I’m quite sure our target audience are savvy defi users or Ethereum protocols (Harvest, YFI etc.). These two complement each other almost perfectly.
One of the greatest strengths with PERP is that defi protocols (yield optimizers) can easily integrate with the vAMMs. This will ensure that the funding rate is attractive for traders and that the price is always close to market price.
This would suggest supporting ERC-20 tokens that are broadly used in defi protocols. Personally, I would like to see other L1 tokens, e.g. LTC, DOT or even XRP, but I’m not sure there is a market for this. It will not be composable with other defi protocols.
I agree with @tongnk metrics, given that we are going for ERC-20 tokens in the beginning. If we list other L1 tokens or even stocks, then we must come up with other metrics.
