Toronto, Ontario--(Newsfile Corp. - May 21, 2026) - Stablecorp Digital Currencies Inc. ("Stablecorp"), a Canadian digital asset infrastructure company acting on behalf of QCAD Digital Trust (the "Trust") in its capacity as servicer of the Trust, today announced that it has issued QCAD on Arc testnet and integrated with StableFX, Circle's institutional-grade stablecoin FX engine. The QCAD/USDC pair is available in the StableFX sandbox environment, demonstrating how Canadian dollar stablecoin liquidity will move onchain. This integration will transition to production following Arc mainnet launch, expanding stablecoin-based FX infrastructure for CAD/USD flows within the Arc ecosystem.

Arc is the open Layer-1 blockchain developed by Circle and designed to bridge onchain innovation with real-world economic activity. As one of the first Canadian dollar stablecoins issued on Arc testnet, QCAD demonstrates how it can work together with Arc and StableFX to support global onchain finance through stablecoin-based FX, predictable fees, and deterministic settlement.

Redefining Foreign Exchange with StableFX

StableFX allows financial institutions, payment processors, and corporate treasuries to efficiently execute large-scale currency conversions between fully-reserved stablecoins, including QCAD and USDC.

"Our integration into Arc testnet represents the next evolution of Canada's digital economy," said Patrick Mandic, Chief Technologist at Stablecorp. "Integrating QCAD into StableFX isn't just about enabling a new trading pair, it's about building a faster, more efficient digital backbone for the $150 billion daily USD/CAD corridor; an infrastructure to accelerate the migration of institutional FX onto on-chain rails."

"Working with Stablecorp to support QCAD's integration with StableFX on Arc testnet helps expand more efficient onchain CAD and USD foreign exchange use cases," said Nikhil Chandhok, Chief Product and Technology Officer at Circle. "This reflects the growing opportunity to use stablecoins and open blockchains to enable more efficient infrastructure for real-world financial applications."

Efficient, Direct, Compliant

For institutions, the combination of QCAD and StableFX offers distinct advantages over traditional FX markets:

• Minimal Settlement Risk: Utilizing Payment-versus-Payment (PvP) atomic settlement, StableFX exchanges QCAD and USDC in near-real time. This minimizes the risk of counterparty default during the settlement window.
• Capital Efficiency: Removes the requirement to pre-fund multiple foreign nostro accounts with idle cash. Instead, liquidity can be mobilized internationally on-demand, aligned with real-time payment and settlement needs.
• Liquidity availability: The T+0 (instant) settlement cycle allows corporate treasurers to deploy capital immediately, rather than having funds trapped in the T+2 clearing process of legacy banking networks.
• Programmable Compliance: Arc's architecture supports "opt-in privacy". QCAD flows on the network are designed to support businesses to enable compliance with privacy standards.
