Silent Shard Snap

The Silent Shard Snap aims to remove single points of failure pertaining to handling of private keys and seed phrases i.e., in current designs of wallets the private keys are stored at a single location- the local storage of the browsers.

Users have been losing access to wallets’ accounts and associated services due to phishing scams and private key theft through associated attack vector for years. This has resulted in loss of approximately USD $14 billion in 2021 alone, a blot in the face of self-sovereign non-custodial wallets which is one of the core tenets of crypto. The Silent Snap Shard aims to remove this entirely with our MPC SDK for {2,2} TSS.

Using Snap, allows us to prove how Multi-Party Computation-based signature schemes can be built at the core of wallets like MetaMask. Users will be able to get access to any WebApps using MetaMask as one shard node wherein Snap provides a way to extend MetaMask’s functionality- provide DAapps with JSON-RPC API methods for MPC supported signatures. Essentially, the snap comprises of the core threshold signature functions and WebApps would be provided with functionality to make necessary calls and handling UI elements.

How to run

  • Use node version 18 or greater.
  • Use yarn version 3.2.1
  • Now run, yarn install, to install the libraries
