    Tron HD wallet to generate offline private keys, mnemonic seeds and addresses.


    npm install tron-wallet-hd

    Sample recommended usage:

    // the seed is stored encrypted by a user-defined password
    var password = prompt('Enter password for encryption', 'password');
      password: password,
      // seedPhrase: seedPhrase, // Optionally provide a 12-word seed phrase
      // salt: fixture.salt,     // Optionally provide a salt.
                                 // A unique salt will be generated otherwise.
    }, function (err, ks) {
      // Some methods will require providing the `pwDerivedKey`,
      // Allowing you to only decrypt private keys on an as-needed basis.
      // You can generate that value with this convenient method:
      ks.keyFromPassword(password, function (err, pwDerivedKey) {
        if (err) throw err;
        // generate five new address/private key pairs
        // the corresponding private keys are also encrypted
        ks.generateNewAddress(pwDerivedKey, 5);
        var addr = ks.getAddresses();
        ks.passwordProvider = function (callback) {
          var pw = prompt("Please enter password", "Password");
          callback(null, pw);

    keystore Function definitions

    These are the interface functions for the keystore object. The keystore object holds a 12-word seed according to [BIP39][] spec. From this seed you can generate addresses and private keys, and use the private keys to sign transactions.


    const hdWallet = require('tron-wallet-hd');
    const keyStore=hdWallet.keyStore;


    keystore.createVault(options, callback)

    This is the interface to create a new lightwallet keystore.


    • password: (mandatory) A string used to encrypt the vault when serialized.
    • seedPhrase: (mandatory) A twelve-word mnemonic used to generate all accounts.
    • salt: (optional) The user may supply the salt used to encrypt & decrypt the vault, otherwise a random salt will be generated.

    keystore.keyFromPassword(password, callback)

    This instance method uses any internally-configured salt to return the appropriate pwDerivedKey.

    Takes the user's password as input and generates a symmetric key of type Uint8Array that is used to encrypt/decrypt the keystore.


    Returns true if the derived key can decrypt the seed, and returns false otherwise.


    Generates a string consisting of a random 12-word seed and returns it. If the optional argument string extraEntropy is present the random data from the Javascript RNG will be concatenated with extraEntropy and then hashed to produce the final seed. The string extraEntropy can be something like entropy from mouse movements or keyboard presses, or a string representing dice throws.


    Checks if seed is a valid 12-word seed according to the [BIP39][] specification.

    keystore.generateNewAddress(pwDerivedKey, [num])

    Allows the vault to generate additional internal address/private key pairs.

    The simplest usage is ks.generateNewAddress(pwDerivedKey).

    Generates num new address/private key pairs (defaults to 1) in the keystore from the seed phrase, which will be returned with calls to ks.getAddresses().


    Takes a serialized keystore string serialized_keystore and returns a new keystore object.


    Serializes the current keystore object into a JSON-encoded string and returns that string.


    Returns a list of hex-string addresses currently stored in the keystore.


    Given the pwDerivedKey, decrypts and returns the users 12-word seed.

    keystore.exportPrivateKey(address, pwDerivedKey)

    Given the derived key, decrypts and returns the private key corresponding to address.

    utils Function definitions


    const hdWallet = require('tron-wallet-hd');
    const utils=hdWallet.utils;

    generateMnemonic() : Generates a string consisting of a random 12-word seed and returns it.

    const seed = utils.generateMnemonic();

    validateMnemonic(mnemonic) : Checks if seed is a valid 12-word seed according to the BIP39 specification and returns a boolean value.

    const seed = "hello"
    const isValidSeed = utils.validateMnemonic(seed);
    console.log(isValidSeed) //false

    generateAccountsWithMnemonic(mnemonic, index) : Generates public and private key-value pair using the given mnemonic seed and index. it's an asynchronous method.

    • mnemonic: mnemonic seed to generate addresses.
    • index (optional):Number of accounts to generate, Default value is 5.
    const seed = utils.generateMnemonic();
    const accounts = await utils.generateAccountsWithMnemonic(seed,2);

    getAccountAtIndex(mnemonic,index) : Returns public and private key-value pair stored at the specified index using the given mnemonic seed, it's an asynchronous method.

    • mnemonic: mnemonic seed to get the key-value pair.
    • index: index value at which key-value pair is stored. Default value is 0.
    const seed = "your mnemonic seed";
    const account = await utils.getAccountAtIndex(seed,1);

    validatePrivateKey(privateKey) : Validates the given private key and returns a boolean value.

    const pk= "your private key";
    const isValidPK = utils.validatePrivateKey(pk);

    getAccountFromPrivateKey(privateKey) : Validates the given private key and returns tron address associated with the given private key. it's an asynchronous method.

    const pk= "your private key";
    const address = await utils.getAccountFromPrivateKey(pk);

    validateAddress(address) : Validates the given tron address and returns a boolean value. Supports both base58 and hex format.

    const isValidAddress1 = utils.validateAddress("41c7cfb121ffac3fbf8c4dd48e17b055cae2ed1314");
    console.log(isValidAddress1) //true
    const isValidAddress2 = utils.validateAddress("TRquwhRa9Eiva1ri1D6CmtxuNv9R6PPXGD");
    console.log(isValidAddress2) //true
    const isValidAddress3 = utils.validateAddress("TRquwhRa9Eioabbabbbbqqwwwznaqwrtzxzbzbbz");
    console.log(isValidAddress3) //false
