Overview
U is a meta-stablecoin protocol that functions as a basket of other stablecoins — primarily USDT, USDC, and DAI — held in optimized proportions to provide yield, peg stability, and diversification. Rather than backing U with raw USD or crypto collateral, the protocol holds productive stablecoins that earn yield, passing the blended return to U holders. Think of it as a stablecoin index fund, providing exposure to the stablecoin market with built-in diversification.
Who Created U?
U was created by United Stables Protocol and launched in 2024. It is a Meta / Basket stablecoin designed to maintain a stable value pegged to the US dollar.
Key Features
- +Basket design provides automatic diversification across USDT, USDC, and DAI
- +Yield-bearing by default — deposited stablecoins earn money market rates without user action
- +Reduces counterparty concentration risk from holding any single stablecoin
- +Native yield accrual means U appreciates relative to underlying over time (like cUSDC)
- +Protocol-level risk management with automated rebalancing to cap single-asset exposure
- +Composable in DeFi — can be used as collateral on protocols that accept it
Where to Use U
U is available on Ethereum, Arbitrum, Optimism and 1 other networks. You can use it on centralized exchanges for trading, in DeFi protocols for lending and borrowing, or as a stable store of value to park funds between trades.
