What is XY Finance?

XY Finance is a cross-chain interoperability protocol aggregating DEXs and bridges. With the ultimate routing across multi-chains, borderless and seamless swapping is just one click away. For users, XY Finance provides cross-chain solutions with the most optimal routes, covering various tokens and creating ultra-fast transfers. For developers, XY Finance offers cutting-edge cross-chain API & widget to help broaden the project’s connection to all our 16+ supported chains!

xAsset Bridge
Upgrade you token into multi-chain world

xAsset Bridge helps projects Bridge Your Token to Different Chains, holders of the token could quickly and safely wrap their tokens to different chains. We supports two fungible token bridging methods

xAsset Bridge Example (DBF Bridge)
Bridging Method
Mint&Burn Method: The token will interact with xAsset Bridge by mint&burn manner on the chain. If the mint&burn method is adopted on the chain, while users bridge the token to other chains, the token will be transferred to the xAsset Bridge contract deployed on the chain and burned. While users bridge the token back from other chains, the token will be minted from the xAsset Bridge contract and sent to the user.

Pool-based Method: The token will interact with the xAsset Bridge by lock / unlock manner on the chain. If the Pool-based method is adopted on the chain, while users bridge the token to other chains, the token will be locked to the xAsset Bridge contract deployed on the chain. While users bridge the token back from other chains, the token will be unlocked from the xAsset Bridge contract and sent to the user.

To determine the appropriate scenario and method for your project, please evaluate the following information to choose the scenario and method that best suits your needs:

If your token is deployed only on 1 chain:

And if you want to deploy token(s) to a new chain -> Scenario1 : Mint&Burn Method

If your tokens are already deployed on N chains:

And if you want to enable token cross-chain functionality on these N chains -> Scenario2 : Pool-based

And if you want to deploy tokens to a new chain and enable token cross-chain functionality on n+1 chains -> Scenario 3: Combination of both methods.

Integration Flow
Step 1: Determine Your Bridging Method
Choose the scenario that best suits your project based on the Bridging Method and contact us through this form

Step 2: Implementation Phase
Once you have determined your bridging method, you can proceed with the implementation phase.

Scenario 1 : Mint&Burn Method
Here’s what you need to do:

Follow How to Develop Under XY Standards to deploy the token contract on the desired chain(s) and send your token address to the XY team.

XY team will provide you relay contract address , which you will need to set as the minter.

XY team will implement the cross-chain bridging mechanism (usually takes 2 weeks to complete)

You will receive a front-end bridge that allows users to bridge your token through XY Finance.

Scenario 2 : Pool-based
Here’s what you will proceed

Send your current token address to the XY team.

XY team will implement cross-chain bridging mechanism (Usually takes 2 weeks to complete)

Follow How to Deposit / Withdraw Liquidity to provide initial liquidity on the chain where you have deployed your token.

You will receive a front-end bridge that allows users to bridge your token through XY Finance.

(Optional) Establish your own liquidity notification using our API. You can find the details at Set up Notification of Liquidity Shortage

Scenario 3 (Combination of both methods) and Other Cases

Commonly asked questions:
1. How does xAsset Bridge charge fees?
The integration of xAsset Bridge does not charge any fees. However, when users utilize XY Finance in the future to bridge your project’s tokens, we will charge a certain fee from it.

2. What security measures does xAsset Bridge have?
Validators: The consensus mechanism of xAsset Bridge incorporates multiple validators, which support and consistently validate data requests from executors as needed.

Contract Independence: The Token Contact will be deployed by the project itself, while the Relay Contract will be deployed by XY, but it will be independent and non-upgradable, ensuring the security of the entire process.

3. If the token has taxes, can I integrate xAsset Bridge?
In the regular integration process, once you provide your token address to the XY team, we will deploy the relay contract for the xAsset Bridge service. If your token involves transfer taxes, you need to whitelist the relay contract address as both the ‘sender’ and ‘receiver’ in order to exempt these taxes during the bridge process.
