We definitely need to add more long-tail assets to compete with the other Perp DEXes out there. This is a good list of initial tokens. And the list of possible tokens for discussion are good also.
I would also add for discussion: SEI, APT, INJ, RNDR, BEAM, BLUR, WLD. All are in the top 100 in market cap and have pretty good OI across the other Perp DEXes.
