What does Saber use?

Could you elaborate on the technologies and platforms that Saber utilizes in its operations? I'm particularly curious about the blockchain protocols and smart contract frameworks that it employs, as well as any unique or innovative tools that contribute to its functionality and performance. Additionally, I'm wondering if Saber leverages any decentralized finance (DeFi) protocols or decentralized applications (DApps) in its offerings.
