Elementus

Elementus is a New York blockchain intelligence company founded in 2017 that attributes on-chain addresses to real-world entities across multiple chains, and sells that attribution graph to compliance, investigations and market-intelligence teams. Its public API surface is the Attribution API, a key-authenticated REST service at attribution-api.elementus.io that resolves batches of blockchain addresses to a beneficial owner, custodian, entity name and OFAC/SDN sanction status. As of the 2026-08-12 probe every Elementus web host — the marketing site, the app and the API — is unresolvable in DNS, so the developer surface documented here is reconstructed from the company's own public GitHub organization rather than from a live site.

Elementus publishes 1 API on the APIs.io network. Tagged areas include Company, Blockchain, Cryptocurrency, Analytics, and Compliance.

  detail: Elementus' entire web surface has been withdrawn from DNS — the apex publishes no address record, www.elementus.io
    is NXDOMAIN, and both attribution-api.elementus.io and app.elementus.io are dangling CNAMEs to an AWS load balancer and
    a CloudFront distribution that no longer exist — while the zone itself stays live on Cloudflare and still routes mail
    to Google Workspace, so the company has parked its public presence rather than released the domain.
