What is Kinetex?

Kinetex is a decentralized application (dApp) designed to provide users with a secure, efficient, and seamless method of swapping digital assets across different blockchains. Leveraging cutting-edge technology and advanced cryptographic techniques, Kinetex ensures that users can quickly and safely transfer their tokens from one chain to another.

Key Features

Kinetex stands out from the crowd, offering several unique features:

Instant Transfers

One of the significant advantages of Kinetex is the ability to provide instant transfers. Traditional cross-chain swaps can be time-consuming, especially when bridges are involved. Kinetex, on the other hand, expedites this process. It enables users to send their tokens instantly to the recipient blockchain, ensuring a smooth and rapid swapping experience.

Collateral-Backed Security

Safety is at the forefront of Kinetex. To ensure the security of each swap, market makers must hold collateral for each order they execute. This collateral acts as a guarantee for the user, guaranteeing the safety of their assets even if the market maker does not send the exchanged tokens. In the event of a delay or failure by the market maker to execute an order on time, the order is automatically canceled and the collateral liquidated, ensuring that its user assets are not lost.

Zero-Knowledge Proofs

Kinetex incorporates Zero-Knowledge proofs (ZK proofs), a groundbreaking cryptographic technique. These proofs allow one party to prove to another that a statement is true, without conveying any additional information apart from the fact that the statement is indeed true.

In Kinetex, ZK proofs are used to verify token transfers between different chains. If a market maker fails to send tokens to a user, a Prover (a role in our system) constructs a ZK proof of the failed trade. This proof can be used to initiate a refund from the locked collateral, ensuring the security and integrity of every transaction.

In conclusion, Kinetex offers an innovative, secure, and efficient solution for swapping tokens across different blockchains. By combining instant transfers, collateral-backed security, and ZK proofs, Kinetex provides users with a robust platform that takes cross-chain swaps to the next level.

To validate transactions and ensure the security of transfers, we implemented the solution based on zero-knowledge technology. We forked LightClient implementation from SuccinctLabs, in which we made changes and optimizations for use in cross-chain trading. Our main difference is instant cross-chain transfers and strong gas optimization. We managed to reduce gas costs to 60-90k gas units on all supported networks.

We also applied several technologies from the sponsors and added to the overall architecture of the project, such as:

Our simplified resolver example uses 1inch Fusion technology to settle orders on-chain, allowing to make most profitable deals.

In the example, the liquidator uses AAVE's Flashloans to close the market maker's debts and release the asset to the user while retaining the liquidation profit.

Uniswap protocol is used for on-chain asset exchange at the time of order liquidation.

Gnosis chain has been added as a network through which we can provide Zk-proof.
