# Glacier21

> Blockchain address and entity intelligence for fraud, compliance, investigations, and litigation teams. Off-chain data, on-chain analytics, and an AI analyst attached to every search across 35+ chains, 200M+ labeled wallets, and 600M off-chain tags.

Glacier21 is a Washington, DC metro area company. We sell three things:

1. A self-serve API (`api.glacier21.com`) for fraud and compliance teams that want sub-100ms wallet intelligence in their stack.
2. A guided integration service that embeds Glacier21 into existing fraud, compliance, KYT, and KYC platforms.
3. A white-glove investigations practice staffed by former federal prosecutors, FBI veterans, and crypto-native engineers, handling asset recovery, sanctions exposure, subpoena response, and expert testimony.

The platform fuses on-chain forensics with off-chain identity data sourced from public records, leaks, OSINT, regulatory filings, and dark-web intelligence. Every API call returns plain-English risk narrative with citation trail, ready for SAR filings and litigation.

Numbers approved for marketing: 35+ blockchains, 200M+ labeled wallets, 600M+ off-chain tags, 200+ sources. The team and roadmap are credible because the founders have previously shipped public-records platforms used by law enforcement and built and sold a web3 platform acquired in 2022.
