Gas Sponsorship API Endpoints

The Gas Coverage API Endpoints allows you to sponsor gas fees for your users, removing the biggest barrier to entry.

What are Gas Coverage API Endpoints?

The Gas Coverage API is a set of methods that allow you to sponsor gas for your users’ transactions, abstracting away the concept of “gas” from them. Below are the Gas Manager Admin API endpoints available and the corresponding docs for each of them.
