It supports gas-free minting across more than 10 chains using assets like USDC and USDT, and is currently live on a total of 12 chains including Sonic, Ethereum, Base, and Arbitrum.Background of the launch: Sonic's TVL has plummeted 97% from its peak of $1.1 billion in May 2025 to $34 million, and the native token S has also dropped about 96% from its historical high of $1.03 in January 2025, with a market cap of only $150 million remaining.Sonic stated that USSD yields will flow back into the ecosystem for buybacks and incentives, aiming to build a self-reinforcing liquidity cycle and reduce reliance on external market makers.
