As we start to see renewed interest in crypto—with prices hovering near their all-time highs and prominent people and institutions discussing the industry—building a robust crypto exchange is essential.

Crypto traders’ standards for an exchange are higher than ever. They are looking for a sleek user experience, architecture that supports high throughput and low latency, and top-notch security. The latter is especially important given the industry is still recovering from the implosion of FTX and the domino effect it had on other businesses in the space. 

While centralized exchanges excel at building beautiful user interfaces and intuitive user experiences, they operate at speed by custodying users’ funds for them. As the industry has seen many times throughout crypto’s history, funds that the users themselves don’t control can be mismanaged by fraudulent actors. Additionally, CEXs possess the authority to limit access to accounts, such as freezing funds or halting withdrawals. As the crypto adage goes: Not your keys, not your coins. 

Decentralized exchanges, on the other hand, grant users complete control over their funds with self-custody. They leverage blockchain technology and smart contracts to execute trustless trade and settlement. However, this architecture can be clunky and complex for users to navigate. It comes with trade-offs in throughput and latency, the absence of advanced trading features (like advanced order types and conditions), and can also deal out significant fees to pay gas for settlement on a blockchain. 

A new crop of crypto entrepreneurs is thinking about exchange architecture differently. They are looking to combine aspects of a centralized and decentralized exchange with building on the best of both worlds. Enter hybrid crypto exchange. 

A better trading engine for a better crypto trader

CEXs from the last cycle, including Coinbase and Binance, built their businesses by copying the UI of broker platforms and mimicking the mechanics of broker platforms and the UI of fintech apps. They focused on user-friendly UI, robust mobile apps, competitive fees, and an extensive selection of coins and tokens. 

The centralized trading infrastructure offers high throughput and low latency, which is what the world demands for crypto trading. Going deeper, high throughput and low latency enable better liquidity, as market makers can reprice quicker. They also allow for more efficient margin usage, as a centralized risk engine enables the exchange to offer higher leverage. Centralization enables advanced trading features and logic, such as advanced order types and conditions. 

Aside from performance, it allows exchanges to have more control over compliance. CEXs control what customers have access to their platform and can manage the access of those users by implementing robust blockchain analysis, fincrime, and compliance programs. In the wake of FTX, lawmakers and enforcement agencies have been clamping down on the industry, dishing out huge fees and even jail time to businesses and entrepreneurs that are found to be skirting regulations. 

So, to sum up, that’s why the hybrid exchange model inherits the bright side of centralization. The trading architecture is kept centralized to a large extent. UX is also inherited from CEX because DEXs simply lack features, such as simple account creation, which eliminates the need for users to already have a wallet before interacting with the exchange. DEXes are also limited in their on- and off-ramps, fee abstraction, and advanced trading analytics. Especially as another batch of crypto traders enters the space during what appears to be the beginning of a bull run, a powerful feature set on top of a polished user experience is critical. 

It all sounds like a flawless victory for centralization so far. The question is, what do hybrid exchanges inherit from decentralized ones? The answer is simple: The essential feature that enables trust in crypto trading. And centralization has a dark side.  

Give users the keys

Hybrid exchanges still pull from DEX concepts by utilizing blockchain technology to secure funds. Users self-custody their funds, and trades are settled on the blockchain at various periods. Another crucial trait is the on-chain validation of the trading logic, which will prevent operator fraud. As such, trust is provable, and transparency is immutable. 

Operator fraud is one of the most significant risks in crypto. CEX’s control over funds is beneficial for compliance reasons; however, it grants the authority to limit access to accounts, such as freezing funds or halting withdrawals. The collapse of FTX certainly heightened concerns over an operator’s access to user funds. Yet, FTX wasn’t the first or only exchange to mishandle user funds and call into question the CEX model. One of the first-ever crypto exchanges, MtGox, completely shut down and filed for bankruptcy in early 2014 because of an undetected theft over many years that drained the exchange of more than 850,000 Bitcoin (BTC). In 2018, Canadian exchange QuadrigaCX went dark and was later revealed to be a Ponzi scheme, causing the loss of roughly $190 million in user funds. 

These continued instances highlight the importance of self-custody and trustless on-chain settlement, whereby users hold the keys to their own coins instead of trusting a centralized entity that isn’t fully transparent to retain their keys. 

Scaling tech for cutting costs

In the derivatives market, traders often transact in large volumes, which can accrue significant fees. There is no feeless trading. CEXs and DEXs charge fees for trading, but DEX users have an additional cost to settle all their trades on a blockchain. These fees fluctuate depending on the overall usage of the blockchain at any given period. Earlier this year, in March, Ethereum transaction costs skyrocketed to nearly a two-year high due to increased speculation in meme tokens.

The hybrid exchange approach simplifies the fee structure because trading is centralized and relies on layer-2 technology to boost scalability while keeping transaction fees low. Rollups are one such scalability solution that processes transactions on a separate network before bundling the transaction data into batches to submit and settle to the main chain. 

Now’s the time to go hybrid

Blending features from centralized and decentralized exchange architecture is an obvious choice in a market that’s becoming more mature and competitive. 

The speed, usability, and design of CEX help users of all levels of technical know-how trade crypto easily. And the security provided by implementing aspects of DEX will create an ecosystem of trust and reliability that gives users peace of mind. 

The hybrid crypto exchange is poised to be the winning business model in the next bull run, highlighting that it’s not always about reinventing the wheel as much as it’s about creatively putting the pieces together. It’s not a one-size-fits-all industry; it won’t have a one-size-fits-all solution.
