Sway Audit
Specialized security audits for Sway smart contracts on Fuel Network. Our experts understand the unique architecture and security considerations of Fuel's modular execution layer.
What is Sway?
Sway is a domain-specific language (DSL) for the Fuel Network, designed to leverage the advantages of both Solidity and Rust. It provides memory safety, performance optimization, and expressive syntax for building secure smart contracts.
Fuel Network Integration
Native support for Fuel's UTXO-based architecture and parallel execution
Memory Safety
Rust-inspired ownership model preventing common memory vulnerabilities
Performance Optimization
Compiled to FuelVM bytecode for efficient execution
Sway Language Features
Sway-Specific Security Considerations
Asset Management
Fuel's native multi-asset support requires careful validation of asset transfers and balance tracking.
- • Asset ID validation
- • Balance overflow protection
- • Transfer authorization
UTXO Model Security
Fuel's UTXO-based architecture introduces unique security patterns different from account-based models.
- • Input validation
- • Output construction
- • State transition verification
Predicate Logic
Predicates control spending conditions and require thorough validation to prevent unauthorized access.
- • Condition verification
- • Logic completeness
- • Edge case handling
