Providing liquidity in any lending protocol can manage you get good interest. I saw in AAVE their stable coin interest sometimes goes up to 12% which is pretty decent. Though this interest won't be stable, you will get it at around 5% most of the time. You can also provide liquidity in any early project that is trending in the market like BLUR. Its price goes up dramatically due to its potential airdrop from its L2 network BLAST. Its trading volume in dex also increased. Even some centralized exchange provide high APR for early project to lock up stablecoin or other major alts. This can be risky but if you can take calculated measure it can be profitable for you.
