Why do banks ask questions

First and foremost, the bank does this for its own security reasons. It must prove to the regulator that its client is not involved in illegal operations and that the bank's representatives are not part of potential criminal schemes.

Today, even large official companies face transaction delays due to bureaucratic peculiarities of AML or if documents are incomplete or unclear.

FAQ: How to Successfully Pass AML and KYC Verification for Crypto Assets

What is KYC and AML and what do they mean in financial services?

KYC (Know Your Customer) and AML (Anti-Money Laundering) are two interconnected compliance frameworks that regulated financial institutions are legally required to implement. KYC is the process of verifying who a client is — confirming their identity through official documents before any financial relationship begins. AML is the broader system of controls designed to detect, prevent, and report transactions that may be connected to money laundering, fraud, or other financial crimes. Together, KYC and AML form the foundation of compliant financial operations in the EU and globally.
KYC focuses on the client: who they are, where they live, and whether their identity is verifiable. AML focuses on the money: where it came from, how it moved, and whether any transaction patterns suggest illegal activity. KYC is typically a one-time onboarding process, while AML is an ongoing monitoring function applied to every transaction. At Xpaid, both are integrated into a single seamless process — clients are verified once, and every subsequent transaction is AML-screened automatically.
The Xpaid compliance process runs in two stages. First, KYC verification: the client submits a valid government-issued ID and a proof of address document (issued within the last 3 months), which are reviewed within 1–2 business days. Second, AML screening: once the client provides their crypto wallet address, Xpaid conducts a full blockchain AML scan of the funds using industry-standard analytics tools. Only after both stages are successfully cleared does the transaction proceed to the conversion and transfer stage.
Crypto-specific KYC/AML verification adds a blockchain analytics layer to the standard compliance process. Beyond verifying the client's identity, Xpaid screens the wallet addresses involved in the transaction for risk factors: connections to mixers, darknet-linked addresses, sanctioned entities, or structuring patterns. EU banks require this level of AML clearance before accepting any crypto-originated transfer. Xpaid's screening is conducted using certified blockchain analytics platforms — ensuring that the AML report accompanying the transaction is recognised and accepted by receiving banks.
Standard KYC documentation includes a valid passport or government-issued identity document, and a proof of address (such as a utility bill or bank statement, no older than 3 months). For certain transaction types or amounts, additional Source of Wealth documentation may be required. Your Xpaid manager will specify the exact document requirements before you begin, so there are no surprises mid-process.
No. KYC verification is completed once during initial onboarding and remains valid for ongoing transactions. AML screening is applied per transaction — specifically to the wallet addresses and amounts involved in each deal — but this is handled entirely by Xpaid and requires no additional action from the client. Re-verification may be required only if there is a significant change in client data or after an extended period of inactivity.
If the AML scan identifies risk factors associated with a wallet address — such as links to high-risk counterparties or flagged transaction patterns — Xpaid cannot proceed with the transaction. In this case, the client is informed of the screening outcome transparently. Depending on the specific findings, a resolution may be possible through additional documentation or by using a different wallet with a clean transaction history. Xpaid does not proceed with transactions that present unresolvable AML risks — this protects both the client and the receiving bank.
Yes.
