# Smart Contracts on Tron Network - What Are They and How Do They Work?

The TRON network has quickly transformed from being a simple content sharing destination into a thriving ecosystem where DeFi, gaming, and all sorts of other complex applications now reside.

The TRON network has quickly transformed from being a simple content sharing destination into a thriving ecosystem where DeFi, gaming, and all sorts of other complex applications now reside. At the center of this tidal wave is a potent technology: smart contracts.

## Digital Vending Machine: What Is a Smart Contract?

Before we go into the details of TRON, allow us to give you a crude analogy. Imagine a smart contract as a super complex digital vending machine. A transaction's rules are coded right into it.

- Immutable: Once deployed on the blockchain it cannot be changed
- Transparent: Code is open in the blockchain for anyone to view
- Decentralized: Does not depend on a single central authority

## The TRON Virtual Machine (TVM): Main Engine in the System

The TRON Virtual Machine (TVM) is a Turing complete virtual machine with a simple and lightweight design for carrying out smart contract's logic quickly and safely.

## USDT on TRON: TRC-20 Smart Contract Explained

**How USDT transfer works:**

1. Create Transaction: You perform transfer from your wallet
2. Network Broadcast: The transaction is broadcast to the network
3. Smart Contract Execution: The TVM executes the transfer() function

Smart contracts have an ongoing and expanding purpose on the TRON network. They are reinventing finance, gaming and digital ownership by replacing the centralised intermediates with transparent, automated and unstoppable code.
