The OpenOcean Exchange V2, OpenOcean's latest DEX aggregator router, leverages a next-gen routing algorithm that supports multi-route aggregation from various liquidity sources ensuring the best swap rates across 40+ blockchains including EVM compatible chains and non-EVM chains in DeFi. The OpenOcean aggregator router requires users to give permission to spend the specific amount of crypto assets they wish to trade. Once the tokens are successfully approved, users can execute the swaps and are guaranteed to receive the maximum token amount in return within the slippage they set.
OpenOcean's gasless swaps simplify DeFi trading by making it faster, more accessible, especially for those trading across multiple chains or new to the space. With gasless swaps, users benefit from fast settlement, secured by Permit2, and built-in MEV protection. Based on Uniswap's Permit2 standards, gasless swaps allow secure token approvals without extra on-chain transactions - users only need to sign and swap. Additionally, users don’t need native tokens like ETH or BNB for gas fees; the gas cost is abstracted and covered as part of the transaction.
If you are building DeFi products, trading bots, or arbitrage strategies on top of OpenOcean Exchange V2, you can easily monetize your flow using our built-in referral system. The router supports referral parameters /referrer and /referrerFee, which can be added directly to the request URL to apply an additional fee.
The referrer parameter is simply an EOA address that you control, making it straightforward to manage. With this setup, you can track your swap activity via OpenOcean analytics dashboard. This allows developers and integrators to generate passive income from DeFi trades while leveraging OpenOcean’s next-generation DEX aggregation infrastructure.
