❓ Why would this big brother choose to borrow USDC via AAVE? He’s losing money!

I guess he definitely didn’t find the correct way to use Spark @sparkdotfi—
In sparklend, you can directly borrow USDS at a low interest rate, then swap it 1:1 into USDC through the built-in PSM feature.
In other words, by taking on cheaper USDS debt within the Sky system, you get the same dollar liquidity that’s available in the external market.
Based on the current interest rate spread, he can save close to 10% in costs!
Many protocols have the PSM feature, but usually it’s just a dual-asset exchange contract that lets users swap stablecoin A and the protocol stablecoin B via a fixed-price swap to help the peg return.
What’s better about Spark’s PSM is that it’s not an isolated module—it uses both depth and scheduling, handling conversions across USDC ↔ USDS ↔ sUSDS at the same time.
Current on-chain data shows that Sky/Maker’s Lite PSM treasury holds nearly 4 billion USDC, far exceeding the fillable capacity of most protocol PSMs—so users can reliably enter and exit yield products~
Have you learned this little trick?
