Creating a Serverless EVM Explorer for ETH and Base

Just wanted to share a quick guide on how to set up your own serverless on-chain monitoring tool using Cloudflare Workers. 1. Setting Things Up First, go to Cloudflare and create a new Worker. You’ve got two ways to deploy it: - Use Wrangler (CLI) if you’re experienced. - Or just copy and paste the script directly into Cloudflare’s web editor, way easier for most. 2. Connecting to the Chain (RPC) You’ll need to connect to the blockchain. - Look for an RPC provider (you can grab a free one, but having a paid option as a backup is a smart move). - In your Cloudflare settings, set up Secret Variables: MY_RPC_URL (for main) and MY_RPC_URL2 (for backup). 3. Data Collection To gather and parse extra data, we can use Blockscout’s free tier or etherscan. - Sign up for Blockscout or etherscan. - Generate an API Key. - Add it to your Cloudflare Secret Variables as: BLOCKSCOUT_API_KEY. 4. The Script I’ve made the worker script open-source. It takes care of request routing and API calls on its own.
