Just published the ERC-4337 part of my Gasless Onboarding tutorial.

It’s a hands-on guide to sponsoring gas so your users don’t need ETH to get started. Covers UserOps, bundlers, paymasters, and how to wire it all together in a real dapp.

What you’ll learn:

1. What actually happens in a UserOperation
2. How to sponsor gas with your own paymaster
3. Why ERC-4337 doesn’t need protocol changes
4. How to make onboarding feel like Web2

You’ll build a flow where new users can mint NFTs without ever touching ETH.

Let me know what you build with it.
