Deep Tide TechFlow News, March 12 — According to Crowdfundinsider, Sonic Labs officially launched its native stablecoin USSD, which is backed by U.S. Treasury bonds and positioned as the core stable liquidity source for the Sonic network.

USSD is built on the Frax frxUSD stablecoin infrastructure, with reserve assets consisting of tokenized U.S. Treasury bonds provided by BlackRock, WisdomTree, and Superstate. Users can mint USSD in a 1:1 ratio with USDC and redeem it for USDC through chains that support CCTP. Compliant users who meet KYC/AML requirements can also directly convert the stablecoin into USD and transfer it to their bank accounts.

Samuel Harcourt, a core contributor to Sonic Labs, stated that USSD is a foundational step in their vertical integration plan, aimed at introducing institutional-grade yields and establishing external revenue streams beyond the S token.
