Canton Network secures prime broker commitments for on-chain collateral acceptance

The Canton Network has transitioned from pilot programs to production-level adoption as major financial institutions formally commit to using its blockchain for collateral management. Société Générale announced in May 2026 that it will accept tokenized collateral for Prime Services clients and act as a counterparty for repo transactions, citing the network's configurable privacy as a key advantage. Marex further validated the infrastructure by completing a live on-chain repo transaction involving HIFI and DRW in June 2026. These developments are supported by a growing ecosystem of liquidity providers, including B2C2, Cumberland DRW, FalconX, and GSR, which joined the initiative to provide market-making depth. A critical component of this expansion is the partnership between Digital Asset and the DTCC, which enables the tokenization of DTC-custodied U.S. Treasuries directly on the Canton blockchain. By allowing funds to mint digital representations of Treasuries while keeping the underlying assets at the DTCC, the network enables instant margin posting and eliminates legacy settlement delays. This integration of smart contracts with ISDA Credit Support Annex terms automates collateral calls, significantly reducing manual intervention and operational risk. The involvement of the DTCC, which handles the majority of U.S. securities transactions, provides a systemic foundation that could bring thousands of institutional participants into on-chain collateral workflows.
