Overview
Trading, custody, and settlement are the 3 functions that determine whether a capital market works at all: whether a trade executes reliably, whether the underlying asset is safely held, and whether ownership transfers with finality once the transaction is reported to regulators. Building that infrastructure on a blockchain does not lower the regulatory bar; it holds the same one. What the blockchain adds is a shared, auditable settlement layer that multiple regulated parties can rely on simultaneously.
Why Regulatory Pilot Regimes Exist
Regulators in major markets have created structured pathways, such as the EU's DLT Pilot Regime, to let firms test blockchain-based securities infrastructure under real market conditions rather than forcing them into rules written for paper-based and centralized electronic systems. These regimes require a firm to demonstrate that trades can be reported, settled, and reversed only through defined regulatory procedures, that custody meets the same standards as centralized systems, and that the infrastructure operates at the reliability level regulators expect of critical market infrastructure. Clearing that bar is a multi-year regulatory process rather than a technical afterthought.
What a Compliant Trading and Settlement Stack Requires
For a blockchain-based trading and settlement system to satisfy regulators, transaction finality has to be deterministic. If a consensus mechanism permits reorganization, a settled trade could be unwound after being reported to regulators, which is a compliance failure serious enough to void a license outright. The network also has to support compliance logic, participant permissions, and data visibility rules configured at the infrastructure level rather than solely within an individual application, so that custody and reporting obligations are met consistently across every asset issued on the system. The requirement is not performance. It is that the record cannot move once it has been reported.
Trading and Settlement Infrastructure on Avalanche
Spain's CNMV authorized Securitize to operate a blockchain-based Trading and Settlement System under the EU DLT Pilot Regime, running entirely on Avalanche. The authorization makes tokenized stocks, bonds, and fund shares tradable through a single regulated platform across all 27 EU member states. Securitize spent more than 4 years working with the CNMV, ESMA, and the European Central Bank to secure it, and chose Avalanche because sub-second deterministic finality removes the risk of a settled trade being unwound after it has been reported to regulators, a failure mode that would have blocked the license entirely. Securitize's platform also manages more than $5 billion in onchain assets for institutions such as Apollo, VanEck, and KKR, which gives the EU trading system a base of institutional-grade assets from day one.
The same infrastructure supports custody and settlement relationships beyond trading venues. Anchorage Digital Bank serves as bond trustee and qualified custodian for Galaxy Digital's tokenized CLO, with settlement running through the Atlas Settlement Network. Custody, trustee, and settlement functions are each performed by a separate regulated entity on shared infrastructure.
What This Means for Your Company
For a trading venue, custodian, or transfer agent, building on infrastructure that already supports deterministic finality and configurable compliance controls shortens a regulatory and technical path that took Securitize more than 4 years to clear. Custody and settlement guarantees do not have to be built from first principles when the infrastructure has already been vetted by regulators through frameworks such as the EU DLT Pilot Regime, and control over the custody, trustee, and compliance functions a license requires stays with the licensed firm.
Vetted infrastructure is not a license, and a pilot regime is not a permanent one. Each venue still clears its own authorization with its own regulator, and the DLT Pilot Regime remains a testing pathway with defined limits rather than settled market rules. The finality problem is solved at the network layer. Authorization is still granted one firm at a time.
