What is Fuel?

Introduction to the Fuel Network

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.
