List of Blockchain Development Security Tools companies in Web3 (2026)

MPC Enterprise Key Management is an enterprise-grade key management solution using multi-party computation technology. It provides secure cryptographic key generation, storage, and signing operations for organizations requiring institutional-level security controls for digital asset management.

Immunefi Safe Harbor Integration provides automated whitehat rescue coordination through Security Alliance's legal framework, enabling protocol-controlled fund recovery during active exploits. The system routes rescued assets to protocol-designated Vaults via existing bug bounty infrastructure while managing researcher compensation and legal compliance. The service combines disclosure dashboards, emergency alerting, and vault management to facilitate coordinated security responses with predetermined reward structures.

Turnkey Verifiable Cloud is a platform that lets developers run arbitrary application code inside isolated, verifiable secure enclaves powered by trusted execution infrastructure. It packages custom workloads as container images that are deployed and cryptographically verified before execution, removing the need for developers to manage their own enclave operating environment. Teams building sensitive or security-critical workloads use it to run verifiable applications with autoscaling and high-availability deployment across multiple replicas.

AuditAgent is a smart contract security tool that identifies vulnerabilities using AI and static analysis. It generates reports and suggests fixes for code issues.

Clear is a formal verification framework for Solidity smart contracts that translates Yul programs into the Lean proof assistant for computer-checkable correctness proofs. It enables developers to mathematically prove contract behavior against formal specifications.

Multisig Inspector is a free, read-only tool for reviewing Safe multisig wallets before a transaction is signed. It reads owner lists, signer thresholds, active modules, guards, and the fallback handler directly from the blockchain, and decodes pending transactions to recompute their transaction hash for comparison against a hardware wallet display. Protocol teams and security researchers use it to verify multisig configuration and transaction intent without connecting a wallet or exposing any keys.

QuillGuard is a security layer for autonomous AI agents that detects vulnerabilities across known attack surfaces and applies behavioral guardrails. It wraps an agent's underlying model to screen incoming prompts for jailbreak attempts and to block outputs that violate defined policies, such as unauthorized financial actions. The guardrails are tailored to an agent's specific logic and update as new attack patterns are identified, and the product is used by developers building agents that execute on-chain actions.

QuillShield is a scanning tool that detects vulnerabilities in smart contract code before a formal audit is performed. It analyzes contract logic for edge cases and known flaw patterns using automated, AI-assisted detection, and can be run continuously as code changes during development. Developers use it to identify issues early and to start the formal audit process from a cleaner code baseline.

SolidityScan is a cloud-based smart contract vulnerability scanner that uses static analysis and AI-assisted detection across source code, repositories, and on-chain contracts. It processes inputs through detectors aligned with the OWASP Smart Contract Weakness Enumeration, generating security scores and audit reports with remediation guidance. The platform integrates with GitHub, GitLab, BitBucket, VS Code, and Remix IDE, with scanning also accessible via a REST API and SDK.

MoveScanner is a static analysis tool that converts Move bytecode to intermediate representation and control flow graphs to detect vulnerabilities in Move smart contracts.

Glider provides query-based smart contract analysis for EVM blockchains, enabling security researchers to scan entire chains and identify vulnerabilities in under 30 seconds through advanced static analysis.

Certora Prover performs formal verification of smart contracts by analyzing bytecode against rules. The system decompiles blockchain code to intermediate representation, applies static analysis, generates verification conditions, and uses solvers to detect rule violations. It supports EVM, Solana, and Stellar through a unified workflow.

Certora Gambit identifies weaknesses in smart contract specifications by generating mutations of code to test formal verification coverage. The tool injects code variants with intentional bugs, testing the effectiveness of verification rules in catching vulnerabilities. It categorizes mutations to help developers focus on critical areas and improve security specifications.

Orbit Core is a security protocol for Solana wallets that prevents drainer attacks through pre-connect canary probes, plain-language transaction rendering, and adaptive risk scoring. The system tests websites before wallet handshakes, translates raw blockchain instructions into human-readable intent, and escalates intervention from warnings to biometric re-authentication to hard blocks when suspicious patterns emerge. Orbit Core operates as an invisible security layer integrated directly into wallet infrastructure.

AI Security Scan is an AI-powered vulnerability analysis tool that examines smart contract code for early-stage security signals. It extracts function-level call graphs from Solidity codebases and returns candidate findings, such as accounting desynchronization risks or oracle validation issues, for expert validation. The tool is available as a hosted web application and as an open-source local command-line tool that developers can run against their own repositories. It is positioned as a preliminary analysis aid rather than a substitute for a full manual audit.

KannAudits is a smart contract security audit service that reviews Web3 protocols for vulnerabilities before and after deployment. Human reviewers perform manual code review and architecture analysis across codebases written in multiple smart contract languages, covering business logic, integrations, and risk profile. The service also offers formal verification of critical protocol properties and emergency incident response for suspected exploits or critical vulnerabilities. Engagements produce detailed audit reports documenting findings across decentralized finance protocols, blockchain networks, and infrastructure projects.

A security scanner designed for Solana smart contracts, detecting over 50 types of vulnerabilities.

Riverguard automates vulnerability detection in Solana smart contracts through transaction simulation and mutation testing. The system ingests live Solana transactions, applies mutation rules to test for exploitable bugs, and reports findings to contract developers. Riverguard operates continuously on Solana mainnet, analyzing millions of transactions to identify common vulnerability patterns including loss of funds and denial of service issues.

Trail of Bits develops and maintains open-source security tools for blockchain developers, including Slither (static analyzer), Echidna and Medusa (smart contract fuzzers), and other utility libraries for enhancing blockchain security.

SEAL 911 provides emergency incident response services for blockchain security threats through a dedicated Telegram bot connecting users with expert security researchers for real-time assistance during active exploits and cyber attacks.

Safe Harbor is an on-chain legal agreement framework that protocols can adopt to provide legal protection for security researchers rescuing funds during active exploits, removing liability concerns for whitehats conducting emergency interventions.

An extensible open-source static analysis tool for smart contract developers and auditors. Scout detects common security vulnerabilities and deviations from best practices in smart contracts written for ink!, Soroban, and Substrate. The tool supports multiple output formats, IDE integration via VS Code extension, and CI/CD pipeline integration through GitHub Actions.

An open-source static analyzer for Clarity smart contracts on the Stacks blockchain. Stacy automatically identifies common security vulnerabilities and deviations from best practices in Clarity code. The tool provides flexible analysis options, detector filtering capabilities, and includes example smart contracts demonstrating vulnerabilities and their fixes.

Professional cybersecurity services including incident response, digital forensics, vulnerability research, and technical surveillance counter measures.
