Centralized exchanges act more like traditional financial institutions by being the intermediaries that hold the user’s funds in custody and facilitating trades through an order book system. Their advantage is that they offer high liquidity, user friendly interfaces and support fiat on and offramps. This makes them highly accessible to beginners. However, they require users to undergo KYC and AML, and as a user, you cede control of your assets to the exchange. This introduces counterparty risk and susceptibility to hacks and censorship. Decentralized exchanges on the other hand are built on the blockchain and they enable peer to peer trading directly from users wallets via smart contracts. This means that users retain full custody of their assets, eliminating the need for an intermediary.
Decentralized exchanges are celebrated for their privacy, censorship resistance and direct access to the burgeoning DeFi ecosystem. Historically, the main challenges of DEXes are lower liquidity, complex user interfaces and higher transaction fees, but does it remain that way? Let’s dissect the topic and explore the battle between DEXes and CEXes.
The crossover looms, but why is DEX volume surging
There are many reasons why DEX volume keeps surging. It all began with high profile incidents like the collapse of FTX in late 2022. This collapse and related incidents severely eroded trust in centralized platforms and pushed users towards self custody solutions offered by DEXes. This was not helped by the rapid evolution of DeFi which has created a diverse ecosystem of financial products. These financial products like yield farming, staking, lending and perpetual futures are often exclusive to DEXes. When we combine such offerings with the DEX platforms serving as primary listing venues for new and early stage tokens, it attracts retail traders who seek alphas in addition to the safety of self custody. And as new people come in to trade in DEXes, the volumes will naturally shoot up.
People are also rushing over to DEXes because they brought improved user experience and aggregation. DEXes are becoming more sophisticated bringing better user interfaces, DEX aggregators like 1inch that find optimal trade routes across multiple platforms and wallet native features. In recent months, the DEX to CEX spot trading volume ratio has seen remarkable growth. After hitting 20% in January 2025, it peaked as an all time high of 37.4% in June 2025 before stabilizing around 21% by November 2025. Perpetual futures trading on DEXes has also seen a significant increase with its ratio to CEX perpetuals reaching an all time high of 11.7% in November 2025. This demonstrated growing confidence in chain derivatives on DEXes.
Fusaka’s role in making decentralized trading faster and cheaper
Previously, despite Layer 2 (L2) solutions significantly reducing Ethereum transaction fees after the Dencun upgrade of March 2024 L2s were already experiencing peak usage and limited blob space for posting transaction data back to mainnet. And all this led to persistent, albeit lower costs and potential congestion. Now, the Fusaka upgrade of December 3, 2025 was a hard fork which is a pivotal upgrade designed to address these core scaling issues. And all this directly benefits DEXes built on or leveraging Ethereum’s L2 ecosystem.
Fusaka’s PeerDAS upgrade is a key innovation that allows validators to verify small fragments of data instead of downloading entire data blobs from L2s. This dramatically increases data throughput capacity and significantly reduces bandwidth requirements. Due to the Fusaka upgrade, retail traders can expect 40 to 60% lower transaction costs on L2 networks. This is due to the increased data availability and reduced blob fees. Fusaka also set the stage for the entire Ethereum L2 ecosystem to handle over 100K transactions per second. This transforms Ethereum into a network that is capable of sustaining massive ecosystem scaling solutions. The benefits of Fusaka do not only affect the L2 but also the L1 layer. It more than doubles the L1 gas limit boosting L1 throughput to an estimated 12000 transactions per second.
Now, it is important to note that this upgrade had a direct impact on the operations of DEXes. By drastically lowering fees and increasing transaction speeds, Fusaka directly tackles the two most significant pain points of using DEXes. This makes them more attractive and more competitive alternatives to CEXes.
The real meaning of volume flip for retail traders
Cheaper and faster transactions open up DEXes to a broader audience, and therefore the DEXes become more practical for smalltrades amd frequent activity. The volume flip means that traders gain unprecedented control over their assets and greater financial autonomy. It also means that retail traders will have easier and more affordable access to a wider array of tokens including obscure or nascent projects that often launch on decentralized platforms first.
While offering opportunities like participation in diverse DeFi protocols, this shift also demands a greater personal responsibility for securing private keys and understanding the nuances of smart contract interactions. Smart contract interactions carry inherent risks that may also lead to impermanent losses.
I take the competition between DEXes and CEXes as a key driver of innovation. The competition is a healthy one which pushes both types of exchanges to offer better services, lower fees and improved user experiences. This can potentially lead to hybrid models that combine the best of both the DEX and CEX worlds.
Final thoughts and conclusion
The volume flip is no longer a distant dream as it has become an increasingly plausible reality. Fueled by growing demand for self custody, relentless innovation within DeFi and transformative scaling upgrades like Ethereum’s Fusaka, DEXes are poised to capture a dominant share of the crypto trading markets. However, there are still challenges about user experience and regulatory clarity that persist. While these challenges need to be addressed, the trajectory points towards a future where decentralized trading becomes the norm. This offers retail traders a more transparent, secure and financially autonomous experience.
