Liquidity providers deposit funds into SpookySwap and receive trading fees from traders (supply-side fees).

SpookySwap is a non-custodial exchange protocol built on Fantom. SpookySwap was launched in April 2021.

BOO tokenholders own and govern the protocol. They currently take a cut of the total interest paid by borrowers (revenue).

# SpookySwap Tradeable assets Methodology

## 1. Overview

The tradeable assets metric measures the cumulative number of unique tokens available for trading on SpookySwap over time. This metric answers the business question: "How many different tokens can users trade on SpookySwap as of any given date?" The calculation tracks when each unique token first appears in any trading pair on the platform and maintains a running total of all tokens that have ever been tradeable.

## 2. Data sources

- **Blockchain events**: Parsed Fantom `PairCreated` events from the SpookySwap V1 PairFactory contract, which are emitted whenever a new trading pair is established on the platform
- **Token metadata**: Token information including symbols and decimal places for tokens on the Fantom network
- **Time boundaries**: Daily timestamp boundaries for aggregating and tracking token appearances

## 3. Step-by-step calculation

### Component A: Trading pair extraction
- **Purpose**: Identifies all trading pairs created on SpookySwap and extracts the token addresses from each pair
- **Logic**: Processes `PairCreated` events from the SpookySwap V1 PairFactory contract on Fantom. Each event contains the addresses of two tokens (`token0` and `token1`) that form a trading pair, along with the pair contract address and creation timestamp. The component also adds a fixed fee tier of 0.002 (0.2%) for all pairs and enriches the data with token metadata including symbols and decimal places
- **Key fields**: `block_timestamp` (when the pair was created), `account_address` (the pair contract), `token0_address` and `token1_address` (the two tokens in the pair), `fee_tier` (always 0.002), and `account_name` (formatted as token0-token1 symbols)

### Component B: Unique token identification and daily aggregation
- **Purpose**: Creates a comprehensive list of all unique tokens that have appeared in trading pairs and determines when each token first became tradeable
- **Logic**: Takes both `token0_address` and `token1_address` from all trading pairs and creates a union to get every unique token address. Truncates timestamps to daily boundaries and finds the first appearance date for each unique token using MIN aggregation. Groups the results by day to count how many new unique tokens became tradeable on each date. Applies gap-filling logic to ensure days with no new tokens are represented with zero values
- **Key fields**: `timestamp` (daily boundaries), `chain` (always Fantom), `token_address` (unique token identifiers), and `asset_count` (count of new tokens per day)

### Final aggregation
- **Combining components**: The daily new token counts are processed through a cumulative sum calculation partitioned by chain and ordered by timestamp
- **Currency conversion**: No currency conversion is needed as this metric counts tokens rather than measuring monetary values
- **Time aggregation**: Data is aggregated to daily boundaries, with the first appearance date determining when each token is counted
- **Final calculation**: A running cumulative sum calculates the total number of unique tokens that have ever been tradeable on SpookySwap as of each date. The metric increases whenever new tokens appear in trading pairs and never decreases, representing the growing universe of tradeable assets on the platform
