XY Finance Infrastructure

To achieve the most convenient and fastest cross-chain swap process, XY Finance developed X Swap and Y Pool. While X Swap, as a decentralized non-custodial interoperability solution, communicates with and connects different chains, providing a convenient interface for users to transfer a wide range of tokens to different blockchains and L2 roll-ups, the Y Pool maintains an efficient cross-chain liquidity pool as a pillar of X Swap.

With these two prominent mechanisms as the infrastructure for their ecosystem, XY Finance is able to create an unbounded cross-chain environment for anyone who wants to transfer their assets to different chains and who wants to utilize their capital as liquidity for high-yield returns.

The ultimate goal of XY Finance is to provide the fastest & most reliable cross-chain solution for all Web3 natives. Rubic will facilitate this noble work! Enjoy the fastest, most secure cross-chain swaps at, and we’ll get back to you with more updates soon!

XY Finance: Security Measures

The XY Finance team has worked effortlessly to ensure the security of your funds. As you can see in the graph above, X Swap is mainly composed of two parts: Swapper and Consensus.

While Swapper handles the transfers for users of X Swap, Consensus comes in the role of the Validator. Security-wise, it is comprised of multiple nodes from different parties to guarantee the correctness of the cross-chain swap process and the validity of X Swap. Consensus detects the user’s request for cross-chain transfer and calls for Swapper to execute the swap transaction on the destination chain. Once the execution is completed, Consensus will validate the swap transaction and claim the credit by calling the Swapper on the source chain.

There are two roles involved in the XY Finance consensus mechanism:

1 — Executor: The one that executes the target chain transaction and claims the funds from the source chain.

2 — Validator: The one that validates the data of the executor’s target transaction and signs/approves the asset-claiming request from the executor.

To maximize security for their users, XY Finance completed the audit by BlockSec. Check out their audit report in the link below!
