Collators aggregate parachain transactions block candidates and producing state transition proofs for validators based on those blocks.

NeuroWeb is a decentralized Artificial Intelligence blockchain powered by Polkadot Relay chain.

NEURO holders own and govern the protocol.

# NeuroWeb Supply-side fees Methodology

## 1. Overview

The share of fees that goes to service providers, such as validators and stakers, is measured by the supply-side fees metric for NeuroWeb. For NeuroWeb, this metric is consistently zero, as transaction fees are not distributed to supply-side participants. Calculations are based on total transaction fees aggregated across the NeuroWeb parachain and NeuroWeb EVM layers.

## 2. Data sources

- **Blockchain events**: `TransactionFeePaid` events from `transactionPayment` contracts, `Executed` events from `ethereum` contracts, and `Withdraw` and `Deposit` events from `balances` contracts, plus account mapping data linking parachain and EVM addresses, covering NeuroWeb and NeuroWeb EVM
- **External data**: End-of-day price feeds for the NeuroWeb asset

## 3. Step-by-step calculation

### Component A: NeuroWeb parachain fee extraction

- **Purpose**: Captures transaction fees paid on the NeuroWeb parachain layer
- **Logic**: `TransactionFeePaid` events are extracted from the `transactionPayment` pallet. Base transaction fees and additional tips are summed to calculate the total transaction cost per extrinsic. Amounts are normalized by decimal precision.
- **Key fields**: `transaction_fee`, `transaction_tip`, `extrinsic_id`

### Component B: NeuroWeb EVM fee extraction

- **Purpose**: Captures transaction fees from NeuroWeb EVM
- **Logic**: EVM transaction costs are tracked through balance movements in the `balances` pallet. `Withdraw` events represent fee deductions and `Deposit` events represent refunds. Transaction signers are validated against execution events from the `ethereum` pallet using account mapping data that links parachain accounts to EVM addresses. Fees are aggregated by transaction and normalized by decimal precision.
- **Key fields**: `transaction_fee`, `signer_address`, `extrinsic_id`

### Component C: Fee aggregation and USD conversion

- **Purpose**: Combines parachain and EVM fees and normalizes to USD
- **Logic**: Fee data from the NeuroWeb and NeuroWeb EVM layers are combined into a single dataset. Daily fee totals are converted to USD using end-of-day price feeds for the NeuroWeb asset.
- **Key fields**: `transaction_fee`, `fees_usd`

### Component D: Supply-side fee allocation

- **Purpose**: Determines the share of fees distributed to supply-side participants
- **Logic**: Supply-side fees are explicitly set to zero for all time periods. This indicates that the protocol does not currently distribute collected transaction fees to supply-side network participants such as validators or stakers.
