Yes, Meta (formerly Facebook) has a cryptocurrency called Diem (formerly Libra). The project was announced in 2019 and is designed to be a stablecoin that is pegged to a basket of fiat currencies, making it less volatile than other cryptocurrencies like Bitcoin.
Diem is intended to be used for digital payments and transactions within the Meta ecosystem, such as in the Facebook Marketplace or in WhatsApp. It is also designed to provide financial services to people who don't have access to traditional banking services.
The project has faced regulatory scrutiny and criticism from governments and financial institutions around the world. In response, the Diem Association, which oversees the project, has made several changes to the original plan, including moving its operations to the United States and shifting its focus to compliance and regulatory requirements.
As of February 2023, Diem has not yet been launched, and its exact release date is still uncertain.
