  1. Common Types of Crypto Scams

  2. Impersonating Customer Support or Official Staff

Scammers often pretend to be:

  • Exchange customer support

  • Project team members

  • Regulators or “security audit departments”

  • Airdrop administrators

Typical scam messages include:

  • “Your account has an issue and needs verification.”

  • “A large transfer is frozen. Please provide your verification code.”

  • “We can upgrade your account permissions for you.”

  • “Send me your seed phrase so I can help recover your funds.”

⚠️ No official representative will ever ask for your password, verification code, private key, or seed phrase.


Scammers create fake pages such as:

  • Fake exchange app download pages

  • Fake airdrop portals

  • Fake “Connect Wallet” pages

  • Fake announcement or event pages

Their goal is to trick users into:

  • Entering seed phrases

  • Signing malicious smart contracts

  • Authorizing unlimited token approvals

Common red flags:

  • Domains that look similar but slightly altered

  • Urgent prompts like “Authorize Now” or “Upgrade Immediately”

  • Requests to sign unknown permissions such as unlimited approvals


  1. Social Engineering Scams (Telegram / Discord / Twitter)

Scammers may DM you directly, claiming to:

  • Help with trading issues
