Promote with Leviathan NewsSonic Labs, the team behind the Sonic layer-1 network (a rebrand and evolution of the Fantom ecosystem), has launched USSD (US Sonic Dollar), a network-native USD stablecoin built in partnership with Frax Finance and backed by tokenized U.S. Treasuries from BlackRock, Superstate, and WisdomTree. USSD is constructed on Frax’s GENIUS‑compatible frxUSD infrastructure, positioning it as a permissionless, on-chain dollar that combines DeFi-style composability with what Sonic characterizes as institutional-grade, Treasury-backed reserves. According to Sonic’s launch materials and supporting coverage, USSD is designed to act as the core stable liquidity layer for the Sonic ecosystem, serving trading, lending, payments, and other DeFi use cases on the network. The token is fully backed 1:1 by short-duration USD assets, primarily tokenized U.S. Treasury products such as BlackRock’s BUIDL, Superstate’s USTB, and WisdomTree vehicles, held with regulated custodians under the same reserve framework used by Frax. Users can mint USSD permissionlessly on Sonic and via cross-chain infrastructure from more than 10 chains, with zero-fee minting and 1:1 conversion from stablecoins like USDC and USDT, and redemptions routed through Circle’s CCTP where applicable. A key design element is that the yield on the underlying Treasuries is intended to accrue back into the Sonic ecosystem—for example via token buybacks and user incentives—rather than remaining solely with the issuer, aligning the stablecoin’s economics with Sonic’s broader vertical-integration strategy.
