There are 2 main ways I can think of right now, but they each differ:
1) Deposit any other stablecoin into AAVE/(a decentralized lending platform) as collateral, borrow USDT from there, & sell USDT for another stablecoin.
This method (semi-unfortunately) allows for rehypothecation: If you're ultra-convinced USDT will fail, it makes sense to do the above sequence again, this time using the received stablecoins that you now have from selling USDT. The risk is massively increased with each iteration of that sequence.
2) Insurance contracts, wherein you deposit funds into a pool that watches USDT's price. If the peg breaks, the funds from the other pool that bet against you will be used to pay for the rewards, and vice versa.
Y2K finance has this in place, wherein there are 2 pools to choose from for each stableasset: One that pays out if the peg stays stable, and another if the peg breaks. This method is great for insuring stableasset values, & helps to provide downside protection.
