| `account`      | `Account` | Signer account to request signatures and send transaction through                                                                                                                                                                              |
| `usesECDSADN?` | `boolean` | Optional flag indicating whether the signer supports signing using ECDSA-DN (deterministic nonce) algorithm, this allows the wallet to produce reproducible entropy. Only pass `true` here if you are 100% sure that the signer supports this! |
