Understanding the August 1st Hard Fork and Chain Split
On August 1st, 2023, a segment of the Bitcoin community implemented a non-compatible network upgrade, increasing the block size limit to 8MB and removing Segregated Witness (SegWit). This "hard fork" resulted in a chain split, creating two distinct currencies: Bitcoin (BTC) with SegWit activation and Bitcoin Cash (BCH).
As a TREZOR user, your private keys remain secure, and no immediate action is required unless you wish to access your Bitcoin Cash (BCH) holdings post-fork. Below is a detailed guide to navigate this event safely.
Key Actions for TREZOR Users After the Fork
1. Claiming Your Bitcoin Cash (BCH)
Bitcoin Cash implemented replay protection, ensuring safe transactions. TREZOR Wallet provides a dedicated interface to claim BCH:
- Select Bitcoin Cash (BCH) in the currency dropdown.
- Follow the prompts to transfer BCH to a new BCH-specific address.

2. Address Management
- BCH uses a separate derivation path:
m/44'/145'/. - Never send BTC to a BCH address or vice versa.
Note: No action is needed for the original Bitcoin (BTC) chain.
Bitcoin Cash (BCH) in TREZOR Wallet
- Labeled as BCH (some services may use "Bcash" or "BCC").
- Requires firmware updates for full compatibility.
FAQs
1. What is replay protection?
BCH added a unique transaction format to prevent replay attacks, making its transactions invalid on the Bitcoin network.
2. Are BCH addresses different from BTC addresses?
Yes. BCH addresses derive from your seed but use a distinct path (m/44'/145'/).
3. Why do I need to "claim" BCH?
To separate BCH from BTC holdings, ensuring each currency resides in its designated address for security and privacy.
