Overview
This proposal introduces a DAML-native contract framework for separating principal and yield rights in tokenized credit instruments on the Canton Network. The objective is to provide regulated financial institutions with programmable tools/sdk to model, transfer, and settle structured credit exposures in a privacy-preserving and synchronized environment.
While public DeFi protocols have introduced principal and yield tokenization in transparent markets, there is currently no equivalent institutional-grade framework that operates within a permissioned, compliance-oriented distributed ledger such as Canton. This proposal aims to build that missing financial primitive layer.
The system will enable banks, asset managers, and credit issuers operating on Canton to:
- Separate ownership of notional principal from rights to coupon or yield flows
- Transfer yield rights independently of underlying credit exposure
- Execute credit swap–like workflows with confidentiality and counterparty restrictions
- Programmatically route yield streams across regulated participants
- Preserve privacy while maintaining synchronized settlement
This framework is intended to support tokenized bonds, syndicated credit, private credit instruments, structured notes, and other fixed income products deployed within Canton domains.

Motivation
Traditional credit markets rely heavily on structured separation of economic rights. Instruments such as coupon stripping, credit default swaps, total return swaps, and structured notes all depend on the ability to isolate principal exposure from income streams.
In public DeFi, similar primitives exist in the form of principal tokens and yield tokens. However, these implementations operate in fully transparent environments and lack the compliance controls, selective disclosure, and counterparty constraints required in regulated credit markets.
Canton provides synchronized state and privacy guarantees suitable for institutional finance, but currently lacks a reusable financial contract framework for modeling structured yield separation in credit instruments.
As tokenized private credit and fixed income products expand onto distributed ledger infrastructure, institutions require:
- Contract-level separation of economic rights
- Confidential transfer of yield entitlements
- Domain-restricted counterparty controls
- Deterministic, synchronized settlement
- Auditability without global state exposure
This proposal addresses that need by introducing a standardized, DAML-based yield segmentation toolkit purpose-built for Canton.
Proposed Architecture
The proposed system consists of a set of composable DAML templates and SDK representing credit instruments and their economic partitions.
At issuance, a tokenized credit instrument is created on Canton. This contract includes notional principal, coupon schedule, maturity terms, issuer identity, and domain participation rules. From this base contract, two derived rights are instantiated: a principal claim and a yield claim.
The principal claim represents entitlement to notional repayment at maturity and exposure to default risk. It does not entitle the holder to periodic coupon payments. The yield claim represents entitlement to scheduled coupon flows and may be transferred independently of the principal.
Each claim exists as a separate contract instance governed by Canton's signatory and observer structure. Counterparty eligibility can be enforced at the contract level, ensuring only approved participants within designated domains may acquire or hold specific claims.
Yield payments are executed through a routing mechanism implemented in DAML. At each coupon event, the system validates claim ownership and triggers synchronized settlement between relevant parties. Privacy is preserved because only participants to the contract instance observe the state transition.
This structure enables use cases such as:
- A bank retaining credit exposure while transferring yield to a treasury counterparty
- An asset manager acquiring yield rights without assuming default risk
- Structured allocation of credit income across regulated affiliates
- Confidential bilateral credit swap arrangements
The framework leverages Canton's domain model to ensure that credit positions remain private to authorized participants while still benefiting from synchronized ledger guarantees.
Example Institutional Use Case
Consider a tokenized private credit instrument issued on Canton by a regulated lender. A bank acquires the principal exposure but seeks to reduce income volatility or monetize future coupons.
Using the proposed framework, the bank separates the instrument into principal and yield claims. The yield claim is transferred to a secondary counterparty operating within the same or an interoperable Canton domain.
At each coupon date, the system automatically routes the payment to the yield claim holder, while the principal holder retains exposure to default and maturity repayment.
If structured as a credit swap, the yield holder may agree to compensate the principal holder in certain default conditions, with all obligations modeled directly in DAML and synchronized through Canton's transaction model.
Throughout the lifecycle, only relevant participants observe contract state. There is no global visibility of exposure or cash flows.
Technical Design Approach
Implementation will be native to DAML and will rely on:
- Template-based modeling of credit instruments and segmented claims
- Explicit signatory and observer definitions for privacy enforcement
- Domain-aware transfer logic to restrict counterparty eligibility
- Atomic multi-contract updates for synchronized coupon settlement
- Deterministic contract keys to prevent duplication or inconsistent claim states
Failure scenarios such as default, early termination, or restructuring will be modeled directly in the contract logic, ensuring lifecycle completeness.
The system will be modular, allowing integration with future Canton-native tokenized assets as they emerge.
Why Canton
Canton's synchronization model and selective disclosure architecture make it uniquely suited for regulated credit markets. Public blockchains cannot preserve the confidentiality required for institutional treasury strategies and credit exposure management.
This framework aligns with Canton's design principles by:
- Keeping financial state private to involved parties
- Preserving auditability without public transparency
- Enabling deterministic, multi-party financial workflows
- Supporting domain-based regulatory segmentation
By building institutional yield segmentation tooling on Canton, this proposal strengthens the network's position as infrastructure for tokenized credit and structured finance.

Market Opportunity
Global credit markets exceed $300 trillion, with private credit alone surpassing $1.6 trillion in assets under management.
As financial institutions deploy tokenized credit infrastructure, programmable primitives for structured credit markets will become essential.
The Institutional Yield Segmentation Framework enables:
- Tokenized bond markets
- Private credit funds
- Syndicated loan platforms
- Structured credit derivatives
- Institutional yield marketplaces
Strategic Value to Canton
This project strengthens Canton’s role as infrastructure for institutional tokenized finance by introducing reusable DAML templates/sdk for separating and managing principal and yield rights in credit instruments.
Structured credit markets rely on the ability to isolate economic rights such as principal exposure, coupon flows, and risk transfers between counterparties. The proposed framework provides these capabilities directly within Canton's synchronized and privacy-preserving environment, allowing institutions to structure yield distribution and credit exposure while maintaining confidentiality between participants.
By enabling programmable yield and structured credit workflows within Canton domains, the framework provides foundational infrastructure for tokenized fixed income markets, private credit platforms, and institutional treasury strategies built on the network.
Ecosystem Adoption and Institutional Distribution
Adoption of the framework will be driven through both developer tooling and active ecosystem development. The contracts and SDK developed through this proposal will be released as reusable infrastructure so issuers and financial applications building on Canton can integrate principal and yield segmentation directly into tokenized credit instruments.
In parallel, the team will actively engage institutional and infrastructure partners already exploring structured yield strategies across digital assets and real world assets. This includes tokenization platforms, staking providers, asset managers, and institutional treasury operators evaluating programmable yield flows.
Business development efforts will focus on introducing the framework to potential Canton participants and supporting early integrations. This includes:
- Working with tokenization platforms issuing credit or fixed income instruments to integrate PT/YT segmentation into their issuance models.
- Engaging institutional allocators and treasury managers exploring structured yield strategies around tokenized assets.
- Supporting asset managers and credit funds experimenting with programmable coupon distribution and credit exposure management.
- Collaborating with ecosystem builders to incorporate the framework into new financial applications deployed on Canton.
Through these efforts, the project aims to establish early institutional use cases on Canton and support the emergence of structured yield and credit markets within the network.
