GIP-0002: Separate destination address for Indexer indexing rewards

GIP-0002 describes a mechanism for Indexers to withdraw rewards to a designated address instead of automatically re-staking these rewards in the protocol. The effect is that Indexers that interact with the protocol via the widely used TokenLock vesting contracts will be able to withdraw indexing rewards to cover operational costs, without fully unstaking from the protocol.
