Set up Relayer instances

Go to https://defender.openzeppelin.com/#/relay and sign up
Hit the Create Relayer button to create new Relayer instnace
Input instance name, choose network and hit Create
It will generate an EOA and show you it's address, API Key and API's Secret Key
- You need to write down API's Secret Key if you want to send request to your relayer outside of Defender services
- But you don't have to if you are using it from within, e.g., from an Autotask instance, it will automatically handle the authentications for you
- And it is easy to create a new API key so don't worry too much if you forgot the secret key
Finally you need to fund this relayer by sending ETH to it
- For relayers in Goerli and Rinkeby networks, you don't have to fund them yourself, Defender will top up the balance for you
- Defender will send you email notification once the relayer is running low on funds (below 0.1 ETH)
Now you can use the relayer from other services like Autotask

You can create new API keys or sending arbitrary transactions like sending ETH/tokens from your relayer
