DEX volume market share is a useful way to see where trading activity is concentrating, but it is not the same thing as liquidity depth, user quality, or sustainable protocol revenue. This page keeps the question narrow: which protocols and selected chains are taking share in provider-normalized DEX volume.
Quick answer
Use protocol share to understand venue competition, then use chain share to understand where DEX activity is happening. The charts can show volume concentration and rotation, but they cannot prove organic demand, low slippage, profitability, or the absence of incentive-driven volume.
DEX volume share by protocol
Use this chart to compare selected DEX protocol share over the preview window. The metric is daily protocol volume divided by total DefiLlama DEX daily volume, with selected protocols aggregated by brand and the remainder grouped as Others.
Protocol share is the venue battlefield. It helps show whether volume is concentrated in a few dominant DEX brands or spread across a long tail of venues.
Volume share is not liquidity depth, slippage, revenue, or organic user quality. Incentives, wash volume, chain mix, and routing behavior can all affect the number.
DEX volume share by selected chain
Use this chart to compare selected-chain DEX volume share across Ethereum, Solana, Base, and Arbitrum. The denominator is the sum of DEX volume across this selected chain set, not the full crypto market.
Chain share adds the location layer. If protocol share tells you which DEX brands are active, chain share tells you which ecosystems are hosting the selected DEX activity.
This is a selected-chain denominator. It excludes CEX volume, liquidity depth, slippage, user retention, and chains outside Ethereum, Solana, Base, and Arbitrum.
How to read DEX share like a market map
The protocol chart answers who is winning venue share. The chain chart answers where selected-chain DEX volume is concentrating. Reading them together is more useful than reading either alone because a protocol can grow by chain expansion, routing behavior, or category-specific demand.
What this page can support
This page can support statements about DefiLlama-reported DEX volume share by selected protocol and selected chain. It can identify visible concentration, rotation, and denominator limits.
What needs another chart
Liquidity quality needs order-book or pool-depth evidence. Organic demand needs user, retention, incentive, or wash-volume checks. Revenue quality needs fees and fee-capture evidence. Those are separate chart families, not automatic conclusions from volume share.
Methodology
The charts use DefiLlama DEX volume data. Protocol share divides daily protocol volume by total DefiLlama DEX daily volume. Selected-chain share divides each selected chain's DEX volume by the sum of Ethereum, Solana, Base, and Arbitrum DEX volume. Both charts should be read as descriptive volume evidence, not a complete market-quality score.
