Revoke Old Wallet Permissions for Safety
Posted: Tue Jun 17, 2025 2:39 pm
Every interaction with a DeFi platform often involves giving permission for that protocol to access your crypto wallet’s tokens. While this is necessary for transactions to work, many users don’t realize these permissions can last forever—even after you've stopped using the app.
This becomes a serious security risk.
If a protocol is compromised, attackers can exploit old token permissions to drain your wallet without needing further approval. You may think your funds are safe just because you're not active—but your open permissions say otherwise. Hackers often scan for wallets with unrevoked permissions as easy targets.
Fortunately, you can easily fix this.
Use tools like Revoke.cash, DeBank, or Etherscan Token Approval to view and revoke token approvals. These platforms show which apps have access to your tokens and let you revoke any that are unnecessary or outdated.
Make it a habit: periodically check your wallet and revoke unused permissions, especially for older dApps you no longer trust or use. Even popular wallets like MetaMask or Coinbase Wallet can be vulnerable if permissions are ignored.
This basic crypto hygiene step can save you from major losses—and it’s completely free. Revoke access after NFT trades, staking, or yield farming to stay safe.
Don’t let forgotten permissions become your weakest link. Stay proactive, stay secure.
