Last week, one of my teachers almost lost his private key to his crypto wallet.
The cause of the incident was that the browser plug-in of the OKX wallet suddenly crashed during use, and Chrome popped up a prompt asking to "repair the extension" (many people should have encountered this situation, Metamask and other wallets will also have this kind of problem). After clicking confirm, Chrome accidentally reinstalled the wallet and cleared the plug-in cache.
At this time, the wallet is like it has just been installed, and the mnemonic must be re-imported to restore it. If there is no backup in advance, the wallet and the assets in it will be lost forever.
Fortunately, this teacher is usually very cautious and made multiple mnemonic backups in advance and saved them separately. However, when he entered the mnemonic, an accident happened: the wallet prompted that the mnemonic format was incorrect and could not be successfully imported.
After re-entering it several times, the plug-in still prompted that the mnemonic was incorrect. Although the teacher was a little panicked, with solid blockchain knowledge, he initially judged that he copied the wrong words or copied them in the wrong order when backing up the mnemonic. He tried to write a script to recover by exhaustive method (replacing the mnemonic), but the first attempt was unsuccessful.
I helped contact @Haiteng_okx of OKX wallet and confirmed that the wallet could not be recovered by restoring the plug-in cache (mechanical hard disk may have a chance, but SSD is basically out of the question), so the most promising solution is still to repair the mnemonic error.
Finally, after fixing a small bug in the script, the wrong mnemonic was successfully restored (one letter was copied wrong), and the wallet was successfully restored, and everyone was happy.
What can we learn from this incident?
The teacher's two summaries are worth remembering:
1. Disaster recovery measures should be practiced, not just on paper
The mnemonic of this wallet was backed up, and multiple copies were made and placed in different locations. However, there was no attempt to restore the wallet through the mnemonic, but only to compare the correctness of the mnemonic with the naked eye. At that time, I thought it was copied correctly, but in fact there was a letter wrong. If you try to restore the wallet with this mnemonic, you will find that the backup is wrong.
2. Details determine success or failure
Originally, a situation like this where only one word is remembered wrong can be easily repaired. However, the repair program did not consider the difference between uppercase and lowercase Ethereum addresses, and mistakenly thought that it was not found.What could have been done in a few minutes ended up taking 3 days, causing a lot of psychological pressure.
My suggestions
1. After backing up the wallet mnemonics, be sure to check whether the wallet can be restored correctly.
2. When the wallet browser plug-in crashes, do not click to repair easily. You need to back up the plug-in cache first.
3. If the mnemonic backup is incorrect, don't panic. It is likely that 1~2 digits of the mnemonic were copied incorrectly. You can try to restore it through the recovery software. I recommend the open source: btcrecover

Safety is no small matter. I hope everyone can keep their wallets properly and don't let the hard-earned assets disappear due to operational errors!

Is a valuation of 4 billion for Pump high?
Although it's quite foolish for Pumpfun to seek to raise 1 billion at a 4 billion valuation, having already made so much money, who can refuse more money?
From the monthly revenue of the protocol, Pump's revenue in the past month was 70 million, slightly lower than Hyper (4B FDV) and Uni (6.6B FDV), so a valuation of 4 billion seems reasonable.
Additionally, considering there will be a 10-20% airdrop, which means 500 million to 1 billion going to the young players, it feels okay?
