A clumsy trader claims he “ruined” his life after he inadvertently paid $ 9,500 in transaction fees of $ 120 on the Uniswap Decentralized Exchange (DEX).

On November 5, Reddit user ProudBitcoiner reported that he mistakenly paid 23.5172 Ether (ETH) per trade after the Gas Limit and Gas Price fields in his MetaMask wallet became confused.

“Metamask did not fill the gas limit field with the correct amount in my previous transaction, and this transaction failed, so I decided to change it manually in the next transaction […] But instead of entering 200,000 in the gas limit” the input field, I wrote it in the fuel field, so I paid 200,000 GWEI Against this treatment it ruined my life. ”
Uniswap is an ERC-20 token exchange with no escort, which means that the deals are made directly from the user’s wallet, so they can manually enter the gasoline prices they wish to pay for each transaction.

The user noted that he recently downloaded MetaMask version 8.1.2 and had previously had no problems filling the gas limit field.

Redditor Mcgillby suggested that MetaMask introduce security measures to force users to confirm a transaction when the declared gas price exceeds the estimated price calculated by the wallet significantly:

“You think they’ll have some kind of warning, like” I’ve exceeded the amount required for inclusion in the next batch by a large amount, “and it will force you to confirm. Metamask actually calculates the recommended gasoline price automatically, so I don’t see any reason why they shouldn’t get more confirmation if Someone exceeded the recommended gasoline price by a huge margin.
In June, Cointelegraph reported two mysterious transactions, each spending $ 2.6 million to convert about $ 130 off Ether. Analysts have provided various explanations for the transactions, including a possible mistake in a money laundering fine, retaliation against a former employee, or simple human error.
