Your coin is created on the pump.fun curve with a vault set as its creator. From the first trade, its fees are claimed by an agent, deployed as liquidity, and the fees that liquidity earns are spent buying your coin back.
Bought in the same transaction that creates the coin, at the curve's opening price. Leave empty to launch without one.
Not a single pool balance. The agent spreads your coin's fees across a range of price bins on Meteora, one bucket per price, so the liquidity earns wherever the market actually trades. Each bucket collects fees separately, which is what lets every earned lamport be measured and spent on buying your coin back.
You pay the network fee, 0.02 SOL of gas for your coin's vault, and your initial buy.
