Looking for best single sided realyield on ETH, ARB or OP

I'm interested to know where y'all think the best place to earn realyield is on either mainnet, Arbitrum or Optimism. I'm only interested in stables USDC, crvUSD, and/or USDT. Not super interested in DAI or others really. Currently on mainnet, I know that Convex offers pretty good/safu vaults that provide rewards for Curve pools. And am in a couple there, but claiming the rewards is sometimes gas prohibitive. I used to be in a couple on Arbitrum, but those yields really went down lately. On Optimism, Yearn had pretty good yields for a while, but as more people entered, it really went down. So what's the current hotness that's safe enough to enter, but degen enough to feel like I'm actually getting better returns than just buying Treasury bonds. I'm not really looking to be in the crazy pools with really stupid unrealistic returns of 50+% but something higher than like 3% would be cool. I know, I know DYOR and NFA and all that, just looking for a few things to research and maybe try out.
