Universal Gas
UniversalX uses Universal Accounts' Universal Gas functionality, otherwise known as gas abstraction.
Thanks to Universal Gas, UniversalX users can pay the fees on a transaction using any Primary Token. Traditionally, transactions require fees to be paid in the native token of the network(s) you’re interacting with; however, in UniversalX, you can enjoy full gas flexibility.

How does this work?
Below is a quick overview of how the Particle Network Paymaster enables Universal Gas by paying native gas on behalf of users, and then pays itself back from the users' balance across different chains.
