Sonic Labs (formerly Fantom) has officially launched its network-native stablecoin, US Sonic Dollar (USSD), serving 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-grade reserves. Its reserve assets are pegged 1:1 to the US dollar and consist of tokenized US Treasury products from institutions such as BlackRock's BUIDL, Superstate's USTB, and WisdomTree. USSD aims to capture base layer yields and return them to the ecosystem for token buybacks and user incentives. The stablecoin supports zero-fee minting on over 10 chains, including Ethereum, Base, and Arbitrum, via LayerZero. Users can exchange it 1:1 with assets such as USDC and USDT, and it supports flexible redemption across multiple chains via the CCTP protocol.
