Helper contracts to interact with some KyberSwap's protocols

Contract Architecture

InputScalingHelper: Main contract to scale the swap data of Kyber's router (MetaAggregationRouterV2), from oldAmount to newAmount of swap amount

ScalingDataLib: Library to scale swap amount of each dex in the route

InputScalingHelperL2: (For Arbitrum, Optimism) Main contract to scale the swap data of Kyber's router (MetaAggregationRouterV2), from oldAmount to newAmount of swap amount

ScalingDataL2Lib: (For Arbitrum, Optimism) Library to scale swap amount of each dex in the route

How to use

Function getScaledInputData in the InputScalingHelper contract

• Input:
  • The encoded data (including the selector) of swap and swapSimpleMode from the contract MetaAggregationRouterV2
  • The new input amount
• Output: New encoded data
• Flows:
  • Decode data of router’s description and executor’s description and scale the input amount. There are 2 cases here of swap and swapSimpleMode.
  • Decode the Swap[] data from executor’s data and use the scaling lib to scale amount of each Swap
  • Encode the new executor’s data and router’s data
• Requirements: There isn’t any RFQ swap in input data, else it will be reverted with the message “InputScalingHelper: Can not scale RFQ swap”
