As the cryptocurrency market expands, scam-related losses have become increasingly severe. According to reports by blockchain analytics firm Chainalysis, crypto-related scam losses reach tens of billions of dollars annually.

Among these, airdrop scams are one of the most common methods targeting beginners, as they cleverly exploit the psychology of "getting free tokens." Legitimate airdrops are a marketing method where new projects distribute tokens for free to increase awareness and grow their community — inherently a safe mechanism. However, scammers who abuse this system are relentless.

There are five main types of airdrop scams. Understanding each tactic will help you prevent falling victim.

Fake Airdrop Websites

This tactic involves creating fake websites that closely resemble official sites of well-known projects or exchanges, then luring users to visit them. The URLs often differ slightly from official domains, such as "uniswap-airdrop.com." These fake sites prompt wallet connections, and once connected, malicious smart contracts drain your assets.

Seed Phrase Requests

This tactic claims that "wallet verification is required to receive the airdrop" and asks you to enter your seed phrase (recovery phrase). Legitimate airdrops will never ask for your seed phrase. The moment you enter your seed phrase, all assets in your wallet are at risk of being stolen.

Dusting Attacks

This involves suddenly receiving small amounts of unknown tokens in your wallet. When you attempt to swap these tokens on a DEX (decentralized exchange), a malicious smart contract executes and steals approval (access permissions) to other assets in your wallet. It's crucial to never interact with unknown tokens.

Fake Token Grants

This tactic demands a small payment by claiming "send gas fees or processing fees first, and we'll send you a large amount of tokens." No tokens are delivered after payment, and your sent crypto is never returned. Legitimate airdrops never require upfront payments.

Fake SNS Accounts

This involves impersonating official project X (formerly Twitter) or Discord accounts and sending airdrop announcements via DM. These messages often contain urgency-creating phrases like "limited to X participants" or "today only," and the linked fake sites steal personal and wallet information.

When you encounter a suspicious airdrop, check the following five points.

1. Is there an announcement on the official website or official SNS?

Legitimate airdrops are always announced on the project's official website or official X (formerly Twitter) account. Airdrops communicated only through DMs or unofficial channels are very likely scams.

2. Does it ask for your seed phrase or private key?

Any airdrop that asks for your seed phrase or private key is 100% a scam. Under no circumstances should you provide this information to any third party.

3. Does it request excessive permissions (Approvals)?

If a wallet connection requests broad approvals like "allow access to all assets," it's dangerous. Legitimate airdrops only request the minimum permissions necessary for claiming.

4. Does the project have substance?

Check for a whitepaper, publicly disclosed development team, active community, and other indicators of project legitimacy. Airdrops from projects with unclear substance carry high risk.

5. Are the conditions realistic?

Offers claiming "anyone can receive tokens worth 1 million yen" are scams. Legitimate airdrop rewards are typically worth a few thousand to tens of thousands of yen.

If you unfortunately fall victim to a crypto scam, follow these steps immediately.

1. Move remaining assets to a safe wallet

If your seed phrase has been compromised, all assets in that wallet are at risk. Immediately create a new wallet and transfer your remaining assets.

2. Revoke unauthorized Approvals

If you granted Approval to a malicious smart contract, use tools like Revoke.cash to promptly revoke the relevant Approvals.

3. Disconnect your wallet

If you connected to a fake site, disconnect from that site through your wallet's settings.

4. Preserve evidence and consider filing a report

Preserve evidence such as transaction history screenshots, the counterpart's address, and communication records. While blockchain transactions are generally irreversible, consider filing a police report or consulting your local consumer affairs center.

With proper knowledge and precautions, airdrops can be safely utilized. Follow these guidelines:

• Trust only official information: Access only through links from the project's official website and official SNS, and bookmark them for safety.
• Use a dedicated wallet: Create a separate wallet specifically for receiving airdrops to minimize risk by isolating it from your main assets.
• Keep Approvals to a minimum: Always review the Approval details requested during wallet connections, and do not grant unnecessary permissions.
• Stay informed: It's important to stay updated on the latest scam tactics through reliable sources such as CoinGecko, DeFiLlama, and official Discord channels.
• Stay calm and judge carefully: Exercise caution with announcements using urgency-creating phrases like "limited" or "act now." Legitimate airdrops provide sufficient participation periods.

How can I spot an airdrop scam?

If it asks for your private key or seed phrase, requests wallet connection to an unknown site, or demands upfront payment — it's a scam. Always verify information on the official website and SNS.

What should I do if unknown tokens appear in my wallet?

Do not interact with them. This could be a "dusting attack" or "airdrop scam." Attempting to swap or transfer them may result in your wallet assets being stolen.

Can I recover funds lost to a scam?

Blockchain transactions are generally irreversible. Your top priority should be immediately moving remaining assets to a different wallet and revoking any unauthorized Approvals. Also consider filing a police report.

How do I find safe airdrops?

Follow three rules: verify announcements on official Twitter/Discord, choose projects formally listed on CoinGecko/DeFiLlama, and confirm that URLs match official domains.
