Every fee
tops up
the pool.

Every creator fee a coin earns automatically goes back into its own liquidity pool. The protocol converts the fees into the required token and SOL amounts, adds liquidity, and burns the LP tokens. The more it trades, the deeper its pool. No team allocation. No liquidity anyone can pull.

    Launch on the curve

    create_v2 mints a Token-2022 coin on Pump.fun. Its creator is a per-coin engine wallet derived from HMAC(secret, mint), not the launcher.

  2. 02

    Fees accrue

    Every trade pays Pump.fun's creator fee to that engine wallet's vault: lamports on the curve, WSOL on PumpSwap after graduation.

  3. 03

    Claim and rebalance

    The keeper sweeps both vaults, then buys exactly enough of the coin to hold the two sides 50/50 by value at the pool price.

  4. 04

    Deposit and burn

    Both sides go into the coin's canonical PumpSwap pool. The LP tokens are burned in the same transaction, so the depth is permanent.

Launch a coin whose pool only gets deeper.

One wallet approval. Live on Pump.fun in seconds, with every creator fee routed back into its own liquidity.
