It does not differ anyhow from trading cryptocurrencies:
- Open the “Exchange” screen
- Choose the assets you want to trade (i.e. ZARs -> USDs) and enter the desired amount of USDs to buy
- SOL wallet will show you the live rate, full cost in ZARs and the transaction fees (if any)
- Confirm the transaction by your PIN or a fingerprint
Exchange happens instantly, and you see your updated account balances immediately.
Note that SOL does not execute foreign currency exchange directly. USDs, EURs, NGNs etc are cryptocurrencies issued by SOL Wallet and backed by SOL funds in the same currencies, allowing you to trade those tokens at the interbank FX rates - instantly and without any hidden fees.
