According to BlockBeats, on August 16, MakerDAO initiated a proposal on August 12 to reduce the scale of WBTC collateral to address potential risks associated with custody changes. The proposal has been approved and executed. The changes include the following adjustments to the core vault and SparkLend platform:
For the core vault, the WBTC-A DC-IAM limit (maximum collateral amount) has been reduced from 500 million to 0, the WBTC-B DC-IAM limit has been reduced from 250 million to 0, and the WBTC-C DC-IAM limit has been reduced from 500 million to 0.
On the SparkLend platform, borrowing WBTC has been prohibited, and the loan-to-collateral ratio for WBTC has been reduced from 74% to 0%.
Previously, BlockBeats reported that BA Labs, a crypto risk analysis and assessment institution, indicated that the impending change in WBTC custody poses higher potential risks for WBTC collateral integration on Maker and SparkLend. If Bitgo or other related parties cannot convincingly demonstrate the security of maintaining the current WBTC collateral integration, BA Labs will consider further parameter adjustments to protect the protocol, potentially leading to the complete removal of WBTC collateral from Maker and SparkLend.
