Q2 has just ended, and SlowMist's quarterly report is out: 83 attacks, A loss of 755 million US dollars. This is the most tragic quarter on record. What's even more interesting is that not only small projects are being attacked. Aave suffered a $8.45 billion withdrawal run; Taiko's cross chain bridge has been relocated for $1.7 million; THOORChain shutdown for 5 weeks; Secret Network is infinitely forged; Aztec was abducted twice a week. After reading the entire report, my biggest feeling is only one sentence: Cross chain bridges are becoming the biggest systemic risk in DeFi. For every additional chain, an additional attack surface is added. Every seamless cross chain operation implies more complex trust assumptions. So the next time we hear the project party promote the multi chain ecosystem, Don't ask how many chains are supported yet. First ask: How many times has the audit been conducted? How many surveillance cameras have been turned on? Is the fuse installed? Do you think the biggest DeFi black swan in the future will come from cross chain bridges?
