How to protect yourself?
Let's be honest: if you got hacked, it's almost always your own fault. Harsh, but I've seen people lose everything because they clicked one wrong link or signed one bad transaction. No tool will save you from yourself, but these tools make it much harder to screw up.
Start with your wallet. Switch to Rabby if you haven't yet. It simulates every transaction before you sign it and shows you exactly what will happen in plain language. It also has a built-in Approvals tab where you can revoke old permissions, same as RevokeCash but right inside the wallet. Install PocketUniverse on top of that and you've got two layers catching phishing and drainer contracts before they touch your funds.
Keep your serious money cold. Get a Ledger or Trezor for anything you're not actively using. Yes, plugging in a USB every time is annoying. But it's way less annoying than watching your savings disappear. If it's team funds or really serious money, set up a Safe multi-sig so no single key can drain the wallet.
Passwords and 2FA are not optional. Use BitWarden (free, open source) or 1Password ($3/mo). Unique password for every site, no exceptions. Enable 2FA everywhere with Authy (has cloud backup, so if your phone dies you don't lose all your codes). Never use SMS for 2FA, SIM swaps are real.
Before buying any new token, check it on HoneyPot (can you actually sell after buying?), RugCheck (Solana tokens), or Token Sniffer (EVM tokens). Takes 10 seconds and could save you from a rug pull.
And please: bookmark the sites you use. Don't Google "Uniswap" and click the first link. Keep your seed phrases offline, not in Notes, not in Telegram saved messages. Separate your main wallet from farming wallets completely. And for the love of Satoshi, don't flex your portfolio on Twitter with your real identity.
