A proposer batches users' transactions and assigns proposed blocks to a prover. Both the proposer and the prover earn a portion of the transaction fees collected.

Taiko is an L2 smart contract platform for decentralized applications on Ethereum. Taiko was founded by Daniel Wang, Brecht Devos, and Terence Lam and launched in 2024.

TAIKO tokenholders own and govern the protocol. Taiko's investors include Hashed, GSR, IOSG Ventures, Generative Ventures, etc.

# Taiko Bridge deposits Methodology

## 1. Overview

Bridge deposits represents the total value of assets locked in Taiko's bridge contracts on Ethereum. This metric measures the cumulative USD value of all tokens deposited into Taiko's bridging infrastructure, indicating the total value that users have committed to bridge from Ethereum to the Taiko L2 network. The calculation tracks token balances across specific bridge contract addresses and converts them to USD using end-of-day pricing.

## 2. Data sources

- **Ethereum token transfer events**: Parsed `Transfer` events from ERC-20 token contracts on Ethereum, tracking all inbound and outbound token movements
- **Ethereum native ETH transfers**: Native ETH transfer records and transaction traces capturing ETH movements
- **End-of-day token price feeds**: Daily closing prices for all tokens to enable USD conversion
- **Token metadata**: Token contract information including decimal places, symbols, and contract addresses
- **Ethereum transaction traces**: Transaction execution data to capture complex token movements and contract interactions

## 3. Step-by-step calculation

### Component A: Bridge address identification
- **Purpose**: Identifies the specific Ethereum addresses that serve as Taiko's bridge contracts
- **Logic**: Two hardcoded Ethereum addresses are defined as the target bridge contracts: `0xd60247c6848b7ca29eddf63aa924e53db6ddd8ec` and `0x996282ca11e5deb6b5d122cc3b9a1fcaad4415ab`. These addresses represent the official Taiko bridge infrastructure where users deposit assets for bridging to the L2 network
- **Key fields**: `account_addresses` containing the bridge contract addresses for the ethereum chain

### Component B: Portfolio balance calculation
- **Purpose**: Calculates the current token balances held across all Taiko bridge addresses
- **Logic**: The portfolio calculation processes all token transfer events involving the bridge addresses, tracking both ERC-20 token transfers and native ETH movements. For each token, the system maintains running balances by processing inbound transfers (increasing balance) and outbound transfers (decreasing balance). Token decimal places are normalized using contract metadata, and balances are calculated at daily intervals to create time-series data
- **Key fields**: `balance` representing the normalized token amount held in each bridge address, `timestamp` for daily time boundaries, `chain` identifying the Ethereum network

### Component C: Business categorization
- **Purpose**: Applies business dimension labels to the calculated balances for reporting structure
- **Logic**: Each balance record is tagged with standardized business dimensions including chain identifier (ethereum), market sector classification (blockchains_l2 indicating Layer 2 focus), business segment (blockchain), and product identifier (null for this metric). Balances are summed across all bridge addresses and tokens to create the aggregate bridge deposits value
- **Key fields**: `bridge_deposits` as the total aggregated balance, `chain_id`, `market_sector_id`, `business_segment_id`, and `product_id` for dimensional reporting

### Final aggregation
- **Combining components**: All token balances across both bridge addresses are summed together to create a single bridge deposits value per time period, representing the total value locked across all supported tokens
- **Currency conversion**: Token balances are converted to USD using end-of-day price feeds, with decimal normalization applied based on each token's contract specifications
- **Time aggregation**: Data is aggregated at daily intervals with forward-fill strategy applied to handle missing data periods, ensuring continuous time-series data
- **Final calculation**: The final bridge deposits metric represents the sum of all USD-converted token balances held across Taiko's bridge contract addresses on Ethereum, providing a comprehensive measure of total value locked in the bridging infrastructure
