We are excited to announce the launch of ZEN USD (symbol: ZUSD), the first natively-issued USD stablecoin, on the Horizen EON network, a fully EVM-compatible sidechain and smart contract platform powered by Horizen that is built with massive scalability in mind.

What is ZUSD

ZUSD is a fully-backed stablecoin created in collaboration with Stably, a venture-backed FinTech company that offers regulatory-compliant Stablecoin-as-a-Service (SCaaS) and fiat ramp infrastructure. The collateral of ZUSD is held in liquid USD-denominated assets — including bank deposits, money market instruments, and USDC — by a designated trustee for the benefit of ZUSD token holders. Every ZUSD token can be minted or redeemed 1-to-1 with USD or USDC (minus fees) by users who are KYC-verified by Stably.

Administered by Stably’s Wyoming-based registered money service business subsidiary, ZUSD is issued in compliance with FinCEN’s convertible virtual currency guidance (FIN-2019-G001), including BSA/AML regulations and OFAC sanctions. Additionally, periodic attestations will be performed by an independent attestor to verify that every ZUSD token in circulation is backed 1-to-1 with collateral.

“This partnership with Stably is a major step towards achieving a more interconnected and seamless blockchain ecosystem. The integration of Stably’s stablecoin infrastructure with Horizen EON’s platform will not only enhance the user experience but also pave the way for a more robust and compliant digital asset space.”

- Rob Viglione, Co-founder of Horizen and CEO of Horizen Labs.

Why Horizen EON

The Horizen EON network, through its unique capabilities, has positioned itself as a preferred platform for innovative projects, as evidenced by the collaboration with Stably for the launch of ZUSD. Horizen EON’s notable compatibility with the Ethereum Virtual Machine allows projects to smoothly integrate tools and resources from the Ethereum ecosystem. Furthermore, EON’s commitment to scalability ensures the platform remains consistently efficient, even as adoption surges and transaction volume grows. The network’s developer-centric approach played a pivotal role in enabling Stably to deploy ZUSD on Horizen EON in just under two months.

Beyond these technical merits, Horizen EON proactively addresses challenges prevalent in other chains, including inadequate tooling, network congestion, and potential centralization pitfalls. The alignment of core values between Horizen EON and network supporters like Stably, with an emphasis on transparency, security, community engagement, and growth, underscores Horizen EON’s mission to be at the forefront of the Web3 economy.

“I’ve personally met and known Robert Viglione since 2018 and we have been talking about stablecoin collaboration for a long time. It’s great to finally make it a reality and Stably is excited to continue working together with Robert and the team behind Horizen as well as the community for many years to come!”

— Kory Hoang, Co-founder and CEO of Stably
