# Active users (monthly) Methodology

## 1. Overview

Active users (monthly) measures the number of unique addresses that make a revenue-generating transaction with LayerZero V1. This metric captures activity from both users initiating cross-chain messages on a source chain and those receiving delivered packets on a destination chain. It serves as a primary indicator of user adoption and network utility across the supported LayerZero V1 ecosystem.

## 2. Data sources

- **Blockchain events**: `PacketDelivered` events from `ReceiveUln301` contracts, `SendToChain` events from `OFT` contracts, and `send` function calls from `EndpointV1` contracts, covering Ethereum, Arbitrum, Avalanche, Base, and 17 other chains

## 3. Step-by-step calculation

### Component A: Message initiation tracking

- **Purpose**: Identify unique addresses initiating cross-chain communication or asset transfers.
- **Logic**: User addresses are extracted from the transaction sender field of `send` function calls on `EndpointV1` contracts. Additionally, senders are identified from `SendToChain` events emitted by `OFT` contracts. These interactions represent the active user base on the origin chain of any LayerZero V1 transaction.
- **Key fields**: `from_address` (sender), `user_address` (initiator)

### Component B: Message delivery tracking

- **Purpose**: Identify unique addresses interacting with the protocol as receivers on the destination chain.
- **Logic**: Transaction receivers are identified from `PacketDelivered` events emitted by `ReceiveUln301` contracts. This ensures that the active user count accounts for the completed lifecycle of cross-chain messages, capturing the relevant participant address at the message destination.
- **Key fields**: `receiver` (inbound message recipient)

### Component C: Distinct user aggregation

- **Purpose**: Consolidate sender and receiver data into a single monthly active user count.
- **Logic**: Addresses from all identified initiation and delivery interactions are aggregated by 30-day window and chain. A distinct count is performed on these addresses to ensure each unique entity is counted only once per 30-day rolling window. Only activity categorized as LayerZero V1 is included, with related product activity, such as Stargate, being excluded to ensure product-level specificity.
- **Key fields**: `user_address` (unique identifier), `block_timestamp` (timing)

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.
