# What is Fuel?

#### What is Fuel?

**Fuel** is a high-performance platform built to make Ethereum Rollups faster, smarter, and more efficient — without compromises.

It brings together cutting-edge technology to solve key challenges like scalability, execution speed, and developer experience.

***

#### FuelVM — A Smarter Virtual Machine

Fuel uses its own virtual machine — **FuelVM**, which is much more powerful than the standard Ethereum Virtual Machine (EVM).

FuelVM allows transactions to run **in parallel**, thanks to its use of a **UTXO model**. That means it can process many transactions at once by knowing exactly which data each one will touch — making full use of modern CPUs and delivering much higher performance.

***

#### Sway — A Language Built for Blockchain

Fuel also includes a purpose-built programming language called **Sway**, designed specifically for writing smart contracts on Fuel.

Sway combines the best of **Rust** (safety, performance) and **Solidity** (smart contract patterns), giving developers a powerful and elegant way to build Web3 apps.

With Sway, you get:

* Rust-like syntax and compile-time safety
* Built-in features for blockchain development
* An ecosystem of examples, libraries, and standards

***

#### Developer Tooling

Fuel isn’t just a VM and a language — it’s a full **developer stack**. From the CLI to the compiler, everything is tightly integrated, offering a seamless experience for building next-gen decentralized applications.

***

Fuel is the next evolution of Ethereum Rollups — bringing speed, safety, and power to both users and developers.
