Bitcoin Cash hard fork and reply protection
On November 15 2018, Bitcoin Cash was hard-forked and split into two separate chains, Bitcoin Cash (BCH) and Bitcoin SV (BSV). These are two different and non-compatible blockchains with two different teams that follow their own rules. However, there is no replay protection between them. It means that either of your BCH or BSV transactions will be available on both chains simultaneously (double-spend).
To prevent that, you need to split BCH from BSV before sending money. Splitter tools mix each of your transactions with a special one. This measure helps make each transaction unique and prevent networks from simultaneous broadcasting.
How to split your BCH/BSV?
Coin Wallet doesn't provide a splitter tool. To split BCH and BSV, you need to do the following:
- Open Coin Wallet and search BCH and BSV.
- Open your account on an exchange that supports both forks (Binance, Poloniex, Kraken etc).
- Send either BCH/BSV from your Coin Wallet address to your exchange wallet address. Once sent, you will see both currencies gone.
- Once the transaction is complete, you will see both currencies deposited to your exchange wallet address.
- Withdraw either of BCH or BSV back to your Coin Wallet address. You will see the currencies going separately.
Once withdrawn, you can use these coins separately from your Coin Wallet.
Important: Bear in mind that if someone sends you unsplit coins, your BCH and BSV might get split again. In that case, you will have to repeat the procedure.
If you didn’t split your BCH/BSV coins the double-spend error may occur. You may find both coins to be gone if you performed an exchange with one of them. For example, your exchange BSV-BTC, but also your BCH is gone. If that’s the case, please contact our support or exchange partners about the exchange. They will make a refund. However, the refund may take 2 weeks and longer. Be careful and make sure your coins are split before making operations with them.
