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 Revenue Methodology

## 1. Overview

The Allbridge revenue metric measures the fee income generated by the Allbridge bridge protocol from cross-chain transfers. Revenue is calculated by applying a percentage fee to the total USD value of bridge transfers processed by the protocol. The fee structure changed on January 30, 2023, increasing from 0.02% to 0.06% of transfer volume.

## 2. Data sources

The calculation relies on several key data sources:
- **Blockchain events**: Parsed `TokensSent` and `TokensReceived` events from Allbridge bridge contracts deployed on BSC, Ethereum, and Polygon networks
- **Bridge contracts**: Multiple versions of Allbridge contracts (`Bridge` and `Bridge2`) across supported chains
- **Token data**: Stablecoin transfer amounts and token address mappings for BUSD (BSC) and USDC (Ethereum, Polygon)
- **Chain metadata**: Allbridge-specific chain ID mappings for cross-chain transfer routing
- **External data**: End-of-day token price feeds for USD conversion and token metadata for decimal normalization

## 3. Step-by-step calculation

### Component A: Bridge transfer event extraction
- **Purpose**: Captures all cross-chain transfer events from Allbridge bridge contracts
- **Logic**: Extracts `TokensSent` events from BSC, Ethereum, and Polygon chains, capturing transfer details including token addresses, destination chain IDs, and transfer amounts. Also extracts `TokensReceived` events from the same chains to capture transfers originating from Tron and Solana where direct event parsing is not available. Events are sourced from both Bridge and Bridge2 contract versions across all supported chains.
- **Key fields**: `receiveToken` addresses are normalized to standard format, `destinationChainId` and `amount` fields are converted to numeric types, and `message` field in received events contains encoded origin chain information

### Component B: Cross-chain transfer processing
- **Purpose**: Processes and normalizes transfer data across different blockchain networks
- **Logic**: For sent transfers, destination chain IDs are mapped to chain names using Allbridge's internal chain ID system. Token addresses are standardized to reference equivalent stablecoins across chains. For received transfers, origin chain IDs are extracted from encoded message data and filtered to include only transfers from Tron (chain ID 3) and Solana (chain ID 4) to prevent double counting. Transfer amounts undergo decimal correction to normalize different token decimal representations.
- **Key fields**: `token_address` field is mapped to BUSD address on BSC and USDC addresses on Ethereum and Polygon, `transfer_amount` values are divided by 1000 for sent transfers and processed through decimal correction for received transfers

### Component C: Transfer volume aggregation
- **Purpose**: Combines all transfer data and calculates daily transfer volumes
- **Logic**: Sent transfers and received transfers from Tron/Solana are combined into a unified dataset. Transfer volumes are aggregated by day, chain, and token address to calculate total daily volumes. The data is categorized under the 'bridges' market sector and 'mint_and_burn' business segment. Stablecoin volumes are converted to USD using end-of-day price feeds.
- **Key fields**: `transfer_volume` represents the sum of all transfer amounts, timestamp is truncated to day granularity, and `chain_id` identifies the blockchain network

### Final calculation
- **Combining components**: Daily transfer volumes serve as the base for revenue calculation
- **Currency conversion**: Transfer volumes are converted to USD using end-of-day price feeds before revenue calculation
- **Time-based fee application**: Revenue is calculated by multiplying transfer volume by the applicable fee percentage - 0.02% (0.0002) for transfers before January 30, 2023, and 0.06% (0.0006) for transfers on or after that date
- **Final calculation**: Revenue = Transfer Volume × Fee Percentage, where the fee percentage is determined by the transfer timestamp relative to the fee update date of 2023-01-30
