How to Bridge

  1. Go to Bridge from the sidebar
  2. Select the origin network — The chain you're sending from
  3. Select the destination network — The chain you're sending to
  4. Choose the token to bridge
  5. Enter the amount to transfer
  6. Set destination address (defaults to your connected wallet)
  7. Review bridge details:
    • Bridge fees
    • Estimated time
    • Token amounts (source and destination)
  8. Confirm the bridge transaction in your wallet

Your connected wallet's network must match the origin chain. Cropr will prompt you to switch networks if needed.

Bridge Limits

Each bridge route has minimum and maximum transfer limits that depend on:

  • The token being bridged
  • Available liquidity on both chains
  • Protocol-specific limits

Cropr automatically fetches and displays these limits before you confirm a transaction.

Transaction Tracking

Bridge transactions are recorded with full details:

  • Source chain, token, and amount
  • Destination chain, token, and amount
  • Transaction hash on the source chain
  • Timestamp

You can view all bridge transactions in the Transactions page.
