Objectives

Refactor the Fractional Wrapper from assignment #4 into a Proportional Ownership Flash Loan Server. It should conform to specifications ERC3156 and ERC4626.

  1. Refactor the Fractional Wrapper into an ERC3156 Flash Loan Server.

  2. Underlying: token available for flash lending.

  3. flashFee = 0.1%

  4. When users deposit underlying, the amount of wrapper tokens they receive is proportional to the ratio of their underlying deposit to the total underlying supply in the pool.

    wrapperMinted / wrapperSupply == underlyingDeposited / underlyingInWrapper

  5. Refactor to the ERC4626 specification so that it can be automatically integrated to yield aggregators such as Yearn V3.
