Who does this wallet transact with? Recent activity (~100 transactions) aggregated into a ranked counterparty list: address, explorer name where known, interactions in/out, total native value, first/last seen, methods used. The related-wallets answer from open data — honest about being a recent-activity sample.

Pre-transaction risk screening for a domain, company or email domain: DNS resolution, MX presence, SSL validity/expiry, domain age via RDAP, website reachability. Returns risk score 0–100, risk level, per-check results and evidence. Run it before an agent pays, emails or integrates with an unknown party.

One call, four public sources: how old the domain is (RDAP), whether mail to the contact will land (DNS), whether the name is on the OFAC list, and whether the company exists in the global LEI register. Returns a single GO / HOLD / STOP with every signal that produced it. Built for the moment an agent has to trust an invoice, a new vendor or a payment-detail change — the classic fraud pattern is a real-looking name on a domain registered weeks ago.

Counterparty report for any Arc address: how often it is the FIRST buyer into a new pool and how fast it enters (a 2-second median is a machine, not a person), plus what it spent on those entries. IMPORTANT LIMIT: our scanner records only a pool's first buyer and only that pool's first 8 swaps, so later sales are NOT observed — treat the money figures as entry spend and early exits, not a full ledger. Behaviour, not identity; absent from our index means unknown, not safe.
