South Africa’s first institutional-grade rand (ZAR) stablecoin, ZAR Universal (ZARU), has launched on Arc and joined Circle StableFX as a founding currency pair. The launch gives institutions access to 24/7 programmable foreign exchange using fully reserved stablecoins and instant onchain settlement.
BlockTower issues ZARU under a licence from South Africa’s Financial Sector Conduct Authority (FSCA). The stablecoin is fully reserved and independently audited, with every ZARU backed one-to-one by South African rand held onshore.
The ZARU/USDC pair will settle atomically on Arc through Circle StableFX’s Request-for-Quote (RFQ) engine. This means both sides of a transaction settle at the same time, or neither transaction goes through. The approach aims to reduce counterparty risk typically associated with traditional foreign exchange transactions.
Circle issues USDC through its regulated entities, and the stablecoin remains fully reserved and redeemable one-to-one for US dollars. Both ZARU and USDC settle on Arc, Circle’s open Layer-1 blockchain built for financial markets, real-time money movement and programmable economic activity.
Circle said the launch brings the South African rand into institutional-grade onchain foreign exchange infrastructure.
“StableFX was built to bring institutional FX onchain, with atomic settlement, RFQ execution, and real liquidity from day one. We welcome ZARU as the first African stablecoin on the platform, bringing local regulatory oversight and the high standards of the Circle Partner Stablecoins program to institutional markets.”
— Nikhil Chandhok, Chief Product and Technology Officer, Circle
Luno will act as the primary exchange venue for ZARU/USDC liquidity. The company will provide its regulated trading infrastructure and institutional client base, while BlockTower and Circle expect liquidity to grow as institutional market makers join StableFX.
“With ZARU live on Arc Mainnet, the rand now has global institutional reach, backed one-to-one by reserves held onshore in South Africa. Programmable money supported by institutional market makers onchain, the infrastructure is now in place.”
— Vighnesh Patel, CEO, BlockTower
BlockTower designed ZARU’s reserve structure to meet institutional counterparties’ requirements and support integration with enterprise-grade global networks such as Arc.
Luno CEO James Lanigan said compliant liquidity remains essential for institutional digital asset adoption and highlighted ZARU’s combination of local regulatory compliance and global connectivity.
“Globally compliant liquidity is the foundation of any serious institutional digital asset strategy. ZARU gives institutions a ZAR-denominated settlement that meets the regulatory bar, connected to a global network they already trust. Local compliance, global reach, that’s exactly what we’ve been building towards.”
