What MythX does
MythX was a cloud-based smart contract security analysis service for Ethereum and EVM-based blockchains, operated as a service brand of ConsenSys AG and built by the ConsenSys Diligence team. The platform combined three complementary analysis techniques, static analysis of Solidity source via AST parsing, symbolic execution to detect vulnerable program states, and greybox fuzzing to find vulnerable execution paths, running them as coordinated parallel microservices. It offered three scan modes (Quick at 2 minutes, Standard at 15 minutes, and Deep at 45 minutes) accessible through a web dashboard, REST API, CLI (MythX-CLI), official JavaScript/TypeScript and Python libraries (MythX-JS, PythX), and IDE integrations with Truffle, Remix, VS Code, and Brownie. Detection coverage was anchored to the SWC Registry (SWC-101 through SWC-134 and additional non-SWC detectors), with TLS-encrypted submissions and reports pinpointing vulnerable source lines and transaction traces.
MythX made money through monthly SaaS subscriptions tied to scan modes and computing-time allocations, usage-based scan packs, and a 25% revenue share for tool builders integrating the API. Go-to-market was product-led and API-first, combining self-serve developer onboarding, Discord-driven community, and a 25+ partner ecosystem spanning smart contract auditors (Quantstamp, Chainsecurity, SmartDec, Quil Audits), analytics platforms (Amberdata, Anchain), enterprise blockchain providers (Kaleido, EEA), and regional security firms (Haechi, Sooho, NRI Secure, SECBIT). Primary customers were Ethereum smart contract developers and Web3 companies seeking automated pre-audit scanning, with named enterprise references including Aave (DeFi) and 0x (DeFi protocol v3.0 release). The MythX suite was sunset on March 31, 2023; Mythril remains open source, Harvey evolved into the Diligence Fuzzing product under ConsenSys Diligence, and Maru was archived with potential future open sourcing.

MythX product offering
Product offeringCore offering
MythX was a smart contract security-as-a-service platform for Ethereum and EVM-based blockchains that combined static analysis, symbolic execution, and greybox fuzzing in parallel microservices to detect security vulnerabilities. It exposed three scan modes (Quick, Standard, Deep) via a web dashboard, REST API, and CLI, with integrations into developer tools such as Truffle, Remix, VS Code, and Brownie.
Product overview
MythX was a security analysis service for Ethereum and EVM-based blockchain smart contracts, functioning as a unified platform that combined multiple analysis techniques. The core MythX platform offered three scan modes (Quick, Standard, and Deep) with varying analysis depths, accessible via the MythX Dashboard, REST API, and CLI. The product ecosystem included official tooling: MythX-CLI (command-line interface), MythX-JS (TypeScript library), PythX (Python library), and the MythX VSCode extension. Community integrations extended support to Remix IDE, Truffle, Brownie, Whiteblock, and Guardrails. The underlying technology components included Mythril (remaining open source), Harvey (evolved into Diligence Fuzzing), and Maru (archived). The service was sunset on March 31st, with users directed to Diligence Fuzzing as the successor offering.

MythX competitors and assessment
Company assessmentDirect peers
- OpenZeppelin: Provides smart contract security tools (e.g., Defender) and audit services. Overlaps directly with MythX's developer-focused security tooling positioning.
- Hosho: Smart contract auditing firm serving enterprise and DeFi clients. Comparable to MythX's audit-preparation use case on the services side of the smart contract security stack.
- Trail of Bits: Security firm with deep blockchain practice and the creators of Slither (static analysis) and Echidna (fuzzing) for EVM. Competes at both the tool and audit layer.
- CertiK: One of the largest smart contract security firms, offering automated scanning, formal verification, and audits for EVM and non-EVM chains. Directly competes with MythX's smart contract vulnerability detection positioning.
- SlowMist: Blockchain security firm offering smart contract audits and on-chain threat monitoring. Competes in the same Ethereum security auditing niche with a broader services portfolio.
- Runtime Verification: Formal verification and smart contract security firm. Comparable to MythX in its emphasis on deep correctness analysis and symbolic techniques for EVM contracts.
- Quantstamp: Smart contract auditing and automated security analysis platform. Was also a MythX integration partner, making it a particularly close comp in both product and ecosystem role.
- ChainSecurity: Smart contract security firm behind the Securify static analyzer. Competes with MythX's automated vulnerability detection offering and was also a MythX partner.
Broad incumbents
- ConsenSys Diligence: Parent organization of MythX and the team that built it. Diligence now offers Diligence Fuzzing as the successor product, making it the closest internal incumbent to the discontinued MythX suite.
Emerging players
- Solidified: Smart contract audit marketplace connecting projects with security experts. Adjacent to MythX's pre-audit preparation value proposition, though delivered as a marketplace rather than a SaaS engine.
