How Arbitrum phishing works
Phishing against Arbitrum follows patterns common to crypto exchanges & wallets. Typical lures:
- A "withdrawal request" or "unusual login" alert pushing you to a fake exchange login.
- A "wallet validation" or "sync your wallet" page that asks for your seed phrase.
- A fake airdrop, mint or support-desk message sent through Discord, X or Telegram.
- A spoofed firmware or app update that replaces your wallet software.
Red flags
- Any site that asks for your recovery or seed phrase is stealing it, with no exceptions.
- Support staff who message you first on social media or chat are impersonators.
- The wallet or exchange link arrived through an ad, DM or email rather than a bookmark you made yourself.
Real Arbitrum domains
If the address in your browser is not one of these (or a subdomain of them), it is not Arbitrum. The list is not exhaustive.
arbitrum.ioIf you already clicked or entered details
Move any remaining funds to a new wallet created on a clean device, revoke token approvals, change exchange passwords and 2FA, and contact the platform through its official site. Transfers on a blockchain cannot be reversed, so speed matters.
Protecting a brand like Arbitrum from lookalike domains
If you run security, brand or fraud for a company that is copied this way, this is the order that works in practice:
- Enforce DMARC. Move your policy to quarantine, then reject, so attackers cannot send mail that passes as your domain.
- Watch new registrations. Lookalikes appear daily; the earlier you see one, the sooner you can act, ideally before the first email goes out.
- Register the obvious typos and keyword variants you can afford to hold, and check which lookalikes are already registered by someone else.
- Report fast. A live fake needs a request to the registrar and host, plus a report to browser safe-browsing lists and the public feeds shown above.
- Tell your customers where you will and will not ask for logins, codes or payments.
Protect your brand from lookalike domains
Arbitrum is one of 2108 brands in this index, but attackers copy any company whose customers log in or pay. PhishPin checks your domain for registered lookalikes, email-spoofing gaps and listings in these same phishing feeds, then helps you get the fakes taken down.
Audits use public data only – we never touch your servers. Results within 24 hours.
Questions about Arbitrum phishing
How can I tell if a message from Arbitrum is phishing?
Check the sender and link domain first. Any site that asks for your recovery or seed phrase is stealing it, with no exceptions. Support staff who message you first on social media or chat are impersonators. The wallet or exchange link arrived through an ad, DM or email rather than a bookmark you made yourself. When in doubt, do not use the link: type arbitrum.io into your browser or open the official app.
How many Arbitrum phishing sites has PhishPin found?
As of 7 Nov 2026, 50 hostnames referencing Arbitrum appear in the phishing feeds PhishPin indexes (50 reported URLs). These are reported hostnames, not a count of sites that are online today; many are removed quickly and some matches are coincidental.
What do fake Arbitrum domains look like?
In our data, the most common ending for reported hosts is .app. The brand is most often combined with the word "portal". 22 hosts put the brand name in a subdomain of an unrelated site. Always read the part of the address just before the first single slash: that is the real site. Real Arbitrum addresses end in arbitrum.io.
What should I do if I entered my details on a fake Arbitrum page?
Move any remaining funds to a new wallet created on a clean device, revoke token approvals, change exchange passwords and 2FA, and contact the platform through its official site. Transfers on a blockchain cannot be reversed, so speed matters.
How do I report a fake Arbitrum website or message?
Forward phishing emails to reportphishing@apwg.org, report scams at reportfraud.ftc.gov, and report the page to Google Safe Browsing. Also tell Arbitrum through the contact options on its official website (arbitrum.io).
Is it safe to visit the domains listed on this page?
No. They are shown defanged, with dots in brackets, so they cannot be clicked by accident. Do not type them into a browser. Listings are warnings from automated matching, and some are harmless coincidences. Treat everything listed as potentially phishing, infected or malware, and have a certified security expert review any list before you block, import or act on it. PhishPin is not responsible for loss or damage from using this data.
How does PhishPin find lookalike domains of Arbitrum?
We read the daily list of newly registered domains (1,050,000 domains over the last 15 days) and flag those that contain the brand name, differ by one character or swap look-alike characters. A match is a warning sign, not proof of abuse.
How can a company protect its own brand from lookalike domains like these?
Publish an enforced DMARC policy so nobody can send mail as your domain, monitor newly registered domains that resemble your name, register the obvious typo domains, and file takedown requests with the registrar, host and browser safe-browsing lists when a fake goes live. PhishPin's free brand audit checks the first three for your domain.
