Choose your hardware wallet


Ledger Nano S

Blockstream Green multisig wallets can be used with hardware wallets. This gives you the best of both worlds by combining Blockstream Green’s multisig security with the private key cold storage provided by a hardware wallet.

A Blockstream Green wallet associated with a hardware wallet creates a 2-of-2 multisig wallet where one key is held on your hardware wallet, and the second key is held by the Blockstream Green service. The second key serves to authorize transactions through Two-Factor Authentication.

Attention

When you create a new Bitcoin wallet with your hardware wallet on Blockstream Green, it will be different from:

  • Any wallet previously created on the hardware wallet

  • Any wallet previously created in Blockstream Green


On what network do you want to use your wallet?

___

Bitcoin Multisig Wallet

Create New Wallet

Prerequisites

  1. Check the columns of this table to verify that your device supports using Green with a Ledger Nano S, if it does, install Green on your device

  2. Make sure you have initialized your Ledger Nano S

  3. Make sure you safely stored the recovery phrase and PIN you created when you initialized your Ledger Nano S. You will need the PIN to log into your Green multisig wallet, and the recovery phrase is needed to recover your funds in case you lose or break your Ledger Nano S

Connect Ledger Nano S to Green

  1. Plug the hardware wallet into your Android device where Green is installed

  2. Green will open automatically, or select Green from the pop-up menu that appears if you have multiple companion apps compatible with Ledger Nano S

  1. Authenticate with PIN on your hardware wallet

  2. From your hardware wallet dashboard open the Bitcoin app

Congratulations, you are now logged into your new 2-of-2 Blockstream Green wallet.

Note

If you didn’t have an existing Blockstream Green wallet associated with this hardware wallet device, a new 2-of-2 wallet will be created. If you had already logged into a Blockstream Green wallet with your hardware wallet, you will be automatically logged back into it.

Login

Connect Ledger Nano S to Green

  1. Plug the hardware wallet into your Android device where Green is installed

  2. Green will open automatically, or select Green from the pop-up menu that appears if you have multiple companion apps compatible with Ledger Nano S

  1. Authenticate with PIN on your hardware wallet

  2. From your hardware wallet dashboard open the Bitcoin app

Receive

To receive Bitcoin, all you need to do is provide a receiving address to the sender.

More details about how Bitcoin receiving addresses work

What’s a receiving address?

A Bitcoin receiving address is a string of numbers and letters. You can create a receiving address by selecting “Receive” from the main screen. Your wallet will generate a new receiving address each time you prompt it for one. While it is possible to reuse old addresses, we strongly advise against this because it lessens your privacy.

How do I receive bitcoin on it?

Once you can see what your new address is, you’ll need to communicate it to the sender. If you need to send over a distance, a text message or email is an effective way to do it.

If you are physically beside the person who will be sending you Bitcoin, another option is to use the QR code, which the sender can scan to get the receiving address. This is really convenient if the sender is using a mobile wallet.

Avoid mistakes!

Copy and paste addresses rather than manually type them out, and also double or triple check every time, especially for larger amounts. If the address is wrong, any bitcoins sent can become lost forever, so be very careful!

Where will I see if I received my bitcoin?

Once someone has sent a transaction to your Blockstream Green wallet, it should appear in your transaction list page. At first, it will be labelled “unconfirmed”. At this point, you should not consider the coins to have been received, because the transaction may still get overwritten or canceled. The transaction will over time accumulate “confirmations” as new blocks are mined in the Bitcoin network. Once your transaction reaches 6 confirmations, your wallet will list it as “confirmed” and you can consider the coins received.


Send

To send a transaction, select “Send” from the main screen.

Input your recipient

You will need to get the receiving address from the recipient, and enter it (either by typing or pasting it in, or by scanning the receiver’s QR code).

../../_images/send-receipient2.png

Select the amount and the desired priority

Input the amount of Bitcoin that you want to send, and hit send.

../../_images/send-amount2.png

Your wallet will also automatically calculate a fee for your transaction, which is necessary to have the network accept it.


Review all the details and double check they are correct!

Double check with your recipient that the address, amount and fee are all correct. Bitcoin transactions cannot be reversed, once sent no one can help you if you made a mistake.

../../_images/send-review2.png

Don’t trust, verify the recipients and amounts on your hardware wallet

Sliding to send normally signs the transaction on your device. When your keys are stored on your hardware wallet, you will have to confirm signing the transaction from your hardware device. In order to do so, verify that the recipients and amounts displayed on your Green Companion app are the same displayed on your hardware wallet.

  • To is the actual recipient of the transaction

  • Change is your own address where you will receive back your change

Check the verification steps in this video for reference:


Authorize the transaction with your Two-Factor-Authentication

At the end of the process, Green will prompt you to authenticate with 2FA via Google Authenticator (T-OTP), email, SMS or call, depending on what you have activated.

Lost or Broken Device

In the event that a hardware wallet used to log into a Blockstream Green wallet is lost or broken, there are two options for restoring your Blockstream multisig Green wallet.

Option 1 - Buy new Ledger device

  1. Buy a new hardware wallet, possibly the same model you lost or broke, otherwise contact support to get advice on how to recover your funds

  2. Restore on your new hardware device the recovery phrase you originally created with your lost/borken Ledger device. Follow these instructions for Nano S and these for Nano X

  3. Finally connect your new hardware device to your Green companion app, like you’ve always done

Option 2 - Emergency restore via software signer

If you cannot buy a new Ledger device and yet you need to move funds locked on your Green multisig wallet, you can restore the recovery phrase originally created on your Ledger device onto your Green companion app.

Caution

This method ensures access to any funds, but decreases the security of the keys you once stored on your hardware wallet. If you need to use this method, we suggest you move your funds back to a new reasonably secure wallet setup as soon as you are out of your emergency situation.

  1. Get the recovery phrase you originally created with your lost/borken Ledger device

  2. Select the correct network, Bitcoin or Liquid

  3. Tap on Restore Green Wallet and use your Ledger recovery phrase to proceed. During this process Green will prompt you to create a PIN to quickly access your wallet, after that you will gain access to your funds

  4. You can now move these funds onto a new wallet, or access your wallet via the PIN set at step 3


Liquid Multisig Wallet

Create New Wallet

Prerequisites

  1. Check the columns of this table to verify that your device supports using Green with a Ledger Nano S, if it does, install Green on your device

  2. Make sure you have initialized your Ledger Nano S

  3. Make sure you safely stored the recovery phrase and PIN you created when you initialized your Ledger Nano S. You will need the PIN to log into your Green multisig wallet, and the recovery phrase is needed to recover your funds in case you lose or break your Ledger Nano S

  1. On your hardware wallet, install the Liquid app via Ledger Live Manager

Before connecting your hardware wallet, make sure Liquid is the pre-selected network on Green

Green wallets can be created, restored or accessed on Bitcoin by default, but you can use other networks as well, like Liquid or Testnet.

To create, restore or access a Liquid wallet, change network by tapping on the network name in the center of the landing page e.g. Bitcoin in the image below.

Note

If you have an existing wallet protected with PIN, tap on the back arrow on the top right to reach the landing page, or switch network from settings after login.

../../_images/landing2.png

Select Liquid among the available networks and then tap on the Save button.

Receive

Warning

Ledger currently supports a limited set of assets

  • Liquid Bitcoin, L-BTC

  • Tether USD, USDt

Receiving any other asset will make you unable to spend it, unless you perform an emergency restore

Attention

Verify the address displayed on your hardware wallet

Please verify that the address shown on your hardware wallet matches the one displayed on the Green companion app, and also confirm with the sender that they are using this same address.

To receive Liquid Bitcoin or any other Issued Asset, all you need to do is provide a receiving address to the sender.

../../_images/receive-liquid1.png

More details about how Liquid receiving addresses work

What’s a receiving address?

A Liquid receiving address is a string of numbers and letters. You can create a receiving address by selecting “Receive” from the main screen.

Your wallet will generate a new receiving address each time you prompt it for one. While it is possible to reuse old addresses, we strongly advise against this because it lessens your privacy.

Does it preserve my privacy?

All addresses in Liquid are, by default, blinded using Confidential Transactions. Blinding allows to cryptographically hide the amount and type of asset being transferred from everyone, except the sending and receiving parties.

What assets can I receive with these addresses?

You can receive any asset issued on Liquid, including, but not limiting to, these assets

How do I receive Liquid bitcoin and other assets on these addresses?

Once you can see what your new address is, you’ll need to communicate it to the sender. If you need to send over a distance, a text message or email is an effective way to do it.

If you are physically beside the person who will be sending you Bitcoin, another option is to use the QR code, which the sender can scan to get the receiving address. This is really convenient if the sender is using a mobile wallet.

Avoid mistakes!

Copy and paste addresses rather than manually type them out, and also double or triple check every time, especially for larger amounts. If the address is wrong, any asset sent can become lost forever, so be very careful!

Where will I see if I received my bitcoin?

Once someone has sent a transaction to your Blockstream Green wallet, it should appear in your transaction list page. At first, it will be labelled “unconfirmed”.

Transactions on Liquid are settled with finality after 2 blocks, therefore you can consider your funds to be finally received within 2 or 3 minutes, under normal network conditions.


Send

To send a transaction, select “Send” from the main screen.

Input your recipient

You will need to get the receiving address from the recipient, and enter it (either by typing or pasting it in, or by scanning the receiver’s QR code).

../../_images/send-recipient-liquid1.png

Select what asset you want to send, the amount and the desired priority

Select the asset you wish to send and input the amount that you want to send, and hit send.

../../_images/send-amount-liquid1.png

Your wallet will also automatically calculate a fee for your transaction, which is necessary to have the network accept it and to avoid Denial of Service.


Review all the details and double check they are correct!

Double check with your recipient that the address, asset, amount and fee are all correct. Liquid transactions, like Bitcoin transactions, cannot be reversed, once sent no one can help you if you made a mistake.

More details about how Bitcoin receiving addresses work

What’s a receiving address?

A Bitcoin receiving address is a string of numbers and letters. You can create a receiving address by selecting “Receive” from the main screen. Your wallet will generate a new receiving address each time you prompt it for one. While it is possible to reuse old addresses, we strongly advise against this because it lessens your privacy.

How do I receive bitcoin on it?

Once you can see what your new address is, you’ll need to communicate it to the sender. If you need to send over a distance, a text message or email is an effective way to do it.

If you are physically beside the person who will be sending you Bitcoin, another option is to use the QR code, which the sender can scan to get the receiving address. This is really convenient if the sender is using a mobile wallet.

Avoid mistakes!

Copy and paste addresses rather than manually type them out, and also double or triple check every time, especially for larger amounts. If the address is wrong, any bitcoins sent can become lost forever, so be very careful!

Where will I see if I received my bitcoin?

Once someone has sent a transaction to your Blockstream Green wallet, it should appear in your transaction list page. At first, it will be labelled “unconfirmed”. At this point, you should not consider the coins to have been received, because the transaction may still get overwritten or canceled. The transaction will over time accumulate “confirmations” as new blocks are mined in the Bitcoin network. Once your transaction reaches 6 confirmations, your wallet will list it as “confirmed” and you can consider the coins received.


Send

To send a transaction, select “Send” from the main screen.

Input your recipient

You will need to get the receiving address from the recipient, and enter it (either by typing or pasting it in, or by scanning the receiver’s QR code).

Select the amount and the desired priority

Input the amount of Bitcoin that you want to send, and hit send.

Your wallet will also automatically calculate a fee for your transaction, which is necessary to have the network accept it.


Review all the details and double check they are correct!

Double check with your recipient that the address, amount and fee are all correct. Bitcoin transactions cannot be reversed, once sent no one can help you if you made a mistake.

Don’t trust, verify the recipients and amounts on your hardware wallet

Sliding to send normally signs the transaction on your device. When your keys are stored on your hardware wallet, you will have to confirm signing the transaction from your hardware device. In order to do so, verify that the recipients and amounts displayed on your Green Companion app are the same displayed on your hardware wallet.

Check the verification steps in this video for reference:


Authorize the transaction with your Two-Factor-Authentication

At the end of the process, Green will prompt you to authenticate with 2FA via Google Authenticator (T-OTP), email, SMS or call, depending on what you have activated.

Lost or Broken Device

In the event that a hardware wallet used to log into a Blockstream Green wallet is lost or broken, there are two options for restoring your Blockstream multisig Green wallet.

Option 1 - Buy new Trezor device

  1. Buy a new hardware wallet, possibly the same model you lost or broke, otherwise contact support to get advice on how to recover your funds

  2. Restore on your new hardware device the recovery seed you originally created with your lost/borken Trezor device. Follow these instructions for Trezor One and these for Trezor T

  3. Finally connect your new hardware device to your Green companion app, like you’ve always done

Option 2 - Emergency restore via software signer

If you cannot buy a new Trezor device and yet you need to move funds locked on your Green multisig wallet, you can restore the recovery seed originally created on your Ledger device onto your Green companion app.

Caution

This method ensures access to any funds, but decreases the security of the keys you once stored on your hardware wallet. If you need to use this method, we suggest you move your funds back to a new reasonably secure wallet setup as soon as you are out of your emergency situation.

  1. Get the recovery seed you originally created with your lost/borken Trezor device

  2. Select the correct network, Bitcoin or Liquid

  3. Tap on Restore Green Wallet and use your Trezor recovery seed to proceed. During this process Green will prompt you to create a PIN to quickly access your wallet, after that you will gain access to your funds

  4. You can now move these funds onto a new wallet, or access your wallet via the PIN set at step 3
