0/ @MetaMask snaps are a game-changer for the biggest Ethereum wallets UI/UX & expands it beyond the Ethereum / EVM world. 🦊
Snaps make MetaMask a true multichain wallet & enable open & permissionless innovation around wallet features! 🚀
A 🧵 on what you can do with snaps 👇
1/ The @MetaMask Snaps Open Beta offers a first look at what's possible when extending the capabilities of your wallet.
It's an opportunity for those familiar with beta testing to explore features crafted by talented community devs.
2/ @MetaMask Snaps represents an open-source framework, designed to safely enhance the MetaMask functionality, paving the way for new web3 user interfaces.
3/ Defined as JavaScript programs, Snaps operate in a confined environment, tailoring the wallet's user experience to user needs.
The scope of a Snap's operation is based on the permissions granted by users upon its installation.
4/ By allowing feature installations for wallet customization, Snaps are a promising step towards scaling the wallet functionality in the future. For now, snaps primarily evolve around three main categories:
🔹 Interoperability
🔹 Transaction Insights
🔹 Notifications
5/ A snap can add new API methods to @MetaMask, add support for different blockchain protocols, or modify existing functionalities using the Snaps JSON-RPC API.
6/ Features include:
🌟 Dialogs
Display custom alert, confirmation, or prompt screens in MetaMask.
🌟 Notifications
Notify users directly in MetaMask, or in their OS.
🌟 Encrypted storage
Securely store and manage data on the user's device.
7/
🌟 Non-EVM chain support
Control non-EVM accounts and assets in MetaMask.
🌟 Transaction insights
Provide transaction insights in MetaMask's pre-transaction window.
🌟 Cron jobs
Schedule periodic actions for your users.
8/
🌟 Custom UI
Display custom UI in MetaMask using a set of pre-defined components, including inline Markdown.
🌟 Network access
Make API calls using `fetch()`.
9/ To ensure security, snaps run in a sandboxed environment and use a permissions model to protect your data and respect your consent.
Snaps don’t have access to your @MetaMask account data. When installing a Snap, you can always verify the permissions you are granting.
10/ Snaps currently featured in the @MetaMask Snaps Directory have been audited by the MetaMask team and third parties.
Over time, MetaMask aims to open up the auditing process to create a fully permissionless platform though.
