Mad Meerkat (MM) Finance has a MATIC/USDC LP with 70% APR on $65M of liquidity, which is pretty bonkers but I'm sure is being funded by copious amounts of their MMF token which won't last forever (their token is also in the "pump" phase of a new protocol launch, boosting the APR. The "dump" phase can also be expected). Either way, it's a smaller protocol and will fetch a higher APR than the same pair on, say, QuickSwap no matter what.
We would be looking to move $200K of Qi/WMATIC to this LP.
