# o1 exchange Fees Methodology

## 1. Overview

Fees measures the total value paid by users to trade through o1 exchange, a DEX aggregator operating on Base. O1 exchange routes trades through Uniswap V4 and 0x Protocol, collecting a 1% fee per trade. These fees flow into two designated fee vault contracts and represent the economic value generated from trade facilitation services. Fees are collected in both ERC-20 tokens and native ETH, then converted to USD for reporting.

## 2. Data sources

- **Blockchain data**: ERC-20 token transfers to fee vault addresses and native ETH flows to fee vault addresses on Base
- **External data**: End-of-day price feeds for collected assets, asset metadata for decimal normalization

## 3. Step-by-step calculation

### Component A: ERC-20 fee collection

- **Purpose**: Capture fees paid in ERC-20 tokens to o1 exchange fee vaults
- **Logic**: ERC-20 token transfers are parsed where the recipient address matches either of two fee vault contracts (0xc98218df72975ee1472919d2685e5bd215baaad4 or 0x1e493e7cf969fd7607a8ace7198f6c02e5ef85a4). Transfers are excluded if the sender address matches either fee vault address to prevent double-counting of internal vault movements. Each transfer's token address and amount are extracted for aggregation.
- **Key fields**: `to_address` (fee vault identification), `from_address` (trader identification), `token_address` (asset identification), `value` (fee quantity)

### Component B: Native ETH fee collection

- **Purpose**: Capture fees paid in native ETH to o1 exchange fee vaults
- **Logic**: Native ETH flows are parsed where the recipient account matches either fee vault address and the transfer value is positive. ETH amounts are represented using the wrapped ETH token address for unified processing with ERC-20 fees.
- **Key fields**: `account_address` (fee vault identification), `value` (fee quantity in native ETH)

### Component C: USD conversion and aggregation

- **Purpose**: Normalize fee values across different assets for reporting
- **Logic**: ERC-20 and native ETH fees are combined and aggregated to daily granularity with UTC day boundaries. Amounts are normalized by decimal precision using asset metadata, then multiplied by end-of-day asset prices to convert to USD. Missing days are zero-filled to ensure continuous time series coverage.
