# Uniswap Labs Supply-side fees Methodology

## 1. Overview

Supply-side fees represent the portion of protocol fees that are distributed to liquidity providers. For Uniswap Labs, this metric is consistently zero because the protocol retains all collected interface fees rather than sharing them with liquidity providers. The calculation builds upon the total fees collected by Uniswap Labs across their various products (UniswapX and Universal Router) but sets the supply-side allocation to 0%.

## 2. Data sources

- **UniswapX events**: Parsed `Fill` events from the `UniswapXDutchOrderReactor` contract on Ethereum
- **Token transfer events**: Token transfer logs from Ethereum, Arbitrum, Avalanche, Base, BSC, Polygon, and Optimism networks
- **Transaction data**: Transaction records from all supported chains to identify user addresses and transaction context
- **External data**: End-of-day token price feeds for USD conversion and token metadata for decimal correction

## 3. Step-by-step calculation

### Component A: UniswapX dutch auction fees
- **Purpose**: Captures fees collected from UniswapX dutch auction order fills on Ethereum
- **Logic**: Identifies UniswapX `Fill` events from the dutch order reactor contract, then finds all token transfers within those same transactions that are sent to specific Uniswap Labs collector addresses. Only includes transactions from July 1, 2023 onwards. The user address is extracted from the `swapper` field in the Fill event, while fee amounts come from token transfers to collector addresses `0x37a8f295612602f2774d331e562be9e61b83a327` and `0x6460d14dbaeb27aefec8ebef85db35defa31c3b9`
- **Key fields**: `block_timestamp` for daily aggregation, `transaction_hash` for linking events, `user_address` from the swapper field, `token_address` and `amount` from transfers to collectors

### Component B: Universal router swap fees  
- **Purpose**: Captures interface fees collected from universal router swaps across multiple chains
- **Logic**: Identifies token transfers where the sender is a known universal router contract address and the recipient is a known Uniswap Labs collector address. Covers seven chains (Ethereum, Arbitrum, Avalanche, Base, BSC, Polygon, Optimism) with chain-specific router and collector addresses. Only includes fees collected between July 1, 2023 and December 25, 2025, when interface fees were eliminated due to the UNIfication proposal. Each chain has multiple router addresses (3-5 per chain) and collector addresses (3-5 per chain)
- **Key fields**: `block_timestamp` for time boundaries, `from_address` (router) and `to_address` (collector) for fee identification, `token_address` and `value` for fee amounts, `user_address` from transaction sender

### Component C: Fee consolidation and filtering
- **Purpose**: Combines all fee sources and applies data quality filters
- **Logic**: Unions the UniswapX and universal router fee data, then excludes transactions involving denylisted tokens including `0x63b420fb3294ba1d300ce5d3ba4bbca0f4fe5e3b`, `0xe4351fc54b6100d3f1741f321a959d45d69c23b1` (DOGEVERSE), and `0xa5be544049f2b4a9db97cf8852c8c99fca30ea2b` (TRUMP token). Each fee record includes business classification fields set to Exchange AMM, exchanges market sector, and DEX business segment
- **Key fields**: All fields from previous components plus business classification metadata

### Final aggregation
- **Combining components**: All filtered fee data is aggregated by day using timestamp truncation to daily boundaries, grouped by chain, token address, and business classifications
- **Currency conversion**: Token amounts are converted to USD using end-of-day price feeds, with automatic decimal correction applied based on token metadata to ensure proper unit conversion
- **Time aggregation**: Daily timestamp boundaries are created by truncating `block_timestamp` to day level, with all fees from the same day grouped together
- **Final calculation**: The supply-side allocation is set to exactly 0 for all records, meaning 100% of collected fees are retained as protocol fees rather than being distributed to liquidity providers. The output includes the same timestamp, chain, and business classification structure as total fees, but with `fees_supply_side` set to 0
