Buying SNT tokens works the same way as buying other ERC-20 tokens, such as DAI or UNI.
You can buy SNT with fiat currencies (such as USD, EUR and others) using Status Wallet. You need some Ethereum (ETH) to cover the transaction fees (also known as gas fees). For information on how to buy SNT in the Status app, see Buy crypto.
In addition to Status Wallet, you can buy SNT tokens from third-party exchanges. For the up-to-date list of exchanges you can currently buy SNT from, see the Status website. On these exchanges, you can buy SNT with both fiat currencies or other crypto assets.
