Operation Overview

Steps to bridge a token

To perform a cross-chain token transfer using Airlift, you'll need to provide the following information:

• Token address on the source chain

• Source Chain ID

• Destination Chain ID

• Amount to transfer

Once you have this information, just follow these steps:

1. Check supported routes

Send a request to the /routes API endpoint to determine if the desired route is supported. The response includes route metadata such as estimated duration and gas costs, powered by the indexer.

2. Get a quote

Use the /quote API endpoint to retrieve the fees required to execute the transfer.

3. Initiate the transfer

Call the send function on the Airlift smart contract using the data returned by the quote. This triggers the cross-chain transfer through the appropriate token implementation and returns a transaction hash on the source chain.

4. Track the transfer

Periodically query the /transaction API endpoint to monitor the status of the cross-chain operation with the TX hash returned in the send operation.

5. Receive funds on the destination chain

Once the operation status is marked as DONE, the tokens will be available on the destination chain.
