A crypto bridge moves tokens from one blockchain to another. With Step Exchange you pick from and to in the widget above; the route can use a bridge alone, or combine a swap and a bridge so you receive a different token on the destination network. Every transaction is signed in your own wallet, and the total cost, including gas, bridge fees and our 0.7% service fee, is shown before you confirm.
How a Bridge Transfer Works
- Choose the route: source network and token, destination network and token.
- Compare: the widget shows the routes found, with amount received and time.
- Approve and sign on the source network.
- Receive on the destination network; add the network to your wallet if needed.
