Due diligence that actually works — before it's too late.
The secondary OTC crypto market moves billions every week — but it's plagued by broker chains, anonymous chat-room deals, rented wallets, and outright fraud. Sanctum gives serious traders and intermediaries the compliance intelligence they need to screen counterparties and trade with confidence.
Billions of dollars in OTC crypto trades collapse, stall, or end in fraud every year. The same patterns repeat: chains of brokers who've never met the asset holder, deals struck in Telegram groups with no identity checks, and wallets that look funded but are borrowed or controlled by third parties. Legitimate buyers and sellers carry all the risk.
By the time a deal reaches the table, it may have passed through 4–8 intermediary "mandates" — each adding a layer, each untraceable. Nobody can verify who actually holds the asset or speaks with authority for the seller.
Telegram, Signal, and WhatsApp have become the trading floors of the shadow OTC market. Anonymous usernames, unverified screenshots of balances, and zero accountability when it falls apart.
A funded wallet temporarily provided to a buyer as "proof of funds." The balance is real — but the buyer doesn't own it. The moment the deal advances, the wallet is swept clean and the buyer is left empty-handed.
Fake LOIs, BCLs, and seller mandates claiming non-existent inventory circulate continuously through broker networks. Without on-chain verification, there is no deal — only a money and time sink.
Forged passports, invented corporate structures, and AI-generated identity documents are now common in large OTC negotiations. Manual spot-checks no longer provide adequate protection.
Intermediaries who facilitate transactions without adequate due diligence face sanctions risk, AML liability, and in some jurisdictions, criminal exposure — regardless of whether they "knew" or not.
We don't replace lawyers or full AML investigations. What we provide is a clear, structured report on the things that matter most — wallet history, sanctions flags, identity markers, and pattern recognition — so you can make an informed decision before committing to any transaction.
Full transaction history analysis for BTC and TRON wallets: age, funding source, outbound patterns, exchange attribution, and rental wallet flag detection.
Automated cross-reference against OFAC SDN, EU consolidated lists, and major international watchlists. Entities and wallet addresses both checked.
Passport MRZ checksum validation, corporate structure review, and counterparty identity reports prepared for each principal in the deal.
SPAs, Working Tickets, and a numbered DD Registry — all generated from a single deal intake. Consistent, professional, audit-ready.
We don't clear the deal — we clear the fog. Sanctum gives you the facts so you can make the call.
Every report we produce is a timestamped, reference-numbered document that records what was checked, when it was checked, and what was found. If a deal goes sideways, you have documented evidence of your due diligence process — not just a conversation log in a Telegram chat.
Sanctum membership gives you access to the full compliance workflow — built for OTC practitioners, not compliance departments.
Enter the buyer, seller, BTC/USDT amounts, and the wallet addresses to be screened. Takes two minutes.
Wallet addresses are checked on-chain. Entities are run against sanctions lists. Passports are verified against ICAO MRZ checksums.
PDF DD reports are produced with a unique CWDD reference number, recording methodology, findings, risk rating, and recommendations.
Reports can be shared as a condition of proceeding. Clean reports build trust; flags create accountability and documented conditions.
Every report is registered in your deal registry with a CWDD number. Fully auditable if you ever need to demonstrate your compliance process.
Membership is by application only. All applicants are reviewed before access is granted.
