DEX infrastructure
by business model
On-chain trading creates new opportunities across financial products. We tailor infrastructure to match how each platform grows and competes.
For centralized exchanges
CEX-DEX hybrid
exchange
Over the past few years, the DEX-to-CEX ratio has grown from <1% of spot volume in 2021 to over 20% in 2025. As the crypto market matures, there’s a growing demand for deeper liquidity access and more efficient execution.
Swaps are the most efficient way to trade long-tail tokens. For a growing number of users, centralized exchanges remain the entry point, but they turn to on-chain swaps when they want access to new tokens. Coins typically appear on DEXs 2-8 weeks before centralized listings.
If an exchange does not offer swaps, a growing number of users will simply move to competitors. Without swaps, a centralized exchange can be reduced to an on/off ramp tool.
- Reach new tokens coins weeks before CEX listings
- Keep the users in your trading ecosystem
- Reduce dependence on external liquidity
For fintech & banking
Controlled DeFi access
for fintech
A regular DEX will not fit a regulated fintech product. Standard DEX architecture leaves too much outside institutional control, thus it’s not applicable in fintech or banking.
In 2026, crypto is in much clearer regulatory boundaries. In the EU, MiCA is now fully applicable, which means regulated businesses must have transaction oversight. Other jurisdictions also roll out crypto frameworks, including the UK, Singapore, and Hong Kong.
As a result, fintechs either limit their crypto offering or lose users to unregulated third-party DEXs. But this does not mean fintechs have to give up on crypto. On the contrary, they can keep growing.
- Offer on-chain trading under institutional control
- Keep users inside your product environment
- Reduce dependence on third-party DEX infrastructure
For DEX protocols and aggregators
DEX infrastructure
upgrade
Launching a DEX is easier than building one that stays competitive. It makes sense to launch quickly on top of third-party routing, but that model doesn’t scale because every trade comes with intermediary fees.
If a platform cannot maintain competitive pricing and stable execution, users move elsewhere.
- Improve trade quality and pricing consistency
- Reduce dependence on third-party liquidity providers
- Keep more margin inside your platform
Case studies
In decentralized trading, infrastructure determines who keeps the margin and who loses the user. These case studies show how platforms strengthened their trading economics.
Our impact
on the DEX market
DEX platform development
001
Doubled the margins of a DEX aggregator
Our client was a DEX aggregator that shared half of their margins with infrastructure providers. As any startup, their first goal was to launch quickly, so they plugged several DEXs via API and aggregated the rates.
But third party infrastructure comes with a price. They had to share effectively half of their margins with the underlying exchanges.
The client wanted to cut out the middlemen that didn’t let them scale. We built a routing engine connected to hundreds of liquidity pools, with path optimization and trade splitting across available sources.
The platform now has much stronger trading economics. They offer much lower fees while almost doubling their margin.

DEX/CEX integration
003
A centralized exchange added swaps with a clear CeFi-DeFI boundary
The CEX could not list new tokens as fast as users wanted to trade them. More of that demand was moving to decentralized exchanges, where assets appeared 2-8 weeks earlier.
The client wanted to expand token access far beyond manual CEX listings – thousands of new liquid assets should become automatically available through DEX infrastructure. Our goal was to offer DEX swaps in the same app, but we needed to draw a clear boundary between the regulated CEX and decentralized trading.
We added automatic wallet creation and embedded on-chain swaps. Users could access DeFi trading without leaving the app, but a separate wallet layer preserved the boundary between centralized trading and DeFi swaps. The platform is now stronger than ever.
Fintech swap integration
004
Thousands of new payment options for a regulated PSP
The client is a payment provider. We had already built their fiat and crypto payment aggregation layer, but their payment infrastructure only supported major tokens like BTC and ETH. The next step was to expand far beyond standard coins.
We needed to add thousands of tokens, so customers could pay with virtually anything. Plus, the tokens are automatically converted at the best available rate. Merchants can settle in stablecoins without ever holding volatile assets.
Now customers have more payment options than was ever possible. Our system combines multiple fiat and crypto liquidity providers, so each merchant can match their risk profile and payment model.

Frequently asked
questions about DEX
development services
-
What is DEX development?
Decentralized exchange development means building the infrastructure behind on-chain trading. That includes the smart contracts, routing logic, liquidity connections, wallet flows, transaction handling, and the product layer users actually interact with. In practice, a serious DEX build is not just a swap interface. It is a trading system that has to work under real conditions and real execution pressure.
-
Do you build AMMs, aggregators, or order book DEXs?
Yes, depending on the product model. AMMs work when liquidity sits in pools and the goal is straightforward on-chain trading. Aggregators make sense when pricing needs to be sourced from multiple venues and routes need to be optimized across them. Order book or more custom execution models are possible too, but they only make sense when the product really needs that trading logic and has a good reason not to rely on pools.
-
Do you offer white-label DEX development?
We can build on top of existing components when speed matters, but a serious DEX development company would offer custom work. White-label helps launch faster and can be enough for a basic product. Custom decentralized exchange software development is usually needed when the platform has to compete on pricing, execution quality, margin, wallet experience, or compliance. The more important the business model is, the less likely a basic white-label setup will be enough.
-
Which chains do you support?
We work with multi-chain setups. Chain choice depends on where the liquidity is, what assets need to be supported, how expensive transactions can be, how fast execution needs to be, and whether the product requires bridging or cross-chain swaps. In most cases, the right answer is not to support as many chains as possible, but to support the chains that make sense for liquidity, users, and operating model.
-
Can you build cross-chain swaps?
Yes. Cross-chain support is possible, but it adds real complexity around routing, bridging, execution risk, monitoring, and failure handling. It should be added only when the product actually benefits from it. In some cases, multi-chain support expands asset coverage. In others, it adds more operational complexity than value. That is why it has to be designed around the use case, not added just because it sounds broader.
-
Do you handle smart contracts, backend, and frontend?
Yes. A DEX product usually needs all three. Smart contracts handle the on-chain logic. Backend services handle routing, simulations, monitoring, transaction management, and operational logic. Frontend is what users trade through. In many cases, wallet infrastructure is also part of the build, because the wallet layer changes how the product actually works for users.
-
Do you build wallet infrastructure too?
Yes. That can include non-custodial wallets, custodial setups, embedded wallets, gas abstraction, and policy controls. Wallet design matters because it defines how users sign, fund, and complete trades. In many decentralized exchange development services, the wallet layer is one of the main factors behind user friction, control, and conversion.
-
How do you handle liquidity?
Liquidity is a core part of any exchange. We connect to pools, aggregators, market makers, or other sources depending on the product. The goal is not just access to liquidity in theory, but access at pricing and execution quality that make sense for the platform. An exchange can have liquidity connections and still perform badly if routing is weak or spreads are not competitive.
-
Do you build your own routing logic?
Both are possible. Some products launch on third-party routing because it is faster and reduces time to market. But if routing fees are too high, control is too limited, or execution quality is too inconsistent, internal routing becomes the better long-term model. Custom routing usually makes sense when the platform wants more control over margins, pricing logic, and how trades are executed across liquidity sources.
-
Can you add swap functionality to an existing product?
Yes. That is one of the most common cases. We work with exchanges, fintechs, and payment products that want to add on-chain swaps, broader token coverage, or embedded DeFi functionality without rebuilding everything from scratch. The key part is making the new trading flow fit the existing product instead of forcing users into a separate crypto-native experience.
-
Can regulated businesses use DEX infrastructure?
Yes, but usually not in the same way as a crypto-native app. Standard DEX flows leave too much outside institutional control. Regulated products usually need embedded wallets, governed execution, monitoring, policy logic, and a clearer compliance boundary. The issue is not whether regulated businesses can use on-chain trading, but how thaat trading is structured inside the product.
