Migration to smart contract v2

Upgrading your current Unizen API implementation to Version 2 is a simple process. Follow these steps to seamlessly transition to the new version and take advantage of its improved features.

Migration Steps

1. Enable Version 2 in Quote Requests

   • In your quote endpoint, include the parameter version=v2.

   • This ensures that our system utilizes the latest version of the smart contracts.

2. Update the Unizen Contract Addresses Package

   • Upgrade to the latest Unizen contract addresses package to retrieve the new unizenRouter address.

   • This is the only address needed for approvals—no more version-specific handling.

3. Use the Unizen Router for Transaction Execution

   • When executing a transaction from the user's wallet (for non-gasless trades), use the Unizen Router address.

   • The swap endpoint will continue to return the correct contract details, including the necessary approval information (if applicable, unless it’s a Permit2 trade).

That's It!

With just these simple steps, your integration will be fully compatible with Version 2 of Unizen’s API. By upgrading, you ensure improved efficiency, reduced costs, and enhanced functionality.
