On November 15th, BCH(Bitcoin Cash) network successfully upgraded and adopted new consensus rules. This upgrade fork BCH out of two chains and a new token: BCHA(Bitcoin Cash ABC. Follow the steps below, and you will be able to claim your BCHA.

On November 15th, BCH network upgrade resulted in two separate chains: BCH and BCHA. This upgrade deployed the aserti3–2d difficulty adjustment algorithm (ASERT DAA) on BCH. The aserti3–2d DAA is simple to implement, well-tested, and extensively simulated. It incentivizes consistent mining, achieves stability for transaction confirmations with low-variance 10-minute block targets, and is resistant to future drift. This upgrade is the next step on the path of scaling BCH to be global, censorship-resistant, peer-to-peer electronic cash.

BTC.com monitored the hard fork, and as announced, BTC.com Wallet suspended all BCH transactions, as there is no replay protection on the BCHA chain. We re-enabled BCH transactions after adding a built-in replay protection feature in BTC.com Wallet.

If you own pre-forked BCH, you will now be able to claim the same amount of BCHA. Please read further down information to be able to extract your BCHA (1BCH = 1BCHA).

This step is mandatory, to enable you to safely extract your BCHA. This is a safe procedure, and your funds will remain in your Wallet as a new transaction. In the second part, we will extract your BCHA and send it to your BCHA address.
