Body: I learned this lesson the hard way back in 2023, and it cost me a few hundred dollars in gas fees and one very stressful afternoon. A friend sent me a link to claim an airdrop from a new DeFi protocol. I connected my main wallet, claimed the token, and never thought about it again. Three months later, that same protocol's frontend was compromised. Because my wallet still had an active connection, the attacker's site could prompt me to sign a transaction I never intended to approve. I caught it in time, but the panic was enough to change how I manage wallet permissions forever. Monthly checks are my baseline, but the real answer depends on how you use your wallet. If you only connect to a handful of well-known dApps like Uniswap, Aave, or OpenSea, a check every 30 to 45 days is enough. If you chase airdrops, test new protocols, or connect to NFT minting sites regularly, you should review connections every week. A single malicious connection is all it takes to drain a wallet, and the risk grows with every unfamiliar site you approve. Here is the routine I follow now, and it takes less than ten minutes. Start with a full permission audit Open your wallet's security or permissions page and treat it like a bank statement. In MetaMask, go to Settings, then Security & Privacy, then Connected Sites. In Phantom, look for Connected Apps under Settings. In Trust Wallet, the section is called WalletConnect. Write down or screenshot every dApp that has an active connection. You want a complete picture before you start revoking anything. Check each connection against your actual activity For every dApp on the list, ask yourself two questions. When did I last use this? Was it a one-time action or something I use regularly? If the answer is more than 30 days ago, or it was a one-time claim, swap, or mint, revoke it. You can always reconnect later. Revoking does not close your position in a liquidity pool or unstake your tokens. It only removes the dApp's ability to request transactions from your wallet. Look for anything you do not recognize This is the most important step. If a dApp name looks unfamiliar, or you see a connection you do not remember making, revoke it immediately. Scam sites sometimes use names that are close to legitimate projects, like a slight misspelling or an extra character. If you are not 100 percent sure what a connection is, cut it. No legitimate dApp needs a permanent connection to your wallet. Use a dedicated wallet for high-risk dApps I keep two wallets now. My main wallet holds the assets I care about and only connects to a short list of trusted protocols. My burner wallet is for testing new dApps, claiming airdrops, and minting NFTs from projects I have never heard of. If the burner wallet gets compromised, the damage is limited. I fund it with only what I need for that specific interaction. This single habit has saved me more times than I can count. Check after major events Protocol upgrades, market crashes, and high-profile exploits are all reasons to do an unscheduled check. When a major DeFi platform announces a vulnerability or a popular NFT marketplace gets hacked, malicious actors often create clone sites to exploit the panic. After any significant market event, I open my wallet permissions and look for anything new or suspicious. It takes two minutes and gives me peace of mind. What I skip and why I do not rely on third-party tools like Revoke.cash as my only line of defense. They are useful for a consolidated view of token approvals, but they are not a substitute for checking your wallet's native permissions page. Scam clones of Revoke.cash exist, and typing the wrong URL can create a new problem while you are trying to solve an old one. If I use a tool like that, I navigate to it from the project's official documentation or verified social media account, never from a search result. One more thing people forget: revoking a dApp connection is not the same as revoking token approvals. A dApp connection lets a site request transactions. A token approval lets a smart contract spend a specific token from your wallet. Both matter, but they are managed in different places. Your wallet's connected sites page handles the first. For the second, you need to check your token approval history on the relevant blockchain explorer or through a tool like Revoke.cash. I do both during my monthly review. The whole process takes less than ten minutes once you know what to look for. I do it on the first Sunday of every month, usually with coffee. It is boring, routine, and unglamorous. It is also the reason I still have the assets I bought back in 2021. A few minutes of maintenance beats a lifetime of regret.
