You've been told your name or address matches a sanctioned individual on ChangeNOW. ChangeNOW is a non-custodial swap service based in Cayman Islands, regulated under Cayman Islands AML Regulations 2020. Unlike traditional exchanges, ChangeNOW can hold your funds during AML checks even though you never created an account. The service uses AML Bot + Crystal Blockchain for transaction screening. ChangeNOW holds swaps when their AML Bot flags source addresses, requiring KYC before releasing the funds — with no account creation option. You receive a notice that your account has been flagged for a sanctions screening match, or your account is suddenly frozen without explanation. The platform is legally obligated to block accounts with potential sanctions matches pending verification.
ChangeNOW holds swaps when their AML Bot flags source addresses, requiring KYC before releasing the funds — with no account creation option. ChangeNOW uses a dual-screening system: AML Bot for pre-screening and Crystal Blockchain for deeper analysis. This means even low-risk flags can trigger a hold, because the two systems have different sensitivity levels and either one can block a swap. This background matters because it shapes how ChangeNOW handles compliance — and how we approach resolving your case.
The compliance framework: ChangeNOW operates under Cayman Islands AML Regulations 2020, overseen by Cayman Islands Monetary Authority (CIMA). Their compliance infrastructure uses AML Bot + Crystal Blockchain for blockchain analytics and internal for identity verification. ChangeNOW is known for custody-free swaps with no maximum limits, serving privacy-conscious users wanting instant swaps — and their compliance team is calibrated to flag deviations from typical user behavior in that segment.
What triggers sanctions screening on ChangeNOW:
Real case — dual-screening system: A user swapped 2 ETH to BTC on ChangeNOW. AML Bot passed the transaction, but Crystal Blockchain flagged it as 'medium risk' because the source ETH address had interacted with a DeFi protocol that was later associated with a hack. ChangeNOW held the swap output and demanded KYC. The user had never created an account and had no support history. We documented the DeFi interaction as legitimate (the protocol was not hacked at the time of interaction) and ChangeNOW released the funds in 14 days.
What ChangeNOW requires to resolve this: Depending on the trigger, ChangeNOW may ask for government-issued photo ID (verified through internal), proof of address (utility bill or bank statement within 3 months), AML compliance review (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: ChangeNOW rarely tells you which specific trigger caused the sanctions screening, so you're guessing at what documentation to provide — and each rejected submission makes the next one harder.
Our approach is specific to ChangeNOW: ChangeNOW's dual-screening creates ambiguity about which system flagged the transaction. We request the specific risk assessment from both AML Bot and Crystal Blockchain, identify the flagging source, and prepare a rebuttal targeted at that specific system's methodology. Crystal Blockchain's risk scoring is more opaque than Chainalysis, which requires more detailed on-chain evidence.
Sanctions Screening on ChangeNOW — our strategy: We prepare a formal non-association declaration with evidence that you are not the sanctioned individual — different date of birth, different nationality, different address, different occupation — and submit it through the platform's compliance channels with a legal cover letter.
The submission that matters: Instead of submitting through ChangeNOW'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 Cayman Islands Monetary Authority (CIMA) obligations and Cayman Islands AML Regulations 2020. ChangeNOW'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.
Further reading: our guide on OFAC sanctions false positives in crypto covers the documentation and legal strategy in more depth.
We confirm the sanctions match is a false positive by comparing your identity details against the sanctioned individual's known attributes: date of birth, nationality, address, occupation. Partial name matches are the most common cause.
We prepare a formal non-association declaration with evidence: your passport/ID, date of birth, nationality, address, occupation, and a sworn statement that you are not the sanctioned individual. We cross-reference OFAC SDN, EU consolidated, and UN sanctions lists.
We submit the non-association declaration to {p_name}'s sanctions compliance team — not standard support. Our legal cover letter references {regulator} sanctions screening requirements and the false positive rate for common names.
Sanctions screening false positive resolved — account fully restored. We advise on name variations that may trigger future sanctions matches on {p_name}.
ChangeNOW uses two screening systems: AML Bot (pre-screening) and Crystal Blockchain (deeper analysis). AML Bot may pass your transaction, but Crystal Blockchain can still flag it based on different risk criteria. Crystal Blockchain's methodology is less transparent than Chainalysis — they don't publicly disclose their risk scoring parameters. We request the specific risk assessment and prepare a targeted rebuttal.
Yes, under Cayman Islands AML regulations. Even non-custodial services must perform AML checks on flagged transactions. ChangeNOW's position is that holding funds for AML verification is not 'custody' — it's a compliance obligation. While this interpretation is debatable, the practical reality is that your funds are held and you need to provide documentation to get them released.
Platforms screen all users against OFAC SDN, EU consolidated, UN, and national sanctions lists using name-matching algorithms. If your name is similar to a sanctioned individual — even a partial match — your account is automatically flagged. False positives are extremely common, especially for names from the Middle East, Eastern Europe, Africa, and Asia. The flag doesn't mean you're sanctioned — it means the platform needs to verify you're not the sanctioned person.
Platforms screen against: OFAC SDN List (US), EU Consolidated Financial Sanctions List, UN Security Council Consolidated List, UK HM Treasury Sanctions List, and potentially national lists for the platform's jurisdiction. Each list covers different individuals and entities, and a match on any one list triggers a block.
We prepare a non-association declaration that includes: your full legal name, date of birth, nationality, passport number, current address, and occupation — compared side by side with the sanctioned individual's known details from the sanctions list entry. Key differentiators: date of birth (most definitive), nationality, place of residence, and occupation. The more differences we can demonstrate, the faster the flag is cleared.
