BGD. Correlated-asset price oracle

Development
5

As an update of the project, we have progressed the implementation and, after the feedback from the community and risk providers, the next steps are the following.

  • There is clear consensus that upper price protections for LSTs and stable-coins are a net improvement, and the initially proposed design, sound. Therefore, in order to prioritise delivery speed, we will proceed with an initial release applying those upper protections, leaving lower bounds for the following iteration (scheduled just after the first, as the security procedures will be simpler).

  • In order to reduce complexity, the correlated-asset price oracle will be applied initially on all the Aave v3 instances, with v2 left for the following iteration.

  • The assets to apply the solution on are the following:

    Aave v3 Ethereum

    USDT, USDC, rETH, DAI, cbETH, sDAI, LUSD, FRAX, crvUSD, wstETH

    Aave v3 Polygon

    MATICx, USDC.e, USDC, stMATIC, USDT, DAI, wstETH, agEUR

    Aave v3 Avalanche

    sAVAX, USDC, USDt, DAI.e, FRAX

    Aave v3 Optimism

    wstETH, USDC.e, USDT, sUSD, USDC, DAI, rETH, LUSD

    Aave v3 Arbitrum

    wstETH, USDC, USDT, USDC.e, DAI, rETH, LUSD, FRAX, EURS

    Aave v3 Metis

    m.USDC, m.USDT, m.DAI

    Aave v3 Base

    cbETH, USDbC, USDC, wstETH

    Aave v3 Gnosis

    wstETH, sDAI, xDAI, USDC, EURe

    Aave v3 BNB Chain
    USDC, USDT

  • Given their purely technical/risk nature, the final initial configurations will be defined at AIP stage, as they will based mainly on historic data on each one of the assets. We will request the risk providers of the community to recommend the most appropriate ones.

  • We will proceed now with the creation of an ARFC Snapshot, while the security procedures on the solution are finished.
