Pool Events

In the context of automated market maker (AMM) pools, liquidity pool events refer to adding or removing liquidity from the pool.

mint and burn are pool events that involve the creation or destruction of LP tokens. LP tokens are first minted and issued when adding liquidity to a pool. In the same way, a burn event refers to withdrawing tokens from the pool in exchange for destroying the previously issued user's LP tokens. These events are often used to adjust the supply of tokens in the pool and to maintain a healthy liquidity balance.

You can read more about pools in the Pools section.

Pool Event Methodology

The methodology is similar to swaps: We listen to all pool transactions which include a signature of burn or mint on the supported networks.
