How to Exchange OP to ARB in 5 Easy Steps
Set up your exchange
To exchange OP to ARB, use the calculator at the top of the page to start your swap. Choose OP in the “You send” field and ARB in the “You get” field, then enter the amount you want to exchange. You’ll see how much Arbitrum you are expected to receive after the swap.
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 ARB 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 Arbitrum 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 OP to the provided wallet address. Make sure you complete the payment within the time limit, since the address may expire.
Check your crypto wallet
Once your swap is processed, your ARB will be sent straight to your wallet. After that, you’re all set. There are no extra steps needed.
