Layer 1 blockchain Somnia has announced the launch of its ecosystem stablecoin, USDso, which is issued and operated by the decentralized stablecoin protocol Frax Finance using the frxUSD framework. USDso employs an over-collateralization model, backed by assets such as U.S. Treasury bonds, and can be minted at a 1:1 ratio with assets like USDC. The stablecoin's revenue distribution mechanism channels reserve earnings back into the ecosystem, allocating 90% to DeFi protocols and 10% to an insurance fund. USDso is designed to support high-frequency trading, DeFi, and on-chain protocol scenarios.
