Lenders should be able to view loan request and amortization schedule and buy fractional shares of loan request

Step 3: Lenders can view Loan Request and amortization schedule Once Loan Contract (at the stage of 'new request') has been deployed, lenders should be able to view the loan request on a frontend app. The frontend app should show the loan parameters that the borrower requested. The frontend app should also show the amortization schedule (i.e. repayment table). The frontend app might also show some graphs to show the declining outstanding balance.

Step 4: Lenders can fund the loan request [Needs more thought] Lender should be able to either:

• Buy fractional shares of the loan (e.g. 1000 outstanding shares) - this might be easier for routing repayments
• Contribute variable amount, as long as it is within the loan cap

For simplicity, Lender should use a stablecoin (e.g. Dai). However, given that Dai is currently trading at 0.95, we might explore fiat-collateralized stablecoins (e.g. Paxos, USDC) as an interim measure.

To dos:

• [ ] Wireframes for Lender page and viewing amortization table @onggunhao
• [ ] Use ERC-20 contract to interface with Dharma debt contract?

• Potential lenders will be able to buy shares by interacting with a smart contract via the web app
• You can view the loan parameters from the chain and put them in a nice format in the web app

To use fractional shares, somthing in the lines of this should suffice @tspoff

Loan {
...
uint blockSize
}

constructor(
        ...
        uint _blockSize,
        ...
    ) ...{
    ...
    loan.blockSize = _blockSize;
    ...
}

function getEffectiveValue(amount) internal returns (uint){
    if (loan.blockSize === 0) {
        return amount;
    } else {
        return (amount/loan.blockSize) * loan.blockSize;
    }
}

function buyTokens(address beneficiary, uint amount) public nonReentrant {
   amount = getEffectiveValue(amount);
   ...
}
