Protocol Data Provider

The purpose of this contract is to help integrators and developers more easily leverage the Aave Protocol data and features.
If you need development support, join the #developers channel on the Aave community Discord server.
The source code can be found on Github here.
Each market has a separate Protocol Data Provider. To get the address for a particular market, call getAddress() using the value 0x1.
