Sway Audits
Looking for top-tier Sway audits? At Linum Labs, we are industry leaders in auditing smart contracts written in Sway, the cutting-edge programming language for the Fuel blockchain. Our team of expert auditors is proficient in Sway's unique syntax and Fuel's UTXO-based architecture, enabling us to identify vulnerabilities, optimize performance, and enhance the security of your smart contracts.
We provide comprehensive Sway smart contract audits for DeFi protocols, dApps, and custom blockchain solutions, ensuring your contracts are secure, efficient, and ready for deployment. With a proven process and meticulous attention to detail, we help you deploy Sway-based projects with confidence. Partner with us for reliable, in-depth Sway audits and protect your blockchain applications against threats.
Analysis of Fuel’s UTXO model
Unlike traditional account-based systems, Fuel’s unique UTXO architecture demands precise handling of inputs, outputs, and transaction validation. Our team leverages this deep knowledge to identify vulnerabilities, prevent misuse of state transitions, and optimize performance. By aligning your Sway smart contracts with the design principles of the Fuel blockchain, we ensure security, efficiency, and seamless execution.
Asset Management With Predicates
Fuel’s predicates enable secure, lightweight asset management without deploying full smart contracts. At Linum, we rigorously audit predicates to ensure correctness, prevent bypass vulnerabilities, and validate logical conditions for asset transfers. Our expertise guarantees that your predicates are secure, efficient, and fully aligned with Fuel’s stateless design principles.
Parallel Transaction Execution
Fuel's parallel transaction execution introduces immense scalability but requires strict transaction independence to avoid state conflicts. We audit your Sway smart contracts to identify race conditions, ensure deterministic behavior, and optimize state transitions. By leveraging our deep understanding of Fuel's execution model, we secure your contracts for high-throughput environments while maintaining performance and reliability.
FuelVM
The FuelVM powers the Fuel blockchain with its optimized execution environment, but improper handling of state transitions, resource accounting, or opcode usage can introduce critical vulnerabilities. We audit your Sway smart contracts to identify issues such as inefficient gas usage, unintended state mutations, or invalid opcode implementations. By ensuring precise execution logic and adherence to FuelVM’s deterministic requirements, we help you avoid unexpected behavior, reduce costs, and deploy secure, optimized contracts.
Our Process
The audit process plays a crucial role in enhancing security and establishing a solid foundation for decentralized solutions. Each step is carefully designed to protect and improve the integrity of your blockchain applications.
