Enhance the security of your MetaMask wallet with Silent Shard! Designed exclusively for existing MetaMask users, Silent Shard provides an additional layer of protection for your funds.
Silent Shard empowers you to create an additional distributed wallet account with an advanced level of fund protection through Multi-Party Computation (MPC). Your private key is distributed between the MetaMask browser extension with Silent Shard Snap and the Silent Shard mobile application (Android or iOS). Initiate your transactions from the MetaMask extension in your desktop browser and confirm them with your phone.
This solution eliminates the single point of failure for the private key, as it is no longer stored or processed in one place.
