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.
