As an update for the community, after checking deeper into the usage of the on-chain exchange rate of cbETH, we think more time needs to be allocated to study its pricing dynamics. So the swap of the cbETH feed will not be included in this proposal.
The final items to be included are the previously announced:
- Swap to a WBTC/BTC/ETH feed on Aave v2 Ethereum for WBTC.
- Enable the Price Oracle Sentinel on Aave v3 Optimism.
- Swap the wstETH feeds on Optimism and Arbitrum to use a wstETH/ETH/USD price sync adapter. Important, the wstETH/ETH component by Chainlink doesn’t use the “primary market” rate, as it is not available on the L2s. But the swap to a price sync adapter is a net positive improvement.
- Swap the stMATIC and MATICx feeds on Aave v3 Polygon to use their on-chain exchange rates.
