Hop Protocol Transfer Viewer

WHAT IT DOES

The Hop Protocol Transfer Viewer is a read-only tool that lets you inspect Hop Protocol cross-chain transfers. Enter a source transaction hash and the Hop bridge contract address, and the app fetches the transaction and receipt from the source chain. It then displays the source transaction status, from/to addresses, token symbol and amount, bonder fee, destination chain ID, transfer ID, completion status (sent, completed, etc.), block number, and a count of Hop events found. The tool analyzes transaction logs to detect Hop Protocol's standard events — TransferSent (emitted when a transfer is initiated), TransferFromL1Completed (when a transfer from L1 is completed), TransferSentToL2 (when a transfer is sent to L2), and TransferFromL2Completed (when a transfer from L2 is completed). This gives you a comprehensive view of your Hop transfer lifecycle from initiation through to completion. This is useful for users tracking their Hop transfers, developers debugging cross-chain flows, and auditors verifying Hop Protocol transactions.

HOW TO USE

1. Select your source network from the dropdown or connect your wallet to use its RPC endpoint.

2. Enter the source transaction hash (the transaction on the source chain that initiated the Hop transfer).

3. Enter the Hop bridge contract address on the source chain.

4. Click "View transfer" to fetch and display the transfer details.

5. Review the details: source status, source chain, from/to addresses, token symbol, amount, bonder fee, destination chain, transfer ID, completion status, block number, and count of Hop events found.

6. Use the "Clear" button to reset all fields and start a new view.

ONE TECHNICAL SECTION

This tool uses ethers v5's provider.getTransaction() and provider.getTransactionReceipt() methods to fetch the source transaction and its receipt. It then analyzes the receipt logs to detect Hop Protocol-specific events. The tool looks for the TransferSent event using its signature hash, which is emitted when a transfer is initiated. It also detects TransferFromL1Completed and TransferFromL2Completed events, which indicate that a transfer has been successfully completed on the destination chain. For each event, the tool extracts relevant data such as transfer ID, destination chain ID, amount, and bonder fee. The tool also looks for Transfer events to identify the token being transferred. This event-based approach allows the tool to work with the standard Hop interface across different EVM chains without requiring per-chain configuration.

WHAT IT CANNOT SEE

This tool cannot track Hop Protocol transfers that use private relays or off-chain settlement beyond on-chain events — some Hop transfers may use custom relays or off-chain execution that do not emit standard events. It cannot view transfers that have not been bonded or completed on-chain; if the transfer is still pending or executed off-chain, the tool will only show the initiation events. The tool is limited by RPC availability and event query limits on each chain — if the source chain's RPC does not provide full logs, some data may be missing. It cannot track non-EVM chains, as Hop Protocol primarily operates on EVM-compatible chains. It cannot predict transfer completion times or final settlement delays, which depend on bonder activity and network conditions. It also cannot verify bonder integrity or bridge security without additional Hop Protocol data — the tool shows events but does not validate the bonder's reputation or the bridge's security guarantees.

PLEASE NOTE

This tool works only with EVM-compatible chains that support standard RPC methods and host the Hop bridge contract. The completion status is based on event detection; for full confirmation, check the Hop Protocol interface or the destination chain directly. The tool is read-only and does not sign or send transactions. Always verify Hop Protocol transfer details with official Hop interfaces and multiple sources before relying on this data for financial decisions.
