\
Users can buy MEV on digital exchanges: [Huobi Global](https://www.huobi.com/en-us/exchange/mev_usdt), [MEXC](https://www.mexc.com/exchange/MEV_USDT), [Coinone](https://coinone.co.kr/exchange/trade/mev/), and [Bithumb](https://www.bithumb.com/trade/order/MEV_KRW).\
\
MEXC is the only exchange that MEVerse mainnet is integrated with at this moment, which means users can transfer MEV directly to Metamask on the MEV network. Otherwise, users must convert the network through the MEVerse account or MEVerse Bridge. MEVerse mainnet will be integrated with other exchanges gradually.\

<mark style="background-color:green;">**How to stake only MEV?**</mark>\
Users can stake MEV by creating a Formulator in the MEVerse account. A Formulator is a mining node of MEVerse.\
\
Anyone who wants to run mining nodes can easily create Formulators and participate in MEVerse token mining. The Formulator has three different types: Alpha, Sigma, and Omega. All the users need to start with Alpha Formulator, a basic level Formulator staking 200,000 MEV.

Alpha Formulators can be upgraded once they face the requirements. After running four Alpha Formulators for a minimum of 30 days, operators can upgrade their Formulators to one Sigma Formulator. Likewise, if Sigma Formulator operators have run two of them at least for 30 days, they can upgrade their Sigma Formulators to one Omega Formulator.\
