Getting APY values from AAVE.

Real-time APY values are fetched from community hosted AAVE graph explorer: https://api.thegraph.com/subgraphs/name/aave/protocol-v3-polygon with query:

{
      reserves {
        id
        name
        price {
          id
        }
        liquidityRate
      }
    }

This helps us to maintain distribution/re-distribution algorithms and up to date UI that tracks most recent APY updates on AAVE platform.

There is secondary mechanism in place in case this URL fails which is we fetch data directly from AAVE contracts. Currently this requires some manual computations but in future will be automated.
