In DeFi, there is the Maker Protocol with its stablecoin DAI and the DSR function that offers yield. However, the rates are subject to governance changes, making it less certain. It would be great to have a product that tracks Jerome Powell's actions. On the other hand, tokenized treasuries like USDC are centralized and subject to seizure. There are trade-offs between the advantages of Maker and the risks of smart contracts. Ultimately, on-chain T-bills offer a direct connection to traditional finance with minimal risks. It's like a race between DeFi and traditional finance to create the best stablecoin. This is the next evolution in stablecoins.
