Fuel Overview

Fuel is a modular execution layer designed to scale Ethereum by separating transaction execution from consensus and data availability. At its core is the FuelVM, a purpose-built virtual machine that uses a UTXO model and parallel execution to process transactions concurrently across multiple CPU threads.

What distinguishes Fuel is its use of GraphQL instead of traditional JSON-RPC for blockchain interactions, offering more precise and flexible data querying. The platform also introduces Sway, a Rust-based smart contract language designed specifically for the FuelVM.

Interacting with Fuel's APIs

Fuel does not use traditional JSON-RPC methods for blockchain interactions. Instead, it leverages GraphQL, which provides more flexible and precise data querying capabilities. This allows developers to request exactly the data they need in a single query, reducing overhead and improving efficiency.

The Quicknode Fuel documentation is continuously evolving as the chain undergoes upgrades and changes, so we highly recommend cross-referencing with the official Fuel documentation for the latest updates and GraphQL query examples.

Make Fuel API Calls

The quickest way to start building on Fuel is to create a Quicknode endpoint and send your first GraphQL request.

Quicknode provides managed Fuel endpoints, giving you immediate access to Fuel Mainnet and Sepolia Testnet without the overhead of running infrastructure. These endpoints offer:

High reliability – globally distributed infrastructure designed to minimize downtime
Enhanced performance – optimized latency and request handling for production-grade apps
Integrated ecosystem – additional functionality through Quicknode add-ons and products like Streams

Visit the QuickStart page to create your endpoint and send your first request.
