This build of MetaMask is a special developer release that contains early support for Filecoin, based on the upcoming MetaMask Snaps extensibility system. We are making this special developer build available so that Filecoin developers can start building Web3 sites based on Filecoin.
A few things to note: Although the Filecoin Snap is pre-installed in this build, the final product will install the Snap through the connect flow when a consumer connects to the site that depends upon Filecoin. There may be breaking changes between now and the production release and we’ll do our best to communicate these regularly.
To get started, simply visit our landing page, follow the instructions, and start building! 🎉
