Kim Kardashian has agreed to pay a $1.26m (£1.12m) fine for advertising EthereumMax on her Instagram page.
The US Securities and Exchange Commission said the reality TV star had received $250,000 for advertising the cryptocurrency, without disclosing she had been paid to do so.
She also agreed not to promote crypto asset securities for three years.
Her lawyer said: “Ms Kardashian is pleased to have resolved this matter with the SEC.”
The lawyer said: “Kardashian fully cooperated with the SEC from the very beginning and she remains willing to do whatever she can to assist the SEC in this matter.
“She wanted to get this matter behind her to avoid a protracted dispute.
Kardashian, boxer Floyd Mayweather Jr, basketball player Paul Pierce and EthereumMax’s creators were sued by investors in January.
The legal action alleged they had collaborated to “misleadingly promote and sell” the cryptocurrency in a “pump and dump” scheme designed to inflate the price before selling to investors.
EthereumMax disputed the allegations at the time.
In spite of its name, EthereumMax has no legal or business connection with the Ethereum cryptocurrency.
