I'm looking for a way to stake stable coins like USDT or USDC off any cex exchanges, I know binance exchange allows staking usdt on its exchange but I don't want to stake mine on exchange but straight from a wallet that has private key instead, anyone familiar with any?
No not possible but you could add liquidity to curve and other places though this is not exactly staking and the pegging is not the most accurate. Meaning that depending on which way the pool reduces you could end up losing (as well as earning) something quite different from staking whew you just earn tokens on top of your original ones. I don't recommend using any before DYOR, especially since pool liquidity can be a little tricky to wrap your head around
