API data service failures account for 37% of such anomalies (Downdetector 2024 statistics). When aggregators such as CoinGecko and CoinMarketCap detect that the quotations of over 30% of cooperative exchanges have been suspended for 350 milliseconds, they automatically trigger the “–” status protection mechanism. In the incident on September 11th, exchanges such as Bitget experienced a data flow interruption of 217 seconds due to the outage of AWS nodes, affecting the display of the new ton protocol token price of 560 data platforms worldwide. Third-party monitoring shows that when the API response delay exceeds the 500-millisecond threshold (the normal value is ≤200 milliseconds), the price failure rate increases sharply by 84%. In 2023, a similar failure on Binance caused users to suffer arbitrage losses of over 19 million US dollars.
The core trigger is the drying up of exchange liquidity. When the depth ratio of buy and sell orders becomes unbalanced to above 1:4 (for instance, Bitget’s selling pressure wall is $2.3 million/buying orders are only $800,000), the market maker’s algorithm automatically suspends quotations to avoid risks. On-chain data confirms that the centralized liquidity distribution of the NPT/USDT pool on Uniswap V3 is abnormal, with the proportion of orders placed at the $1.38 price reaching 35% (the healthy value should be less than 15%), similar to the liquidity black hole characteristics before the Celsius incident in 2022. What is even more serious is the cross-chain anchoring failure – the 23 million NPT locked by the Polygon bridge deviates by 4.7% from the balance of the BSC chain, triggering the Chainlink oracle to activate the deviation over-limit protection (threshold 5%).
The security risks of smart contracts directly trigger the pre-cooling process of the exchange. The CertiK audit report shows that the Newton Protocol cross-chain bridge has three high-risk vulnerabilities (CVSS score 8.9), which could put 150 million US dollars in TVL at risk. When the exchange risk control system detects a 300% surge in the frequency of contract exception function calls (such as 127 exception requests per second recorded on September 11th), it automatically freezes the price display. In historical cases, such mechanisms successfully intercepted the transfer of 420 million US dollars in assets during the Multichain vulnerability incident in 2023.
The newton protocol token price anomaly requires a three-stage diagnostic scheme: First, use Etherscan to verify whether the contract 0x8a6 has suspended transactions (when suspended, the gas consumption drops sharply by 98%); The security score of the code detected by the secondary Token Sniffer (currently dropped to 67/100, which is lower than the security threshold of 80); Finally, anchor the on-chain price of the decentralized data source DEXTools (such as $1.35). If the price difference with CEX remains >1.5% for more than 120 minutes, it is confirmed that the price is distorted. In similar incidents in 2023, 85% of the exchanges required the TVL to return to the top 95% of the risk level (currently only 87%) before lifting the quote protection.
