#空投安全指南 In cryptocurrency airdrop activities, security is one of the most important aspects for users to consider. The following summarizes key measures to enhance security based on recent cases and industry experience:
I. Strictly verify the authenticity of airdrop projects
1. Verify the project background
Team and whitepaper: Confirm that the project team is open and transparent, and check if the whitepaper clearly outlines the technical roadmap, token distribution, and economic model. Be wary of anonymous teams or projects lacking detailed information.
Community activity: Observe interaction frequency and user feedback through official social media (like Twitter, Discord). Fake projects often lack genuine discussions or have a large number of bot accounts.
Audit report: Prioritize projects that have undergone third-party security audits. For example, the ZKsync airdrop contract vulnerability incident resulted in a loss of $5 million due to insufficient auditing.
2. Be wary of high-yield promises
Fake airdrops often tout 'zero cost, high return', such as requiring deposits of ETH to exchange for 'thousand-fold tokens' or inducing users to authorize transfer permissions. Any airdrop that asks for private keys, seed phrases, or prepayment fees is a scam.

II. Protect personal information and asset security
1. Use dedicated wallets
Create an independent wallet address for receiving airdrops to avoid mixing with main assets. Recommended are hardware wallets (like Ledger) or non-custodial wallets (like MetaMask), and ensure they are downloaded from official channels.
Avoid binding your main wallet on unknown platforms to prevent malicious scripts from stealing permissions. For example, the Airgrab scam stole assets through the authorization transfer function.
2. Handle privacy data with care
Only provide necessary personal information (such as email, wallet address), and avoid disclosing identification or sensitive data. Some fake airdrops collect information to implement phishing attacks.

III. Avoid high-risk operations
1. Be cautious of links and contract interactions
- Obtain airdrop links only through official announcements or trusted aggregation platforms (like CoinGecko). Check domain name spelling before clicking to avoid counterfeit websites.
- Before interacting with smart contracts, use tools (like Etherscan) to review contract code and confirm there’s no malicious logic. For instance, some airdrop contracts hide backdoors allowing hackers to mint tokens.
2. Avoid using VPNs to bypass geographic restrictions
- U.S. users are often excluded from airdrops due to regulatory restrictions, but using a VPN may trigger platform risk control, leading to account bans or asset freezes. Weigh risks against rewards.

IV. Use tools and strategies to reduce risks
1. Enable multi-factor authentication (2FA)
- Enable two-factor authentication for wallets and exchange accounts to prevent unauthorized access. It is recommended to use Google Authenticator or hardware keys.
2. Diversify participation in high-potential projects
- Choose protocols with high TVL (Total Value Locked) and a moderate user base (such as Babylon, Resolv Labs), and distribute investments to reduce single-point risks.
- Pay attention to changes in point rules and adjust strategies in a timely manner. For example, the cross-chain liquidity contribution points of the BOB Protocol directly affect token distribution weight.

V. Post-event monitoring and response
1. Track asset dynamics in a timely manner
- Monitor wallet transaction records via blockchain explorers (like Etherscan), and immediately freeze addresses or transfer assets upon discovering abnormal transfers.
2. Response measures after encountering scams
- If a private key is leaked, immediately transfer remaining assets to a new wallet and change all associated account passwords.
- Report scam links to the platform and share cases within the community to warn others.

Summary: Security first, rational participation
While airdrops may bring profits, they come with both risks and opportunities. Users must balance 'fear of missing out' (FOMO) with security, prioritizing projects with strong compliance and high transparency. For example, the Babylon airdrop balances token distribution through DAO governance, while the multi-layer encryption technology of the XBIT exchange provides security for asset circulation. Continuously learning about security and staying vigilant is key to long-term participation in the crypto ecosystem.
