⚠️ DEPRECATED: do not use⚠️ This version was superseded by
ProtocolFeeHelperV2, which generalizes the implementation to allow multiple, transferrable allowlists. This allows multiple partners to use the same contract, and eases the burden on governance.
The Protocol Fee Helper contract enables granular control over the power to set protocol swap and yield fees on pools. It maintains a set of registered pools whose fees can be set by authorized accounts. Governance must first grant this contract permission to set protocol fees, then add a set of pools, and finally grant permission to call the fee setters on the helper contract.
