A sleeping Cardano whale tried to swap 14.4 million ADA for USDA and walked away with just 847,000 USDA, burning through approximately $6.2 million in a single click.
A long-dormant Cardano (ADA) whale torched more than $6 million in a single trade after attempting to move 14.4 million ADA, worth around $7 million, to USDA, a Cardano-native stablecoin, in a low-liquidity pool.
The transaction left the wallet with just 847,000 USDA, an estimated loss of 87%, and reopened difficult questions about Cardano’s readiness for DeFi.
The expensive transaction
According to on-chain investigator ZachXBT, the whale wallet had been inactive for around five years before executing the swap, which temporarily pushed the USDA price well above its peg due to low liquidity.
Lookonchain reported the transaction at 14.45 million ADA, with a valuation just north of $7 million, resulting in the user receiving 847,694 USDA and taking a loss of approximately $6.2 million.
Screenshots shared by community member $DeFiPunk show the DEX interface displaying a “high price impact” warning and slippage estimated at over 87%, with the user manually checking the “I understand this warning” box before confirming the transaction.
This sparked a debate over whether this was a reckless move, an honest mistake by an “inexperienced voucher holder,” as Cardano founder Charles Hoskinson suggested, or even a deliberate attention game to highlight liquidity issues.
Reactions from the Cardano community have been mixed. Some, like Cardano YOD₳, have argued that “a bad exchange can have negative reputational consequences” and questioned whether the ecosystem has the right priorities, pointing to marketing and governance debates over basic liquidity.

Others countered that the problem was primarily “a liquidity problem first, and a DEX problem second,” criticizing the slow delivery of UX upgrades and the need for better batching solutions.

Market pressure and ecosystem requirements
The multimillion-dollar mistake marks a continuing period of pressure for Cardano, with on-chain data from earlier this month showing whales offloaded 4 million ADA in a week as prices fell from above $0.60 to around $0.53, further reinforcing bearish sentiment.
A few days later, on November 11, there was further accumulation, with other large holders grabbing almost 1% of the supply during a drop below $0.50, leading analysts to predict a possible rebound if ADA managed to reclaim the $0.70 area. That hasn’t happened yet, with the asset, ranked eleventh in terms of market capitalization, trading around $0.50, down about 17% in the past week and 22% over the past 30 days, according to CoinGecko data.
Meanwhile, the episode intensified calls for greater stable liquidity on Cardano. Commentator Lorenzo clearly argued: “We need to increase the withdrawal of stable liquidity by 10 now. This sentiment has been echoed by others who believe the incident proves that there is substantial demand for capital transfer on the network, but a lack of infrastructure to support it. However, Hoskinson has repeatedly asserted, “It’s not my job to bring a stablecoin to Cardano,” placing the onus on the ecosystem as a whole.
