Navigate to the MetaMask Snaps Directory for a comprehensive catalog of currently accessible Snaps. Select one that seems interesting to you, and click ‘Install Snap’ to get started!

Dapps can also directly prompt you to install their accompanying Snap. For instance, a decentralized exchange (DEX) could prompt you to install their Snap, allowing them to automatically notify you right within MetaMask once your order has been fulfilled.

Snaps created by third-party developers are a Third Party Service as defined in the Consensys Terms of Use. You access, rely upon or use the Third Party Service at your own risk. Consensys disclaims all responsibility and liability for any losses on account of your use of Third Party Services. Consensys is not endorsing, recommending, or guaranteeing the safety of Snaps listed on the directory for your use or use for any reason. Always do your own research before installing any Snap, and carefully review the permissions requested.
