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.

# Uniswap Tradeable assets Methodology

## 1. Overview

The number of unique assets available for trading on Uniswap is measured by the Tradeable assets metric. The breadth of asset coverage across Uniswap V2, Uniswap V3, and Uniswap V4 is reflected by this metric. A cumulative count of unique assets is maintained by identifying the first time an asset is initialized in any trading pool or pair. A clear indication of the protocol's liquidity depth and asset diversity over time is provided by this metric.

## 2. Data sources

- **Blockchain events**: `PairCreated` events from `Factory` contracts for Uniswap V2, `PoolCreated` events from `Factory` contracts for Uniswap V3, and `Initialize` events from `PoolManager` contracts for Uniswap V4, covering Ethereum, Arbitrum, Optimism, Base, and 11 other chains

## 3. Step-by-step calculation

### Component A: Uniswap V2 and Uniswap V3 asset extraction

- **Purpose**: To extract unique asset addresses from Uniswap V2 and Uniswap V3 pool creation events
- **Logic**: `PairCreated` events from Uniswap V2 `Factory` contracts and `PoolCreated` events from Uniswap V3 `Factory` contracts are parsed. The addresses for both assets in each pair (`token0` and `token1`) are extracted along with the block timestamp. For Uniswap V3 on Optimism, historical pre-regenesis pool creations are also included from seed data.
- **Key fields**: `token0_address`, `token1_address`, `block_timestamp`

### Component B: Uniswap V4 asset extraction

- **Purpose**: To extract unique asset addresses from Uniswap V4 pool initialization events
- **Logic**: `Initialize` events from Uniswap V4 `PoolManager` contracts are parsed to extract the initialized asset addresses (`currency0` and `currency1`). If either asset address is identified as a null address, it is replaced with the corresponding wrapped native asset address.
- **Key fields**: `token0_address`, `token1_address`, `block_timestamp`

### Component C: First appearance tracking

- **Purpose**: To identify the timestamp when each unique asset was first introduced to the protocol
- **Logic**: The extracted asset addresses from Uniswap V2, Uniswap V3, and Uniswap V4 are combined. For each unique asset address, the minimum block timestamp across all pools or pairs is determined per chain and product. This timestamp is truncated to daily granularity to establish the first appearance date of each asset.
- **Key fields**: `token_address`, `block_timestamp`

### Component D: Cumulative aggregation

- **Purpose**: To calculate the running total of tradeable assets over time
- **Logic**: The number of new unique assets appearing for the first time is aggregated by day, chain, and product. A cumulative sum of these daily new asset counts is calculated chronologically to represent the total number of tradeable assets available on any given day. Zero values are assigned to days with no new asset deployments to maintain a continuous daily time series.
- **Key fields**: `tradeable_assets`, `timestamp`
