Sonic Labs Launches Native Stablecoin USSD, Backed by BlackRock and Other Institutional U.S. Treasury Products

Odaily News: Sonic Labs (formerly Fantom) has officially announced the launch of its network-native stablecoin, US Sonic Dollar (USSD), which serves as the core liquidity layer for the Sonic ecosystem. USSD is built on Frax Finance's GENIUS-compliant frxUSD infrastructure and features institutional-grade reserve backing. Its reserve assets are pegged 1:1 to the U.S. dollar and consist of tokenized U.S. Treasury products provided by institutions including BlackRock's BUIDL, Superstate's USTB, and WisdomTree.

USSD is designed to capture underlying yield and redistribute it back to the ecosystem for token buybacks and user incentives. The stablecoin supports zero-fee minting across more than 10 chains, including Ethereum, Base, and Arbitrum, via LayerZero. Users can perform 1:1 swaps using assets like USDC and USDT, and it supports flexible cross-chain redemptions through the CCTP protocol.
