@astar-network/snap v0.7.9

Metamask Astar Snap

This project extends Metamask capabilities to include support for Astar & Shiden, and other Substrate- and FRAME-based blockchains in the Polkadot ecosystem.

What are Snaps?

Snaps is a system that allows anyone to safely extend the capabilities of MetaMask. A snap is a program that Metamask runs in an isolated environment that can customize the wallet experience.

For example, a snap can add new APIs to MetaMask, add support for different blockchain protocols, or modify existing functionality using internal APIs. Snaps is a new way to create web3 end user experiences, by modifying MetaMask in ways that were impossible before.

Learn more about snaps from the official Metamask documentation.

As of 2022-10-01, snaps are only supported in Metamask's developer build, Flask.
