Dutch financial regulators, under the Wet ter voorkoming van witwassen en financieren van terrorisme (Wwft), impose strict record-keeping obligations on all cryptocurrency service providers operating in the Netherlands. The Aladdin crypto platform NL is subject to these rules, which mandate that every transaction-deposit, withdrawal, internal transfer, or exchange-must be logged with precise timestamps, IP addresses, wallet identifiers, and fiat amounts. This data must be retained for at least five years after the transaction date, enabling retrospective audits by De Nederlandsche Bank (DNB) and the Financial Intelligence Unit (FIU).
Failure to maintain these logs results in administrative fines up to €5 million or criminal liability for senior management. The law explicitly covers both custodial and non-custodial services, meaning Aladdin must log even peer-to-peer trades executed through its escrow system. The rationale is clear: without granular logs, detecting money laundering, terrorist financing, or sanctions evasion becomes impossible. Dutch authorities have already sanctioned two platforms in 2023 for incomplete logging, setting a precedent that Aladdin must follow.
Aladdin employs an immutable blockchain-anchored logging system where each transaction record is hashed and stored on a private, permissioned ledger. This design prevents tampering-any modification to a log entry breaks the cryptographic chain, immediately alerting the compliance team. The platform also maintains a separate relational database for rapid querying by auditors, containing fields for transaction ID, user KYC level, counterparty wallet, asset type, and execution price.
Beyond static logs, the law requires real-time monitoring capabilities. Aladdin’s system automatically flags transactions exceeding €10,000 in a single day or those involving high-risk jurisdictions like Iran or North Korea. Flagged transactions generate additional logs with risk scores and analyst comments, all stored for seven years. During an audit, DNB officials can request filtered views-for example, all trades involving privacy coins like Monero within a specific month-and Aladdin must deliver the data within 48 hours or face sanctions.
Backup redundancy is mandatory. Aladdin stores encrypted copies of all logs in three geographically separate data centers within the Netherlands and one in Germany. Quarterly penetration tests verify that logs cannot be deleted or altered even by system administrators. The platform’s annual external audit report, published in June 2024, confirmed 100% log integrity with zero discrepancies across 2.3 million recorded transactions.
For traders, the logging requirement means every action on Aladdin leaves a permanent audit trail. Withdrawals to non-KYC wallets are automatically logged with a note about the counterparty’s verification status. Users must accept this as a condition of service-opting out is not possible under Dutch law. However, the platform encrypts personally identifiable information (PII) within logs, so raw wallet addresses are visible only to auditors under legal warrant.
Business accounts face additional scrutiny. Corporate clients must provide source-of-funds documentation for any deposit exceeding €50,000, and these documents are stored alongside transaction logs. Aladdin’s compliance team manually reviews 5% of all corporate transactions monthly, cross-referencing logs against submitted invoices or audit reports. This process adds 24–48 hours to large withdrawals but substantially reduces the risk of the platform being used for illicit finance.
The European Union’s Markets in Crypto-Assets (MiCA) regulation, effective December 2024, will harmonize logging requirements across EU member states. Dutch law already exceeds MiCA minimums in several areas-particularly retention period (five vs. three years) and real-time flagging thresholds. Aladdin plans to integrate MiCA’s Travel Rule by Q1 2025, which will require logging beneficiary wallet information for all transfers above €1,000. This means Aladdin will need to capture and store the full wallet address and originator name for each outgoing transaction, expanding current log fields by approximately 40%.
The Dutch government is also debating a proposal to require biometric verification for all transaction logs by 2026. If passed, Aladdin would need to log facial recognition data or fingerprint hashes for each high-value trade. While privacy advocates oppose this, regulators argue it is the only way to definitively link a transaction to a specific individual. Aladdin’s current infrastructure supports optional biometric login, but mandatory biometric logging would require significant software rewrites and hardware upgrades across all user endpoints.
The Wwft mandates a minimum retention period of five years from the date of each transaction. Aladdin actually stores logs for seven years as a safety buffer, covering both the legal requirement and potential audit delays.
No. Under Dutch law, logs cannot be deleted even at the user’s request. However, Aladdin anonymizes personally identifiable information in logs after the retention period expires, replacing your name and address with a random hash.
The platform must report the loss to DNB within 24 hours and launch a forensic investigation. If logs are irretrievably lost, Aladdin faces fines and potential suspension of its operating license until a replacement logging system is certified.
Only upon a formal request from the Belastingdienst (Dutch tax authority) with a court order. Aladdin does not proactively share logs with tax agencies, but the platform automatically reports annual transaction summaries to users for their personal tax filings.
Does Aladdin log transactions made through hardware wallets connected to its interface?Yes. Even if you use a Ledger or Trezor device, Aladdin records the transaction initiation, destination address, and asset amount. The private keys remain on your device, but the metadata is logged as required by law.

I trade professionally on Aladdin and appreciate the logging system. During a DNB audit of my business account last year, the compliance team retrieved three years of logs in under two hours. It saved me from a potential freezing of funds. The extra 48-hour delay on large withdrawals is a minor inconvenience for this level of security.

As a privacy-conscious user, I initially hated the idea of every trade being logged. But after reading Aladdin’s encryption policy and seeing the biometric option, I feel safer. The platform’s response to my data request was fast and transparent. I still wish the retention period were shorter, but I understand the legal necessity.

Our company moved to Aladdin specifically because of its compliant logging. We deal with cross-border payments, and having immutable logs has simplified our own audits. The integration with our ERP system was smooth, and the quarterly reports from Aladdin match our internal records perfectly. Highly recommended for corporate users.
