How to protect yourself from fraud in Web3?

It is your duty to protect yourself from fraud, as because of blockchain specifics it is very hard to return stolen funds.

1. Never share the secret phrase (seed phrase) or private key with anyone. Whoever has this key can control the wallet and all funds in it. You can't change the key and use the same wallet safely. If you are concerned your key was compromised, it is better to create a new wallet with a new key and transfer all funds to it.
2. Use only recommended wallets for working with Tonstakers or other TON apps. New wallets with a small user base might have backdoors or exploits.
3. Do not click any links promising free tokens, airdrops, or NFTs, especially if the links are provided by some famous person. Hackers love to hijack famous accounts and scam people.
4. Do not trust anyone who's writing your first, especially if they call themselves Tonstakers team members or other TON apps members. Tonstakers team won't write your first!
5. Take into account only what you see in official channels, for example in Tonstakers Telegram channel.

And finally — trust no one, do your own research (DYOR). Blockchains and transactions are transparent for this purpose.
