TestMachine offers a continuous security platform for Web3 protocols that dynamically analyzes smart contracts by forking blockchain state and running reinforcement‑learning agents to simulate real transaction attacks. The system generates and validates exploit proofs, scores severity, and provides remediation guidance across major EVM‑compatible chains, ensuring ongoing protection against upgrade‑related and economic vulnerabilities.

Problem
Static code audits for smart contracts often miss vulnerabilities that emerge from contract upgrades, complex economic interactions, and evolving attacker tactics, leading to costly exploits and rug pulls even in audited projects.
Solution
TestMachine provides a dynamic security platform for Web3 protocols that continuously analyzes smart contracts by forking blockchain state and deploying reinforcement‑learning agents to execute real transaction scenarios. The system first ingests code, ABIs, on‑chain state and economic parameters, then uses large language models to map attack surfaces and economic flows. Generated hypotheses are tested by RL agents in a sandboxed fork, which aim to maximize token extraction. When an exploit path is found, the platform automatically creates a reproducible proof‑of‑concept, assigns a severity score, and suggests remediation, ensuring zero false positives. Continuous re‑testing adapts to contract upgrades and market changes, covering all major EVM‑compatible chains.
Target Audience
Primary customers are DeFi protocols, crypto exchanges, and blockchain projects that require continuous, automated security assurance for their smart contracts and token listings.
