Every airdrop claim asks you to connect a wallet to a site you have not fully vetted, and even careful users occasionally approve something they should not have. A burner wallet solves this by isolating the risk: if anything goes wrong, the attacker reaches an almost-empty wallet while your main holdings stay untouched.

Create a fresh wallet with its own recovery phrase, separate from your main wallet, using a reputable wallet app or a hardware wallet's secondary account. Write the new recovery phrase on paper and store it safely, but understand its role: this wallet is disposable, and you should never move long-term savings into it.

Label it clearly in your wallet app so you never confuse it with your main vault. Some users keep the burner as a browser-extension wallet and their savings in a hardware wallet, which creates a natural barrier. The separation is the entire point, so resist the temptation to reuse the burner for storage later.

Send only small amounts of gas money to the burner, enough for a few transactions, and top it up only when you plan to claim. When a legitimate airdrop lands, move the tokens to an exchange or your main wallet the same day rather than letting them accumulate in the burner.

Use the burner for all experimental activity: testnet claims, new protocol interactions, and airdrop forms. If a site behaves strangely or a signature looks wrong, you can abandon the wallet entirely and start a new one at almost no cost. That freedom to walk away is exactly what main-wallet users lack.

After each claim session, open your wallet's connected-sites list and disconnect anything you no longer use. Review token approvals on a revocation tool and remove unlimited approvals for contracts you do not recognize. These two habits take five minutes and close the most common paths attackers use weeks after the original claim.

If you ever suspect a burner wallet is compromised, stop using it immediately and create a fresh one. Do not try to rescue it or pay anyone offering recovery services, since recovery offers are a common second scam. A burner wallet is cheap to replace, and replacing it is always the safer move.

Consider running two burner wallets rather than one: a testnet burner for free trials and a mainnet burner for real claims. Testnet activity is harmless by nature since the tokens have no value, but it still trains the habit of connecting to unfamiliar sites. Keeping it separate from any wallet that ever touches real funds adds a layer of protection.

Label each wallet clearly with its purpose and never move mainnet assets into the testnet wallet, even temporarily. Cross-contamination defeats the separation you built the system for. If you later decide a testnet project deserves mainnet attention, evaluate it fresh through your mainnet burner rather than reusing testnet credentials or addresses.

Back up both burner recovery phrases, but store them separately from your main vault backup and mark them as low-value. If a burner phrase leaks, the damage is limited to whatever small balance and approvals that wallet holds, which is precisely the design. Replace any burner wallet the moment you suspect exposure, without hesitation or cleanup attempts.

Review your burner wallets monthly and retire ones tied to finished campaigns. Old wallets with lingering approvals are a quiet risk, and a short monthly cleanup keeps your attack surface small. Good wallet hygiene is mostly about reducing the number of forgotten connections, not about any single dramatic security step.
