Features and specs

What each product offers, as listed by its team.

Messiah 5 features
JavaScript 6 features
  • Distinctive Design
    Messiah by OneSavie typically features a unique and eye-catching aesthetic that stands out from mainstream disposable vape brands, appealing to users who want something different in appearance and branding.
  • Convenient Disposable Format
    As a disposable device, it requires no maintenance, charging setup, or refilling, making it easy for users to pick up and use immediately without technical knowledge.
  • Flavor Variety
    The product line often includes multiple flavor options, allowing users to choose according to their personal taste preferences.
  • Portable and Compact
    Disposable vapes like Messiah are generally lightweight and pocket-sized, making them convenient for on-the-go use without carrying extra accessories.
  • No Learning Curve
    Being a draw-activated disposable device, it's straightforward for beginners or those transitioning from smoking, with no buttons or settings to configure.
  • Wide Browser Support
    JavaScript is supported by all modern web browsers without the need for any plugins, making it highly versatile for client-side scripting.
  • Asynchronous Programming
    JavaScript supports asynchronous programming with features like callbacks, Promises, and async/await, which helps in efficiently handling tasks such as HTTP requests.
  • Rich Ecosystem and Libraries
    The JavaScript ecosystem includes a vast amount of libraries and frameworks like React, Angular, Vue, and Node.js, which streamline development processes.
  • Community Support
    JavaScript has a large and active community, providing extensive resources, documentation, and forums for troubleshooting and development advice.
  • Event-Driven
    The language is inherently event-driven, making it suitable for developing interactive web applications that react to user inputs.
  • Full-Stack Development
    With the advent of Node.js, JavaScript can be used for both client-side and server-side development, enabling full-stack development using a single language.

Possible disadvantages

  • Security Issues
    Being an interpreted language that runs in the browser, JavaScript code is visible to the user, making it susceptible to security risks such as Cross-Site Scripting (XSS).
  • Browser Compatibility
    While JavaScript itself is widely supported, different browsers may implement JavaScript functions and standards differently, leading to compatibility issues.
  • Performance
    JavaScript is generally slower than compiled languages such as C++ or Java. Heavy computations can lead to performance bottlenecks.
  • Single Inheritance
    JavaScript uses prototypal inheritance instead of classical inheritance, which can be confusing for developers coming from object-oriented programming backgrounds.
  • Dynamic Typing
    JavaScript's dynamic typing can lead to runtime errors that are hard to debug, as variable types are checked at runtime rather than during compilation.
  • Fragmentation
    The ecosystem has many competing libraries, frameworks, and tools, which can make it overwhelming for developers to choose the right technologies for their projects.

Questions & Answers

As answered by people managing Messiah and JavaScript.

What makes your product unique?

Messiah's answer

Messiah protects the exact moment a user gets deceived. Beyond domain blocklists, it:

  • Intercepts every wallet signing request before it reaches your wallet
  • Runs Fusion Analysis — cross-checking what a site claims to do against what you're actually signing, catching "Claim Airdrop" pages that really request unlimited token approvals
  • Detects EIP-7702 malicious delegations, an emerging attack vector most scanners misclassify as safe

Why should a person choose your product over its competitors?

Messiah's answer

Most tools rely on blocklists or transaction simulation alone. Messiah combines both with AI content analysis:

  • Site Scan — analyses the page before you connect
  • Sign Analyze — simulates asset changes and explains the risk in plain language, in five languages
  • Address Check — cross-references Etherscan, GoPlus, Chainabuse and Revoke.cash

We benchmarked it against 100 live scam sites (90% detection) and published the gaps we found — so you know exactly what it catches and what it doesn't.

How would you describe the primary audience of your product?

Messiah's answer

  • Crypto users who interact with dApps — DeFi traders, NFT collectors, and first-time wallet users
  • Institutions (exchanges, banks entering Web3) needing on-premise front-end phishing protection for their customers

What's the story behind your product?

Messiah's answer

Messiah was born from the $1.5B Bybit hack — the largest crypto theft in history, executed through a compromised front-end that made signers approve something they couldn't see.

At ETHGlobal Taipei 2025, our team built a proof-of-concept recreating that exact attack: a simulated wallet front-end with injected malicious logic, and an AI pipeline that analysed the front-end JavaScript to catch it. The project won the HashKey Chain Award (On-Chain Infrastructure Compliance Innovation) and the Celo L2 Pool Prize.

We then joined Cyberport's Web3 Pilot Scheme and spent months turning the PoC into a real product — benchmarking it against 100 live scam sites and publishing what it caught and what it missed — before launching on the Chrome Web Store.

Which are the primary technologies used for building your product?

Messiah's answer

  • Extension — TypeScript + React, built with Vite (CRXJS), Manifest V3
  • Backend — Node.js + Express (TypeScript), PostgreSQL with Drizzle ORM, Zod validation
  • AI — GPT-class LLM via a model-agnostic LiteLLM proxy (per-scan-type model routing)
  • Simulation — Alchemy transaction simulation (asset-change preview before signing)
  • Threat intelligence — MetaMask eth-phishing-detect, GoPlus, Chainabuse, Etherscan, Revoke.cash, VirusTotal

Who are some of the biggest customers of your product?

Messiah's answer

  • Individual Web3 users via the Chrome Web Store (recently launched)
  • Early-access security researchers and DeFi power users
