Odaily News MakerDAO has passed and implemented a series of proposals yesterday, including a proposal to reduce the size of WBTC collateral. The proposal includes: the core vault will reduce WBTC-A DC-IAM (maximum collateral amount) from 500 million to 0; WBTC-B DC-IAM (maximum collateral amount) from 250 million to 0; WBTC-C DC-IAM (maximum collateral amount) from 500 million to 0; disable WBTC lending in SparkLend; reduce WBTC LTV from 74% to 0%. The proposal stated that due to the potential risk of changes in WBTC custody, the integration of WBTC collateral on Maker and SparkLend will bring higher risks, and the above actions are taken to limit the growth of WBTC exposure.
