Hi everyone, Raoul from Chainlink Labs here. We’d like to provide some clarification and corrections to the statements made by Chaos Labs regarding an alleged price deviation with Chainlink Data Feeds.
Chainlink Price Oracle Performance
Based on our in-depth analysis into the performance of the Chainlink CAKE/USD price feed on BNB Chain on the 10th of October from 21:00 to 22:00 UTC, we found that the feed accurately tracked the pricing of CAKE reported by centralized exchanges where the higher trading volumes occurred (CEXs equated to approximately 73% of the trading volume). Most notably, the Chainlink feed closely tracked the CAKE/USDT Binance trading pair, which is the most highly traded market for CAKE.
Chainlink Data Feeds, including the CAKE/USD feed, use a volume-weighted average price (VWAP) methodology, where exchanges with greater trading activity have a larger influence on the final aggregated price than exchanges with less volume. This pricing methodology has been proven to successfully protect against pricing anomalies by reporting the market-wide, volume-weighted pricing of an asset based on real executed trades, while filtering out outliers on lower-volume markets.

To summarize the chart above, during the extremely high volume of trading activity, the price of CAKE dropped significantly, especially on Binance, which was accurately reflected by the Chainlink CAKE/USD price feed on BNB Chain. With Binance falling as low as $1.51 and Chainlink $1.55. The chart showcases prices for CAKE across major venues (Binance, Bitget, Bybit, Coinbase, Gate.io, HTX, Kraken, and Kucoin) and how Chainlink’s VWAP aggregated pricing methodology performed with high levels of accuracy, even during the most extreme market conditions.
Therefore, while some smaller onchain venues may have temporarily seen different pricing than Binance for CAKE, the Chainlink feed accurately tracked the markets with the highest volume.
Liquidation Delays in Searcher Market
The aggregate position opened by 0xa98e339f5a0f135792286d481b4e23d91a667d3f became unhealthy at 21:22:44 UTC at block 64175883 with a total of $27,000 value below its Health Factor. Liquidations of this position were available to searchers on BNB Chain from this block.
The first liquidation transaction did not occur for 4 minutes and 49 seconds, after the Chainlink CAKE/USD oracle had updated 24 times from $1.58 to $1.95. There was a time period of 30 seconds where the price on the Chainlink price feed reflected a price higher than that of the PancakeSwap CAKE pool. This indicates the searchers on Venus were not active as this would have been an atomic and profitable liquidation. This indicates that although this position was available to be liquidated safely, by leveraging the prices on Binance and repaying the loans on Venus, this did not occur.
This issue could be addressed by expanding and optimizing the Venus searcher network. Chainlink has established relationships with a large variety of the top searchers through our work on SVR price feeds and we would be happy to work with the Venus community to help improve searcher diversity on Venus markets by including market makers and other entities who are active on CEXes and hold liquidity on their own books.
Role of Price Oracle vs Risk Configuration
The Chainlink CAKE/USD price on BNB Chain closely tracked the price of CAKE on the most active trading venues, most notably closely following the CAKE/USDT market on Binance.
The analysis conducted by Chaos Labs focused solely on pricing from a single on-chain market for CAKE, without accounting for pricing from major active markets such as Binance, representing a significant oversight in the evaluation. Proper risk management includes taking into account situations of price dislocation where onchain markets may not reflect the same pricing seen within centralized exchanges like Binance where a higher proportion of trading activity occurs. It’s possible that this issue could have been avoided if risk parameters were configured properly to take into account these risks.
