How does it work? Interport allows performing any kind of swap while finding the best rate for your transaction! It can be the same network ETH to USDT swap or Interchain swap from CRV on Polygon to AAVE on Binance Smart Chain. We still find the best possible rate and do it within one simple transaction for our users.
Our protocol swaps assets on the source chain into stables and adds these stables to the Interport liquidity pool on the same chain. A cross-chain call to our contract at the destination chain with parameters to execute is sent at the same time. The contract at the destination chain will pull stables from the Interport liquidity pool, perform swaps, and send desired tokens to the user on the desired chain.
There is absolutely no backend job or tasks performed on Interport's behalf. Everything is running on smart contracts and is transparent.
Best rate swaps We aggregate over 250 different sources such as liquidity pools, DEXes, price feeds, and even aggregators like 1inch and 0x. Interport makes sure users get the best possible rate on the given network by considering price impacts and slippage.
In case there is no concentrated liquidity for the specific token, Interport will make a partial swap on different sources and build it into one transaction. We suggest users always check opportunities at all networks the token is being traded as they may get a better deal.
Single swap transactions Interport has optimized the swap process to make it as simple as possible. Users don't have to confirm any transactions on the destination chain. All the fees are estimated in advance, as well as swap rates and slippage.
That allows us to minimize required actions for the user, as they will simply receive tokens on the desired chain. The logic and contracts are well-optimized to minimize fees, hence the execution of the swap and transfer happens within one transaction.
​
Swaps on the same network Interport also allows for a regular swap within one network, like any other DEX or aggregator. Our protocol uses the best rate model, sourcing liquidity sources from various providers. This builds the most efficient routing while diversifying the swap within several liquidity pools. This results in the lowest price impact and delivers the best rate.
​
Slippage optimization Interport introduces a unique approach to slippage configurations and settings. This allows us to minimize slippage losses and deliver even better swap rates.
Whenever a user chooses the slippage, we break slippage % into six different slippage zones for the destination chain. For example, 1% slippage would be broken into 0.0%, 0.2%, 0.4%, 0.6%, 0.8% and 1%.
Depending on the actual slippage on the origin network, the cross-chain message will be formed with the actual amount of swapped asset from the origin chain. Therefore the slippage of 1% is a potential maximum slippage in our case rather than an actual one. Actual slippage may be five times lower or even 0%.
