-### Avalon Finance for sUSDa, USDa
-
-
-[Avalon Finance](https://avalonfinance.xyz) is a CeDeFi lending project that
-powers both USDa and sUSDa. The redeem rate between USDa and its yield-bearing variant, sUSDa, is retrieved from the API provided by Avalon Labs.

 ### Chainlink on B^2 Network
 
 Some token prices are retrieved from other chains Chainlink oracles.
