Cross-Chain Bridge
Cropr integrates cross-chain bridging to help you transfer assets between different blockchain networks seamlessly.
Bridge Protocol
Cropr uses the Across Protocol for cross-chain bridging, which provides:
- Fast finality
- Low fees
- High security via optimistic verification
- Wide chain support, including EVM and Solana transfers
Looking to swap into a different token on another chain (not just move the same token)? Use Cross-Chain Swap instead - the Bridge feature transfers a token across chains, while a cross-chain swap also converts it.

How to Bridge
- Go to Bridge from the sidebar
- Select the origin network — The chain you're sending from
- Select the destination network — The chain you're sending to
- Choose the token to bridge
- Enter the amount to transfer
- Set destination address (defaults to your connected wallet)
- Review bridge details:
- Bridge fees
- Estimated time
- Token amounts (source and destination)
- 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.
Across supports bridging between EVM chains and Solana in both directions. EVM and Solana routes use SPL token accounts and Solana addresses on the Solana side, and Cropr builds the appropriate transaction format (an EVM deposit or a Solana versioned transaction) for whichever chain you're sending from.
Bridge Details
Before confirming, you'll see:
| Detail | Description |
|---|---|
| Source Amount | Amount being sent from the origin chain |
| Destination Amount | Amount you'll receive on the destination chain |
| Bridge Fee | Fee charged by the bridge protocol |
| Estimated Time | Expected completion time |
| Route | The bridge route being used |
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.
