# Active users (monthly) Methodology

## 1. Overview

Active users (monthly) measures the number of unique addresses that execute or authorize revenue-generating transactions on the Flow network. This metric accounts for activity across both the Flow Cadence and Flow EVM environments, ensuring a comprehensive view of network adoption. Unique addresses are aggregated over a 30-day rolling window based on UTC timestamps.

## 2. Data sources

- **Blockchain events**: Transaction and collection records from Flow and Flow EVM
- **External data**: Asset metadata for address and product identification

## 3. Step-by-step calculation

### Component A: Flow EVM user identification

- **Purpose**: Identify unique active addresses within the Flow EVM environment.
- **Logic**: Transaction records from Flow EVM are parsed to extract the sender address from each transaction. Every unique address identified as a transaction initiator is classified as an active user for the given 30-day window.
- **Key fields**: `block_timestamp` (timing) and `from_address` (user identification).

### Component B: Flow user identification

- **Purpose**: Identify unique active addresses within the Flow (Cadence) environment across multiple signer roles.
- **Logic**: User addresses are extracted from three distinct signer roles within Flow transaction and collection records. Payers are identified as the addresses responsible for transaction fees. Proposers are identified via the proposal key addresses. Authorizers are identified by unnesting and extracting all addresses that provided authorization for transactions within collection data. These roles are combined to form the total set of unique active addresses for the Cadence environment.
- **Key fields**: `payer`, `proposal_key_address`, and `authorizers` (user identification).

### Component C: Monthly aggregation and de-duplication

- **Purpose**: Combine activity from all network environments and calculate the final monthly metric.
- **Logic**: The address sets identified from both Flow EVM and Flow are combined. De-duplication is performed to ensure that an address interacting with multiple environments or performing multiple roles within the same 30-day rolling window is only counted as a single active user. The final count is aggregated per 30-day window using UTC boundaries.
- **Key fields**: `block_timestamp` and `user_address`.

Blockchains (L1)

Validators process transactions and receive fees from users (supply-side fees).

Flow is a smart contract platform for decentralized applications (a blockchain). Flow was founded by Roham Gharegozlou, Dieter Shirley and Mikhael Naayem and launched in 2019.

FLOW holders own and govern the protocol. They currently don’t take a cut of the total transaction fees paid by users (revenue). Flow’s investors include a16z, Coatue, Coinfund, Fabric Ventures, etc.
