You can either buy NXTT on MEXC Global or on Uniswap
In order to buy NXTT on a centralised exchange, you need to register to MEXC Global and you can start trading afterwards. You can use this link for registration.
Make sure to have a Polygon-compatible wallet like MetaMask or Trust Wallet.
Also make sure you have either MATIC or another token on the Polygon network in said wallet. You'll need a minimal amount of MATIC to cover the gas fees anyway, so that's what we recommend.
Your MetaMask should look like this:
3. Open Uniswap and change "Ethereum" to "Polygon" in the top right corner.
4. Click "Connect Wallet" in the top right corner and connect your Polygon-compatible wallet.
5. Click "Select a token" and paste the following token address:
6. Enter the amount of MATIC (or your preferred token) that you want to spend on NXTT and click "Swap".
Confirm the transaction in your wallet and you're all set! :)
