Overview

This template deploys an app that checks Ethereum gas price every hour using the Etherscan API, and sends email via Resend if the price crosses your pre-defined threshold. Configure the following environment variables while deploying the service:

• ETHERSCAN_API_KEY: Etherscan API key to check Ethereum gas price; get it here.
• RESEND_API_KEY: Resend API key to send email notifications; get it here.
• EMAIL_FROM: Email address to send alert from, as configured in Resend.
• EMAIL_TO: Email address to send alert to, as configured in Resend.
• PRICE_THRESHOLD: Send email if Ethereum gas price drops below this threshold (gwei).

Note: The template does not allow cron schedule to be defined, so set up the hourly run (0 * * * *) in the service settings once it's deployed.
