[Port3 Network Attacked Due to Vulnerability in Cross-Chain Token Solution] Port3 Network released an incident report on Platform X, pointing out a boundary condition validation vulnerability in the CATERC20 cross-chain token solution adopted by the NEXA Network. The report indicates that after token ownership is renounced, the function's return value becomes 0, which aligns with the ownership verification condition, leading to a failure in ownership checks and potentially causing unauthorized access. The audit report for CATERC20 did not mention this issue, and Port3 tokens, having renounced ownership to achieve greater decentralization, are in a vulnerable state.

[Tom Lee: October 11 Crypto Market Crash Triggered by Abnormal Drop in USDE Leading to Auto Liquidations] On November 23, Tom Lee stated in an interview that the crypto market crash on October 11 was caused by an abnormal drop in the USDE price on a certain trading platform to $0.65 (while other platforms maintained the $1 peg), triggering the auto-deleveraging mechanism (ADL) and resulting in the forced liquidation of numerous accounts. Due to insufficient liquidity on the platform, the liquidations caused a chain reaction that affected the entire market, leading to the liquidation of a large number of crypto accounts in a short period. Tom Lee pointed out that this incident stemmed from the trading platform's failure to collect cross-platform price data, relying instead on an internal pricing system, which exposed code vulnerabilities and systemic risks. He also mentioned that this event significantly reduced the capital of market makers and trading institutions, creating a vicious cycle. Tom Lee emphasized that the essence of DeFi lies in code vulnerabilities and leverage risks, and investors should not abuse leverage.
