Sonic Labs has officially unveiled its new USSD stablecoin, a digital dollar designed to be backed by U.S. Treasury securities. The project distinguishes itself by leveraging institutional-grade collateral, specifically citing BlackRock and WisdomTree as the underlying treasury providers. This launch represents a significant move into the interest-bearing stablecoin sector, aiming to combine the liquidity of blockchain assets with the stability of traditional institutional financial products. In other digital asset market developments, ClearToken has secured authorization from the UK's Financial Conduct Authority (FCA). The firm plans to roll out stablecoin foreign exchange services integrated with the Canton Network, marking a notable advancement in the institutional adoption of blockchain-based settlement infrastructure. Meanwhile, Aon is conducting trials for stablecoin-based insurance premium payments in collaboration with Paxos and Coinbase, further signaling the integration of digital assets into enterprise risk management and traditional financial workflows. These developments reflect a broader trend of bridging decentralized finance protocols with established institutional regulatory and treasury frameworks.
