Re: Are there any good DEXes that lets you stake USDC for 6-12% per year?
If you really want to earn annually from your stablecoins in the safest way possible, just put it on CEX instead of a DEX.
At the end of the way, both CEXes and DEXes are not prone to hacking. It's just that you want to risk putting your stablecoins on an exchange for a return, or you will put it on a hardware wallet where you might not earn from it, but it's safe... well kind of, but safer than either putting on a DEX or CEX. Now if you want to put it into a DEX, I will not recommend something but Ethena is being partnered with many DEXes out there where if you put your stablecoins out there, you will earn points as well that will make you eligible towards the Ethena Airdrop. There's a risk still so just put the amount of money that you're willing to lose. I put some as well just so that I make some money thru the airdrop... or will I?

Anyway, some CEXes offers around the number that you said. If I remember correctly, Bitget and even Binance offers around that. Even MEXC does as well. Just beware of the risks though.
