Our goal was to create an email subscription pay master that covers gas fees for off-chain email correspondence. We modified the gated pay master and added server attributes to verify the email's validity. By querying the contract, we can determine if the email is true or false. This project aims to encourage email subscriptions without storing them on-chain and provide a gasless experience for users."}
