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.

Fuel’s predicates enable secure, lightweight asset management without deploying full smart contracts. At Audit Labs, 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.

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.

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.
