According to Foresight News, MakerDAO plans to launch a proposal to "reduce the size of WBTC collateral" in the executive vote on August 12 to limit the growth of WBTC collateral and reduce risks. In terms of the core vault, the proposal is to reduce the WBTC-A DC-IAM quota (maximum collateral) from 500M to 0; reduce the WBTC-B DC-IAM quota (maximum collateral) from 250M to 0; and reduce the WBTC-C DC-IAM quota (maximum collateral) from 500M to 0. SparkLend: Prohibit borrowing WBTC; reduce the loan collateral ratio of WBTC from 74% to 0%. BA Labs, a crypto risk analysis and assessment agency, said that given the upcoming change in WBTC custody, WBTC collateral integration faces higher risks on Maker and SparkLend. If BitGo or other parties cannot convincingly demonstrate the security of maintaining the existing WBTC collateral integration, BA Labs will consider further adjusting parameters to protect the protocol until WBTC collateral on Maker and SparkLend is completely removed. BA Labs believes that the above actions are taken to limit the growth of WBTC exposure and address potential risks brought about by changes in WBTC custody.
