Sonic Labs Unveils USSD Stablecoin as Network Looks to Reverse Decline

Key Takeaways

• Sonic TVL fell to $34M, 97% drop.
• USSD stablecoin built on Frax frxUSD infrastructure.
• Backed by BlackRock, Superstate, WisdomTree.
• Zero minting fees, multi‑chain support across ten networks.
• Aims to internalize liquidity and boost ecosystem incentives.

Summary

Sonic Labs has launched USSD, a native stablecoin built on Frax’s frxUSD framework, to shore up liquidity after its TVL collapsed to $34 million—a 97% decline from its 2025 peak. The token is fully dollar‑pegged, fee‑free to mint, and backed by institutional investors including BlackRock, Superstate and WisdomTree. USSD can be minted across more than ten blockchains, linking assets like USDC, USDT, PYUSD and tokenized Treasuries. Sonic positions the stablecoin as a structural fix to re‑centralize liquidity and revive ecosystem incentives.

Pulse Analysis

Sonic Labs’ decision to issue its own stablecoin comes at a moment of acute stress for the blockchain, whose total value locked has plummeted from a $1 billion high to under $35 million. The rapid contraction reflects broader market volatility and the challenges of sustaining liquidity when a network relies on external stable assets. By introducing USSD, Sonic is attempting to create a self‑contained liquidity layer that can absorb shocks without depending on third‑party market makers, a strategy increasingly common among Layer‑1 projects seeking resilience.

USSD leverages Frax’s frxUSD architecture, offering permissionless minting with zero fees and cross‑chain operability on Sonic, Ethereum, Base, Arbitrum and seven other chains. Institutional backing from BlackRock, Superstate and WisdomTree provides a credibility boost, while the ability to mint from a basket of assets—including USDC, USDT, PYUSD and tokenized Treasury products—broadens its appeal to both retail and institutional users. The fee‑free model lowers entry barriers, encouraging developers to integrate USSD into DeFi protocols, lending platforms, and payment solutions across the ecosystem.

If USSD succeeds in capturing a meaningful share of on‑chain transactions, it could reverse Sonic’s liquidity fragmentation and stimulate new incentive structures, such as ecosystem‑wide buybacks and yield redistribution. This internal liquidity loop may also attract capital that previously shied away due to fragmented stable‑coin exposure. Competitors will watch closely, as a thriving native stablecoin could set a precedent for other struggling blockchains to adopt similar vertical integration tactics, potentially reshaping the stable‑coin landscape in the broader crypto market.
