Txbuilder

Txbuilder helps the user to build the transaction and sign them.

Before building a transaction :

1. Account modular
2. Transaction Model

In Sync, we set a default value for below parameters:

• Expiration(blocks) - 720
• GasPriceCoef - 128
• BlockRef - best Block

Single Transaction

Allow user to transfer VET or VTHO .

VET Transfer

VTHO Transfer

Multi-Transaction

Allows a single transaction to carry out multiple tasks.Since the tasks are contained in a single transaction, their executions can be considered as an atomic operation, meaning that, they either all succeed, or all fail.

Contract Deployment

Deploy a contract on VeChainThor

Once the transaction is sent, Sync will return the txID so that you can query it in Insights, if the transaction is successfully deployed, you can find the contract address in Transaction Receipt
