occasionally i come across high yield stablecoin farms but am too washed up to take the risk

What APY are we talking about? GUSD was at near 10% before the Earn program collapsed

Ethena's sUSDE is v. high, currently >30%;  leveraged sUSDE vaults >80%. Probably only so high at this point in the cycle. USDC on Moonwell (base) is ~10% (inc. native token rewards). Morpho's Spark Dai vault is ~13%.

yeah i get it, but at the same time US interest rate >5%, Dai Saving Rates = 8%, so some of the numbers above are not crazy. trading, as with dabbling with lending/borrowing smart contracts, will incur additional costs albeit in a different form

Well, Celsius was offering 18% before melting down.

I’m personally not touching any of this. I could make those returns day trading $degen without the coins leaving my custody
