According to CoinMeta, based on the proposal from BA Labs, the risk advisor for the original MakerDAO lending protocol Sky, it is suggested to reduce the debt ceilings for five types of traditional collateral vaults: ETH-A, ETH-B, ETH-C, WSTETH-A, and WSTETH-B to zero, and to stop accepting new loans in order to mitigate potential security risks. Currently, there are 771 open positions in these five types of vaults, with an outstanding debt of approximately 376 million USDS, which has decreased by about 25% over the past year. If the proposal is approved, existing borrowers will still be able to make normal repayments, add or withdraw collateral, but they will not be able to borrow more funds. The existing positions will continue to be subject to the original liquidation rules.
