Instadapp

Summary

The proposal aims to update DEX Pool deployment logic on DEX Factory contract. This will help to resolve the low severity bug that the team spotted, related to a side feature updateRangePercents.

The issue is only limited to when the shift module is being used when tokenIn in the swap is a native ETH token. The shift module is being called via delegate call to optimize contract size as it’s a rarely used code for side features of DEX when some changes to ranges, threshold, or center price are being made.

The proposal also updates the range of WBTC-cbBTC DEX Pool and the ratio for Spark protocol on Instadapp Lite.
