# Stargate Fees Methodology

## 1. Overview

The total value paid by users to execute cross-chain asset transfers and swaps through Stargate is measured by Fees. Liquidity provider fees, which compensate users for providing capital to the protocol, and protocol fees, which represent the portion of transaction costs retained for the protocol, are included in this metric. Fees are captured across both Stargate V1 and Stargate V2 architectures and are converted to USD for standardized reporting.

## 2. Data sources

- **Blockchain events**: `Swap` events from `Pool` contracts for Stargate V1, and state-based fee accrual records for Stargate V2, covering Ethereum, Arbitrum, Base, Polygon, and 18 other chains
- **External data**: End-of-day price feeds and asset metadata

## 3. Step-by-step calculation

### Component A: Stargate V1 fee extraction

- **Purpose**: Liquidity provider and protocol fees generated by Stargate V1 trading pools are captured.
- **Logic**: `Swap` events are parsed from `Pool` contracts across all supported chains. Liquidity provider fees and protocol fees are extracted from the event logs. These values are associated with specific assets using pool metadata from `createPool` function calls from `Factory` contracts and historical legacy pool registrations. Amounts are normalized by the decimal precision of the underlying asset.
- **Key fields**: `lp_fee_amount` (liquidity provider share), `protocol_fee_amount` (protocol share), `token_address` (asset identification)

### Component B: Stargate V2 fee extraction

- **Purpose**: Fee accumulation within the Stargate V2 architecture is captured.
- **Logic**: Cumulative fee accrual data is retrieved from state snapshots for Stargate V2 pools. Daily fee totals are calculated by determining the delta between the current day's cumulative accrual and the previous day's value. Pool addresses are mapped to their underlying assets using pool information state records, and gas-related tokens are correctly identified for native asset pools.
- **Key fields**: `fee_accrual` (cumulative totals), `pool_address` (pool identification), `underlying_token_address` (asset identification)

### Component C: USD conversion and aggregation

- **Purpose**: Fee data is normalized into a single currency for cross-chain and cross-asset comparison.
- **Logic**: Fees from Stargate V1 and Stargate V2 are aggregated by day, chain, and asset. These normalized amounts are multiplied by the respective end-of-day USD price feeds for the underlying assets. Total daily values are calculated using UTC day boundaries, and any missing periods are filled with zero values to ensure a continuous time series.
- **Key fields**: `timestamp` (daily granularity), `fees` (summed value), `price_usd` (valuation)
