DRW and Marex Execute First Canton OTC Swap Using S&P Index

• DRW and Marex completed Canton’s first reported OTC swap.
• Kaiko tokenized S&P’s iBoxx corporate bond benchmark.
• Derivnex used a shared smart contract to represent the trade.
• Digital cash and collateral integration remains under development.

Trading firms DRW and Marex have completed a blockchain-based derivatives transaction using an S&P Dow Jones Indices benchmark, bringing institutional swap trading onto the Canton Network through a platform designed to reduce fragmented recordkeeping.

The October 13 announcement confirms that the firms executed a total return swap through Derivnex, an institutional derivatives platform built on Canton.

The contract references the iBoxx USD Liquid Investment Grade Index, with Kaiko providing a tokenized representation of the benchmark and distributing official index values for ongoing valuation.

The companies describe it as the first over-the-counter (OTC) swap completed on Canton and the first OTC derivative to reference a fully tokenized index on distributed ledger infrastructure.

For institutional trading desks, the immediate application concerns how privately negotiated contracts are recorded, valued and managed after execution.

How the DRW-Marex Swap Works

A total return swap allows counterparties to exchange payments linked to the performance of a reference asset or index without transferring ownership of that asset.

The arrangement typically involves one party receiving the reference asset’s total return while paying a financing rate, although the companies have not disclosed the specific payment terms of this transaction.

Here, the reference asset is a corporate bond index rather than a cryptocurrency.

The iBoxx USD Liquid Investment Grade Index measures the performance of U.S. dollar-denominated investment-grade corporate bonds from developed markets. Its methodology includes minimum issuance-size requirements, maturity criteria and issuer concentration limits.

Four participants supported the transaction:

• DRW and Marex: The trading counterparties, with DRW acting as the swap counterparty and Marex as the provider.
• S&P Dow Jones Indices: The benchmark administrator supplying the underlying index and official values.
• Kaiko: The data provider responsible for tokenizing the benchmark and distributing signed index information.
• Derivnex: The platform representing the contract as a smart contract on Canton and providing a shared record for lifecycle management.

The underlying corporate bonds were not tokenized or transferred as part of the swap.

Instead, the blockchain-based representation concerns the index information and the derivative referencing it. This allows the counterparties to obtain contractual exposure to the benchmark without directly holding its constituent securities.

What Changes for an Institutional Derivatives Desk?

The operational significance becomes clearer after a swap has been executed.

Unlike an ordinary securities purchase, an OTC derivative can require ongoing valuations, payment calculations, amendments and eventual termination.

Both counterparties need consistent information about the contract’s terms and current status.

In conventional infrastructure, firms may maintain separate records across trading, risk management and back-office systems. Differences in how transactions or subsequent events are recorded can require reconciliation.

Consider a swap whose valuation depends on a daily benchmark update.

If counterparties process different index values or record a contractual event at different times, their internal positions may no longer agree. Operations teams must then determine whether the discrepancy comes from market data, contractual interpretation or processing.

Derivnex addresses the recordkeeping component by placing the transaction’s terms into a shared smart contract.

The platform also incorporates the Common Domain Model (CDM), a standardized framework for representing financial products, transactions and lifecycle events.

According to the International Swaps and Derivatives Association, the CDM provides a common machine-readable structure intended to improve interoperability between financial systems and reduce reconciliation work.

The combination of shared infrastructure and standardized trade representation could reduce differences arising from incompatible records.

It does not automatically eliminate valuation disputes, operational errors or disagreements over contractual obligations.

DRW founder and CEO Don Wilson emphasized the operational aspect in Canton’s accompanying announcement, saying the firms can now work from the same record.

That is a more immediate benefit than the prospect of replacing the entire derivatives settlement process.

Kaiko Brings Licensed Index Data Onchain

The transaction also addresses a less visible challenge in institutional tokenization: distributing proprietary financial information within blockchain-based applications.

Market benchmarks are generally subject to licensing agreements that determine who can access their data and how that information may be used.

Kaiko’s tokenized iBoxx representation incorporates access permissions and usage rules intended to preserve S&P Dow Jones Indices’ intellectual-property controls.

For the swap, Kaiko also distributed signed official index values used by Derivnex to calculate the position’s ongoing valuation.

This provides a mechanism for authorized counterparties to consume benchmark information within a digital derivatives workflow.

It is different from publishing unrestricted index data on a public blockchain.

The structure allows the benchmark administrator to maintain commercial and governance controls while supporting a new method of distributing information to financial applications.

That capability may be relevant to other derivatives linked to licensed indices, particularly where several institutions need access to consistent reference data.

However, the announcement does not establish that the same infrastructure has been deployed across additional benchmarks or trading relationships.

Onchain Trade Records Are Not the Same as Cash Settlement

The completed transaction demonstrates blockchain-based trade representation and benchmark integration, but the companies have not established that its associated payments or collateral transfers were settled on Canton.

Derivnex plans to connect managed positions with digital cash and collateral in a later development phase.

Such an integration could allow contractual payments, margin movements and collateral transfers to operate alongside the trade record.

The distinction matters because derivatives infrastructure performs several functions beyond recording an agreement.

Counterparties must also manage exposure, exchange collateral where required and settle payments as obligations arise.

Canton has already supported transactions involving more integrated settlement arrangements.

In June, HIFI, DRW and Marex completed an onchain repurchase transaction involving U.S. Treasuries and digital cash.

HIFI provided the cash leg, DRW supplied the Treasury securities and Marex acted as prime broker. According to the announcement, the transaction achieved simultaneous settlement of both legs.

That earlier transaction concerned secured financing, while the October swap focuses on the ongoing management of a derivatives contract.

The two developments address different operational requirements. Integrating those capabilities could eventually support more complete institutional workflows, although that outcome has not been demonstrated by the latest swap.

The Commercial Test Comes After the First Trade

The transaction establishes that DRW and Marex can use a tokenized benchmark within a live derivatives agreement represented on Canton.

Its commercial significance is harder to assess.

The participants have not disclosed the swap’s notional value, maturity, financing rate or collateral requirements.

They also provided no quantitative evidence of reduced processing costs, shorter reconciliation times or lower operational risk.

Those omissions limit comparisons with conventional OTC trading infrastructure.

A single completed transaction demonstrates technical feasibility, but sustained adoption would require the platform to support repeated trading activity, multiple counterparties and more complex contractual events.

Derivnex has identified equity and index derivatives, including basket and single-name products, as its initial areas of focus.

Expanding into those instruments would test whether the same approach can accommodate different valuation methods, lifecycle events and counterparty requirements.

The more meaningful indicators will be the number of active trading relationships, the volume of contracts managed through the platform and measurable changes in post-trade processing.

For S&P Dow Jones Indices and Kaiko, the transaction establishes a new use for licensed benchmark data. For Derivnex, it provides a live example of shared derivatives recordkeeping.

The next challenge is demonstrating that the infrastructure can deliver consistent operational benefits across a larger trading business.
