}TRON API method that broadcasts a transaction to the TRON network using hexadecimal format. This method allows you to submit pre-signed transactions directly to the blockchain without needing to use the standard JSON transaction format.
Get your own node endpoint todayStart for free and get your app to production levels immediately. No credit card required.You can sign up with your GitHub, X, Google, or Microsoft account.
Parameters
transaction— the complete transaction data encoded in hexadecimal format, including all signatures and necessary fields
Response
result— boolean indicating whether the broadcast was successfultxid— the transaction hash if the broadcast was successfulmessage— descriptive message about the broadcast status
Use case
Thewallet/broadcasthex method is used for:
- Broadcasting pre-signed transactions in hex format to the TRON network.
- Submitting transactions that were created and signed offline for security purposes.
- Integrating with external signing tools and hardware wallets that output hex-encoded transactions.
- Building custom transaction broadcasting workflows that require hex format compatibility.
- Supporting legacy systems or tools that work with hexadecimal transaction data.
curl example
The example below uses a syntactically valid transaction hex, so the node parses it and returns a JSON result. Because the signature is a placeholder, you should expect a logical error (for example,SIGERROR) rather than a parsing exception. Replace the transaction value with the full hex of a transaction you have actually signed to get result: true.
