# Transactions

## What is a transaction in VeChain?

A transaction, similar to any blockchain network, refers to an action or event that involves the transfer or modification of data within the blockchain.

By executing a transaction a blockchain can: transfer a digital token from one address to another; deploy a smart contract on the blockchain or trigger the execution of a smart contract.
