# deBridge Liquidity Network (DLN) Transfer volume Methodology

## 1. Overview

Transfer volume for deBridge Liquidity Network (DLN) is measured as the total value of assets moved across supported blockchains via the protocol. This metric is used to evaluate the protocol's transaction throughput and its capacity to generate fees from intent-based bridging activity. Since users are required to pay fees to facilitate cross-chain transfers, transfer volume is considered a primary indicator of the protocol’s ability to generate revenue and its overall adoption within the cross-chain interoperability sector.

## 2. Data sources

- **Blockchain events**: `ClaimedUnlock` events from `DlnSource` contracts, covering Ethereum, Arbitrum, Base, Polygon, and 4 other chains
- **External data**: End-of-day price feeds and asset metadata

## 3. Step-by-step calculation

### Component A: deBridge Liquidity Network (DLN) event extraction

- **Purpose**: Cross-chain transfer data is identified and extracted from the protocol's smart contracts.
- **Logic**: `ClaimedUnlock` events are parsed from `DlnSource` contracts across all supported chains. The asset address and the raw quantity of the asset being moved are extracted from each event log.
- **Key fields**: `amount` (quantity of assets), `token_address` (asset identification)

### Component B: Asset address normalization

- **Purpose**: Native asset transfers are mapped to canonical wrapped identifiers to ensure accurate valuation.
- **Logic**: For transfers where the asset address is recorded as a null address in the event data, the address is replaced with the corresponding wrapped native token address (such as WETH, WBNB, or WMATIC) for the specific source chain. This process is required to correctly join the transfer data with asset metadata and price feeds.
- **Key fields**: `token_address`

### Component C: USD conversion and aggregation

- **Purpose**: Raw asset quantities are converted into a standardized USD valuation and aggregated for reporting.
- **Logic**: Asset amounts are normalized by decimal precision. These normalized values are multiplied by end-of-day price feeds to calculate the USD value at the time of the transaction. Daily totals are aggregated by chain and product, with day boundaries defined by UTC timestamps.
- **Key fields**: `amount` (normalized), `token_address` (for pricing)

Bridges

deBridge operates two main products: (1) deBridge Messaging - node operators validate cross-chain transactions for data and asset transfers, and (2) DLN (deBridge Liquidity Network) - an order book of cross-chain intents where Makers create intents in the source chain and Takers provide liquidity on the destination chain. Validators currently do not take a cut of transfer fees (supply-side fees).

deBridge is an interoperability protocol with two products: deBridge Messaging enables decentralized transfers of data and assets between blockchains, and DLN (deBridge Liquidity Network) is a cross-chain token bridge and trading infrastructure. deBridge was founded by Alex Smirnov and launched in 2021, with DLN launched in 2023.

The deBridge team and investors own and govern the protocol. They currently take all transfer fees paid by traders (revenue). deBridge's investors include ParaFi Capital, Animoca Brands, Huobi Ventures, Lemniscap, etc. All fees paid by traders are accumulated on smart contracts operated by the deBridge team and will be governed by deBridge token holders.
