What it offers

• depositToSDAI: Deposit DAI into Savings DAI vault (ERC-4626)
• withdrawFromSDAI: Withdraw DAI from sDAI vault by asset amount
• redeemFromSDAI: Redeem sDAI shares for DAI

​

Notes

• sDAI earns DSR yield (ERC-4626 compliant)
• DSR yield accrues automatically - sDAI appreciates against DAI over time
• Approve DAI to sDAI contract before depositing
• Pot is the internal DSR accumulator - chi() tracks the accumulated rate
• USDS is the rebranded DAI stablecoin
