# How to use it

## Verified SDK

The best way to interact with our API is to use the Verified SDK that enables third party applications to use both gas less and regular transactions that use gas to execute transactions on the ethereum protocol supported chains such as the Ethereum mainnet and L2 networks such as Polygon, Gnosis, Binance chain and Avalanche.

## Verified REST API

You can generate an API key by requesting Verified Network admin here.
