what's Staked USDai?
Staked USDai (SUSDAI), also referred to as sUSDai, is a yield-bearing cryptocurrency token deployed on the Arbitrum blockchain. It represents staked positions in USDai, functioning as a synthetic dollar designed to generate returns through a combination of U.S. Treasuries and collateralized loans. The protocol employs the unique CALIBER framework to ensure sustainable yields, allowing holders to earn while maintaining exposure to a stable dollar-pegged asset. SUSDAI can be analyzed via major crypto data platforms for token metrics, charts, and ecosystem integration.
