Decentralized exchanges took more than 24% of spot cryptocurrency trading volume in July, marking the first time on-chain venues have crossed that threshold, according to data cited by The Block. The figure highlights a steady gain for DEXs relative to centralized platforms over the past year.
The shift came as overall spot trading activity weakened sharply. Total spot exchange volume fell to $670 billion, the lowest level in 12 months and far below a prior peak of $2.23 trillion, while centralized exchanges absorbed most of the decline.
DEXs narrow the gap with centralized venues
The Block said the ratio of DEX to CEX spot trading volume climbed to a record 24% in July, up from 17% a year earlier. The measure focused on spot transactions on major decentralized exchanges including Uniswap and Aerodrome, and excluded futures and other derivatives activity.
That increase means decentralized venues are taking a larger slice of a market long dominated by centralized exchanges. While CEXs still handle most spot activity, the latest reading shows the gap has continued to tighten as on-chain trading becomes a more established part of crypto market structure.
Centralized exchange weakness drove much of the change
The rise in DEX market share was attributed mainly to shrinking spot volumes on centralized exchanges rather than a broad rebound in overall trading. According to The Block, spot activity on CEXs dropped sharply, pushing the combined market down to its weakest monthly level in the past year.
The report also linked the downturn in centralized trading to job cuts at Coinbase and Gemini. In that environment, a growing share of traders moved toward on-chain alternatives, helping decentralized platforms gain ground even as the total market contracted.
Execution and infrastructure improvements supported DEX adoption
The Block said technical changes on decentralized exchanges also contributed to the stronger showing. Improvements in liquidity aggregation and faster cross-chain swaps were cited as factors that helped DEXs expand their role in spot trading.
Those upgrades appear to have reduced one of the main advantages previously associated with centralized exchanges: faster execution. As that speed gap narrowed, decentralized venues were better positioned to capture activity from traders looking for on-chain options.
What the July data indicates next
The July reading does not suggest that decentralized exchanges have overtaken centralized platforms, but it does mark a new high-water mark for DEX participation in spot markets. The key confirmed development is that DEXs gained share during a period when centralized trading volumes were under pressure.
The next important signal will be whether DEXs can hold or extend that share if spot market activity recovers from the 12-month low. For now, the reported figures point to a market where centralized exchanges remain larger overall, but where decentralized competitors are steadily becoming harder to ignore.
