# Uniswap V2 Tradeable pairs Methodology

## 1. Overview

Tradeable pairs measures the number of unique token pairs available for trading on the decentralized exchange. The number of direct swap routes offered by the project is reflected by this metric. For Uniswap V2, this metric is calculated as the cumulative count of unique liquidity pools deployed across all supported blockchains. Each liquidity pool is established to enable trading between a specific pair of assets.

## 2. Data sources

- **Blockchain events**: `PairCreated` events from `Factory` contracts, covering Ethereum, Arbitrum, Optimism, Polygon, and 5 other chains
- **Asset metadata**: Decimals and symbols are retrieved for the underlying assets in each pair

## 3. Step-by-step calculation

### Component A: Uniswap V2 pair creation tracking

- **Purpose**: Identify the creation of new trading pairs and their deployment timestamps
- **Logic**: `PairCreated` events are parsed from `Factory` contracts to extract the pool address, the addresses of the two underlying assets, and the block timestamp. The deployment date for each unique pool address is determined by taking the minimum daily-truncated timestamp of its first appearance. The extracted asset addresses are joined with asset metadata to retrieve symbols and decimals.
- **Key fields**: `block_timestamp` (timing), `pair` (pool address), `token0` (first asset address), `token1` (second asset address)

### Component B: Uniswap V2 daily pair aggregation

- **Purpose**: Calculate the number of new trading pairs deployed each day
- **Logic**: Unique pool addresses are grouped by deployment date, chain, and product. The number of distinct pool addresses deployed on each day is aggregated to establish the daily count of new trading pairs. Days with no new pair creations are filled with zero values to ensure a continuous daily time series.
- **Key fields**: `timestamp` (daily-truncated date), `pair_count` (daily count of new pairs)

### Component C: Uniswap V2 cumulative tradeable pairs calculation

- **Purpose**: Calculate the running total of tradeable pairs available on Uniswap V2
- **Logic**: A running cumulative sum of the daily new pair counts is calculated for each chain and product over time. The total number of tradeable pairs available on any given day is represented by this cumulative sum.
- **Key fields**: `tradeable_pairs` (cumulative count of unique trading pairs)

Exchanges (DEX)

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

Uniswap is a non-custodial exchange protocol built on Ethereum. Uniswap was founded by Hayden Adams and launched in 2018.

UNI tokenholders own and govern the protocol. They do not currently take a cut of the total trading fees paid by traders (revenue). Uniswap's investors include Paradigm, a16z, USV, etc.
