Summary

Fail to update token's timestamp for each token individually

Vulnerability Details

In RAACHousePrices, we will update the RWA asset's price. According to the comment in the function setHousePrice, we wish to update the RWA assets' price timestamp individually. The reason that we need token's timestamp individually, we can make use of the individual token's timestamp to check whether the RWA's price is stale or not. This is important to make sure that we should not use one stale price to trade in RAAC.

The problem is that we fail to update the RWA assets' price timestamp individually. This will cause that we cannot check the stale price correctly with this global lastUpdateTimestamp.

Impact

Fail to implement updating timestamp for each token individually. This will cause that we cannot check each RWA asset's price is stale or not.

Recommendations

Use one mapping variable to store different NFT's price timestamp.
