CrossChain Swap User Guide

CrossChain Swap User Guide

CrossChain Swap goes through the following steps.

Step 1) Bridge

The bridge function allows users to interchange an asset on one network with that on another. For example, ETH on the Ethereum network can be bridged to ETH on the BIFROST Network.

Step 2) Swap

The swap function allows users to exchange a certain asset for another asset on the same blockchain. For example, ETH on the BIFROST network can be swapped to BFC on the BIFROST Network.

Swapping to a Token on a Different Network

This guide outlines the swap process with the example of swapping ETH on the Ethereum Network to BFC on the BIFROST Network.

Step 1) Connect Wallet

   The bridge may fail if conditions are not met. (The maximum amount of bridge may change depending on the liquidity condition.)

Step 3) Execute Bridge

2. Check the estimated fee and the token amount to receive after bridging to the selected network. (The fee is subject to change depending on the network.)

3. Click Bridge to execute the bridge.

4. The connected wallet will request to confirm the transaction. Check the estimated gas fee and click Confirm.

(If an alert message such as “We were not able to estimate gas. There might be an error in the contract and this

transaction may fail.” shows, we recommend that you cancel the transaction and retry. If the message reappears, please inquire via the Help Center.)

1. Continue with swap once bridge is complete. The time to transfer is subject to change depending on the network traffic.

2. Open Recommended Swap to find the recommended DEX and the token amount.

Step 5) Check Transactions

You can check the details of your transactions via two methods.

*About Price Impact

In the case the value of the difference between the tokens to send and the tokens to receive is greater than -15% (excluding bridge fee), you will see the following message.

Price Impact Example (excluding bridge fee)

When the difference is less than -15% (message will not be displayed) Price Impact -1% Token A worth $10 > Token B worth $9.9

When greater than -15% Price Impact -15% Token A worth $10 > Token B worth $8.5
