Ink batches users' transactions and submits them to Ethereum, paying a share of the transaction fees to Ethereum validators (expense).

Ink is an Ethereum Layer 2 (L2) blockchain built on Optimism's Superchain, focused on providing a secure, scalable infrastructure for Web3 applications.

Kraken team owns and governs the protocol. Kraken's investors include RIT Capital Partners, Hummingbird Ventures, Money Partners Group, etc.

Blockchains (L2)

# Ink Superchain fees Methodology

## 1. Overview

Superchain fees represent the portion of Layer 2 gas fees allocated to the Superchain ecosystem. For Ink blockchain, 15% of all L2 gas fees are designated as Superchain fees. This metric quantifies the revenue share flowing to the broader Superchain network from Ink's transaction activity, providing insight into the economic contribution of individual L2 chains to the Superchain infrastructure.

## 2. Data sources

- **Ink blockchain transaction records**: Complete transaction data from Ink blockchain including gas usage metrics, transaction metadata, and pricing information
- **End-of-day token price feeds**: ETH price data used for USD conversion of fee amounts
- **ETH token metadata**: Hardcoded token information for ETH on Ink blockchain using standard contract address

## 3. Step-by-step calculation

### Component A: Transaction data processing
- **Purpose**: Extracts and standardizes raw transaction data from Ink blockchain
- **Logic**: Processes raw Ink blockchain transactions by casting all fields to appropriate data types and standardizing the format. Each transaction record includes timing information, participant addresses, and comprehensive gas usage metrics. The ETH token is identified using the standard contract address `0x4200000000000000000000000000000000000006` and labeled with symbol `ETH`
- **Key fields**: `block_timestamp` for timing, `transaction_hash` for unique identification, `from_address` and `to_address` for participants, `gas_used` for L2 execution cost, `l1_gas_used` for L1 settlement cost, `gas_price` for L2 pricing, `l1_gas_price` and `l1_fee_scalar` for L1 cost calculation

### Component B: Gas fee calculation  
- **Purpose**: Calculates actual ETH amounts paid in gas fees for both L2 and L1 components
- **Logic**: Computes L2 gas fees by multiplying `gas_used` by `gas_price`, then converts from wei to ETH by dividing by 1e18. Also calculates L1 gas fees using `l1_gas_used`, `l1_gas_price`, and `l1_fee_scalar` with the same wei-to-ETH conversion. Maintains transaction-level granularity with all original metadata
- **Key fields**: `l2_gas_fee` as the primary L2 execution cost in ETH, `l1_gas_fee` for L1 settlement costs, all original transaction identifiers and metadata

### Final aggregation
- **Combining components**: Takes the calculated L2 gas fees and applies the 15% Superchain allocation by multiplying each `l2_gas_fee` by 0.15 to determine the `superchain_fees` amount
- **Currency conversion**: Converts ETH amounts to USD using end-of-day price feeds through the standard Token Terminal conversion process, maintaining decimal precision without additional corrections
- **Time aggregation**: Aggregates transaction-level data to daily boundaries by truncating `block_timestamp` to day level, summing all Superchain fees within each day
- **Final calculation**: Daily Superchain fees equal the sum of (L2 gas fee × 0.15) for all transactions in that day, converted to USD. Missing days are filled with zero values to maintain complete time series continuity
