CEX.IO subjected you
to EDD? We handle it.

CEX.IO freezes accounts under UK Money Laundering Regulations when their compliance team detects sanctions matches, high-risk deposits, or unusual withdrawal patterns. CEX.IO is one of the few exchanges FCA-registered as a crypto-asset business in the UK. This means they're subject to UK MLR 2017 — one of the strictest AML regimes — but also means they follow due process more rigorously than offshore exchanges. This background matters because it shapes how CEX.IO handles compliance — and how we approach resolving your case.

The compliance framework: CEX.IO operates under UK Money Laundering, Terrorist Financing and Transfer of Funds Regulations 2017, overseen by UK Financial Conduct Authority (FCA). Their compliance infrastructure uses Chainalysis for blockchain analytics and Onfido for identity verification. CEX.IO is known for fiat onboarding and card purchases for beginners, serving entry-level crypto users in Europe and UK — and their compliance team is calibrated to flag deviations from typical user behavior in that segment.

What triggers enhanced due diligence on CEX.IO:

• High-value account: Accounts with balances above CEX.IO's EDD threshold (typically €50,000-€100,000) automatically enter Enhanced Due Diligence under UK Money Laundering, Terrorist Financing and Transfer of Funds Regulations 2017.
• Complex transaction patterns: Chainalysis flags accounts with patterns suggesting layering, structuring, or rapid movement of funds — these trigger EDD even if the funds are legitimate.
• High-risk jurisdiction exposure: If you've received transfers from addresses associated with high-risk jurisdictions (per FATF lists), CEX.IO must conduct EDD to comply with UK Financial Conduct Authority (FCA) requirements.
• PEP or prominent person: Politically Exposed Persons (PEPs) and their family members are subject to EDD on CEX.IO — even if their activity is entirely legitimate.

Real case — FCA regulation: A UK-based user had €30,000 frozen on CEX.IO after making a large withdrawal to a new bank account. CEX.IO's compliance team requested source of funds documentation but the user's funds originated from crypto mining 5 years ago — he no longer had the mining records. We reconstructed the mining history from blockchain evidence (pool payouts, hardware purchase receipts) and CEX.IO released the funds within 8 days.

What CEX.IO requires to resolve this: Depending on the trigger, CEX.IO may ask for government-issued photo ID (verified through Onfido), proof of address (utility bill or bank statement within 3 months), source-of-funds documentation (exchange statements, bank records, payslips, tax returns, or business documents), detailed transaction explanations with on-chain evidence, and in some cases a video verification interview. The challenge: CEX.IO rarely tells you which specific trigger caused the enhanced due diligence, so you're guessing at what documentation to provide — and each rejected submission makes the next one harder.

Our approach is specific to CEX.IO: CEX.IO's FCA registration means they follow UK regulatory procedures — including the right to appeal compliance decisions. We use the FCA's complaints framework to escalate unreasonable freezes. CEX.IO is more responsive to legal pressure than offshore exchanges because their FCA registration is commercially critical and they can't afford regulatory complaints.

Enhanced Due Diligence on CEX.IO — our strategy: We prepare a comprehensive EDD package that addresses every aspect of the platform's request: wealth source documentation, business context, transaction explanations, and a structured legal submission that demonstrates full regulatory compliance.

The submission that matters: Instead of submitting through CEX.IO's standard support channels (where you'll get automated responses or generic template replies), we prepare a professional legal submission — a structured compliance package with a cover letter from a Swiss law firm citing UK Financial Conduct Authority (FCA) obligations and UK Money Laundering, Terrorist Financing and Transfer of Funds Regulations 2017. CEX.IO's compliance team processes legal submissions differently from regular user tickets — they're assigned to senior compliance officers, not support agents, and they bypass the automated response loop that delays most cases by weeks.

When standard compliance isn't enough: Some situations fall outside the normal compliance flow — inherited crypto holdings, accounts registered under another person's name, unprovable source of funds through conventional documentation, or cross-jurisdictional complications where your residence, the exchange's jurisdiction, and the fiat banking path all differ. If that sounds like your case, our complex cases practice handles scenarios that other firms decline.
