🚨Have you ever heard about "replay attack"? I've been one's victim. 🚨
After 10 years, I finally remembered the password to my Bitcoin wallet. 🎉 Since I held Bitcoin for so long, I also owned its various forks like Bitcoin Cash ($BCH ) and eCash ($XEC ). Naturally, I wanted to consolidate everything into a multi-platform wallet.
As part of this process, I sent my XEC from Electrum ABC to Binance. Everything seemed fine... until 10 minutes later, when I discovered something shocking in my Electron Cash wallet: my BCH balance was gone! 😱💸
This was a classic replay attack. Let me explain:
1. When a blockchain undergoes a hard fork (like Bitcoin splitting into Bitcoin Cash), both chains share the same transaction history up to the split. 📜
2. Transactions valid on one chain can sometimes be replayed on the other chain if proper replay protection isn’t implemented. 🔁
3. In my case, when I sent XEC (eCash) from one wallet, the exact same transaction—same amount, same fee, same hash—was broadcasted on the BCH network. This caused my BCH to be sent to an unintended address. 😓 Perhaps. it should be binded to the same privatekey as XEC address.
Unfortunately, #binancesupport couldn’t help recover my BCH because the recipient address wasn’t under their control. Thankfully, it was only one buck, but it could’ve been much worse! 💔

If you are more advanced in crypto you can tell me if there is some way to reverse it. I don't suppose so. Anyway, I had emotional bond to my first crypto ever.
