Trading firms DRW and Marex have completed the first reported over-the-counter total return swap on the Canton Network, referencing a fully tokenized benchmark from S&P Dow Jones Indices. The transaction, announced on October 13, 2026, was executed through Derivnex, an institutional derivatives platform built on Canton.
The swap references the iBoxx USD Liquid Investment Grade Index, which measures U.S. dollar-denominated investment-grade corporate bonds from developed markets. Kaiko provided a tokenized representation of the benchmark and distributed signed official index values for ongoing valuation. The companies said it was the first OTC swap completed on Canton and the first OTC derivative to reference a fully tokenized index on distributed ledger infrastructure.
In a total return swap, counterparties exchange payments linked to the performance of a reference asset or index without transferring ownership of that asset. DRW acted as swap counterparty and Marex as provider, while S&P Dow Jones Indices supplied the underlying benchmark, Kaiko tokenized and distributed index data, and Derivnex represented the contract as a shared smart contract on Canton. The underlying corporate bonds were not tokenized or transferred as part of the trade.
The operational significance lies in post-trade recordkeeping. Derivnex places the transaction terms into a shared smart contract and incorporates the Common Domain Model developed by the International Swaps and Derivatives Association, aiming to reduce reconciliation work between trading, risk management and back-office systems. Don Wilson, founder and CEO of DRW, said the firms can now work from the same immutable record.
Cash settlement and collateral management are not yet live. Derivnex plans to connect managed positions with digital cash and collateral in a later development phase. The announcement did not disclose the swap's notional value, maturity, financing rate or collateral requirements. In June, DRW, Marex and HIFI completed an onchain repurchase transaction involving U.S. Treasuries and digital cash with simultaneous settlement, but the October swap focuses on lifecycle management of a derivatives contract.
Ripple's role is separate and technical. On October 5, Ripple Custody version 1.43 added support for the Canton Network, allowing institutions to store and transfer Canton Coin tokens and CIP-56 assets under a bring your own validator model. Canton remains autonomous and does not use XRP, the XRPL ledger or RLUSD stablecoin in settlements.
Some retail crypto participants criticized Canton as a private interbank network rather than a public blockchain, but the transaction provides a live example of shared derivatives recordkeeping for institutional trading desks. Future adoption will depend on more counterparties, higher contract volumes and measurable reductions in post-trade processing costs.
