The Depository Trust & Clearing Corporation (DTCC) processes nearly $4 quadrillion in securities annually. To modernize this vast infrastructure, DTCC has filed a patent titled “Systems, Methods, and Storage Media for Managing Digital Liquidity Tokens in a Distributed Ledger Platform” (US20250078162A1). This patent outlines a framework for tokenizing liquidity across various asset classes, integrating digital assets like XRP and XLM. It complements the previously discovered DTCC patent focusing on hierarchical rights delegation.
Tokenizing Liquidity: A New Class of Market Infrastructure
The core concept introduced in this DTCC patent is the liquidity token, which represents ownership in a market-making function between two assets. Instead of relying on centralized market makers or arbitrage strategies, the patent proposes a programmable liquidity mechanism managed entirely on-chain. These tokens can generate value through trading activity and price movements that reflect the demand for liquidity rather than just supply.
Each liquidity token includes:
- A unique token identifier,
- Wrapping logic for converting non-fungible tokens (NFTs) into fungible, divisible instruments,
- Integration with valuation functions and compliance policies,
- Ownership of the assets involved in market-making.
This structure enables a system where capital flows toward asset pairs experiencing higher liquidity demand. Tokens incentivize participation by rewarding holders with revenue tied to network usage. The architecture supports fractional ownership and recursive asset nesting, creating flexible fund structures akin to ETFs and structured credit pools.
XRP and XLM: Interoperability Anchors in the Design
Role of XRP and XLM in the Patent
The patent explicitly lists XRP and XLM as compatible networks within its cross-ledger liquidity framework. These assets aren’t just mentioned—they’re structurally supported within the system’s modular bridge architecture.
Both XRP and XLM serve key functions in enabling low-cost, high-speed asset movement across networks:
- XRP (XRP Ledger):
- Supports ~1,500 TPS with near-instant finality.
- Optimized for institutional cross-border settlement.
- Can be wrapped inside liquidity tokens for programmable fund management.
- XLM (Stellar Network):
- Enables ultra-low fees and fast transactions.
- Designed for fiat on/off ramps and global remittance use cases.
- Well-suited for pairing with stablecoins and wrapped securities.
The patent includes metadata models for bridge nodes, allowing assets like XRP and XLM to flow between chains. These nodes define wallet formats, supported tokens, and routing logic for transactions across distributed ledgers.
While Ethereum remains the base layer for issuing tokens, XRP and XLM play essential roles in:
- Reducing transaction costs for liquidity operations.
- Supporting cross-chain fund entry and redemption.
- Enabling interoperability across regulated and public blockchain networks.
Their inclusion reflects the patent’s goal: building a compliant, multi-network asset framework that operates efficiently across platforms with different strengths.
Architecture of the System: Modular Design and Interoperability
At the foundation is a multi-module system including:
- Asset Registry: Issues non-fungible tokens for assets, assigning classes and wallet addresses.
- Wallet Contracts: Enable each token to own other tokens or assets, enabling nesting.
- Valuation Modules: Provide real-time asset pricing using market data, oracle feeds, or internal logic.
- Liquidity Reservoir: A smart contract buffer adjusting price based on capital inflow or redemption, ensuring elastic fund growth or contraction.
Cross-network transactions use a graph of bridge nodes representing entry and exit points on supported blockchains. Each node stores metadata, including supported tokens, APIs, wallet logic, and pricing models. The system plans and executes multi-step asset transformations by selecting optimal paths through this graph. Transfers are executed using Zero Knowledge Proofs and an ontology layer that converts generic instructions into chain-specific formats.
The result is a programmable, compliant infrastructure for liquidity provisioning that scales across networks and jurisdictions.
Compliance and Valuation Frameworks
Transparency and regulatory alignment are critical for institutional adoption. The patent builds upon earlier DTCC-aligned disclosures like US20190164151A1, extending them with compliance-aware token logic. Each asset includes:
- Smart contract-based valuation standards (e.g., NAV, PAR, Market Value),
- Attribute attestations from verification agents,
- Policy engine enforcement (e.g., who can access, transfer, or audit an asset).
For example, a self-processing loan token within a fund can autonomously update its PAR value based on repayments. If the loan defaults, waterfall logic triggers capital replenishment from reserve pools. These events are transparently recorded on-chain, improving auditability over legacy fund operations.
Wrapping and Nesting: Complex Fund Structures Made Simple
One of the patent’s most impactful elements is its token-in-token model. A liquidity token may hold:
- Shares of other funds,
- Other liquidity tokens,
- Wrapped third-party tokens like XRP or XLM,
- Fiat-backed stablecoins or on-chain debt instruments.
This recursive structure supports advanced use cases, including:
- Securitized loan pools with real-time performance reporting,
- Diversified ETF-like instruments for RWAs,
- Multi-token-backed synthetic assets with internal yield generation.
Through this approach, DTCC creates a unified framework for both asset creation and liquidity management, reducing the gap between TradFi structure and DeFi innovation.
Comparison to DTCC’s Rights Delegation Patent
This digital liquidity token patent complements another DTCC patent—US20250078065A1, previously explored in this article. That filing centers on rights delegation, hierarchical wallet control, and secure identity management using “root” and “delegate” structures. It emphasizes governance, revocation, and compliance within enterprise environments.
Where the liquidity token patent builds the infrastructure for on-chain market making and tokenization, the rights delegation patent ensures institutional control and user accountability. Together, they form a dual-pillar strategy:
- One defines how assets flow and earn value.
- The other governs who controls them and under what rules.
Both patents reference multi-chain ecosystems and share compatibility with XRP, XLM, and Hedera Hashgraph, reflecting a cohesive vision of interoperable finance.
A Foundation for the Next Phase of Digital Markets
The DTCC digital liquidity token patent signals a strategic move toward programmable market infrastructure. It introduces a complete lifecycle for tokenized liquidity, enabling fund managers, asset issuers, and networks like XRP or Stellar to interoperate under transparent, programmable, and compliant conditions.
By nesting assets, automating valuations, and abstracting cross-network logic, the system proposes a realistic blueprint for evolving how value moves between people, institutions, and ledgers. As financial infrastructure evolves, patents like these provide a lens into how traditional firms are positioning themselves—less as intermediaries, more as infrastructure providers—where networks like XRP and XLM may play crucial roles in routing liquidity across a decentralized world.
