# Uniswap V3 Tradeable pairs Methodology

## 1. Overview

The Tradeable pairs metric is defined as the cumulative number of unique asset pairs available for trading on Uniswap V3. The total number of direct swap routes offered by the protocol is represented by this metric. Each unique pool created on the platform is tracked to determine the growth of available trading pairs over time. Only Uniswap V3 deployments are considered for this product-level methodology.

## 2. Data sources

- **Blockchain events**: `PoolCreated` events from `Factory` contracts and historical pool creation records for Optimism pre-regenesis, covering Ethereum, Arbitrum, Optimism, Polygon, and 11 other chains
- **External data**: Asset metadata for symbol and decimal resolution

## 3. Step-by-step calculation

### Component A: Pool creation tracking

- **Purpose**: Identify all unique liquidity pools initialized on Uniswap V3.
- **Logic**: `PoolCreated` events are parsed from `Factory` contracts across all supported chains. For Optimism, historical pool creations prior to the network regenesis are also ingested from seed records. For each pool, the block timestamp, pool address, asset addresses, and fee tier are extracted. The fee tier is normalized by dividing the raw fee value by 1,000,000.
- **Key fields**: `block_timestamp`, `pool_address`, `asset0_address`, `asset1_address`, `fee_tier`

### Component B: Daily first appearance determination

- **Purpose**: Determine the exact date when each unique pool first became available.
- **Logic**: The minimum timestamp truncated to the daily level is calculated for each unique pool address, partitioned by chain and product. Each pool is thereby restricted to a single count on its initial creation date.
- **Key fields**: `timestamp`, `pool_address`, `chain`

### Component C: Cumulative tradeable pairs aggregation

- **Purpose**: Calculate the running total of tradeable pairs over time.
- **Logic**: The distinct count of new pools is aggregated on a daily basis for each chain. Missing days in the time series are populated with zero values to maintain a continuous daily record. A cumulative sum of the daily new pool counts is then calculated sequentially over time for each chain to represent the total number of tradeable pairs available on any given day.
- **Key fields**: `timestamp`, `tradeable_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.
