Dex Volume Exploded Over 9,000X. Now Crypto Has A New Problem

What Happened

SwapSpace recently published its State of Crypto Swaps 2026 report, which shows the massive extent of this growth. One of the clearest findings comes from its own platform data. Over 90.12% of its users interacted with more than one blockchain network in 2026.

At the same time, survey respondents did not identify DEXs, CEXs, or aggregators as universally offering the best rates.

90% of SwapSpace Users Are Multichain

Market Context

The crypto industry today is almost unrecognizable from 7 years ago, both in size and scale. Just for decentralized exchanges (DEX), trading volume grew roughly 9,260x from 2019 to a record $4.7 trillion in 2025. In 2026, however, activity moderated to $1.63 trillion year-to-date.

It’s not down to one chain or sector. Liquidity is now distributed across more blockchains, venue types, protocols, and execution environments, without one clearly replacing the others.

The findings clearly show that the market today offers more execution options, and no single venue, network, or liquidity source dominates every transaction.

These figures provide a platform-level view of how users operate in a market where assets and liquidity are spread across multiple networks.

The broader DEX market shows a similar redistribution of activity. According to DeFiLlama data cited in the SwapSpace report, Ethereum accounted for 46.2% of global DEX volume in 2021, while BNB Chain represented another 39.6%.

Taken together, the data shows that multichain activity is taking place in a market where liquidity leadership continues to shift between ecosystems.

The multichain picture captures only one layer of fragmentation. Liquidity is also distributed within individual blockchain ecosystems. The report cites DeFiLlama tracking of around 1,950 protocols on Ethereum, more than 1,200 on BNB Chain, and more than 1,000 each on Arbitrum and Base.

Those protocols can contain different pools, assets, and execution mechanisms. A user operating on Ethereum, for example, is not necessarily accessing one unified liquidity environment.

That creates two layers of complexity: liquidity is distributed between blockchain ecosystems and again between protocols and pools within them.

The distinction matters because the number of possible execution paths can expand even without adding another network. A transaction may involve not only choosing a chain, but also navigating several potential sources of liquidity within that chain.

In that sense, describing the market as simply “multichain” understates how fragmented the execution layer itself has become.

DEX Growth Has Produced a Hybrid Market

DEX trading has grown sharply, but it has not replaced centralized exchanges.

After reaching a record $4.7 trillion in 2025, DEX activity remains significant in 2026, even as the broader crypto market has cooled. Centralized exchanges still handle most spot trading, while DEXs are gaining ground in areas such as perpetual futures.

The result is a more hybrid market. Traders now move between centralized and decentralized venues depending on liquidity, asset availability, transaction size, and market conditions. Crypto trading is becoming more fragmented rather than shifting toward one dominant model.

Why It Matters

SwapSpace is a crypto exchange aggregator that lets users compare rates across different swap services and exchange different crypto through a single interface. So, the platform has a notable vantage point of how users today interact across different chains. Among SwapSpace users, multichain activity is not marginal. Between 2022 and 2026, the share of users interacting with more than one network ranged from 72.50% to 93.66%.

It reached its lowest point at 72.50% in 2024, before rising to 90.12% in 2026. Even at the low point of the observed period, nearly three-quarters of users interacted with more than one blockchain.

Details

By 2025, Ethereum’s share was 19.3% and BNB Chain’s 15.3%, while Solana accounted for 33.3% and other chains collectively represented 32.1%.

SwapSpace’s internal activity data shows a similar lack of a permanent leader. Ethereum led platform activity from 2020 through 2024, Solana moved into first place in 2025, and BNB Chain led in 2026.
