What is a Web3 airdrop?

A Web3 airdrop is a marketing strategy where blockchain projects distribute free tokens to users. Projects use airdrops to attract attention, test product features, and build communities. Users typically need to complete simple tasks like following social media accounts or using the product.

How to participate in airdrops?

To participate in airdrops, you typically need: 1) A supported digital wallet; 2) Complete tasks as required (e.g., follow Twitter, join Discord); 3) Submit your wallet address; 4) Wait for token distribution. Requirements may vary between projects.

What security issues should I watch out for?

Important security tips: 1) Never share your private key or seed phrase; 2) Don't connect to untrusted dApps; 3) Be cautious with token approvals; 4) Verify official project websites and social media; 5) Beware of phishing sites and fake airdrops; 6) Use a dedicated airdrop wallet.

Which wallets are recommended for airdrops?

Recommended wallets: MetaMask (most versatile), Trust Wallet (mobile-friendly), Phantom (Solana ecosystem), Keplr (Cosmos ecosystem). It's recommended to create a dedicated airdrop wallet separate from your main wallet to reduce risk.

How to create multiple wallet addresses?

You can create multiple accounts in the same wallet app or use different wallet apps. Note that each address requires separate private key management, and backups are recommended. Some projects may restrict users from using multiple addresses.

How to find quality airdrops on the platform?

You can filter quality airdrops by: 1) Checking project ratings and community reviews; 2) Reviewing project background and team info; 3) Analyzing token economics; 4) Checking the project roadmap; 5) Monitoring community activity; 6) Referencing other users' participation.

How to set up reminders and follow features?

The platform offers multiple reminder options: 1) Airdrop start/end reminders; 2) New airdrop push notifications; 3) Project status updates; 4) Personal participation records; 5) Earnings analytics. Customize reminder preferences in your settings.

When can I trade airdrop tokens?

Trading time depends on the project's arrangement: 1) Immediate trading (tokens already listed on exchanges); 2) After lock-up period; 3) Gradual release; 4) Requires completing additional tasks to unlock. Check official project announcements for specific timelines.

How to evaluate the potential value of an airdrop?

Key evaluation points: 1) Project's technical innovation and practicality; 2) Team background and funding; 3) Market demand and competition; 4) Token supply and distribution mechanism; 5) Exchange listing plans; 6) Community building and marketing strategy.

What if I didn't receive tokens after participating?

Possible causes and solutions: 1) Check if all participation requirements were met; 2) Verify your wallet address is correct; 3) Check the project's distribution schedule; 4) Verify your wallet supports the token; 5) Contact project support; 6) Check community discussions for other users' experiences.

Web3 Security Protection Guide

In the Web3 world, you are your own bank. Learn how to build a multi-layered security defense system.

High-Risk Threats

Common threats: Private key leakage, seed phrase theft, phishing scams, malicious smart contracts
Potential impact: May result in total asset loss
Prevention: Absolutely avoid, strengthen basic security measures

Medium-Risk Threats

Common threats: Over-authorized dApps, unknown airdrops, social engineering attacks, public WiFi risks
Potential impact: May result in partial asset loss
Prevention: Operate cautiously, regularly check and revoke authorizations

Low-Risk Threats

Common threats: Weak passwords, device loss, software vulnerabilities, network eavesdropping
Potential impact: Increases attack risk
Prevention: Improve security awareness, use best practices

Step 1: Wallet Security Basics

Establish a solid wallet security foundation.

Download wallets from official channels, verify digital signatures
Create strong passwords: at least 16 characters with uppercase, lowercase, numbers, special characters
Handwrite seed phrase backups, use metal plates for long-term storage
Create multiple wallet addresses to diversify risk

Store large assets in hardware wallets, use hot wallets for daily operations

Step 2: Network Environment Security

Ensure secure network connections and browsing environment.

Use trusted network connections, avoid public WiFi for wallet operations
Enable VPN service to protect network privacy and security
Use the latest browser version, update security patches promptly
Install ad blockers and anti-malware extensions

Consider using a dedicated browser profile for Web3 operations

Step 3: dApp Connection Security

Safely interact with decentralized applications.

Carefully check dApp domains and SSL certificates
Read and understand details of each transaction
Limit token authorization amounts, avoid unlimited approvals
Regularly check and revoke unnecessary dApp authorizations

Use tools like Revoke.cash to regularly review and revoke dApp authorizations

Step 4: Transaction Security Verification

Ensure the security of every transaction.

Verify receiving address accuracy, compare first and last few characters
Check gas fee settings, avoid abnormally high fees
Confirm transaction type and contract address correctness
Use test networks or small amounts for initial testing

For large transactions, use hardware wallet for secondary confirmation

Step 5: Device & Software Security

Protect your devices and software environment.

Keep operating system and software updated
Use legitimate antivirus software and scan regularly
Regularly backup important data and wallet files
Avoid operating wallets on untrusted devices

Consider using dedicated devices or virtual machines for Web3 operations

Step 6: Social Engineering Protection

Identify and prevent social engineering attacks.

Be wary of private messages and investment advice from strangers
Don't share wallet addresses or transaction info on social media
Verify authenticity of official social media accounts
Learn to identify common scam techniques and scripts

Always remember: real customer service will never contact you asking for private keys

Step 7: Emergency Response Plan

Develop emergency response procedures for security incidents.

Prepare backup wallets for emergency fund transfers
Record important contract addresses and official contact information
Establish asset monitoring and anomaly detection mechanisms
Develop post-attack emergency response procedures

Regularly practice emergency procedures to ensure quick response in urgent situations

Myth: Not clicking suspicious links is enough

Reality: Attackers can use DNS hijacking, browser vulnerabilities, and other methods. Not clicking links alone is not enough. Multi-layered protection is needed.

Myth: Large dApps are always safe

Be cautious: Even well-known dApps may have smart contract vulnerabilities or be hacked. Always verify and limit authorization permissions before each interaction.

Myth: Hardware wallets are absolutely secure

Relatively secure: Hardware wallets greatly improve security, but still require proper use. Phishing sites can still trick users into confirming malicious transactions.

Myth: Anonymity equals security

Two concepts: Blockchain transactions are traceable. True security lies in protecting private keys and preventing various attacks, not relying on anonymity.

Wallet Compromised

Priority: Critical

Immediate actions:

Stop all operations immediately
Transfer remaining funds to a new wallet
Revoke all dApp authorizations
Change all related passwords

Strengthen security measures
Consider filing a police report

Suspected Malicious Contract Authorization

Priority: High

Immediate actions:

Do not attempt to transfer or trade the token
Do not interact with the token contract
Check token contract address
Check community discussions

Follow-up actions:

Wait for community confirmation
