Venus Protocol has temporarily set the loan-to-value (LTV) ratio for the BAL market on Ethereum to zero following reports of a hack on Balancer. This precautionary measure suspends all new lending and borrowing activities using BAL as collateral until system stability is confirmed. Existing positions remain unaffected with a liquidation threshold of 59%. Users are advised to monitor their positions closely and consider repaying loans or adding collateral to maintain security.
