Scam patterns

Crypto scam pattern database for approvals, presales, airdrops, and fake support.

Read recurring crypto scam patterns as operating checklists: what the scam looks like, the warning signs, and the defense before a wallet is connected.

Approvals

Wallet drainer approval pages

A fake mint, claim, presale, or airdrop page asks for broad token approvals or a malicious signature instead of a normal transaction.

  • Urgent claim window with no official source path
  • Signature request that does not clearly describe the action
  • Unlimited token approval for a site you do not already trust
Presales

Fake presale countdowns

A polished sale page uses stage pricing, fake scarcity, and social proof while hiding allocation, vesting, refund, or contract-control terms.

  • No clear token allocation table
  • Anonymous team with unverifiable roadmap claims
  • Payment flow asks for wallet connection before basic terms are readable
DEX tokens

Honeypot or blocked-sell tokens

A token can be bought but selling is restricted, taxed aggressively, or blocked by contract logic controlled by deployers.

  • Only influencer posts show successful buys
  • Contract has blacklist, pause, or fee-change permissions
  • Liquidity is tiny compared with promoted volume
Support scams

Impersonated exchange or wallet support

A fake support account asks for a seed phrase, remote access, verification payment, or a wallet connect session to solve a fabricated problem.

  • Support contacts you first
  • The account requests seed phrases or private keys
  • A recovery fee is demanded before funds are released
Airdrops

Airdrop phishing forks

A fake airdrop imitates a real brand, copied design system, or trending project and turns curiosity into a signing trap.

  • Domain misspellings or new domains
  • No announcement from official project channels
  • The claim transaction requests unexpected permissions
