Some etiquettes of Blockchain you need to follow for security purposes.

1) Turn On MEV Protect on DEX before taking trades – Keeps front running bots away.

2) Always Label your Frequently Sent / Received Address in Wallets – Prevents Address Poisoning attacks.

3) Don't interact with $0 tokens that are randomly sent to your wallet. You can see these transactions on explorer. Just ignore. Someone's trying to poison your wallet – Only import tokens that you're familiar with. Rest are hidden in wallet.

4) Never Ever Share your Private Key or Seed phrase – Once leaked, consider your account will be drained for sure. Hackers don't spare anything!
