An unlikely duo is being sued over participation in an alleged crypto scam.

Kim Kardashian and Floyd Mayweather are facing class-action lawsuits for allegedly misleading investors while endorsing the cryptocurrency coin EthereumMax (EMAX), Reuters reported.

Filed on Jan. 7 in a California federal court, the lawsuit asserts that the reality TV star and the boxer endorsed the tokens sold by EMAX to increase its value.

The lawsuit states: ​​“The Company’s executives, collaborating with several celebrity promotors, (a) made false or misleading statements to investors about EthereumMax through social media advertisements and other promotional activities and (b) disguised their control over EthereumMax and a significant percent of the EMAX Tokens that were available for public trading during the Relevant Period.”

In an Instagram post last year, Kardashian said, “Are you guys into crypto????... This is not financial advice but sharing what my friends just told me about the Ethereum Max token!”

In his boxing match with Logan Paul last year, Mayweather also was involved with promoting the token. EthereumMax was accepted as payment for tickets to the event.

CNBC reports that EMAX has been deprived of 97% of its total value since June 2021. This has given investors cause to believe that the celebrities used false statements to increase the value of the token.

​​"The deceptive narrative associated with the recent allegations is riddled with misinformation about the EthereumMax project," EthereumMax said in response to the allegations, as reported by Reuters. "We dispute the allegations and look forward to the truth coming out."
