back
The vault buys the coin on its bonding curve or, after graduation, in its DEX pool, with a tight 1.5% slippage limit. The buy is simulated first and pays no site trade fee.Burn
Every token the vault bought is burned in a separate transaction. Tokens left over from an interrupted run are burned at the start of the next one.
Limits#
| Rule | Default |
|---|---|
| How often | About every hour |
| Smallest buy | 0.05 SOL; below that the vault waits |
| Largest buy per run | 5 SOL |
| Slippage limit | 1.5% |
| Largest price impact | 5% (the buy is halved until it fits) |
| Kept in the vault | 0.01 SOL for fees and rent |
The platform can change these defaults. The tight slippage is deliberate: the vault buys on a schedule from a public address, and a wide slippage would make it an easy target for sandwich bots.
Note
Meteora coins#
On Meteora coins, the burn share is first collected in the coin’s fee wallet, sold for SOL and passed to the burn vault, about every 15 minutes. The buyback then runs as above. After graduation, the coin side of the fee wallet’s pool fees is also burned.
What it does and does not do#
- It permanently reduces the coin’s supply.
- It only spends money that the coin’s own fees put in its burn vault.
- It does not promise any price. A buyback is a normal market buy and the price can still fall.
