# Fee Architecture

Reference for Doppler fee collection, distribution, and configuration.

---

Overview

Doppler implements a multi-layer fee system:

LP Fees: Trading fees collected during swaps (configurable per pool)
Protocol Fees: Whetstone's cut from LP fees (5% of fees or 0.1% of proceeds)
Integrator Fees: Front-end integrator's share (remainder of LP fees)
Beneficiary Fees: Distribution to locked pool beneficiaries

Fee Modes

| Mode | Description | Pool Type |

|------|-------------|-----------|

| Standard | Fixed fee set at pool creation | V3 pools, V4 without hook |

| Dynamic | Hook can modify fee per swap | V4 with Doppler hook |

Key Contracts

| Contract | Purpose | Source |

|----------|---------|--------|

| Airlock | Protocol/integrator fee handling | src/Airlock.sol |

| FeesManager | Beneficiary fee tracking | src/base/FeesManager.sol |

| StreamableFeesLocker | Position-based fee streaming (V1) | src/StreamableFeesLocker.sol |

| StreamableFeesLockerV2 | Pool-based fee streaming (V2) | src/StreamableFeesLockerV2.sol |

---

Common Tasks

Check protocol fees

```solidity

uint256 fees = airlock.getProtocolFees(tokenAddress);

```

Check integrator fees

```solidity

uint256 fees = airlock.getIntegratorFees(integratorAddress, tokenAddress);

```

Collect beneficiary fees

```solidity

// For FeesManager-based contracts

feesManager.collectFees(poolId);

```
