# Active users (daily) Methodology

## 1. Overview

Active users (daily) is measured as the number of unique addresses that make a revenue-generating transaction with LayerZero V2. User adoption and protocol activity are tracked by identifying unique participants who send or receive cross-chain messages and assets via the LayerZero V2 infrastructure. Each unique address is counted once per 24-hour window, providing a standardized measure of daily engagement across all supported blockchain environments.

## 2. Data sources

- **Blockchain events**: `PacketDelivered` events and `send` function calls from `EndpointV2` contracts, and `OFTReceived` and `OFTSent` events from `OFT` contracts, covering Ethereum, Arbitrum, Avalanche, Base, and 26 other chains

## 3. Step-by-step calculation

### Component A: Endpoint and messaging activity

- **Purpose**: Identify unique users interacting with the core LayerZero V2 messaging infrastructure
- **Logic**: Transaction senders are extracted from `send` function calls executed on `EndpointV2` contracts. Transaction receivers are identified from `PacketDelivered` events emitted by `EndpointV2` contracts. These addresses are collected and normalized to represent the primary participants initiating and receiving cross-chain communications.
- **Key fields**: `from_address`, `receiver`

### Component B: OmniChain Fungible Token (OFT) activity

- **Purpose**: Capture user interactions involving the transfer of OFT-standard assets
- **Logic**: Senders of OmniChain assets are identified by parsing `OFTSent` events from `OFT` contracts. Recipients of these assets are extracted from `OFTReceived` events emitted by the same contracts. Through this process, all users engaged in cross-chain asset movements facilitated by LayerZero V2 are accounted for in the activity metrics.
- **Key fields**: `fromAddress`, `toAddress`

### Component C: Daily deduplication and aggregation

- **Purpose**: Consolidate user activity into a distinct daily count
- **Logic**: All addresses identified from messaging and asset transfer components are aggregated into a single dataset. Distinct counts of unique addresses are calculated per day using UTC 00:00 boundaries. The final metric is generated by deduplicating addresses at the day, chain, and product level to ensure accurate reporting of unique active users (daily).
- **Key fields**: `block_timestamp`, `user_address`

Interoperability

LayerZero uses a decentralized network of Validator Nodes to facilitate secure and fast communication between different blockchains.

LayerZero allows users to send and receive messages between different blockchains, and to bridge tokens between different blockchains.

LayerZero is a cross-chain interoperability protocol that enables secure and fast communication between different blockchains.
