According to BlockBeats, on August 11, MakerDAO plans to initiate a proposal to "reduce the size of WBTC collateral" in the executive vote on August 12 to deal with potential risks of changes in custody rights.

Core Treasury: Reduce DC-IAM limits for WBTC-A, WBTC-B, and WBTC-C from 500M, 250M, and 500M to 0.

SparkLend: Banned borrowing of WBTC and reduced the collateralization ratio for WBTC loans from 74% to 0%.

BA Labs said that given the upcoming changes in WBTC custody, WBTC collateral integration faces higher risks on Maker and SparkLend. If BitGo or other relevant parties cannot prove security, BA Labs will consider further adjusting parameters to protect the protocol.
