PoolTogether Token Listener Interface
The token listener interface allows contracts to 'listen' to token mints, transfers, and burns from some contracts. The PoolTogether V3 Prize Pool expects it's Prize Strategy to implement the Token Listener Interface. The PoolTogether V3 "Multiple Winners" Prize Strategy can also have a Token Listener attached to it; effectively chaining callbacks from the prize pool to the prize strategy.
Token Listener Interface
The Token Listener Interface is defined in the ITokenListener.sol file. It inherits from the IERC165 so that it supports on-chain reflection. ERC165 support is required by some consumers of token listeners, such as the core PoolTogether V3 prize pool and the Multiple Winners prize strategy.
Usage
You can depend on this package via NPM if you like:
