How it works

A pump.fun coin tied to one host: any Solana coin, chosen at launch and fixed forever. Every minute, the coin’s creator fees are claimed and spent buying the host on the open market, and every token bought is burned. Nobody presses anything, and nobody keeps anything.

Launching

  1. Pick what it burns. Paste a host’s contract address, and choose how much of the burn goes to your own coin instead (0 to 100%). Or skip the host and make a coin that only burns itself. SOL and stablecoins can’t be hosts, and a host needs at least $5,000 of liquidity so it can be bought every minute.
  2. Name it and approve once. One transaction creates the coin on pump.fun, with your wallet as creator, and locks 100% of its creator fees to Symbio’s burn wallet through pump.fun’s fee sharing, with admin revoked. From that moment nobody, us included, can point the fees anywhere else. A dev buy doesn’t fit in the same transaction, so it adds a second approval for the lock.
  3. Its address ends in SYM. Every coin launched here gets a contract address ending in SYM, so a Symbio coin is recognisable on sight.

Where every fee goes

  • 90% is the burn: split between the host and the coin itself by the share set at launch.
  • 10% buys $SYMBIO, the platform token, and burns it.
  • 0% goes to the launcher, and 0% to us beyond $SYMBIO’s tenth.

Buys go through Jupiter from the treasury wallet. A buy is capped at a small slice of the target’s liquidity so it can’t move a thin market; what the cap holds back waits for the next minute. Fees below the minimum buy (0.02 SOL) wait until they add up. Every burn gets a numbered receipt with its buy and burn transactions.

$SYMBIO, the main boiler

$SYMBIO’s own creator fees run a different engine. Every hour it reads every $SYMBIO holder’s wallet, finds the coins at least 5 holders share, weights each by how much $SYMBIO those holders hold, and buys the top ones for a separate wallet that keeps them. Hold $SYMBIO and the coins you hold get bought. See what it’s feeding.

Coins launched on pump.fun directly

  1. Set the coin’s website to its host’s page here.

    https://usesymbio.fun/h/host address. Add ?self=25 to send 25% of the burn to the coin itself. Leave the website off to burn only the coin. pump.fun doesn’t let the website change later.

  2. Share the creator fees to Symbio’s burn wallet.

    In the coin’s creator settings, turn on fee sharing and add it as a recipient. Any share works; the coin’s page shows which.

  3. Save the fee split. It can’t be changed after.

    Until it’s saved, with admin revoked, the coin isn’t listed. After that it appears within a few minutes, or paste its address below to list it now.

What to check

  • The coin’s page shows its fee lock. The lock is on-chain: pump.fun’s sharing config for the coin names the treasury and has admin revoked.
  • The treasury is ATh3ZtZYgURkgSeqbeudmvjfo2WPTyTWabrNXattqR3s. Every claim, buy and burn it makes is public.
  • If the engine stops, the header says so. Fees wait in each coin’s vault on pump.fun and burn when it restarts.
