TRON - "tron.tx.expired" Error

When working with the TRON blockchain, you may encounter the "tron.tx.expired" error, indicating that the transaction has expired and cannot be broadcast after a specific timestamp.

The error occurs when a transaction is not broadcast within the specified expiration time:

• The default TRON transaction expiration time is 60 seconds.
• If the period between transaction creation and broadcast exceeds 60 seconds, the transaction is considered expired.

Example error:

"response": {
    "statusCode": 403,
    "errorCode": "tron.tx.expired",
    "message": "Transaction expired and cannot be broadcast after 1705324314000."
