There has been arguments that either/all BUSD, TUSD or PAX could benefit from metapools.
Right now gas is over 100 Gwei which has on and off been the norm for several months.
A swap in one of the old pools costs ~$35, a Metapool swaps costs ~$13 (at 20 Gwei, ~$7 vs ~$2.5). For those not familiar, as the older pools are lending pools, they are more expensive to interact with.
As a result those tokens could receive a great amount of small and medium swaps as a result of having good liquidity in a metapool.
We are proposing to test out a metapool on one of those coins to observe if it has a positive effect on volume and liquidity.
BUSD, TUSD and PAX are three medium-large cap stables and currently do not have a gas optimised solution on Curve. In order of volume, TUSD is by far the largest, followed by BUSD and PAX which tends to vary heavily.
Potentially more small/medium swaps
Will dilute liquidity
