I have some USDT and USDC in my portfolio that I'd want to stake in a "De-Fi" dApp without worrying about it in a long time. There are liquidity pools in Uniswap with attractive stake rates, but there's also Compound.Finance with its lending services. Both of these platforms are built on the ETH blockchain, so gas fees would be astronomically high. I've read about some platforms being compatible with Polygon (MATIC), but I'd have yet to see if it's worth the shot (especially in terms of security/reliability).
Do you know the safest way to stake stablecoins without breaking the bank? Also, do you think it's worth it? Or should I consider other options? Any suggestions and/or recommendations would be greatly appreciated. Thanks in advance.

According to the bank rules of our country, they pay 5 to 7 percent interest per annum and 15% income tax is deducted from the interest. In that case four to five percent interest is available excluding tax. But if you stake stable coins, you get 8 to 10% interest in this case, which is much more than the bank. But in this case, even if the bank gives security to our money, if you stake stable coins, you will not get the security of your money as high as the bank. So in that case if you want to get high interest you must take high risk
