DEX Volume's 9,260x Growth Brings New Crypto Challenges

Compared to seven years ago, the cryptocurrency sector has changed dramatically in size and scope. Trading volume on decentralized exchanges (DEX) surged approximately 9,260 times between 2019 and 2025, hitting a record $4.7 trillion. However, activity has cooled in 2026, with $1.63 trillion recorded so far this year.

This fragmentation is not limited to a single blockchain or sector. Liquidity is now spread across multiple blockchains, venue types, protocols, and execution settings, with no single one dominating.

SwapSpace has released its State of Crypto Swaps 2026 report, highlighting the scale of expansion. A key insight comes from the platform’s own data: more than 90.12% of its users interacted with multiple blockchain networks in 2026.

Meanwhile, survey participants did not view DEXs, CEXs, or aggregators as consistently providing the best rates.

These results indicate that the current market provides more execution choices, with no single venue, network, or liquidity source leading in all transactions.

90% of SwapSpace Users Are Multichain

As a crypto exchange aggregator, SwapSpace enables users to compare rates from various swap services and exchange cryptocurrencies via a single interface. This gives the platform a unique view into how users operate across different chains. Multichain activity among SwapSpace users is substantial. From 2022 to 2026, the proportion of users engaging with more than one blockchain varied between 72.50% and 93.66%.

The share hit a low of 72.50% in 2024, then climbed to 90.12% in 2026. Even at that low point, close to three-quarters of users were active on more than one blockchain.

These numbers offer a platform-level perspective on user behavior in a market where assets and liquidity are distributed among several networks.

A similar shift is visible in the wider DEX market. DeFiLlama data, referenced in the SwapSpace report, shows that Ethereum held 46.2% of global DEX volume in 2021, with BNB Chain accounting for 39.6%.

By 2025, Ethereum’s share had fallen to 19.3% and BNB Chain’s to 15.3%, while Solana made up 33.3% and other chains together accounted for 32.1%.

SwapSpace’s own activity data reveals no enduring market leader. Ethereum led platform activity from 2020 to 2024, Solana took the top spot in 2025, and BNB Chain was the leader in 2026.

Overall, the data indicates that multichain activity occurs in a market where liquidity leadership keeps shifting among ecosystems.

Fragmentation Does Not Stop at the Blockchain Level

The multichain trend represents just one aspect of fragmentation. Liquidity is also dispersed within individual blockchain ecosystems. According to the report, DeFiLlama tracks roughly 1,950 protocols on Ethereum, over 1,200 on BNB Chain, and more than 1,000 each on Arbitrum and Base.

These protocols may feature different pools, assets, and execution mechanisms. For instance, a user on Ethereum is not necessarily tapping into a single, unified liquidity environment.

This creates two layers of complexity: liquidity is spread across blockchain ecosystems and further divided among protocols and pools within each ecosystem.

This nuance is important because the number of possible execution routes can increase even without adding a new network. A trade may require not only selecting a chain but also navigating multiple liquidity sources within that chain.

Therefore, describing the market as merely 'multichain' downplays the extent of fragmentation at the execution layer itself.

DEX Growth Has Produced a Hybrid Market

DEX trading volume has risen steeply, but it has not supplanted centralized exchanges.

After hitting a record $4.7 trillion in 2025, DEX activity stays substantial in 2026 despite the broader crypto market slowdown. Centralized exchanges continue to dominate spot trading, while DEXs are making inroads in areas like perpetual futures.

This has produced a more hybrid market. Traders now shift between centralized and decentralized platforms based on liquidity, asset availability, trade size, and market conditions. Crypto trading is growing more fragmented instead of converging on a single dominant model.

Best Rate Still Matters — But It Is Not the Only Variable

Price remains a key factor in how users assess swaps. Using latent class analysis, SwapSpace estimates that 61.86% of survey respondents prioritized best rate, versus 52.51% for multichain access and 39.91% for support for rare tokens.

These differences are more pronounced across user segments. Crypto-native power users rated multichain access at 97%, best rate at 91%, and rare-token support at 87%. Traders and business users most valued best rate at 88%, with multichain access at 61% and rare-token support at 52%. Mainstream generalists were more evenly split, with 76% valuing both best rate and multichain access.

These numbers indicate that price remains important, but users can evaluate a trade across multiple dimensions simultaneously. The quoted rate may be considered together with access to a specific network or asset.

Similar uncertainty arises when respondents are asked which type of venue provides the best rates based on their experience. Responses were spread among DEXs, CEXs, aggregators, and 'depends on the situation,' with no single category dominating.

SwapSpace’s provider data provides additional context. Of users who executed at least two exchanges, 70% chose a different liquidity provider for their subsequent transaction, while 30% used the same one.

The findings imply that 'best' may be specific to each transaction rather than a consistent attribute of any single venue or provider.

Swaps are Serving More Than Trading

The survey also indicates that crypto swaps occur in various contexts.

Among respondents, receiving funds and personal payments were the most frequently cited crypto use cases, followed by short-term and long-term trading, with business payments less common.

When asked about additional platform features they value, respondents ranked payments for goods and services highest, then cashback and automatic swaps. Fiat withdrawal, Telegram functionality, and lending and borrowing were rated lower.

Triggers for transactions were also varied. Sudden price movements and portfolio rebalancing were the top reasons for swaps, with news and emergency needs also cited, and influencer signals ranked lowest.

These results imply that the same exchange infrastructure can serve diverse purposes, from reacting to price changes and managing a portfolio to receiving funds or making payments.

This also means that execution requirements can vary between transactions. A trader responding to a sudden market movement may prioritize different factors than someone exchanging assets for a payment.

Intent-Based Execution Moves Complexity Behind the Interface

One developing solution to this fragmentation is intent-based execution.

Rather than selecting an exchange, blockchain, or trading path, users simply specify what they want to accomplish. Competing systems then find a way to execute the trade.

Platforms including UniswapX, 1inch Fusion, and NEAR Intents already employ variations of this model. As crypto liquidity spreads across more venues and networks, this approach could simplify trading by pushing routing decisions to the background.

The market can remain fragmented while the user experience becomes considerably simpler. However, this means more complexity must be managed behind the scenes.

Platforms may handle this complexity in different ways. Intent-based execution is one option, but not the only one. Ultimately, what matters is whether users can access the networks and liquidity they require without needing to handle the underlying complexity themselves.
