# Flow Transaction participants (daily) Methodology

## 1. Overview

Transaction participants (daily) measures the number of unique addresses that participate in transactions on Flow and Flow EVM within a 24-hour window. This metric captures a comprehensive view of activity by including not only transaction signers (payers, proposers, and authorizers) but also recipients of non-native fungible tokens and NFTs. On Flow, recipients are included as active participants because they must actively set up vaults or collections to receive these specific assets.

## 2. Data sources

- **Blockchain events**: `Deposited` events from `FungibleToken` and `NonFungibleToken` contracts, along with transaction and collection records, covering Flow and Flow EVM.

## 3. Step-by-step calculation

### Component A: Flow transaction signer extraction

- **Purpose**: Identifies addresses that initiate, propose, or authorize transactions on Flow.
- **Logic**: Addresses are extracted from three distinct roles within Flow transactions. Payers are identified as the accounts responsible for paying transaction fees. Proposers are identified via the proposal key address. Authorizers are identified by unnesting the authorizers field within the transaction data stored in block collections.
- **Key fields**: `payer`, `proposal_key_address`, `authorizer`

### Component B: Flow asset recipient extraction

- **Purpose**: Captures addresses that actively receive non-native assets on Flow.
- **Logic**: `Deposited` events are parsed from `FungibleToken` and `NonFungibleToken` contracts. For fungible tokens, the recipient address is extracted from the event payload, excluding the native Flow token contract. For non-fungible tokens, recipient addresses are extracted from `Deposited` events emitted by the core NFT contract. These recipients are classified as participants due to the requirement for accounts to be initialized to receive these assets.
- **Key fields**: `to` address from event payloads, `contract_address`, `event_name`

### Component C: Flow EVM user extraction

- **Purpose**: Identifies active addresses interacting with Flow EVM.
- **Logic**: Transaction records from Flow EVM are parsed to identify the originating address for every transaction. The `from_address` is extracted for all successful transactions recorded on the EVM layer.
- **Key fields**: `from_address`

### Component D: Daily aggregation and deduplication

- **Purpose**: Consolidates all participants into a single daily metric.
- **Logic**: All addresses identified as signers, recipients, or EVM users are combined into a single dataset. The number of unique addresses is calculated for each 24-hour period using UTC day boundaries. Dimensions are preserved for chain-level and product-level breakdowns between Flow and Flow EVM.
- **Key fields**: `block_timestamp`, `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.
