DEX-to-CEX ratio

Jul 30, 2025 | Updated Jul 30, 2025

The DEX-to-CEX ratio measures the proportion of crypto trading volume occurring on decentralized exchanges compared to centralized exchanges.

What Is the DEX-to-CEX Ratio?

The DEX-to-CEX ratio represents the percentage of total cryptocurrency spot trading volume that occurs on decentralized exchanges (DEXs) relative to centralized exchanges (CEXs). This metric is calculated by dividing monthly decentralized exchange volume by centralized exchange volume, expressed as a percentage.

The ratio serves as a key indicator of the crypto market’s shift toward decentralized trading platforms. A higher ratio suggests growing adoption of DEXs, while a lower ratio indicates dominance of centralized platforms.

This measurement has gained significance as DEXs have evolved from niche platforms to major competitors to CEXs in the cryptocurrency trading landscape. The ratio helps traders, analysts, and industry observers understand changing user preferences and the broader trend toward decentralized finance (DeFi) adoption.

How Does the DEX-to-CEX Ratio Work?

First, raw trading volume data is collected from established CEXs and DEXs. For DEXs, this includes platforms like Uniswap, SushiSwap, PancakeSwap, and Raydium. For CEXs, it encompasses established platforms such as Binance, Coinbase, Kraken, and other major centralized trading venues.

Next, the data is filtered to remove wash trading, bot activity, and flash trades that could artificially inflate volume figures. Finally, the total verified DEX volume is divided by the total verified CEX volume and multiplied by 100 to express the result as a percentage.

For example, if DEXs processed $100 billion in monthly trading volume while CEXs processed $900 billion, the DEX-to-CEX ratio would be approximately 11.1%. This metric is typically calculated monthly to smooth out daily volatility and provide meaningful trend analysis.

Several factors influence the ratio’s movement:

Growing DEX Adoption – occurs when users seek self-custody, enhanced privacy, or access to newer tokens not yet listed on centralized platforms.

Improved DEX Infrastructure – Better liquidity provisioning, reduced transaction fees through Layer 2 solutions, and more intuitive interfaces make DEXs more accessible to a wider base of users.

Regulatory Pressures – As governments implement stricter compliance requirements, some traders migrate to DEXs that operate without central authorities.

The ratio reached significant milestones in recent years, with some reports indicating it has approached or exceeded 20% during peak periods. This represents substantial growth from earlier years when DEX volume represented less than 5% of total crypto trading activity.
