The Zircuit staking program allows users and communities to help bootstrap liquidity for Zircuit. Users deposit assets (net deposits) and receive Zircuit Points and native staking yield.

Zircuit is an L2 smart contract platform for decentralized applications on Ethereum. Zircuit was founded in 2023 and launched their Testnet in November 2023.

Zircuit team and investors currently own and govern the protocol. Zircuit’s investors include Pantera, Dragonfly Capital, and Maelstrom.

# Zircuit Bridge deposits Methodology

## 1. Overview

Bridge deposits represents the total USD value of tokens held in Zircuit's designated bridge contract addresses on Ethereum. This metric tracks the aggregate value of user deposits that are locked in bridge contracts as users transfer assets from Ethereum to the Zircuit Layer 2 network. The metric provides insight into capital flow and user adoption of the Zircuit bridge infrastructure.

## 2. Data sources

- **Ethereum token transfer events**: Parsed `Transfer` events from ERC-20 token contracts to track token movements into and out of bridge addresses
- **Ethereum transaction traces**: Transaction execution traces that provide context for token transfer events and contract interactions
- **End-of-day token price feeds**: USD price data for tokens held in bridge contracts, used for portfolio valuation
- **Token metadata**: Contract information including token symbols, names, and decimal precision for proper balance calculations
- **Blockchain timestamp data**: Block timestamp information for accurate time-series aggregation

## 3. Step-by-step calculation

### Component A: Bridge address portfolio tracking
- **Purpose**: Monitor token balances held by Zircuit's bridge contract addresses on Ethereum
- **Logic**: Track all token transfers involving two specific Ethereum addresses (`0x17bfafa932d2e23bd9b909fd5b4d2a27043fb1` and `0x386b76d9ca5f5fb150b6bfb35cf5379b22b26dd8`). For each address, calculate running balances for all ERC-20 tokens by processing inbound and outbound `Transfer` events. Convert raw token amounts to human-readable values using each token's decimal precision.
- **Key fields**: Bridge contract addresses, token contract addresses, transfer `amount` values, block `timestamp`, token `decimals`

### Component B: USD valuation
- **Purpose**: Convert token balances to USD values for aggregated portfolio tracking
- **Logic**: For each token balance held by the bridge addresses, multiply the token amount by the corresponding end-of-day USD price. Handle cases where price data may be missing or delayed. Apply appropriate decimal corrections to ensure accurate USD conversion.
- **Key fields**: Token `balance` amounts, `price` in USD, converted USD `value`

### Component C: Business metadata application  
- **Purpose**: Apply standard business categorization for metric reporting
- **Logic**: Tag each balance record with business segment information including chain identifier (Ethereum), market sector (`blockchains_l2`), business segment (`blockchain`), and null product identifier. Maintain timestamp granularity for time-series analysis.
- **Key fields**: `chain_id`, `market_sector_id`, `business_segment_id`, `product_id`, `timestamp_grain`

### Final aggregation
- **Combining components**: Sum USD values across all tokens held by both bridge addresses, grouping by timestamp, chain, and business metadata fields to create daily portfolio snapshots
- **Currency conversion**: All token balances are converted to USD using end-of-day price feeds, with proper decimal handling for each token type
- **Time aggregation**: Data is aggregated to daily boundaries based on block timestamps, with forward-fill logic applied to maintain continuity during periods without bridge activity
- **Final calculation**: The final `bridge_deposits` value represents the total USD value of all tokens held across Zircuit's bridge contract addresses at each point in time, providing a measure of capital locked in the bridge infrastructure
