Tx-Validation

Send transaction and simultaneously ensure they are valid

Transactions are added to a block only if they pass the node's validation test.

Use the Tx Validation utility to send transactions while, at the same time, ensure that you are constructing your transactions correctly, i.e. that they will pass the test.

Send the transaction using the request format below. The response will include:

1. Your request in the format that should be used when sending it to CloudAPI

2. Details about the transaction such as gas price and value

3. If an error occurred, information about the error

Tx Validation adds a layer of usability to the existing node validation utility.

When adding node_validation: true to a transaction request you will receive an error response only if your transaction was not valid.

Using Tx Validation you will always get a response and additional information is provided regarding errors, if and when they occur.
