Interport Finance: what’s special?

How it works?

Interport is a decentralized exchange that allows you to perform Interchain swap (cross-chain swaps) at the best rate due to cross chain liquidity aggregation contracts that source over 250 dexes and liquidity sources looking for the best price! The protocol works with cross-chain messages to communicate with contracts on other chains and build the transaction, so user always knows the exact amount of desired tokens he will receive on another chain!

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 the Binance Smart Chain network. We still would find the best possible rate and do it within one simple transaction for the user.

Our protocol would swap assets on the source chain into stables and add these stables to the Interport liquidity pool on the same chain while sending a cross-chain call to our contract at the destination chain with parameters to execute. 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 Interports behalf. Everything is running on smart contracts and is super 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, 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 being estimated in advance, as well as swap rates, slippages etc.

That allows us to minimize required actions for the user, as they would 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.

Slippage optimization

Interport introduces a unique approach to slippage configuration and setting, which allows us to minimize slippage losses and hence deliver even better swap rates.

Whenever a user chooses the slippage, we are breaking 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 5 times lower or even 0%.

Interchain rates and swaps

With Interport you can swap any token for any other token on any supported network! Buy some AAVE on Ethereum using CAKE on the BSC network, swap USDT on Avalanche to USDC on Polygon, or any other case!

All swaps will be performed at the best rate and executed within one single transaction! Our contracts send cross-chain messages and communicate with each other to find the best rate and deliver assets to users on the desired chain! You no longer have to search liquidity pairs, browse dexes, or use bridges to transfer funds to another network. We do everything for you while keeping it super simple and easy to use.

Quick and simple Interchain swaps create tons of new opportunities in the liquidity markets and we are proud to be one of the very first protocols to introduce the Interchain approach!

Arbitrage made easy

Interport brings to the DeFi environment various solutions and advantages! One of the core ones is a simple and quick arbitrage opportunity!

How it regularly works:
you would buy assets for a lower price at one chain, bridge them to another chain where the price is higher and sell there.

What Interport allows to do is:
simply swap assets from the chain with a higher price to more of such assets on the chain with a lower price. As an example, you arbitrage AAVE between Ethereum and Polygon. ETH price spike resulted in 10 AAVE tokens = 1000 USDT. On Polygon, 10 AAVE tokens = 920 USDT Just swapping 10 AAVE tokens from Ethereum to AAVE tokens on Polygon would result in you having 10.8 AAVE tokens on Polygon. Easy as that, with one simple transaction with Interport.

Interchain Optimal Swaps

As one of the game-changing tools for DeFi. Interport will provide an opportunity to perform aggregated interchain swaps to achieve the best rate possible out of all available liquidity, in other words, Optimal Interchain swaps are like cross-chain aggregators.

The user will be able to buy or sell tokens on the preferred chain, while we analyze all the rates at all chains, perform swaps to the desired token, and send the amount back to the user at the desired chain.

Let’s say you would like to buy or sell a 1 million dollar worth of AAVE tokens. The price impact at one chain is most likely to result in 3–4%, however spreading the same transaction within 4 networks and a couple of liquidity pools would result in a way smaller price impact while limiting arbitrage opportunity for the markets.
