BTC.com wallet and the Segwit2x hard fork

Segwit2x, a bitcoin hard fork, will take place on or around November 18 — or, more precisely, when block 494,784 is mined. With a few weeks to go until the fork, we would like to give our wallet users a clear overview of our plans for the occasion.

BTC.com’s wallet aims to empower bitcoin users with exclusive control of their funds, as well as in making transactional decisions. As we did with August’s Bitcoin Cash hard fork, the BTC.com wallet will enable users to transact on both side of the bitcoin blockchain after the November Segwit2x fork. Both networks will be seamlessly integrated into the BTC.com wallet interface, making it convenient for you to transact securely.

Built-in replay protection

Moreover, we have gone through great efforts to ensure that BTC.com wallet users will benefit from wallet-side protection from replay attacks. Wallet users’ transactions will be secured from being replayed (or rebroadcast) on both chains, a scenario which can cause a loss of funds while using wallets from organizations that have not taken this precaution.

We believe offering wallet-side replay protection is a crucial step toward providing a product that is more secure to transact with, and is a proactive solution to the evolving practical needs of cryptocurrency users.

What should you do?

If your funds are stored using the BTC.com wallet, you do not have to take any additional action — you will be able to access both networks, and will automatically enjoy replay protection over funds stored in your wallet. As for other services you use to store bitcoin, we recommend you verify with your wallet or exchange provider your ability to transact on both networks, as well as your security from transactional replay attacks.

For the best fork experience, we recommend holding funds using BTC.com wallet before the hard fork. This will allow you to fully benefit from replay protection for all post-fork transactions.

As a reminder, for your security, please remember to enable two-factor authentication in your wallet, and make sure you have securely saved your wallet’s backup sheet (PDF file).
