ZARU is live on @arc. As a founding currency pair on @circle StableFX, the ZARU/USDC pair now trades onchain, 24/7, in fully reserved stablecoins with near-instant settlement. How it works: the ZARU/USDC pair executes through StableFX's Request-for-Quote engine and settles atomically on Arc. Both legs of a trade settle together, or neither does. That manages the counterparty risk carried by traditional FX, where ZAR settlement has depended on correspondent banking and limited trading windows. The evidence behind the pair: ✅️ Issued by @BlockTowerTech under FSCA licence ✅️ Fully reserved and independently attested monthly ✅️ Backed one-to-one by rand held onshore in South Africa @LunoGlobal is the primary exchange venue for @ZARUniversal /USDC liquidity, bringing regulated trading infrastructure and an institutional client base to the network. Investing in Crypto assets may result in the loss of capital. BlockTower SA (Pty) Ltd is an authorised FSP (55172).

As the issuer, our job is the reserve. Every @ZARUniversal is backed one-to-one by rand held onshore, FSCA-licensed, and independently attested monthly. Now live on @circle StableFX.
