As outlined in this forum post, the release of Uniswap v3 means that the mStableDAO should consider migrating liquidity it has on v2 to v3. This motion specifically refers to liquidity in DAI/MTA that was contributed by the DAO after being ratified here by Meta Governors.
This vote assumes that DAO signers have voted to migrate the liquidity from v2 to v3 here. If this is the case, the DAO must now decide what parameters LP contribution will use.
The final parameter to be decided on is the fee model.
What fee should the mStableDAO set for the DAI/MTA liquidity on Uniswap v3?
