How to verify a crypto wallet address before sending

Crypto is irreversible. 5 checks that take 60 seconds and could save your entire balance.

The 5-step verification checklist

  1. 1

    Check the address against scam blacklists

    Paste it into the GACS wallet checker. We cross-reference 50,000+ flagged wallets from CryptoScamDB, Chainabuse, community reports, and known drainer signatures.

  2. 2

    Verify against sanctions lists

    OFAC, UN, EU sanctions lists include thousands of wallet addresses. Sending to one is a federal offense in most jurisdictions, regardless of intent. The wallet checker flags these automatically.

  3. 3

    Check wallet age and activity

    Brand-new addresses with no history are suspicious for legitimate business use. Use a block explorer (etherscan.io, blockchair.com) to verify the address has the activity pattern you'd expect.

  4. 4

    Look for mixer or drainer exposure

    If the address received funds from Tornado Cash, ChipMixer, or known drainer contracts in the recent past, treat it as compromised. The wallet checker shows this lineage.

  5. 5

    Defend against address poisoning

    Scammers send 0-value transactions from addresses that match the first and last 4 characters of one you've sent to before, hoping you'll copy-paste from history. ALWAYS verify the FULL address character-by-character, not just the start and end.

FAQ

Can a wallet address itself be a scam?

The address is just a destination. But it can be: a known drainer/scam wallet, a sanctioned entity, a mixer output, or a poisoning lookalike. All five matter — verify before sending.

What is address poisoning?

Attacker sends a tiny transaction from an address that visually mimics one in your history (same first/last 4 chars). When you next send, you copy from history and miss the difference. ALWAYS check the full string.

How can I verify a Bitcoin address vs Ethereum address?

Same principles, different format. Bitcoin addresses start with 1, 3, or bc1. Ethereum is 0x + 40 hex chars. Solana is base58, ~44 chars. The wallet checker handles all major chains.

Is checking a wallet address public?

On GACS: anonymous, no signup, no logged history. The address itself is already public on the blockchain — checking it leaks nothing about you.

What if the wallet shows clean but I'm still unsure?

Send a tiny test transaction first ($1-2 equivalent), confirm receipt with the counterparty via a separately-verified channel (not the chat that gave you the address), then send the full amount.

Check any wallet in 5 seconds.

Free, anonymous, all major chains.
