# Manage a coin

> Attach a strategy to a coin launched without one.

Signed by the launch's creator wallet, the same prepare-sign-submit way.

## Attach a strategy later

A purps.lol coin launched with the `airdrop` or `split` preset can have a strategy attached afterwards. `POST /coins/{mint}/strategy/prepare` with `config`, sign, then `POST /coins/{mint}/strategy/submit` with the identical `config`, `ts` and `signature`.

A `creator`-preset launch cannot: its fee vault is owned by your wallet on chain and the strategy could never claim from it.
