Luxembourg Blockchain Law IV
Luxembourg's Blockchain Law IV is the Law of 20 December 2024 amending the country's framework for dematerialised securities and the financial sector. It is the fourth major Luxembourg legislative measure intended to support the use of distributed ledger technology in capital markets.

- What it is
- What does Blockchain Law IV do?
- Key things to know
The law builds on Luxembourg's earlier blockchain legislation by expanding the ways in which dematerialised securities can be issued and held using DLT. Its central innovation is the introduction of a new regulated role—the control agent—which can maintain the issuance account and oversee the integrity of an issuance without requiring the traditional structure to operate in exactly the same way as before.
The aim is not to create a separate category of "crypto securities." Rather, it provides additional legal infrastructure for issuing conventional financial instruments digitally while preserving legal certainty, investor protection and regulatory accountability.
What does Blockchain Law IV do?
Introduces the Control Agent
Creates a new regulated function for a control agent responsible for maintaining the issuance account, monitoring the chain of holdings and reconciling the number of securities issued with the securities recorded across the relevant accounts.
Enables a New DLT Issuance Model
Allows dematerialised securities to be issued through a structure in which the control agent manages the issuance record while account keepers maintain securities accounts within the distributed ledger.
Expands Issuance Flexibility
Provides issuers with an alternative to the existing central account keeper model, allowing them to use DLT-based infrastructure without abandoning the legal framework applicable to dematerialised securities.
Preserves the Existing Legal Character of Securities
A security issued or recorded using DLT remains a financial instrument subject to the normal rules governing securities, including applicable issuance, custody, distribution and investor-protection requirements.
Creates a Regulated Point of Accountability
Although the infrastructure may be distributed, the law retains an identifiable regulated actor responsible for the accuracy and integrity of the issuance account and reconciliation process.
Strengthens Luxembourg's Digital Capital-Markets Framework
Builds on Luxembourg's earlier blockchain laws and complements EU initiatives such as the DLT Pilot Regime by providing domestic legal certainty for DLT-based issuance and holding structures.
Key things to know
The law is about tokenised securities, not crypto-assets generally
Blockchain Law IV concerns dematerialised securities and capital-markets infrastructure. It does not replace MiCAR or create a general licensing regime for cryptoasset services.
The control agent is an alternative, not a complete removal of intermediaries
The law modernises the traditional issuance model but does not eliminate regulated functions. It introduces a new accountable actor whose role is adapted to distributed infrastructure.
DLT does not change the regulatory classification
A tokenised share, bond or fund interest remains subject to the legal framework applicable to that financial instrument. Firms still need to consider MiFID II, prospectus, market-abuse, custody, fund and settlement rules where relevant.
The issuance record and investor accounts perform different functions
The control agent maintains the issuance account and reconciles the total issue, while securities may be held through account keepers on accounts maintained within the DLT environment. The roles and responsibilities of each participant must therefore be clearly designed and documented.
Legal certainty depends on the wider operating model
Issuers still need to address governance, access rights, private-key management, ledger permissions, reconciliation, cybersecurity, business continuity and correction of errors. The legislation enables the model but does not solve every implementation risk.
Luxembourg now offers several DLT routes
The appropriate structure may depend on whether the project involves domestic dematerialised securities, tokenised fund interests, market infrastructure under the EU DLT Pilot Regime or crypto-assets under MiCAR. Firms should determine which framework applies before selecting the technology or issuance architecture.
