🛡 Don't let your wallet become an open door | Regularly checking 'Approval' is the key to self-protection!

Another painful case: a user lost over $900,000 due to a phishing contract approval that was not revoked 458 days ago.

This was not a hacker attack, nor was your password cracked—rather, it was your own 'Approve' that you clicked, leaving an open door to your wallet.

🔍 What is Approval?

When interacting on-chain (such as using DEX, staking platforms, NFT markets, etc.), you are often required to 'allow the contract to operate your assets'. This authorization remains effective as long as you do not revoke it, allowing the other party to transfer your approved assets at any time.

🚨 Sources of risk:

• Phishing authorizations from fake websites (e.g., disguised as well-known platforms)

• Airdrop traps (as long as you've interacted with their contracts)

• Old approvals that have not been cleared for a long time (many people have never cleared them)

🧯 What to do? Three steps for self-protection:

1. 🔗 Go to the following tools to check approvals:

• https://revoke.cash

• https://app.safe.global (Safe Multisig)

• https://etherscan.io/tokenapprovalchecker

2. ❌ Revoke any contract approvals you no longer use or that are of unknown origin.

3. 📆 Check once a month, especially after participating in airdrops, using new platforms, or testing networks!

Don't let a single unintentional click lead to a lifetime of regret. In the on-chain world, there is no 'bank customer service'; you can only rely on yourself.

Regularly reviewing approvals is the survival rule for every Web3 user.
