Decentralized Finance (DeFi): Unlocking interoperability for digital assets

Euroclear, together with DTCC and Clearstream, in collaboration with Boston Consulting Group, releases the whitepaper, Building the Path Towards Digital Asset Securities Interoperability. The paper identifies the current challenges of achieving interoperability within the decentralized finance (DeFi) ecosystem.

It also explores the different objects of interoperability across the value chain, and proposes a path forward for the industry to collaborate on data standardization, process harmonisation and roles consistency.

According to the report, interoperability will be critical for the DLT markets to be successfully scaled in the coming years. Without homogeneous treatment of assets across different infrastructures, the market may face significant challenges in adopting DLT rails at scale, potentially constraining global interoperability.

„Our perspective is pragmatic – traditional infrastructures and DLT will likely coexist for years, market participants expect continuity, inclusivity, and uncompromised security as they connect. Ultimately, we believe that industry collaboration remains the most effective way to build the ecosystem.” – said the authors of the report.

Key takeaways
1. Interoperability is a prerequisite for DAS adoption at scale.
The current interoperability limitations already create tangible frictions: operational costs are high, liquidity is fragmented, and both operational and regulatory risks remain while volume increases. Without overcoming these barriers, the expected benefits of digital asset securities will be difficult to achieve. Interoperability can enable the seamless execution of foundational use cases, facilitate the scaling of complex ones, and unlock entirely new opportunities. By ensuring the mobility, liquidity, security, and fungibility of assets, interoperability lays the foundation for widespread DAS adoption.

2. Interoperability extends beyond cross-DLT data integration.
Interoperability is built on 5 enduring capital market foundations: assets and liabilities, ownership, asset lifecycle and movement protocols, ledgers, and legal and regulatory compliance. These foundations have remained relevant for decades, and interoperability across all of them is essential to enable asset exchange across DLT or between DLT and traditional ledgers.

3. Interoperability requires industry-wide effort.
FMIs, regulators, market participants, and technology providers should build infrastructure and create standards around data harmonization, process integration, and harmonization of roles and critical functions. The framework described in this paper serves as a neutral reference point to convene this harmonization – helping establish a common taxonomy, anchor outcomes, classify initiatives, and highlight both coverage and gaps.

4. Interoperability should be advanced through a value-led approach.
Defining a market-level phased approach, with each phase focusing on a set of high-value use cases, enables actors to focus on the most critical interoperability areas and address the most important frictions. Each phase should be anchored in measurable outcomes and tested across multiple DLT and traditional finance ledgers. This prioritization leads the way to full scale interoperability over time.

5. Collective action today will shape resilient markets tomorrow.
In traditional finance, it took decades of effort and crisis management to harmonize market processes, data standards and integration approaches. To accelerate and reduce costs, market participants, technology vendors, regulators, and FMIs should come together to identify the salient priorities.

“Interoperability will be essential for DLT markets to scale successfully in the coming years. To deliver meaningful results for clients, the industry must ensure assets are treated consistently across infrastructures while enhancing the liquidity of digital assets and enabling open access to all market infrastructures. Through shared collaboration and deep market expertise, we can provide the intelligence and practical solutions needed to unlock real value, accelerate adoption of DLT rails, and support seamless, global participation at scale.” – said Isabelle Delorme, Head of Product Strategy and Innovation, Euroclear group.
