Sonic Labs launches USSD stablecoin backed by US Treasury assets

Sonic Labs has launched a new stablecoin, USSD (US Sonic Dollar), designed as the stable liquidity layer for its ecosystem. This network-native U.S. dollar stablecoin is built on Frax Finance’s infrastructure and is backed 1:1 by short-term U.S. Treasury bills issued by reputable firms such as BlackRock, Superstate, and WisdomTree. With features like zero minting fees and permissionless access, USSD aims to enhance adoption and serve as a critical component of Sonic’s vertical integration strategy for improved liquidity.

BlackRock: BlackRock manages vast portfolios of traditional and tokenized assets, including on-chain U.S. Treasury products for institutional use. It provides U.S. Treasury bills that contribute to the 1:1 backing of Sonic Labs’ USSD stablecoin. This involvement bridges traditional finance with the Sonic ecosystem’s liquidity needs.
Sonic Labs: Sonic Labs develops the Sonic blockchain, an EVM-compatible layer-1 network optimized for high throughput and low latency in DeFi applications. The team launched USSD, a native USD stablecoin designed as the foundational stable liquidity layer within the Sonic ecosystem. This initiative advances their vertical integration efforts using external infrastructure and backing.
Superstate: Superstate specializes in blockchain-native asset management, focusing on tokenized U.S. Treasuries and yield-bearing stablecoin alternatives. Its Treasury assets form part of the reserves backing Sonic Labs’ USSD stablecoin. The partnership supports USSD’s role as a secure, native stable asset on Sonic.
WisdomTree: WisdomTree offers innovative ETFs and structured products, extending into tokenized assets and crypto-related investments. It supplies U.S. Treasury bills as collateral for the 1:1 backing of the USSD stablecoin launched by Sonic Labs. This enhances the stablecoin’s credibility within the Sonic ecosystem.
Frax Finance: Frax Finance operates a suite of decentralized stablecoins and lending protocols emphasizing algorithmic and collateralized stability mechanisms. It supplies the core infrastructure powering Sonic Labs’ newly launched USSD stablecoin. The collaboration enables permissionless minting and cross-chain functionality for USSD.
