Add Fee Mechanism and Distribution
Goal
Implement a flexible fee system for token swaps that accumulates fees and distributes them to liquidity providers or a designated treasury, with administrative controls for fee parameters.
Implementation Details
1. Configurable Fee Structure
- Implement a fee model (e.g., percentage of swap amount) that can be applied to each token swap.
- The fee rate should be configurable by authorized administrators.
- Ensure fees are deducted correctly from the input or output amounts during swaps.
2. Fee Tracking and Accumulation
- Track accumulated fees securely within the contract.
- Separate fee balances for each token or unified accounting based on design.
- Ensure fee accrual does not interfere with pool balances used in swaps.
3. Fee Distribution
- Distribute accumulated fees periodically or on-demand to:
- Liquidity providers (proportional to their shares).
- Or a designated treasury address.
- Implement functions to claim or transfer fees to beneficiaries.
4. Administrative Fee Parameter Management
- Provide administrative functions to:
- Modify fee rates.
- Change fee recipients (e.g., treasury address).
- Enable/disable fee mechanism if needed.
- Protect these functions with access control (e.g.,
onlyOwner or role-based access).
5. Event Emissions
- Emit events for changes in fee parameters and when fees are collected or distributed.
Example event signatures:
event FeeParametersUpdated(
uint256 newFeeRate,
address newFeeRecipient
);
event FeesCollected(
address indexed token,
uint256 amount,
address indexed recipient
);
