An infrastructure error led to over $four million being swooped up by a lurking bot-maker, departure buyers excessive and dry as their collateral was taken away. In response, the Maker group voted Friday to reconstitute sure danger measures.
DeFi alternate bZx additionally halted opening new trades and loans and can go away these options offline till an audit is carried out, mentioned Bean. bZx not too lang syne switched to Chainlink following a flash mortgage assault that relied on manipulated pricing cognition. All Chainlink seers are coverage as of press time.
“The issue is that data providers can’t provide timely updates. I can query the current rate, but it’s way off from [the] actual market rate,” Bean mentioned.
