KYC and AML… the basics

KYC is Know Your Customer… verifying a user’s identity before offering financial services.
AML is Anti-Money Laundering… rules and monitoring designed to detect and report illicit activity.
Exchanges follow KYC/AML so they can legally operate, connect to banks, and offer fiat ramps.

Why exchanges ask for your data

  • Legal requirements from regulators and banking partners
  • To prevent fraud, stolen card chargebacks, and account takeovers
  • To comply with sanctions and reporting thresholds
  • To enable higher limits, fiat deposits, and card withdrawals

What data they usually collect

  • Full name, date of birth, residential address
  • Government ID… passport or driving licence
  • A live selfie or liveness video
  • Sometimes proof of address… bank or utility statement
  • Source of funds questions for higher tiers

How verification works… step by step

  1. Create an account and start identity verification
  2. Submit ID photos and a quick selfie… liveness checks run in the background
  3. Automated screening against sanctions and PEP lists
  4. If needed, manual review for edge cases
  5. Account tier is granted… higher limits may require more documents

AML monitoring after signup

  • Transaction monitoring… patterns that look like mixing or layering
  • Withdrawals to high-risk services may be flagged
  • Large deposits or fiat movements can trigger enhanced checks
  • Suspicious activity may be reported to authorities

Regional notes… UK, EU, US, UAE

  • UK/EU… strong ID rules, travel-rule messaging between platforms is expanding
  • US… strict fiat on-ramps, tax reporting, state licensing layers
  • UAE… licensed VASPs with clear KYC tiers and source-of-funds checks
    Rules evolve… exchanges update policies as licences and partners change.

Centralised vs decentralised… what changes

  • CEX… KYC/AML almost always required for fiat
  • DEX/self-custody… no KYC at wallet level, but bridges, on-ramps, or off-ramps can still screen flows
  • Using a DEX doesn’t remove tax or legal obligations in your country

Privacy and security… do the basics well

  • Enable app-specific passwords and unique emails
  • Turn on two-factor authentication… avoid SMS where possible
  • Use withdrawal address whitelists and small test sends
  • Keep ID scans off shared clouds… store locally with encryption
  • Review connected devices and API keys quarterly

Your rights… and how to use them

  • You can ask what data is stored… and request corrections
  • You can request deletion when you close an account… legal retention may still apply
  • You can export account history for your records
  • If a platform suffers a breach, you should be notified and advised on next steps

How to minimise data exposure… practical tips

  • Use reputable, licensed exchanges with clear security pages
  • Verify once at a top-tier venue… avoid repeating KYC across many sites
  • Keep limits reasonable… don’t unlock tiers you don’t need
  • Separate trading and long-term holding… self-custody for savings

Common snags… and fixes

  • Verification loop… re-shoot photos in bright, even light
  • Name mismatch… match your ID exactly
  • Proof-of-address rejected… provide a recent bank or utility PDF with full address visible
  • Source-of-funds request… share concise statements and a short explanation

Mini FAQs
