# o1 exchange Trading volume Methodology

## 1. Overview

Trading volume measures the total value of trades executed through o1 exchange, a decentralized exchange aggregator on Base. O1 exchange routes trades through Uniswap V4 and 0x Protocol while collecting a 1% fee per trade. Trading volume is derived from collected fees by applying the inverse of the fee rate, converting fee amounts to the underlying trade values they represent.

## 2. Data sources

- **Blockchain events**: ERC-20 `Transfer` events to two fee vault contracts (0xc98218df72975ee1472919d2685e5bd215baaad4 and 0x1e493e7cf969fd7607a8ace7198f6c02e5ef85a4), and native ETH flows to the same vault addresses, covering Base
- **External data**: End-of-day price feeds and decimal precision metadata for traded assets

## 3. Step-by-step calculation

### Component A: Fee collection tracking

- **Purpose**: Capture all fees paid to o1 exchange from user trades
- **Logic**: ERC-20 fees are identified from token transfer events where the recipient address matches either fee vault contract and the sender is not one of the vaults (excluding internal vault transfers). Native ETH fees are tracked from positive-value native flows into the vault addresses. Both fee types use WETH as the token address for native ETH flows.
- **Key fields**: `value` (fee amount), `token_address` (asset identification), `from_address` (trader identification for ERC-20 transfers)

### Component B: Volume derivation

- **Purpose**: Calculate underlying trade volume from collected fees
- **Logic**: Since o1 exchange charges a 1% fee per trade, trading volume is calculated as `fees * 100`. This inverse calculation recovers the original trade value that generated each fee payment.

### Component C: USD conversion and aggregation

- **Purpose**: Normalize values to USD for cross-asset comparison
- **Logic**: Amounts are normalized by decimal precision and multiplied by end-of-day asset prices. Values are aggregated by day, chain, and product dimensions. Daily granularity with UTC day boundaries.
