What

The following changes have been made to ensure that a reasonable amount of USDC/mUSD is purchased when liquidating COMP:

  • require sender to be non smart contract (i.e. enforce tx.origin == msg.sender)
  • add a minimum amount of bAsset (USDC) to receive per sellToken (COMP)
  • add a fix to Curve to ensure that the rate is always >= 0.95
