Recommended collection: These 10 tips are worth at least $1 million. The most complete guide to preventing theft of encrypted wallets in history. Hello everyone, I am Brother Bird. Today, a disciple lost his wallet and lost a lot of assets. This is not the first time he has been stolen, so I think it is necessary to share my experience in preventing theft in the past two years. It may help you recover millions of dollars in assets, which can be regarded as a kind of good deed. So far, we have been doing airdrops for 3 years and have thousands of wallets, and we have not lost a single one. The following methods are purely personal experience. If you have any supplements, please post them in the comment area. Everyone will thank you! You can talk to Brother Bird about how to batch airdrops.

1. Close the browser clipboard. Close the clipboard in the Chrome browser; chrome://settings/content/clipboard  

2. Copy the mnemonics and private keys in segments; when copying the mnemonics and private keys, you can paste and copy them in 3 segments to avoid the clipboard being intercepted; 

3. Regularly cancel the contract authorization, use the following website, currently only supports the ETH ecosystem; https://revoke.cash/zh  

4. Upload the private key mnemonics information to Google Drive; we have at least several thousand wallets. For the convenience of management, you can upload the table containing the mnemonics and private key account information to Google Drive for management. Although it is not 100% safe, it will definitely be safer than keeping it locally! https://drive.google.com/ 

5. Install the security detection contract browser plug-in; this plug-in can be used as an auxiliary tool to determine whether the contract is safe each time the contract is authorized; https://dash.pocketuniverse.app/ref/Y481

6. Install the genuine Windows operating system; some apprentices bought the pre-installed operating system in the second-hand computer before. The pre-installed operating system may be pre-installed with Trojans. It is recommended to download the genuine system yourself; 

7. Don’t install unfamiliar software. Needless to say, try to install software from large manufacturers. Unfamiliar software can be installed in a virtual machine or cloud operation; 

8. Install the castrated version of the Little Fox metamask wallet. Since we are a studio, we also need to "castrate" the wallet plug-in for employees. The so-called castration is to delete the export mnemonics and private key functions of the Little Fox wallet. Employees can only transfer money at most, but cannot master the private key. You can add my V: niaovip for free. Check the code security yourself. I am not responsible for security (anyway, we have used it for more than 2 years);

9. Use remote desktop behavior monitoring tools; this tool monitors employees' computers in real time, and can set time intervals to take screenshots of the desktop. If there is a problem, just use evidence to speak. I don't want to test human nature; it can also prevent employees from slacking off; https://www.monitask.com/  

10. Finally, I would like to remind everyone that there are many phishing websites on Twitter and other social media. They will imitate the official website of the project, and blue V and gold labels can also be purchased. Don't easily authorize websites that have not been strictly confirmed. There are often phishing websites in the Solana wallet. Don't click on NFTs airdropped by phishing websites. There will be no pie in the sky for no reason;
