MetaMask Snaps

MetaMask Snaps enables trustlessly extending the functionality of MetaMask at runtime. A Snap consist of two things: a JSON manifest and a JavaScript bundle. At present, Snaps can be published as npm packages on the public npm registry, or hosted locally during development. In the future, it will be possible to publish snaps on many different platforms, including arbitrary npm registries and IPFS.

We recommend creating your snap using this tool.
