const hive = new Hive(transport);

const version = await hive.getAppVersion();
console.log("Current version:", version);

const name = await hive.getAppName();
console.log("App name:", name);

const publicKey = await hive.getPublicKey(`48'/13'/0'/0'/0'`);
console.log("Public key:", publicKey);

const signature = await hive.signMessage('This is a message to sign', `48'/13'/0'/0'/0'`);

API

getAppVersion

Get current version for HIVE App installed on a Ledger.

async getAppVersion(): Promise<string>

getAppName

Get name for HIVE App installed on a Ledger.

async getAppName(): Promise<string>

getPublicKey

Retrieve public key from specified BIP32 path. You can set additional parameter confirm: boolean which will ask the user to confirm the Public Key on his Ledger before returning it.

async getPublicKey(path: string, confirm?: boolean): Promise<string>

getSettings

Read settings from Ledger. This can be used to determine if the user has enabled the "blind signing" option in the HIVE App.

async getSettings(): Promise<Settings>

signTransaction

Sign basic transaction with specified key path. This method will return signed transaction (transaction with additional signatures property). Please note that extensions are not yet supported for most transactions and operations (except beneficiaries for comment_options and end_date for update_proposal). Transaction cannot contain more than one operation, otherwise ledger will refuse the transaction.

async signTransaction(tx: Transaction, path: string, chainId?: string): Promise<SignedTransaction>

You can also provide optional chainId which may be useful for tests on Hive testnet. If not provided, Ledger will use production chainId.

signHash

Sign transaction digest with specified key path. This method will return a single signature. Please note that this method requires blind signing mode enabled in settings, otherwise ledger will refuse it.

async signHash(digest: string, path: string): Promise<string>

Transaction need to he serialized with proper chainId up front. This can be done with static method called getTransactionDigest

signMessage

Sign message with specified key path. This method will return a single signature. May be used to prove ownership of a private key.

async signMessage(message: string, path: string): Promise<string>
