A DEX integration lets your application, wallet or bot swap tokens on decentralised exchanges such as Uniswap, Curve, PancakeSwap or, on Solana, through Jupiter. The swap itself is one transaction, but a good integration also gets the price right, protects the user against bad fills and handles everything that can go wrong between quote and confirmation.
Direct Router or Aggregator?
- Direct integration with one protocol's router or pool contracts gives full control and no third-party dependency. Suitable when you trade a known set of pairs, or need custom logic such as hooks on Uniswap v4.
- Aggregators such as 1inch, 0x, ParaSwap or Jupiter split orders across many pools for a better price. Faster to integrate and usually better prices for arbitrary pairs, at the cost of an external API.
Many products combine both: an aggregator for general swaps and direct routes where speed or control matters.
What a Solid Swap Flow Includes
- Quote with price impact and expected output, refreshed while the user decides.
- Approval: classic ERC-20 approvals, or signature-based approvals with Permit and Permit2 to save a transaction.
- Slippage and deadline limits, so a moving market cannot fill the order at any price.
- Simulation before sending, to catch reverts, fee-on-transfer tokens and insufficient balances.
- MEV protection through private submission where available.
- Confirmation and reconciliation: reading the actual received amount from the receipt, not assuming the quote.
Multi-Chain and Fees
Each chain has its own DEXs, gas model and token lists. We handle chain-specific routing, native token wrapping, gas estimation (including layer 2 data fees) and, if your business model needs it, a transparent integrator fee on swaps. For cross-chain swaps see cross-chain bridges.
Frequently Asked Questions
Which DEXs can you integrate?
Any DEX with public contracts or an API, on EVM chains and Solana. Through aggregators, hundreds of liquidity sources become available at once.
Can we earn fees on swaps?
Yes. Most aggregators and routers support an integrator fee, shown transparently to the user.
How do you protect users from bad prices?
With price impact warnings, slippage limits, deadlines, simulation and, where available, private transaction submission.
Who owns the code?
Ownership of the source code is set out in the contract, and the code can be fully yours, including documentation and tests.
