Paladin - Warden Pledges contest - 0x007's results

1. variable protocalFeeRatio should be protocolFeeRatio. There are 6 cases that needs correction in WardenPledge
2. oldfee ought to be in camelCase oldFee in line 117 and line 627. This is to maintain consistency and it's quite important in L117 cause event name are used in data analytics.
3. ClosePledge event is not emitted in retrievePledgeRewards function when the pledge was closed in line 469. The purpose is also for analytics and should be updated.

if(!pledgeParams.closed) {
    pledgeParams.closed = true;
    emit ClosePledge(pledgeId);
}

4. Reward tokens with less than 18 decimals will not work well because of constant UNIT in line 22 e.g using USDC instead of DAI.
5. There are lots of typo errors in the documentation.
