Airdrops can introduce you to useful projects, but a listing, points balance or social badge is not proof of safety or a promise of payment. Check the project's current rules yourself. This guide is education, not a guarantee against loss.

Before you participate

Check the destination, not just the logo

A familiar name, polished page or HTTPS padlock does not establish legitimacy. Bookmark sites you have verified. Compare announcements across the project's official website and established channels before following a new claim link. Search ads, reply threads, QR codes and unsolicited messages can lead to lookalike sites. Even an established social account can be compromised.

A free signature can still grant permissions

Signing a message without paying gas is not automatically harmless. Some off-chain signatures, including permits and NFT orders, can authorise spending or transfers later. Inspect the requesting domain, network, spender, assets, amount and expiry where your wallet displays them. Do not blind-sign data you cannot understand. Reject requests that do not match the action you intended, and do not dismiss a wallet warning simply because a site asks you to.

Review token approvals and other permissions

Use the smallest spending limit that fits the action when possible. Review unused allowances with your wallet's official tools or your network's verified block explorer. Disconnecting a site does not cancel its existing token approvals. Revoking an on-chain allowance normally costs gas and cannot undo a transfer that has already happened. Permissions work differently across networks; check the wallet's own guidance.

Ignore unexpected tokens and NFTs

An unsolicited token, NFT, voucher or tiny transfer may contain a link to a fake claim or swap page. Do not follow instructions in its image, description or transaction message. A displayed value does not prove you can sell it. Hide suspicious assets using your wallet's built-in controls rather than visiting a site to unlock, burn or cash them out.

Check the entire receiving address

Do not copy a receiving address from an unfamiliar transaction in your history. Address-poisoning scams use lookalike addresses to exploit checks of only the first and last characters. Obtain the address from a trusted source, verify the full address after pasting, and confirm the network and any required memo or tag before transferring.

Keep devices and accounts secure

Install wallets and extensions through verified official sources and keep them updated. Avoid unknown APKs, browser extensions, remote-access tools and commands supplied by strangers. Use unique account passwords and two-factor authentication where available. Never share login codes or approve an unexpected device login. Back up wallet recovery information offline in a safe place; hardware wallets do not make malicious signatures safe.

Understand the costs and project risks

Points may never become tokens. Allocation, eligibility and deadlines can change. Testnet participation does not guarantee mainnet rewards. Transactions and bridges may involve fees, contract risk and network-specific requirements. Treat deposit demands, urgent unlock payments and promised returns as reasons to stop and verify. Understand any legitimate participation costs before committing time or funds.

If something feels wrong

Stop interacting and reject new requests. Verify help through your wallet or project's official website. For suspicious permissions, review and revoke them using trusted tools. If a seed phrase or private key was exposed, treat that wallet as compromised: on a trusted device, follow the wallet provider's recovery guidance and move remaining assets to a new wallet with a new recovery phrase. If malware or an active draining script is suspected, get verified support before sending more gas into the affected wallet. Save transaction hashes and report the incident to relevant services and authorities. Be wary of anyone demanding payment to recover stolen crypto.

How to read FreeAirdrop labels

Potential, Confirmed, Testnet and Claim Live describe a project's reported status; they are not safety ratings or guaranteed eligibility. Active means the campaign is marked available; Needs review means availability needs checking; Ended means participation has closed. Historical articles may contain old instructions. Featured or sponsored placement is not a security audit. We do not need your seed phrase or private key to read a guide. Report a suspicious link or correction.
