Protect Yourself from Wallet Drains, Phishing, Scams & Pig Butchering Schemes

Cryptocurrency fraud continues to evolve and so do the methods used by scammers. At Onchain Defender, our mission is to help you recognize, understand, and avoid the most common scam tactics in crypto  before you become a victim.

🛡️ Common Crypto Scam Types

🔹 Wallet Drainers (Approval Exploits)

This is one of the most frequent ways scammers drain wallets without overt hacking.

How it works:
You connect your wallet to a fake dApp or airdrop and approve a malicious contract. That approval gives the attacker permission to move your assets later — without any additional signature.

Prevention:

• Always verify the contract address you’re approving

• Use tools to revoke token approvals regularly

• If an app asks for “full access,” treat it as suspicious

---

🔹 Phishing and Impersonation

Scammers pose as official support on Telegram, Discord, X, or email.

They may use:

• Fake domain names

• Cloned websites

• Impersonated social accounts

• “Verified” badges that aren’t real

Don’t click links in DMs. Always manually navigate to official sites.

🔹 Pig Butchering Schemes

These are long con scams that start with small social interaction and end with large deposits.

How it works:
Victims are befriended, convinced to invest in an asset, then encouraged to deposit large sums. When the victim attempts withdrawal funds “fail to process,” the platform disappears, or support goes silent.

Warning signs:

• High-return promises

• “Insider” tips or private groups

• Pressure to invest quickly

---

🔹 Fake Investment Platforms

Websites that mimic legitimate exchanges or offer unbelievable APYs.

Red flags:

• No clear compliance information

• No real trading history

• Withdrawal issues

• Unclear company identity

Rule of thumb: If it looks too good to be true it is.

🔹 NFT & Token Approval Scams

Many scams begin with token approval — not sending funds.

Allowing a malicious contract to spend tokens is effectively giving the scammer access to your wallet.

Always audit approvals:
Visit revocation tools and remove permissions you don’t recognize.

Before interacting with a new platform:

🔍 What To Do If You Think You’ve Been Scammed

1) Stop Using the Compromised Wallet
Never sign another transaction from that address.

2) Don’t Send Recovery Fees
Many victims fall for recovery scams after being scammed.

3) Preserve Evidence
Save:

• Transaction hashes

• Wallet addresses involved

• Screenshots of chats

• Deposit receipts

4) Trace the Funds
Blockchain data is transparent. Tracing can reveal where the assets went even if recovery is not guaranteed.

🧠 Scam Prevention Checklist

Before signing anything:

✔ Is this the official project domain?
✔ Has the contract address been verified?
✔ Do you recognize the permissions you’re granting?
✔ Has anyone else publicly vetted this project?
✔ Has this platform ever paid withdrawals?
