BribeCollectorV1_3

Git Source

Inherits: InfraredUpgradeable, IBribeCollector

The Bribe Collector contract is responsible for collecting bribes from Berachain rewards vaults and auctioning them for a Payout token which then is distributed among Infrared validators.

This contract is forked from Berachain POL which is forked from Uniswap V3 Factory Owner contract. https://github.com/uniswapfoundation/UniStaker/blob/main/src/V3FactoryOwner.sol

v1.3 adds a permission check to require KEEPER_ROLE for claiming fees. This is necessary because Infrared now boosts external validators and collects POL incentives from them. Since Merkle proofs for these incentives are only updated periodically, this can lead to unpredictable value inflow. If timed unfortunately, this could create a significant loss for the protocol if the value far exceeds the payout amount. The onlyKeeper modifier is a temporary security measure until a smoothing mechanism for available tokens to claim is implemented.

uint256 public payoutAmount;

__gap

uint256[40] private __gap;

) external onlyKeeper;
