Keygen

This distributed key generation forms the basis for all subsequent MPC operations, providing a secure foundation for the wallet with enhanced privacy and security guarantees.

Step 1 : Create Session​

Step 2 : Perform Keygen​

  • Call duoSession.keygen() which returns Result of Success with Keyshare bytes as Data object or Failure with an error.

Example​

Example.swift
    func performKeygen(duoSession: DuoSession) async -> Data? {
        let result: Result<Data, any Error> = await duoSession.keygen()
        // returns nil if operation fails or other flow you might have
        switch result {
        case .success(let dataBytes):
            do {
                // do something with bytes
                Swift.print(dataBytes)
                return dataBytes
            }
        case .failure(let error):
            do {
                // show error to user or abort process
                Swift.print(error)
                return nil
            }
        }
    }
  • duoSession.keygen() performs message exchange between mobile and server to generate a new MPC wallet.
  • Two new "shares" are generated: one for the client(on mobile) and one for the server(on server). Both shares together form the MPC wallet.
  • Result of duoSession.keygen() could be a Success with Data (client's keyshare) or Failure with error
  • SilentShardDuo.ECDSA.getKeysharePublicKeyAsHex or SilentShardDuo.EdDSA.getKeysharePublicKeyAsHex could be used to get the compressed public key of the MPC wallet. Refer to SDK-Reference for additional Info and Utils.
