How to Exchange ONE to S in 5 Easy Steps

Select the exchange rate
Choose the rate type that works best for you. Pick Floating if you’re okay with market changes, or Fixed if you want to lock in the amount you’ll get. Before you move forward, review the final rate so you know exactly what you’re agreeing to.
Enter your crypto wallet address
Add your S wallet address where you want to receive your coins. Double-check it before continuing, because crypto transactions can’t usually be reversed. Don’t have a Sonic (ex FTM) wallet yet? You can choose one from Changelly’s trusted partners during the process.
Complete the exchange
Follow the payment instructions on-screen and send the exact amount of ONE to the provided wallet address. Make sure you complete the payment within the time limit, since the address may expire.
