You can purchase EVER on exchanges where it is available and then withdraw them to your EVER Wallet address:

The second way is to transfer your tokens from another network (Ethereum, BNB, Fantom Opera and Polygon) to Everscale using the Octus Bridge cross-chain transfer interface.
At the stage of choosing a token and amount to transfer you can convert a part of sent tokens into a EVER to pay a commission for this transfer and subsequent wallet deployment.
