Real-time scam intelligencefor crypto

Harbor describes a blocklist of phishing sites, drainer pages, and scam addresses. A free browser add-on for one person. An API when a team needs the same list.

Networks the blocklist is built to watch

  • Ethereum
  • Bitcoin
  • Solana
  • Tron
  • TON
  • Sui

How the data is made

One pipeline, from a sighting to the list

The add-on and the API are meant to read one feed. Candidates come in, get checked, then land on the list. The counts below are samples for this page.

01 · Detect

31M URLs scanned

Candidate sites and addresses are gathered around the clock from separate sources.

02 · Verify

412K scams identified

An entry is checked before it is listed. A machine first, a person when the call is unclear.

03 · Deliver

186K domains blocked

Checked rows would ship to the API and the add-on from that same list.

For teams

Look up a domain or an address

One lookup, answered near the edge. The snippet below shows the shape of a response. This page does not call a live API.

  • Domain and URL checks, one at a time or in a batch
  • Address checks, one at a time or in a batch
  • A list export for teams that screen on their own

Example site check

$ curl "https://api.example/v1/site?url=https://swap-portal-fi.net" \
  -H "authorization: Bearer $SAMPLE_KEY"

{
  "host": "swap-portal-fi.net",
  "status": "BLOCKED"
}

Sample response. This page does not send that request.

Type a sample host from the feed. This demo does not call a live API.

Wallets and add-ons

Check a link against the domain list before someone opens it.

Security desks

Fold the list into the alerts and tracing you already run.

Risk and compliance

Screen an address against known scam addresses during a review.

Field notes

Notes from the same pipeline

Short notes for people who sign on a phone, and for the desks that watch those flows.

Abstract dark panel with a phone outline and a small red mark

Where phone phishing tends to start

A lot of the losses traced in this story begin on a phone, inside an ad or a popup, not from a desktop bookmark.

A lookalike name is often up for hours, not weeks. A list only helps if it moves on that clock.

Abstract dark panel with a pointer and a warning bar

From an ad click to a seed request

The page after a bad ad often does not ask for a signature first. It asks for a recovery phrase, dressed up as a restore.

This page will not ask you for a seed phrase. A blocklist does not need one.

Abstract dark panel with a signature line and a red mark

When the preview before you sign is wrong

A preview can show a friendly balance change while the transaction underneath does something else.

The add-on in this story is meant to flag that kind of prompt before an approval leaves the phone.

Do not paste a seed phrase, private key, or recovery words into any field. This page does not ask for them.
