# Sound.xyz Active users (weekly) Methodology

## 1. Overview

Active users (weekly) measures the number of unique addresses that perform revenue-generating actions on Sound.xyz within a 7-day rolling window. This metric captures the core participants of the music NFT ecosystem, including collectors minting or purchasing music editions and artists deploying new editions or creating artist profiles. By tracking unique interactions across primary mints and secondary marketplace swaps, active users (weekly) serves as a key indicator of user growth and engagement for the Sound.xyz platform.

## 2. Data sources

- **Blockchain events**: `EditionPurchased` events from `Artist` and `ArtistV1` contracts; `Minted` events from `MerkleDropMinter` and `RangeEditionMinter` contracts (including V1, V2, Bankless, Bonfire, and InvinMusic versions); `Bought` and `Sold` events from `SAM`, `SAMV1`, and `SAMV2` contracts; `SoundEditionCreated` events from `Creator` contracts; and `CreatedArtist` events from `ArtistCreator` contracts, covering Ethereum and Optimism.

## 3. Step-by-step calculation

### Component A: Music edition collection and minting

- **Purpose**: To identify unique users purchasing or minting music NFTs.
- **Logic**: User addresses are extracted from the buyer fields of `EditionPurchased` events emitted by `Artist` and `ArtistV1` contracts. Similarly, participant addresses are identified from the buyer fields of `Minted` events emitted by various versions of `MerkleDropMinter` and `RangeEditionMinter` contracts. These events represent primary market activity where users acquire music assets directly from the protocol.
- **Key fields**: `buyer`, `block_timestamp`, `transaction_hash`

### Component B: Marketplace swap activity

- **Purpose**: To capture users interacting with the Sound Automated Market (SAM).
- **Logic**: Unique addresses are identified from marketplace interactions using the Sound.xyz liquidity layer. Buyer addresses are extracted from `Bought` events, and seller addresses are extracted from `Sold` events across `SAM`, `SAMV1`, and `SAMV2` contracts. This ensures that both liquidity providers and traders are reflected in the weekly activity counts.
- **Key fields**: `buyer`, `seller`, `block_timestamp`, `transaction_hash`

### Component C: Artist and edition creation

- **Purpose**: To track the activity of creators and artists on the platform.
- **Logic**: Deployer addresses are extracted from `SoundEditionCreated` events emitted by `Creator` contracts. Additionally, artist addresses are identified by joining `CreatedArtist` events from `ArtistCreator` contracts with transaction data to capture the originating `from_address` of the transaction signer. This captures the active participation of artists establishing their presence or releasing new content.
- **Key fields**: `deployer`, `from_address`, `block_timestamp`, `transaction_hash`

### Component D: Weekly aggregation

- **Purpose**: To calculate the final count of unique weekly participants.
- **Logic**: All identified addresses from the collection, marketplace, and creation components are pooled and de-duplicated within each 7-day rolling window. The metric is calculated as the count of unique addresses per chain. Weekly granularity is maintained using 7-day rolling windows to ensure consistent reporting of active users (weekly) across all supported networks.
