# Trade count Methodology

## Overview

Trade count measures the number of trades executed on a decentralized exchange. It shows how frequently users are buying or selling assets through the project.

## Data sources

- Smart contract events and program instructions generated during swap and trade activities
- Off-chain API endpoints for order book metrics
- Asset metadata for trading pair identification

## Common calculation approaches

### Automated market maker (AMM) swap tracking
For automated market makers, trade counts are obtained by summing swap events or program instructions. For example, `Swap` events are extracted from pool contracts across Uniswap and PancakeSwap, while swap instructions are captured from programs on Meteora.

### Order book fill tracking
For order book platforms, trade counts are derived from order fill events or API metrics. For instance, node fill events are captured from HyperCore infrastructure for tradeXYZ, while daily exchange metrics are ingested from APIs for Lighter.

**Note:** The calculation approaches and protocol examples above are representative patterns. Individual protocol implementations may vary.

Exchanges (DEX)

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

Aperture is a non-custodial DeFi exchange protocol built on Manta Pacific (originally a fork of Uniswap). Aperture was founded by Gao Han, Lian Zhu, and Peiqian Li in 2021.

Aperture team & investors own and govern the protocol. They do not currently take a cut of the total trading fees paid by traders (revenue). Aperture's investors include ParaFi Capital, Arrington XRP Capital, Costanoa Ventures and Divergence Ventures.
