# Events & Monitoring

* `WarpFactory.PairCreated(token0, token1, pair, pairIndex)` – emitted once per pool.
* `WarpPair.Mint(sender, amount0, amount1)` – a new liquidity provision.
* `WarpPair.Burn(sender, amount0, amount1, to)` – liquidity withdrawn.
* `WarpPair.Swap(sender, amount0In, amount1In, amount0Out, amount1Out, to)` – emitted on every hop in router swaps.
* `WarpPair.Sync(reserve0, reserve1)` – reserves updated; ingest for analytics/TWAPs.
* ERC-20 `Transfer` on LP tokens – track LP ownership changes.
* Router does not emit custom events; rely on pair-level emissions and transaction logs.
