A Clanker v5 token can burn part of its trading tax. The creator chooses the burn share at launch, as a percentage of the tax after the Clanker fee.

​
How it works

  1. A trade pays the buy or sell tax. Clanker takes its fee first (see Creator Rewards & Fees).
  2. The burn share of the remaining tax is taken in the token itself, not in the pair token. On a buy, it comes off the tokens the buyer receives.
  3. The tokens are added to the token’s Pending Burn, held in the FeeEscrow for the dead address (0x000000000000000000000000000000000000dEaD).
  4. Any wallet can send the pending burn to the dead address. Once sent, those tokens are out of circulation for good.

​
Example

A token has a 5% tax and a 20% burn share. Someone buys for 1,000 USDC. Because this trade is a buy, the burn share comes off the tokens the buyer receives: about 9 USDC worth of tokens goes to the pending burn.

Burn on clanker.world

The token page shows a Burn card with:
  • Pending Burn: tokens from trades that are waiting to be burned.
  • Total Burned: the balance of the dead address. It also counts any other transfers to that address.
Connect any wallet and select Burn now to send the pending burn to the dead address.

With the API

The token fee history (GET /api/tokens/{address}/fees) gives the burn share of each trade and the executed burns, in the token. See Fees.
