Allbridge Core allows users to send stablecoins from one chain to another almost immediately by using native liquidity pools deployed across 5 EVM and non-EVM blockchains. Liquidity providers receive the majority of transfer fees paid by users (supply-side fees).

Allbridge Core is a cross-chain stablecoin bridge. Allbridge Core was co-founded by Yuriy Savchenko and Andriy Velykyy, and was launched in September 2022.

The Allbridge team own and govern the protocol. They currently take a cut of the transfer fees paid by the users (revenue). Allbridge Core’s investors include Race Capital and others.

# Allbridge Core Earnings Methodology

## 1. Overview

Allbridge earnings represent the net profit generated by the Allbridge Core cross-chain bridge protocol. The metric is calculated as revenue minus expenses, where revenue comes from fees charged on bridge transfers and expenses represent token incentives paid to users. Currently, Allbridge does not distribute token incentives, making earnings equal to revenue. This metric answers how much profit the protocol generates from its cross-chain bridge operations across supported blockchain networks.

## 2. Data sources

- **Blockchain events**: Parsed Allbridge `TokensSent` and `TokensReceived` events from Ethereum, BSC, and Polygon smart contracts capturing cross-chain bridge transfers
- **Cross-chain transfer data**: `TokensReceived` events from Ethereum, BSC, and Polygon that track inbound transfers originating from Tron and Solana chains
- **Token price data**: End-of-day token price feeds for converting stablecoin transfer volumes to USD values
- **Token metadata**: Token contract information including decimal places for accurate amount calculations
- **Protocol configuration**: Hardcoded fee percentage rates and their effective dates, chain ID mappings, and token address mappings for cross-chain consistency

## 3. Step-by-step calculation

### Component A: Bridge transfer volume extraction
- **Purpose**: Captures all cross-chain bridge transfers processed by Allbridge across supported chains
- **Logic**: Extracts `TokensSent` events from Allbridge smart contracts on Ethereum, BSC, and Polygon, recording transfer amounts, origin chains, destination chains, and token addresses. To avoid double-counting while capturing complete volume, supplements with `TokensReceived` events on Ethereum, BSC, and Polygon that specifically track transfers originating from Tron and Solana (chains 3 and 4). Normalizes token addresses across chains by using USDC on Ethereum as a proxy for Tron and Solana transfers, and applies appropriate stablecoin addresses for each destination chain (BUSD for BSC, USDC for Ethereum and Polygon)
- **Key fields**: `block_timestamp` for timing, `transfer_amount` for volume, `origin_chain` and `destination_chain` for routing, `token_address` for asset identification

### Component B: Volume normalization and USD conversion
- **Purpose**: Standardizes transfer amounts and converts them to USD values for consistent measurement
- **Logic**: Corrects decimal places for transfer amounts, with sent transfers divided by 1000 and received transfers processed through decimal correction macros based on token metadata. Groups transfers by day, chain, and token address, then sums total daily transfer volume. Converts stablecoin volumes to USD using end-of-day price feeds, treating the stablecoins as approximately equal to USD
- **Key fields**: `transfer_volume` in normalized decimals, `timestamp` truncated to daily boundaries, `chain_id` for network identification

### Component C: Revenue calculation
- **Purpose**: Calculates protocol revenue by applying time-based fee percentages to transfer volumes
- **Logic**: Applies different revenue percentages based on the transfer date - 0.02% (0.0002) for transfers before January 30, 2023, and 0.06% (0.0006) for transfers after this date. Multiplies the daily transfer volume by the applicable percentage rate to determine revenue for each chain and day
- **Key fields**: `revenue` calculated as volume multiplied by percentage rate, `timestamp` for date-based logic

### Component D: Expenses calculation  
- **Purpose**: Determines protocol expenses from token incentive distributions
- **Logic**: Sets token incentives to zero across all time periods and chains, as Allbridge does not currently distribute token incentives to users. This results in expenses being consistently zero
- **Key fields**: `expenses` set to 0, `token_incentives` as the source of expenses

### Final aggregation
- **Combining components**: Revenue and expenses are combined through subtraction (revenue minus expenses) using the earnings calculation macro
- **Currency conversion**: All amounts are already converted to USD through the volume calculation process using end-of-day price feeds
- **Time aggregation**: Data is aggregated to daily boundaries using timestamp truncation to day level
- **Final calculation**: Since expenses are zero, earnings equal revenue, which is the daily transfer volume multiplied by the time-based fee percentage (0.02% before January 30, 2023, and 0.06% afterward)
