About

Messiah guards you at every step of your on-chain journey — before you connect your wallet to a new site, before you approve any signing request, and before you send funds to an unknown address.

**SITE SCAN**

Not sure if a site is safe? Run a scan before connecting. Messiah extracts the page structure, visible text, and external resources, then runs an AI analysis to detect:

- Phishing pages that impersonate trusted wallets, exchanges, or protocols
- Seed phrase collection forms — the clearest sign of a crypto theft attempt
- Fake login pages, fake stores, and investment fraud
- Supply chain attacks and transaction-hijacking scripts (e.g., Bybit-style frontend injection)
- Suspicious scripts, scored and cross-checked against VirusTotal

Results return in seconds with a clear risk verdict — Safe, Caution, Warning, or Danger — plus a plain-language summary and actionable findings.

**SIGN ANALYZE — TRANSACTION REVIEW**

Every time a dApp sends a signing request to your wallet, Messiah automatically opens a security review popup. This is intentional behavior — a core protection feature, not a malfunction. It gives you the chance to understand exactly what you are approving before it is committed on-chain.

The review popup shows:

**Asset Simulation** 
what will be sent, received, or approved (e.g., "Sending 500 USDC, receiving 0.2 ETH"), computed via live simulation before you sign
**AI Explanation** 
plain-language breakdown of what the request does and why it may be risky
**Risk Findings** 
specific flagged issues with severity levels
**Fusion Analysis** 
a cross-check between the site's stated purpose and the actual signing request, catching mismatches like a "Claim Airdrop" page that is really requesting unlimited token approval on a drainer contract

High-risk requests require an explicit confirmation checkbox before you can proceed, preventing accidental approvals.

Supports EVM wallets (eth_sendTransaction, EIP-712 typed data, personal_sign) and Bitcoin (PSBT, btc_sendBitcoin). You can also paste transaction data manually for analysis without auto-interception.

**ADDRESS CHECK**

Paste any EVM wallet or contract address and Messiah cross-references four independent data sources:

**Etherscan** 
contract verification status, transaction history, account age, balance
**GoPlus** 
known malicious contracts and flagged tokens
**Chainabuse**
community-reported scam wallets
**Revoke.cash**
exposure from risky token approvals

Address checks currently support Ethereum, Polygon, and Arbitrum.

**PRIVACY**

When you initiate a scan or review a signing request, the relevant page content or transaction data is transmitted to our API solely for analysis. Data is processed in real time and not stored after the request completes. Your API key is kept in your browser's local storage and is never shared with any third party.
