Gate News, March 12 — Sonic Labs (formerly Fantom) announced the launch of its native network stablecoin, US Sonic Dollar (USSD), as the core liquidity layer of the Sonic ecosystem. USSD is built on Frax Finance’s GENIUS compliant frxUSD infrastructure and is backed by institutional reserves. Its reserve assets are pegged 1:1 to the US dollar and consist of tokenized U.S. Treasury products provided by institutions such as BUIDL from BlackRock, USTB from Superstate, and WisdomTree. USSD aims to capture underlying layer yields and return them to the ecosystem for token buybacks and user incentives. The stablecoin supports zero-fee minting across more than 10 chains via LayerZero, including Ethereum, Base, and Arbitrum. Users can exchange assets like USDC and USDT on a 1:1 basis and redeem across multiple chains flexibly through the CCTP protocol.
