I already made an 80/20 BANK/WETH pool: Balancer. It is an Oracle pool with delegated swap fees (i.e., we can ask Gauntlet to manage the swap fee dynamically to optimize LP returns. I initially set the fee high because it’s low liquidity).
So, one option is to just use this existing pool - and ask Gauntlet to manage fees + make a governance proposal for LP mining. Or if the community would rather have permanently fixed fees, I could withdraw from the current pool and create that one.
I’d advise against fragmenting liquidity by creating duplicate pools with different fees. Having one pool with dynamically managed fees seems like a good solution that hasn’t been considered.
It’s even possible to create an owned pool where the fees could be set dynamically through Bankless community governance, if there’s an appropriate multi-sig account to use as the owner.
