A user of the 1inch aggregator gave $83,000 for tokens worth $100

The user of the aggregator of decentralized exchanges 1inch Exchange gave $83,000 in USDT, but received in return tokens worth only $100.

According to the transaction history in the blockchain, the user sends 83,298 USDT to the address of the 1inch router to purchase the Digg token. Subsequently, its USDT is exchanged for Wrapped Ether (WETH) via the 0x Protocol at a fair rate, which is then sent by 1inch to the SushiSwap exchange to purchase the Digg token from the pool, which at that time had about $200 of liquidity. As a result, the payout was only 0.001961307 DIGG worth $116.

The affected user was a trader from China, who told about the incident on social networks and asked for help. The developers responded to the incident, stating that the application engine in this case worked correctly. Presumably, the user himself agreed to such terms of the transaction, despite the warning of the platform. In the 1inch interface, a warning does appear if the rate at the conclusion of the transaction will be very different from the market due to a lack of liquidity, but the user insists that according to the displayed information, he should have received 1.59 DIGG.

"1inch Foundation will reimburse the user for his error," the developers wrote. – We will add an additional (third) major warning and restriction to avoid such cases. Pathfinder gives you the right course, just like it did before!»

We also managed to find a second participant in the transaction, who sold tokens for $100 for $83,000. It turned out to be a mining pool that uses an arbitrage bot to increase its earnings. This is indicated by the transaction processing fee of 1 wei, which would have no chance of confirmation if it had not been sent and processed by the pool itself.
