Keygen

Please refer to the Session creation section to learn how to create a new session.

Full example

ECDSA

main.dart

import 'package:silent_shard_sdk/silent_shard_sdk.dart' as sdk;

Future<sdk.DklsKeyshare> keygen(sdk.EcdsaSession session) async {
  final sdk.DklsKeyshare keyshare = await session.keygen();
  print('Keyshare created, public key: ${keyshare.publicKeyHex}');
  return keyshare;
}

EdDSA

main.dart

import 'package:silent_shard_sdk/silent_shard_sdk.dart' as sdk;

Future<void> keygen(sdk.EddsaSession session) async {
  final sdk.SchnorrKeyshare keyshare = await session.keygen();
  print('Keyshare created, public key: ${keyshare.publicKeyHex}');
}

• When session.keygen() is called, the app and the server exchange messages to generate a new MPC wallet.
• Two new DklsKeyshare are generated: one for the client and one for the server. Both shares together form the MPC wallet.
• The keyshare.publicKeyHex property is the public key of the MPC wallet in hex format.
