How to Buy and Sell Bitcoin with Unchained's Multisig Vault


Unchained offers a secure and simple way to trade Bitcoin from your multisig vault. To get started, you need an approved Unchained account, a multisig vault with hardware devices, and a linked bank account. If you require assistance with setting these up, Unchained's support team is available to help. This guide walks you through the process of buying and selling Bitcoin directly from cold storage while maintaining control of your keys.

Preparing Your Account


  1. An approved Unchained account
  2. A multisig vault set up with hardware devices
  3. A linked bank account for transactions

Steps to Enable Trading

  1. Log in to your Unchained account and access the home dashboard.
  2. Locate the "Start Trading" button on the bottom left corner of the screen.
  3. Click "Start Trading" to reveal a checklist on the right side, outlining the requirements to enable trading for your account.
  4. Follow the checklist items and click on the provided links to navigate to the necessary pages.

Buying Bitcoin

Initiating a Purchase

  1. Once your individual account is enabled for trading, switch to it by selecting the account from the dropdown on the top left corner.
  2. The "Start Trading" button will change to "Buy" and "Sell" options.
  3. Click "Buy" to access the Buy Bitcoin screen.
  4. Note the current price and your available credit limit (default is set at $100,000).
  5. Observe the minimum ($2,000) and maximum ($100,000) trade amounts.
  6. Choose your desired transaction amount by toggling between USD and BTC denominations.
  7. Review the trading fees displayed under the transaction box.
  8. Select a specific vault or loan for the Bitcoin deposit using the dropdown menu.
  9. Click "Preview Buy" to review the transaction details.

Finalizing the Purchase

  1. On the next screen, a live price quote for your pending trade will be displayed. The price updates every few seconds.
  2. Carefully read the terms of service and ensure all transaction details are correct.
  3. Click "Execute Buy" to confirm the order. At this point, the price is locked in.
  4. Proceed to the wire instructions and wire deadline screen. This is where you'll receive the banking details for payment.
  5. Download your trade statement for your records.

After Purchase

  • Once Unchained receives your USD funds, the Bitcoin will be deposited into your vault, usually within two business days.

Selling Bitcoin

Initiating a Sale

  1. Navigate to the bottom left corner and click the "Sell" button to open the Sell Bitcoin workflow.
  2. Focus on the center of the screen, where the Bitcoin price and sell limit are displayed.
  3. To increase your sell limit, click the link and fill out the form provided.
  4. From the dropdown, select the vault you wish to sell from and the bank account where you want to receive dollars.
  5. Note the minimum and maximum trade amounts.
  6. Specify the amount of Bitcoin you want to sell, which must be in Bitcoin denomination.
  7. Select your two keys (e.g., Alpha and Bravo) for the transaction. If you lack access to one key, you can request Unchained to sign, but this will delay the process.

Finalizing the Sale

  1. Review the transaction details, including the automatically set mining fee rate.
  2. Click "Continue" to create an unsigned Bitcoin transaction and expand the information if needed.
  3. Begin signing the transaction with your first key (e.g., Alpha), verifying addresses and amounts on your hardware device.
  4. Once both keys have signed, continue to the broadcast transaction screen for a live price quote.
  5. Agree to the terms of service.
  6. Click "Execute Sale and Broadcast Transaction" to lock in your trade price and broadcast your transaction to the Bitcoin network.
  7. Download your trade statement on the summary screen.

After Sale

  • The "Sell in Progress" button will remain until the Bitcoin confirms on the blockchain, reverting back to a blue sell button afterward.
  • No further action is required; once the confirmation is on the blockchain, USD funds will be sent to your linked bank account, typically within two business days.
