# Robinhood Chain Bridge Deposits Methodology

## 1. Overview

Bridge Deposits is defined as the total value of assets escrowed in Ethereum Layer 1 bridge contracts for Robinhood Chain. The total value locked (TVL) bridged from Ethereum to the Robinhood Chain Orbit Layer 2 is represented by this metric. It is utilized as a key indicator of liquidity, ecosystem adoption, and asset inflows. The native bridge, standard gateway, custom gateway, and WETH ERC-20 gateway contracts on Ethereum are included in the tracking.

## 2. Data sources

- **Blockchain events**: ERC-20 token transfers and native token transfers associated with specific bridge escrow addresses, covering Ethereum
- **External data**: End-of-day price feeds and asset metadata

## 3. Step-by-step calculation

### Component A: Bridge escrow address tracking

- **Purpose**: The identification and isolation of the specific bridge and gateway contracts on Ethereum.
- **Logic**: Daily token and native asset flows are filtered for the designated Robinhood Chain bridge escrow addresses on Ethereum. The native bridge, standard gateway, custom gateway, and WETH gateway contracts are included in these addresses.
- **Key fields**: `account_address`, `token_address`, `amount`

### Component B: Daily balance accumulation

- **Purpose**: The calculation of the running balance of each asset held in the escrow contracts.
- **Logic**: Net daily flows for both native and ERC-20 assets are aggregated. A cumulative sum is applied over the historical time series to determine the daily balance of each asset. A fill-forward algorithm is executed to propagate the last known balance to days with no transfer activity.
- **Key fields**: `timestamp`, `amount`

### Component C: Valuation and aggregation

- **Purpose**: The conversion of asset balances to USD and aggregation to the product level.
- **Logic**: Asset balances are normalized by decimal precision and multiplied by end-of-day asset prices. The USD values of all assets held across the tracked escrow addresses are summed daily. The final metric is aggregated under the Robinhood Chain product, with a fill-forward strategy applied to handle any gaps in the daily time series.
- **Key fields**: `balance`, `price_usd`, `bridge_deposits`
