SKY is a governance token, which is like a digital voting share, for Sky Protocol. This system launched in 2024 as a rebrand and upgrade of the older Maker Protocol. Sky Protocol’s main value lies in giving users a simple, secure way to trade, save, and earn rewards without ever giving up control of their funds. It is built around a stablecoin called USDS, which is always worth one US dollar, but it is completely decentralized.
