DEX Aggregator Backend for Cross-Chain Swaps and Multi-Chain Liquidity Routing
Challenge
A DEX aggregator startup needed backend infrastructure for on-chain and cross-chain swaps across thousands of tokens.
The main challenge was liquidity fragmentation. No single swap provider could deliver the best coverage, pricing, routing, and execution conditions across every chain, token pair, and trade size.
The backend also had to handle inconsistent provider data. Each swap API returned different formats for:
- Quotes
- Fees
- Token metadata
- Network data
- Transaction parameters
- Route details
- Price information
The client needed one stable integration layer that could support multiple liquidity sources, reduce dependency on a single provider, and keep future swap API integrations easier to add.

Solution
Aetsoft developed a DEX aggregator backend that unified 8 swap providers inside one system.
The backend normalized provider-specific responses into a single swap data structure. This gave the client one consistent layer for quote requests, routing logic, transaction preparation, and provider comparison.
Core functionality included:
- Integration of 8 swap providers
- Same-chain swap support
- Cross-chain swap support
- Unified quote processing
- Normalized transaction data
- Liquidity source aggregation
- Provider response standardization
- Route and fee handling
- Token metadata processing
Aetsoft also built a token data layer for token lists, prices, logos, network details, filtering logic, and asset metadata from multiple sources.
This created cleaner asset discovery for users and made the product easier to expand as new chains, tokens, and swap APIs were added.

Results
The client received a scalable DEX aggregator backend with broader liquidity coverage and a cleaner integration model.
The solution helped the startup:
- Connect 8 swap providers through one backend
- Support on-chain and cross-chain swaps
- Reduce dependency on a single liquidity provider
- Standardize quotes, routes, fees, and transaction data
- Improve token data quality across multiple sources
- Prepare transaction-ready swap data for the frontend
- Add future swap providers with less backend rework
The platform gave the client a stronger foundation for decentralized exchange aggregation, multi-chain liquidity routing, cross-chain swap execution, DeFi backend infrastructure, swap API integration, token data management, blockchain integration, and scalable DEX product development.
