Sonic Labs launches USSD stablecoin backed by BlackRock and WisdomTree U.S. Treasury assets

Sonic Labs has launched USSD, a USD-pegged stablecoin supported by tokenized U.S. Treasury assets, adding a new source of stable liquidity to the Sonic blockchain ecosystem.

The new stablecoin, announced on March 9, will serve as a dependable on-chain dollar across the network. It can be used for trading, lending, payments, and settlement in decentralized finance applications running on Sonic.

Sonic Labs said the launch gives developers and users a stable asset that can move easily across DeFi platforms within the network.

Institutional Treasury backing

USSD maintains a 1:1 backing with high-quality U.S. dollar assets held with regulated custodians. The reserves include tokenized Treasury products linked to major financial institutions such as BlackRock, Superstate, and WisdomTree.

These tokenized Treasury funds bring traditional financial instruments into blockchain markets while maintaining transparency and stability on-chain. Sonic Labs says the reserve structure follows the same framework used by Frax (FRAX), which focuses on clear redemption mechanics and dependable backing.

Users can mint USSD through non-custodial smart contracts on the Sonic network. Supported dollar-based assets may be deposited at a one-to-one ratio, and the minting process carries no fees.

The structure makes it easier for liquidity providers and DeFi participants to enter the ecosystem without additional costs.

Cross-chain liquidity and Sonic’s DeFi strategy

USSD launches with cross-chain minting support from more than ten blockchain networks. A user can deposit assets on another chain and receive USSD directly on Sonic, allowing liquidity to move between ecosystems with fewer barriers.

Through Frax’s cross-chain infrastructure, the stablecoin can also be exchanged for supported dollar assets. This setup enables users to settle transactions, transfer money between networks, and manage liquidity without depending on fragmented markets.

Stablecoins often serve as the main currency for DeFi, supporting trading pairs, collateral for lending, and settlement in derivatives markets.

A native stablecoin will help keep liquidity within the Sonic ecosystem and gives applications a consistent dollar reference. Revenue generated from the Treasury assets backing USSD may later support ecosystem incentives and network development as activity on Sonic continues to grow.
