Onchain events

Emitted once per coin, in the launch transaction.

event Launched(
  address indexed token,
  address indexed creator,
  address pool,
  uint256 tokenId,
  string name,
  string symbol,
  string persona,
  string imageCid
);

The picture and the character description are on chain, which is why they survive independently of any database.

Emitted whenever anyone collects a coin's fees.

event FeesCollected(
  address indexed token,
  uint256 wethCollected,
  uint256 tokenCollected,
  uint256 at
);

at is the block timestamp of the collection. All four parameters are part of the event signature, so subscribe to FeesCollected(address,uint256,uint256,uint256): a three-parameter signature hashes to a different topic and never matches.

Trades are ordinary Uniswap V3 Swap events on the coin's pool:

Swap(address indexed sender, address indexed recipient,
     int256 amount0, int256 amount1,
     uint160 sqrtPriceX96, uint128 liquidity, int24 tick)

Use recipient, not sender, to attribute a trade. A launch dev buy is sent by the factory on the creator's behalf, so sender names the factory every time.
