Did you store Bitcoin (BTC) in a Trezor hardware wallet before August 1, 2017? If so, you already possess an equal number of Bitcoin Cash (BCH) coins. The Bitcoin blockchain experienced a hard fork on August 1. When that occurred, Bitcoin’s blockchain was essentially split in two. The original Bitcoin blockchain now exists along side a new, separate Bitcoin Cash blockchain. Before the fork, both blockchains are identical. As such, the private keys that secured your Bitcoin in Trezor before August 1 also allow you to claim Bitcoin Cash with Trezor today.
The Bitcoin Cash blockchain has replay protection. This allows you to claim Bitcoin Cash even if you moved or spent your Bitcoin since August 1 as long as you still possess your pre-fork private keys. Claiming your BCH does require a Trezor firmware update. Before updating your Trezor firmware, make sure you have your recovery seed words available. You may need them to recover the digital assets stored on Trezor in the unlikely event of a firmware update failure. If you want to claim Bitcoin Cash with Trezor, follow the steps below.
Update your Trezor firmware
To embark upon the Bitcoin Cash claiming process, update your Trezor to the latest firmware version (1.5.1 or later). Visit Trezor Wallet to download the firmware update.
Connect your Trezor, then input the PIN. At the top of the page, locate the New TREZOR firmware is available message. Click the Show details button to proceed.
Review the information in the Your device firmware is outdated window. Once you have read it and understand it, click the Close button to continue.
Disconnect Trezor from the USB cable. While pressing both buttons simultaneously on the front of your Trezor, re-connect it to the USB cable. Carefully read the information in the Update device firmware? window. Click the Yes, update button when you want to proceed.
Trezor will update with the new firmware. You may need to click the right-hand button on Trezor to Confirm.
When prompted, confirm the firmware fingerprint by pressing Continue on your Trezor.
If the update was successful, disconnect Trezor. If the firmware update was not successful, return to Step 1 and try again.
Claim Bitcoin Cash (BCH) to Trezor’s BCH Wallet
With the latest firmware version installed, visit Trezor Wallet. Connect Trezor, and input your PIN. Pull down the Wallet menu, and select Bitcoin Cash (BCH).
Click the Receive tab, and copy a fresh Bitcoin Cash Receive payment address. Click the Show on TREZOR eyeball icon to verify the address.
Next, in the message box at the top of the wallet, locate the coin-splitting tool link.
In the Claim your Bitcoin Cash (Bcash) window, click the Connect with TREZOR button.
Review the information in the Claim Bitcoin Cash to your wallet window. Pull down the ACCOUNT menu, and choose an account where you stored Bitcoin. Paste the BCH receiving address you copied from your BCH wallet into the TARGET ADDRESS field. Click the Claim xxx.xx BCH button.
Check the BCH recipient address on the Trezor display. If it matches your BCH receiving address, press the Confirm button. Press the Confirm button again to finish the transaction. Repeat the steps if you have additional accounts that contain pre-fork Bitcoin.
Return to the Trezor BCH Wallet. Your claimed BCH displays under the designated account number.
