How burns work

What a coin can burn

90% of every fee is the burn. At launch you decide what it buys, and that choice is fixed for the life of the coin.

A host coin

Any Solana coin with a market: a pump.fun coin, a graduated one, or any other token that trades. Paste its address when you launch. Every minute, your coin’s fees buy it on the market and burn what they bought, so the host’s supply only shrinks.

Several coins can share a host. Each host has its own page (linked from every coin that burns it) showing every coin feeding it and the total burned.

Its holders’ coins

Instead of one host, the burn follows your holders: up to 10 coins your coin’s top 100 holders hold most, re-read every five minutes. How the picks are made.

Only itself

The whole burn buys your own coin and burns it: a buyback on every trade.

The self-burn share

With a host or holders’ coins, you can send part of the burn to your own coin instead, from 0 to 100% for a host and up to 90% for holders’ coins. For example, with a 25% self-burn share on a host:

  • 67.5% of every fee buys and burns the host.
  • 22.5% buys and burns your coin.
  • 10% buys and burns $SYMBIO, as always.

What can’t be burned

  • SOL and wrapped SOL, and SOL staking tokens.
  • Stablecoins (USDC, USDT, PYUSD and the like), wrapped majors (BTC, ETH) and tokenized stocks.
  • A coin with no market to buy on.
There’s no liquidity minimum for a host. A thin market is bought in small pieces, a minute apart, so a single buy never moves it much. See the burn engine.
