1. Common Crypto Scams in 2026

🔹 Wallet Drainers (Approval Exploits)

What it is: A scammer tricks you into approving a malicious smart contract, giving them permission to move tokens without stealing your private key.
Prevention:

• Always verify contract addresses

• Use revocation tools regularly

• Avoid signing messages blindly

🔹 Pig Butchering Schemes

What it is: A long-con scam where victims are befriended and convinced to invest in fake crypto opportunities.
Red Flags:

• High-return promises

• Pressure to invest fast

• Private social groups with “insider tips”

🔹 Fake Investment Platforms

How it works: Scammers mimic legitimate exchanges or DeFi projects to collect deposits and disappear.
Signs:

• Withdrawal issues

• Unclear company identity

• No verifiable trading history

🔹 Phishing & Impersonation

Method: Scammers impersonate official support on Telegram, Discord, X, or email.
Avoid: Clicking unknown links, downloading suspicious attachments, or giving seed phrases

How it happens: Approving a malicious contract allows attackers to spend your assets.

3. Immediate Steps After a Scam

1. Stop Using the Compromised Wallet – Never sign another transaction.

2. Do Not Send Recovery Fees – Many victims fall for secondary scams.

3. Preserve Evidence – Save tx hashes, wallet addresses, screenshots, and communications.

4. Trace the Funds – Blockchain data is transparent; tracing can show where funds moved.

Not all stolen crypto can be recovered. Recovery depends on:

• Whether funds reached a regulated exchange

• Assets still being in freezeable tokens (USDT, USDC)

• Funds not being mixed or swapped through privacy services

At Onchain Defender, we provide evidence-based assessments to clarify what’s realistically possible.
