| <p>SolidityGuard is an elite <span class="highlight">OpenEnv reinforcement learning environment</span> built for the Meta x PyTorch Hackathon. It trains AI agents to hunt down security vulnerabilities, optimize gas consumption, and enforce coding best practices in Solidity smart contracts.</p> | |
| <p>Think of it as a <span class="highlight">cyber-assassin</span> for your blockchain code. If it compiles, we will break it.</p> | |
