# deBridge Liquidity Network (DLN) Revenue Methodology

## 1. Overview

Revenue measures the total portion of fees retained by the deBridge Liquidity Network (DLN) treasury. This metric represents the protocol's earnings from cross-chain limit orders and transfers before accounting for operating expenses. For deBridge Liquidity Network (DLN), the protocol take rate is set at 100%, meaning all fees collected from users are classified as revenue.

## 2. Data sources

- **Blockchain events**: `CreatedOrder` events from `DlnSource` and `DlnSourceV1` contracts, covering Arbitrum, Avalanche, Base, BSC, and 4 other chains
- **External data**: End-of-day price feeds for native gas assets and transferred assets

## 3. Step-by-step calculation

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

- **Purpose**: To identify and extract fee payments associated with cross-chain orders.
- **Logic**: `CreatedOrder` events are parsed from `DlnSource` and `DlnSourceV1` contracts across all supported chains. Two specific fee types are captured: a flat fee denominated in the source chain's native asset and a percentage-based fee denominated in the asset being transferred. These values are extracted from each event and associated with the respective asset addresses for accurate valuation.
- **Key fields**: `nativeFixFee` (flat fee), `percentFee` (percentage fee), and `giveTokenAddress` (transferred asset identifier).

### Component B: Protocol revenue allocation

- **Purpose**: To determine the share of fees retained by the protocol treasury.
- **Logic**: A 100% allocation is applied to all identified fees. Revenue is derived directly from the fees metric as no portion of these specific fees is distributed to supply-side participants or external infrastructure providers.

### Component C: USD normalization and aggregation

- **Purpose**: To convert multi-chain asset fees into a standardized USD valuation.
- **Logic**: Fee amounts are normalized by the decimal precision of each asset. These values are then multiplied by end-of-day price feeds. The resulting USD values are aggregated by day and chain using UTC day boundaries to produce the final daily revenue figures.

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.
