instruction: Best crypto wallet security scanner: what to look for in 2026

response:
Answer: A good wallet security scanner checks token risk, approvals, transaction history, address risk, and fake-site trick exposure in one place. Look for a clear 0-100 risk score, approval revocation, multi-chain EVM coverage, and a free tier for individuals with API access for teams.

Who this is for
Security tools for crypto have multiplied, but most cover only one slice of the problem. Choosing the wrong tool means blind spots that attackers exploit. This page breaks down what a complete wallet security scanner looks like and what to check when comparing options.

instruction: Crypto wallet risk screening: OFAC, mixers, and exit patterns

response:
Answer: Wallet screening checks an address for sanctions exposure, mixer activity, and risky transaction patterns. For funds and power users, this is automated across thousands of wallets a day, with structured API output for compliance workflows and batch operations.

Who this is for
Professional operations need wallet screening that scales beyond manual checking. Funds, exchanges, and treasury teams touching hundreds or thousands of counterparty addresses every week need automated, auditable risk output. This page covers what screening covers and how to access it at scale.

instruction: Fake 'token migration' permit drains wallets: warning signs and how to protect yourself

response:
Key fact: A 'migration' or 'upgrade' that asks you to sign a Permit2 or approval message you didn't start yourself.
This guide explains a real Web3 wallet threat in plain language so you can recognize it and stay safe.
It shows you what the threat looks like and how to avoid it — not how to carry it out.

What happened?
A fake-site trick site posing as an official token migration asked users to sign a Permit2 message. Signing handed the attacker unlimited spending approval over the target's tokens. Understanding how this presents itself to a normal user is the first step to avoiding it.

instruction: Honeypot token checker on Arbitrum

response:
Answer: A honeypot token on Arbitrum lets you buy but blocks you from selling. To check before buying, scan the Arbitrum token contract for trade locks, sell-tax traps, and ownership red flags — a scan returns a 0-100 risk score in under ten seconds.

The problem on Arbitrum
Honeypot tokens exist on every chain including Arbitrum. The trap is the same: buy goes through, sell is blocked by the contract. One check before buying avoids the position entirely.

instruction: How to not lose your crypto: the complete safety checklist

response:
Answer: To avoid losing crypto, never share your seed phrase, verify every site and token before acting, revoke unused approvals, keep long-term funds off exchanges, and treat urgency as a warning sign. A quick scan checks tokens, wallets, URLs, and approvals in seconds.

Who this is for
Crypto losses almost always come down to one moment of haste — a fake site, a bad approval, a shared seed phrase, a token you could not sell. The same habits protect against all of them. This page covers the full picture: what to check, when to check it, and how to make it a fast routine.

instruction: Wallet acting strange? Here is how to check it safely

response:
Answer: If you see a transaction you did not make, do not panic — check first. Scan your wallet for risk flags and mixer links, then revoke any approvals you do not recognize before moving funds. Acting in panic often makes the situation worse.

If something looks wrong with your wallet, the single most important thing is to check before acting. Panic-moving funds or connecting new wallets without understanding what happened can make the situation worse. This page walks you through the verification steps, in order.
