Canton Weekly News — Treasury Settlement Goes Real-Time

Tradeweb, Franklin Templeton and Virtu completed a transaction in which a U.S. Treasury security was exchanged for tokenized cash in real time and outside normal market hours; the network's Logical Synchronizer Upgrades went live so upgrades no longer take Canton offline for hours; and governance approved Token Standard V2. On the apps side, payments infrastructure firm HIFI moved its Canton integration from pilot into production. And Interstice Digital is introducing its Cross-Chain Swap Engine, a fully non-custodial way to swap Canton Coin into ETH or USDC, or on-ramp into Canton using either.

Swapping between Canton and Ethereum just got easier.

Introducing the Interstice Digital Cross-Chain Swap Engine, a way to swap Canton Coin into ETH or USDC, or on-ramp into Canton using ETH or USDC. It is fully non-custodial, so Interstice Digital never takes custody of your crypto at any point in a transaction, and every counterparty is screened for KYC/KYB before a swap, with the choice to accept or reject them yourself. It connects with major wallets through WalletConnect and settles across USDC, CC, and ETH. Interstice Digital

Top Stories

U.S. Treasuries settled in real time on Canton. Tradeweb, Franklin Templeton and Virtu Financial completed the first real-time, on-chain U.S. Treasury transaction executed on Tradeweb, settling a tokenized Treasury against tokenized cash (called USDCx) outside traditional market hours. Tradeweb handled execution and price discovery, while Canton coordinated both sides of the trade so the security and the cash changed hands at the same moment, with no waiting on bank wires to clear. Franklin Templeton transferred the tokenized Treasury to Virtu in exchange for the tokenized cash. Blockdaemon, Digital Asset and Societe Generale also took part. The trade shows institutions can move both a bond and its payment together, in real time, at hours when traditional markets are closed. Tradeweb / Businesswire

Canton can now ship upgrades without network downtime. Canton's Logical Synchronizer Upgrades are now live on version 3.5, ending the multi-hour network downtime that used to come with protocol upgrades. New infrastructure now runs in parallel while the network upgrades, and when it is time to switch over the transition happens automatically in seconds or minutes, with applications continuing to run uninterrupted. Canton has completed four upgrades since its main network launched, each requiring hundreds of participants to coordinate, so this removes real friction going forward. For institutions that cannot tolerate planned outages, always-on upgrades are a genuine operational unlock. Canton Network

Cartoon governance approves Token Standard V2. Canton governance approved the Token Standard V2 (tracked as CIP-0112), the next version of the network's shared rules for how tokens behave. It adds privacy-enhanced batch settlement, a new account model that gives clearer records of who owns what, and committed allocations that let trades be pre-funded before they execute. It is fully backwards-compatible with V1, so tokens already issued keep working without changes. The standard was one of the headline items in Canton's June ecosystem update. Canton Foundation

Apps on Canton

HIFI, a stablecoin payments platform, moves from pilot to production on Canton. HIFI, a payments infrastructure company whose software moves stablecoins across banks and blockchains, moved its Canton integration from pilot into production. The setup lets institutions send stablecoin payments that settle privately on Canton without exposing payment flows, counterparty relationships, or treasury balances to the rest of the network. Developers use HIFI's existing interface, so they write no Canton-specific code and run no network nodes of their own. It is a concrete example of a payments company putting Canton to work for real transactions rather than a test. Canton Network / HIFI
