# Launch on pump.fun

> A coin on pump.fun's own curve, with its creator fees wired into a strategy from the first trade.

The coin is created on pump.fun with its on-chain creator set to the coin's PURPS wallet, so creator fees flow to the strategy from the start. Two signed transactions, then a registration. The complete example on the purps.lol page applies here with the paths changed.

<Steps>
  <Step title="Read the options">
    `GET /launch-options` and look under `venues.pumpfun`: who may launch, who may use a custom pair, and the payout assets. Pairs are under `pumpfun` in `GET /pairs`.
  </Step>

  <Step title="Prepare">
    `POST /pumpfun/prepare` with `name`, `symbol`, `creatorWallet`, and optionally `quoteMint` (from `pumpfun` in `/pairs`; SOL when omitted) and `devBuySol`. Sign `message`.
  </Step>

  <Step title="Submit">
    `POST /pumpfun/submit` with the same terms, the logo, socials, `ts` and `signature`. Sign the returned `transactions` (the one at `createIndex` with the mint key too) and send them through `/transactions/send`, one at a time, waiting for each to confirm.
  </Step>

  <Step title="Lock the fee routing">
    Once the create has confirmed: `POST /pumpfun/fees` with `mint` and `creatorWallet`. Sign and send the returned `transaction` the same way. This is pump.fun's fee-sharing config: once set, the coin's creator fees go to its PURPS wallet permanently. `done: true` means it was already set.
  </Step>

  <Step title="Register the strategy">
    `POST /redirects` with `mint` and your strategy `config`, built as on the purps.lol page. No signature needed: the fee routing you just locked on chain is the proof. If it answers `registered: false`, the chain has not shown us the routing yet: wait a few seconds and call it again. `registered: true` and the coin is live on purps.lol with its strategy running.
  </Step>
</Steps>

The creator wallet needs about 0.04 SOL plus the dev buy (0.045 with a custom pair).
