Trader crypt loses more than USD $ 500,000 for Chainlink oracle failure

The operation occurred at the rate of the price differential between the stablecoin Deusd and USDT, attributable to the oracle of Chainlink used in Curve What happened puts on the table the risks of these in little liquid markets and in the sector DEFI.

***

• A series of operations in the pool of Curve briefly manipulated the price of token Deusd
  
• This caused an automated settlement on the loan platform Euler
  
• Chainlink He defended his price system while criticisms of the oracles intensify.
• However, it seems that oracles can be vulnerable in little liquid markets.

An incident in the ecosystem DEFI unleashed the loss of more than USD $ 500,000 for a trader, after an alteration in the price of Token Deusd will cause its liquidation on the loan platform Euler

According to a report published by The Blockapparently everything happened as a result of an unusual activity in the pool of Curve, So the unfortunate event has revived criticisms of oracles such as Chainlink, for its supposed vulnerability in markets with low liquidity.

What happened to the price of deusd?

The situation originated on Thursday with a series of large operations in the pool of Curve That matches Deusd with USDT The first is a synthetic stablecoin issued by Elixir Networkwhich usually maintains parity with the US dollar, while the second is the currency of its type with the greatest adoption at the international level ..

According to Zach Rynes, defender of Chainlink known as “Chainlink God “a key operation involved the bot Mev Jaredfromsubway, who exchanged USD $ 210,000 in USDT By USD $ 202,000 in Deusd This action and similar ones carried the price of Deusd about USD $ 1.03.

Since the oracle of Chainlink Use a system of Average price weighted by volume (VWAP), The information transmitted to the protocols reflected the inflated price, which eventually activated trader settlement on the platform Euler, displayed on Avalanche

The incident revived the questions about the oracles in Blockchain, which are systems in charge of feeding price data to decentralized applications. Several developers argued that these can be manipulable in low volume markets.

Omer Goldberg, founder of Chaos Labs, said in X that “Chainlink has just demonstrated that oracles are one of the weakest links in Defi.” For its part, a spokesman for Pyth, identified as “Pepito”, also suggested that the oracle of Chainlink It could have been manipulated.

Chainlink He responded by stating that his system worked as he was designed. Rynes explained that the VWAP It was correctly calculated based on the available data, although he acknowledged that the market in question was volatile and lacked sufficient liquidity.

High risk and necessary precautions

Rynes himself indicated in X that the asset Deusd was categorized as “High market risk” by its low volume and limited liquidity. He also warned that the protocols that make up these assets must take additional caution measures.

The total supply of Deusd It is approximately USD $ 185 million, with USD $ 42.7 million in the network Avalanche, which accentuates its exposure to manipulations in narrow markets.

Goldberg proposed that Chainlink Adopt more robust methods to establish stablecoins prices, such as limiting the maximum price or applying less vulnerable algorithms to atypical values.

“Using VWAP in Illicid pools is an exploitable design”Said Goldberg. “You are pondering volume in pools with little liquidity. Of course, a single large operation will move the price.”

Chainlink It is the largest oracle supplier of the blockchain ecosystem, ensuring almost USD $ 45,000 million in assets along about 20 networks. What happened puts the limits of its technology in the focus when it faces the poor market depth scenarios.

This event also serves as a reminder for developers and users about inherent risks when operating in Defi, especially with less known assets or pools with low volume. The confidence in the oracles, the cornerstone of many protocols, could be eroded if its mechanisms do not adjust to high volatility contexts.
