Events to index

Start from the factory's TokenLaunched: it describes a launch in full, so describing a token never needs the factory's state. Trades are the pool manager's own Swap events. The hook's FeeAccrued comes once per swap, even when the fee rounds to zero, so it pairs with Swap one-to-one.

Read from the factory proxy's deployment block: nothing of the launchpad's comes before it. Read the whole of each launch's transaction, not from TokenLaunched on: the creator's first buy, its FeeAccrued and Swap among them, is logged before it. Every ABI to decode them with is at /docs/abis/events.json (Build on Montra).

The owned contracts also emit OpenZeppelin's ownership events, the factory its proxy's Upgraded, and every token the ERC-20 Transfer and Approval, and OpenZeppelin's Initialized once, as the launch sets it up.

A v4 Swap shows the pool's side of a trade, and the hook's fee is outside it. Its amounts are signed as the swapper sees them, negative paid into the pool and positive paid out. On a buy, the pool sees what is left of the input once the hook has taken its fee; on a sell, the pool pays out the whole and the hook takes its fee from that. So a trader's own amounts are the Swap's quote amount plus FeeAccrued.fee on a buy and less it on a sell; the token amounts are exact either way. Montra's router reports a trader's amounts directly (Swapped), but a trade through any other router has only the two.

FeeAccrued comes before its Swap when the quote is the amount named (an exact-input buy, an exact-output sell) and after it otherwise: pair them by transaction, pool and zeroForOne, in order. Its amountSpecified is signed as v4 signs it, negative for exact input and positive for exact output. Swap.fee is v4's own swap fee, the LP fee (zero until the LP line) and Uniswap's protocol fee should that ever be switched on: never show it as the pool's fee.

A buy inside its pool's anti-snipe window pays a higher rate, and the same sum holds: its FeeAccrued.fee is that rate's fee, so the trader paid the Swap's quote amount plus it. protocolPart stays the protocol's own pips of the leg; the rest, the premium included, is the creator side's. The Swap itself never shows the premium, so a chart built from Swap events draws the pool's price, not what buyers paid. The window starts at the block time of the launch's PoolRegistered, which carries its start and length (The anti-snipe fee).
