Now the real question is whether bankruptcy would topple USDC since Coinbase is one of the major backers [0]. It's holding steady right now, but so was UST a few days ago. USDC has $48B supply and is propping up DeFi apps on many other networks (just look at AAVE [1] and Curve [2], two multi-chain protocols), so if it falters, there could be massive fallout.
