✨ETH Denver 2023 Snaps Developer Guide✨

As you work on our bounties, we have prepared the following resources; you can also contact our Snaps team with the links below. 😁

*As well you can join our MetaMask Snaps Developer Discord


Before You Start ⚠️

Before you can build and test a Snap, you should have our experimental version of MetaMask installed. You will want to create a new browser profile or use a different browser than their regular MetaMask. Or disable "MetaMask proper" while MetaMask Flask is running.

This fork of MetaMask for developers (Flask) does everything a proper MetaMask wallet can do, with the addition of running Snaps.

From our webpage, you can link to the chrome extension for Flask.
*Flask only exists as a Chrome & Firefox extension. There is no fork or experimental version of MetaMask Mobile.

Start Here 🎯

To start building a Snap, follow this 5-minute tutorial teaching the basics tools, working with permissions, and adding an external API: Gas Fee Snap.

Bounties 🪙

You can watch the Bounties Video from the official ETH Denver 2023 Bounties Presentation.

Francesco Andreoli also presented on all ConsenSys Bounties on the first day of BUIDL week at ETH Denver.

Hackathon Tips 🪄

We seek new and exciting use cases made possible only via the Snaps platform.

Beyond innovation, practicality, functionality, and proper usage of MetaMask Snaps, which are all very important, communication of your idea and its features and explaining what your project does that you can't do without MetaMask Snaps is just as important.

Check out Ultimate Hackathon Survival Guide that you should check out!

But pretty simple, build a Snap, make it dope, submit it.
