Who's set up an oracle for token prices on Base? How'd you do it and would you recommend the approach, sanity wise?

Surprised there weren't more comments! 

We haven't built an oracle, but at /indexing we've used onchain swap pools to get surprisingly accurate prices for tokens (e.g. VWAP). It mostly takes a little finagling to find + decode all the pool variations

I imagine a very similar approach could be used for an oracle - happy to chat any time if it helps!
