OpenEden offers a smart contract vault managed by a regulated entity, providing 24/7 access to U.S. Treasury Bills (T-Bills) through the OpenEden TBILL Vault. This on-chain liquid pool allows stablecoin holders to earn sustainable yields by investing in T-Bills, which are backed 1:1 by T-Bills, USD Coin (USDC), and U.S. dollar reserves. Investors gain exposure to short-dated T-Bills via the TBILL token, receiving returns based on the underlying assets in a secure, bankruptcy-remote special purpose vehicle.
