remember those HUGE repo markets that I talked about? US bonds/treasuries are the favorite collateral for those transactions and that’s why they’re not going away anytime soon but of course, the financial system is slowly diversifying
repo markets are HUGE - about the size of USD M2! they underpin the global financial system however, there’s not many DeFi protocols addressing this part of the market i may pick it up in the near future if you’re working on something similar - hit me up!
