USDS & sUSDS

What is USDS?

USDS is a decentralized, overcollateralized stablecoin issued by the Sky Protocol.

What is sUSDS?

sUSDS is a yield-bearing stablecoin representing a deposit of USDS into the Sky Protocol’s Sky Savings Rate (SSR) module, which earns passive income.

What is the Sky Savings Rate (SSR)?

The Sky Savings Rate is an automated token-accumulation mechanism of the decentralised Sky protocol that takes into account the effect of accumulated USDS compounded in real time.

The Sky Savings Rate is variable, determined not by market factors but by Sky ecosystem governance through a process of decentralised onchain voting.
