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 Average fees per user (AFPU) Methodology

## 1. Overview

Average fees per user (AFPU) measures the average transaction fees paid per active user over a 24-hour window. The metric is calculated as total daily fees divided by active users (daily), reflecting the daily cost incurred by an individual user for utilizing the network's services. This economic indicator is utilized to evaluate user transaction costs and blockspace demand across Manta's core products, including Manta Pacific and Manta Atlantic.

## 2. Data sources

- **Fees**: Derived from the Fees metric
- **Active users (daily)**: Derived from the Active users (daily) metric

## 3. Step-by-step calculation

### Component A: Manta Pacific fee extraction

- **Purpose**: Calculate the total gas fees paid on Manta Pacific
- **Logic**: Gas fees are extracted from Manta Pacific transactions. For each transaction, the execution fee is calculated by multiplying the gas used by the effective gas price. The L1 security fee is calculated by multiplying the L1 gas used, L1 gas price, and L1 fee scalar, and then normalizing the result by decimal precision. The total transaction fee is computed as the sum of the execution fee and the L1 security fee.
- **Key fields**: `gas_used`, `effective_gas_price`, `l1_gas_used`, `l1_gas_price`, `l1_fee_scalar`

### Component B: Daily active user tracking

- **Purpose**: Identify unique active users across Manta Pacific and Manta Atlantic
- **Logic**: Transaction senders are extracted from Manta Pacific transactions and Manta Atlantic extrinsics. These sender addresses are combined using a union operation. Unique active users are aggregated daily to determine the active users (daily) metric.
- **Key fields**: `from_address`, `user_address`

### Component C: USD normalization and aggregation

- **Purpose**: Convert fee amounts to USD and aggregate daily
- **Logic**: Daily fee amounts are multiplied by the end-of-day price of the native asset to obtain the USD-denominated fee value. The fees are aggregated to establish the daily total fees.
- **Key fields**: `timestamp`, `price_usd`

### Component D: Average fees per user calculation

- **Purpose**: Calculate the final average fees per user (AFPU) metric
- **Logic**: The total daily USD-denominated fees are divided by the active users (daily) count. If the active users (daily) count is zero, the resulting value is handled safely to avoid division-by-zero errors.
- **Key fields**: `fees`, `user_dau`
