I can tell you right now that there is absolutely no safe yield in crypto currently that goes beyond 4% on a “safe” stablecoin like USDC. For truly safe (as in, huge value locked, never been hacked), the yield is more like 1.5-2%
All the high yield is in algoponzis or new protocols that carry massive protocol risk
Eh, there are CeFi lenders like BlockFi/Gemini offering 7%. It's not zero risk, but the loans are partly collateralized and the borrowers are institutional entities who aren't your everyday scammer. It's better than unsecured corporate bonds in my view.
