Update the Contributor-Supplied Uniswap V3 $MCB / $ARB Pair to $MCB / $USDC Pair

Context

Currently, MUX contributors supply liquidity to a Uniswap V3 $MCB / $ARB pair with a $0 - $10 range to balance the inflow and outflow. This causes $MCB price movements to have a relatively high correlation with $ARB price movements, and $MCB price movements have been affected by the high $ARB token price volatility.

Proposal

To further stabilize the $MCB liquidity situation, MUX contributors propose updating the Uniswap V3 $MCB / $ARB Pair to a $MCB / $USDC Pair. The update won’t effect the latest liquidity depth of the trading pair.
