Rhombus Contarcts

Rhombus is money market protocol forked from aave-v3 with little changes.

Changes

1. use latestRoundData()

aave-v3 uses latestAnswer() to fetch oracle price from chainlink aggregator. But there is no chainlink oracle in kaia network, so we use orakl network as oracle provider. Every functions that use latestAnswer() are changed to latestRoundData()

### aave-v3 uses latestAnswer() for oracle getter.

   function getAssetPrice(address asset) public view override returns (uint256) {
      AggregatorInterface source = assetsSources[asset];

      if (asset == BASE_CURRENCY) {
      return BASE_CURRENCY_UNIT;
      } else if (address(source) == address(0)) {
      return _fallbackOracle.getAssetPrice(asset);
      } else {
        int256 price = source.latestAnswer();
         if (price > 0) {
            return uint256(price);
          } else {
            return _fallbackOracle.getAssetPrice(asset);
          }
      }
  }


### rhombus uses latestRoundData() provided by orakl

    function getAssetPrice(address asset) public view override returns (uint256) {
        AggregatorInterface source = assetsSources[asset];

        if (asset == BASE_CURRENCY) {
            return BASE_CURRENCY_UNIT;
        } else if (address(source) == address(0)) {
            return _fallbackOracle.getAssetPrice(asset);
        } else {
            (, int256 price,) = source.latestRoundData(); ## change
            if (price > 0) {
                return uint256(price);
            } else {
                return _fallbackOracle.getAssetPrice(asset);
            }
        }
    }
