Hardware Security Module Integration Test Tool

WHAT IT DOES

This tool tests Hardware Security Module (HSM) integration readiness by analyzing on-chain contract patterns and security properties. It performs a comprehensive suite of read-only checks against a target contract to verify that it correctly implements signature verification compatible with HSM-generated signatures and includes appropriate hardware security features. The tool checks for contract deployment verification, wallet connectivity, HSM-compatible signing patterns (secp256k1), ecrecover implementation, signature validation logic, hardware security features, replay protection, key rotation support, attestation support, and secure audit trails. Results are presented as a detailed test report with pass/fail/warn statuses for each test, along with HSM-type-specific recommendations. This is essential for teams implementing HSM-based signing for administrative functions, multi-sig wallets, or automated contract interactions requiring hardware-level key security.

HOW TO USE

Connect your wallet (read-only, no transaction required) and select the target network. Enter the contract name and address that implements HSM-compatible signature verification, select your HSM type (AWS CloudHSM, Azure Key Vault, GCP Cloud KMS, Ledger, YubiKey, or Custom), and set the lookback blocks for log analysis. Click "test HSM integration" and the tool will verify the contract, analyze its bytecode and ABI for HSM-compatible patterns, check wallet connectivity, and run a comprehensive test suite tailored to your HSM type. Results display a summary with pass/fail/warn counts and an overall status, detailed test cards showing each test's outcome with supporting data, and a table of all tests. Use the report to identify integration gaps, verify HSM compatibility, and ensure your contract's security properties align with hardware-level key management requirements.

TECHNICAL MECHANISM

The analyzer uses ethers.js v5.7.2 to perform a multi-stage HSM integration test. First, it calls eth_getCode to verify the contract is deployed and uses block explorer APIs to fetch verification status and source code. The tool then reads the current wallet state via BGWallet, capturing the connected address and chain ID for context. It analyzes the contract bytecode and ABI to detect HSM-compatible patterns—specifically looking for ecrecover opcode usage, keccak256 hashing patterns, standard signature validation flows, key rotation mechanisms (mapping of authorized signers), and attestation verification patterns. The tool also scans historical logs using eth_getLogs across the specified block range to identify signature verification events, key rotation events, and audit trails. Each test in the suite evaluates a specific aspect of HSM integration: contract deployment, wallet connectivity, HSM-compatible signing (curve detection), ecrecover implementation, signature validation logic, hardware security features (secure storage patterns), replay protection (nonce, chainId, deadline checks), key rotation support (authorized signer mappings), attestation support, and secure audit trail (event emissions). Results are compiled into a structured report with detailed diagnostic information and HSM-type-specific recommendations.

WHAT IT CANNOT SEE

This tool cannot actually test HSM hardware or key generation functionality—it performs analysis and verification only. It cannot access actual HSM keys, encrypted data, or physical hardware devices. The tool is limited by the RPC provider's rate limits and block range availability for historical log queries. It cannot verify signatures that are not on-chain or have been generated outside the analyzed scope. The analysis relies on the accuracy and completeness of contract verification and signature data; unverified contracts or incomplete ABIs may produce incomplete results. It cannot analyze contracts that are not verified or have opaque implementation details where signature verification is obfuscated. The tool cannot test HSM integration with off-chain systems or external signing devices beyond the contract's on-chain logic. It is limited to the specific contract instances and signatures that are accessible via RPC. It cannot detect hardware-specific edge cases, performance characteristics, or physical security properties. It cannot guarantee that security properties match actual HSM implementation without manual review and physical hardware testing.

PLEASE NOTE

This is a read‑only analytics tool—it never submits transactions or signs anything. It is designed for EVM‑compatible chains and works best with contracts that implement HSM-compatible signature verification patterns. The test results are for informational and audit purposes only and should not be considered a comprehensive security audit. Always manually review signature verification logic and perform actual HSM integration tests with hardware devices before deploying to production. The tool's pattern detection is heuristic and may miss custom implementations or HSM-specific features.
