About MetaMask Snaps

MetaMask Snaps is the next phase in MetaMask's evolution. Currently available via MetaMask Flask, our developer preview build, it allows MetaMask, our partners, and the entire web3 community to add radical new functionality to MetaMask.

Install MetaMask Flask and check out live examples like Bitcoin, Filecoin, and a password manager. We aim to make adding entirely new networks and use cases as easy as it is to write a Dapp today.
