There's been a fresh twist in the world of cryptocurrency - Revoke, the platform known for its adept approval management, has initiated measures to outsmart a new, shrewd scam plaguing the crypto space.
The scam involves a clever play with 'gas tokens' and approval revocations, luring unsuspecting crypto holders into a trap that incurs heavy transaction costs. Revoke's response came swiftly following reports of unrecognized approvals appearing in users' transaction history on July 9.
Gas tokens - not the most common household term, but essential in the crypto world - emerged during a spike in Ethereum network fees. Simply put, these tokens allowed crypto users to "store" low-cost gas during periods of lower network activity. Essentially, these users were able to stock up on cheap gas tokens when the network was quiet and utilize them when network fees escalated, a handy method of securing a lower fee.
But the ingenuity of scammers is relentless, turning this once beneficial system into a tool for deception. Fraudsters have been manufacturing counterfeit gas tokens and pairing them with false approvals that users mistakenly believe they must revoke. The underhanded programming of these phony tokens causes an immense generation of gas during the revocation process, while simultaneously sending the freshly minted tokens back to the scammer. The poor victim is then left with a hefty transaction fee.
In response, Revoke has enacted a solution - a new feature that halts approval revocations if an outrageous gas fee is detected. The company also urges users to disregard these bogus approvals, reminding them that Revoke is a tool to ensure safer crypto wallet practices by proficiently managing and revoking active approvals when no longer needed, like those associated with DeFi protocols.
This scam wave comes hot on the heels of a major network exploit that cost multimillion dollars on July 7 and led to platforms like Revoke urging users to revoke approvals for Multichain. As ever, scammers are quick to exploit new vulnerabilities, using this event to trick victims into approving their phony transaction revocations.
