Manta Pacific batches users' transactions and submits them to Ethereum, paying a share of the transaction fees to Ethereum validators (expense). Manta Pacific stores call data on Celestia’s modular data availability network.

Manta Pacific is an L2 smart contract platform for decentralized applications on Ethereum. Manta Pacific was founded by Manta Network and launched in 2023.

Manta Network team owns and governs the protocol. Manta Network's investors include Polychain Capital, Qiming Venture Partners, Binance Labs, etc.

# Manta Fees Methodology

## 1. Overview

Fees measures the total value paid by users to execute transactions on Manta Pacific. Transaction fees are collected to cover both execution gas and Layer 1 data availability costs. The economic value generated by the network is represented by these fees, which are paid in the native gas asset. This metric is utilized to evaluate the overall demand and economic activity on the blockchain.

## 2. Data sources

- **Blockchain events**: Transaction execution data on Manta Pacific
- **External data**: End-of-day price feeds for the native gas asset

## 3. Step-by-step calculation

### Component A: Transaction fee extraction

- **Purpose**: Extract execution gas fees and Layer 1 data availability fees from transaction receipts
- **Logic**: Transaction receipts are parsed to extract gas used, effective gas price, Layer 1 gas used, Layer 1 gas price, and the Layer 1 fee scalar. Execution fees are calculated by multiplying the gas used by the effective gas price. Layer 1 fees are calculated by multiplying the Layer 1 gas used, Layer 1 gas price, and Layer 1 fee scalar.
- **Key fields**: `gas_used`, `effective_gas_price`, `l1_gas_used`, `l1_gas_price`, `l1_fee_scalar`

### Component B: Daily aggregation and normalization

- **Purpose**: Aggregate transaction fees to a daily granularity and normalize the values
- **Logic**: Execution fees and Layer 1 fees are summed separately for each day. The Layer 1 fee amounts are normalized by decimal precision. The total fee is calculated as the sum of the daily execution fee and the daily Layer 1 fee.
- **Key fields**: `fee_amount`, `l1_fee_amount`

### Component C: USD conversion and finalization

- **Purpose**: Convert the aggregated fees to USD and finalize the metric
- **Logic**: Daily fee amounts are multiplied by the end-of-day price of the native gas asset on Ethereum. The resulting USD values are mapped to the Manta chain identifier. Missing days are filled with zeros to ensure a continuous time series.
- **Key fields**: `fees`, `price_usd`
