Simple Summary

This proposal activates the correlated-assets price oracle (CAPO) system for fiat-pegged stable coins on Aave V2 pools, and does extra miscellaneous updates on price feeds of Aave v2.

Motivation

To continue enhancing the security of the protocol using CAPO and to align with the recent approved proposal for Aave v3, we are introducing the activation of CAPO adapters for Aave v2 pools. As no LSTs are listed on the v2 (stETH is not applicable), we are only applying the adapters to the fiat-pegged stablecoins.

This proposal also includes an update of the oracle for DPI from DPI / ETH to DPI / USD.

Specification

Oracles will be updated using ORACLE.setAssetSource() method. Below is the list of assets per network to be updated:
