Frequently Asked Questions

Multisignature and Ledger Hardware Wallets

« Back to FAQ

This guide is meant for power users and those who want to store LBRY Credits on their Ledger Hardware devices before official support is added. If you are participating in the LBRY Swarm program, this solution will allow you to store LBC at a Multisignature address which typically requires more than 1 person to sign off on a transaction before it's sent to the network. It is important to test a single small transaction incoming and outgoing before using the wallet to store larger amounts. Also make sure a backup is taken (see instructions below).

Please note that the LBRY apps / SDK currently do not support outgoing transactions to multisignature wallets. Incoming transactions to the apps will work, but require a restart of the app afterward. Future support is planned for both.

Learn more about Multisignature wallets and how they work: Electrum Documentation , Creating a Multisignature Wallet. This documentation can also be referenced along with the steps below.


Installing and Running Electrum for LBRY

You can find the downloads and setup information for Electron LBRY on GitHub. Windows and Mac installers are provided, but Linux needs to be run from source as detailed on the install instructions. If you previously ran an old version and created wallets, they will need to be re-created in this new version. You can use the old version to send the funds to another wallet and then re-create a new one.

Setting up a Multisignature Wallet

You can also reference step by step instructions with images here or follow along below.

On the initial screen, you'll be asked to select a wallet file or create a new one. If this is the first time running it, proceed with a new file. If you have a wallet file already and want to create another, change the name of the file. Each user in the multisignature scheme will need to do this locally to create the same wallet (they all require to have started this process or have a key from the LBRY app wallet).

At the next prompt, you'll be asked for the wallet type - choose Multi-signature. Next, choose how many people (including the current person/wallet) will be sharing this wallet (from X cosigners) and how many are required to approve the transaction (require X cosigners). For example, if you choose 2 of 3, any 2 people will need to sign off to send the transaction.

Next, you'll be asked to provide a key for each wallet, including the current one, which is first. If you want to use your LBRY app's key / seed, proceed with "I already have a seed". You can find this seed inside your default_wallet file that's created as part of your app installation. Open the default_wallet and you'll see a seed there. The wallet must not be encrypted to view it (you can decrypt temporarily via Desktop App > Settings). Otherwise, you can proceed with a new seed or Hardware device (requires Ledger device, see below. Make sure to back up the seed if creating a new one - this can be done by copying the seed phrase or backing up the wallet file that's created.

You will be given a Master Public Key that will be shared with the other co-signers when they create the same wallet locally. Next, you will be prompted for the next cosigners key. This would come from their PC while setting up the same wallet, or from their default_wallet file by opening it and using the "public_key": portion (this assumes they will create their Electrum wallet from this LBRY app seed). Proceed with all cosigners until they are all filled out. Lastly, enter a password to encrypt the multisignature wallet.

Receiving LBC in the Wallet

To receive LBC in the Electrum wallet, go to the Receive tab to view an address or enable the addresses view by going to View > Show Addresses from the top menu bar. Here you will see all available addresses on the wallet. Multisignature addresses with start with an r, regular wallets, including hardware ones, will start with a b.

Sending Multisignature Transactions

Once all parties have their multisignature wallets configured and LBC has been received, you can now send LBC to other addresses. Anyone in the party can start by creating a transaction. Once the transaction is created, you'll see an option to Copy or Export it. It must be shared via one of those two methods with however many cosigners are needed (i.e. for 2 of 3, 1 other cosigner must sign it). Send the other cosigner the copied message or exported file. You may also be able to share the Transaction Id and import it that way, but the copy/file method will always work.

The cosigner has to open the wallet on their PC and go to Tools > Load Transaction and then choose from text (if copied) or from file (if export was used). They can then sign the transaction. Each cosigner will need to do the same to send the transaction on the network.

Ledger Hardware Wallet with Electrum

You can use your Ledger device with LBRY Electrum to store LBC. Please follow these directions on how to install it on your device and then use the above directions to setup a new wallet. For a normal account (non-multisignature), you will choose Standard wallet when setting up the device, and then Use a hardware device, and then follow the prompts.

Official support with Ledger will be coming at a later date.

Electrum Wallet File Location

Electrum wallet files and blockchain data can be found in the App Data Roaming directory under Electrum-lbry. The wallet is located in %appdata%\Electrum-lbry\wallets and the data in %appdata%\Electrum-lbry on Windows. On Mac/Ubuntu, search your system for the Electrum-lbry folder or the name of the wallet file. The wallet should be backed up if you do not have your phrase or are not using the LBRY Desktop wallet.


If the balance is not updating properly or transaction not showing confirmed, try restarting the application. To resync the wallet data, delete the blockchain_headers file in %appdata%\Electrum-lbry and restart the application.

If you are having trouble sending due to fees, make sure that fee estimation is set to static, and edit fees manually is checked under Tools > Preferences.
