You can try HyperLiquid's HLP or Jupiter's JLP. I think there are others like Ethena's stablecoin that has some kind of yield. Also, I notice that other perp DEXes recently started LP stuff similar to that of HyperLiquid—Paradex, Vest exchange, etc). APR/APY is usually around 10-15% and you don't need to KYC too to access it.

If you want a more detailed reply, you should reply this post and I'll send a link on X (Twitter) of someone's research about top stablecoin yield farming pools.

plenty of lending protocols, like AAVE that already has extensive reputation and reliability, other alternative is morpho, even providing LP can give you good interest although there's risk of impermanent lose.
if you just look at top defis, you'd easily find vaults that offers good interest and as it's defi, they don't care about KYC.

I think AAVE is great place to start but always consider the risk as well, read their documentation thoroughly, they usually mention risks.

Investing in Hyperliquid vaults has some risk to it which can result in negative returns. In fact, the current APR for HLP is -0.39%. Over a long period of time, this vault has been profitable so it is up to you to consider the risk.

There are some time tested platforms like Compound, Curve, and Aave, which might be a safer choice but your returns will be more modest.

Do not take what I am going say to you as an investment advice, it's just an old experiment of me but if you want to adopt it, it's at you own risk.
On the trust wallet app, there is an option that allows you to stake some coins easily on that wallet but some of the coins that you can stake on are  not stable coins and you know the risk already, you can buy those coins and during the bear market, the price will dip hard, secondly trust wallet is not an open source wallet, thirdly your wallet can get compromised if you are always online and visiting different phishing sits.
List of coins that I know you can stake on that wallet are; BNB, ETH, Solana, TRX, etc you can discover other.

The picture below is an example of how it looks like and the reward.

Usually you can find it in non-custodial applications such as Trust Wallet, OKEx Wallet and others. But you need to remember that these applications are not completely open-source, so get involved at your own risk.

in fact I stayed away from it because it's not open-source
