# BMX Classic Total value locked Methodology

## 1. Overview

Total value locked measures the total value of assets deposited into BMX Classic vault contracts. This metric serves as a primary indicator of the liquidity available for trading and the overall scale of the product's collateral base. Values are calculated based on the market value of all supported assets held within the protocol's smart contracts on Base.

## 2. Data sources

- **Blockchain events**: ERC-20 token transfers and native token transfers involving BMX Classic vault contracts on Base
- **External data**: End-of-day price feeds for assets held in the vault

## 3. Step-by-step calculation

### Component A: BMX Classic vault flow tracking

- **Purpose**: Identify all incoming and outgoing asset movements for BMX Classic
- **Logic**: ERC-20 token transfers and native token transfers are filtered for the BMX Classic vault address on Base. All incoming and outgoing movements are captured to determine the net change in asset quantities for the specified account. Assets are identified using metadata and decimal precision is applied to normalize all quantities.
- **Key fields**: `amount`, `timestamp`, `token_address`

### Component B: Balance calculation and USD conversion

- **Purpose**: Determine the daily standing balance of each asset in USD
- **Logic**: Daily net flows are aggregated and a cumulative sum is applied to determine the total quantity of each asset held in the vault at the end of each day. These quantities are multiplied by end-of-day price feeds to determine the USD value of each position. A fill-forward strategy is utilized to maintain balance data for days where no transfer activity occurs.
- **Key fields**: `amount`, `price_usd`, `timestamp`

### Component C: Final aggregation

- **Purpose**: Consolidate values into the final metric
- **Logic**: The USD values of all individual asset balances are summed to calculate the total value locked for BMX Classic. The final values are grouped by day and chain, ensuring all deposits are accounted for in the aggregate metric.
- **Key fields**: `tvl`, `timestamp`, `chain_id`
