Questions & Answers

As answered by people managing JavaScript.com and Messiah.

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
