Methods
import
▸ Future<Keyshare> import(privateKey, keyId, rootChainCode)
Import private key into MPC (client and server) keyshares

keyshare | Keyshare | The existing keyshare object to be refreshed. |
Returns
Future<Keyshare>
- Returns a future that resolves to a refreshed
Keyshareobject.
sign
▸ Future<string> sign(keyshare, messageHash, derivationPath)
Signs a message hash with the Ecdsa keyshare
Parameters
| Name | Type | Description |
