How Messiah Works

A three-layer security architecture that protects every transaction you make.

Layer 1

Website Security Scan

Inspects website code before any transaction occurs, ensuring the integrity and safety of frontend scripts.

Instant Scan

Open the extension and trigger a scan to instantly capture and analyse the current site's HTML & JavaScript.

Risk Classification

Once the scan completes, instantly displays the site's risk level so you know the danger before any wallet interaction.

Layer 2

Transaction Signing Analysis

Analyses every transaction before you sign — detecting hidden risks and surfacing clear explanations.

Transaction Inspection

Supports EIP-712, Raw Hex, and more for broad compatibility.

Risk Assessment

Real-time threat evaluation with a clear risk report.

Plain-Language Explanation

Know exactly what a transaction does before signing.

Layer 3

Smart Contract Risk Check

Aggregates threat intelligence and proprietary detection to keep you safe from contract-level exploits.

Multi-Source Intelligence

Aggregates data from leading on-chain threat databases.

Risk Rating

Classifies addresses by risk level based on history and reports.

Real-Time Warnings

Flags suspicious addresses instantly before you interact.

Built for Every Use Case

Chrome Extension

Install once, stay protected across every Web3 interaction.

Real-Time Scanning

Scans every transaction the moment it's triggered — before you sign.

Phishing Detection

Identifies malicious websites and spoofed dApps in real time, proactively blocking potential risks to your digital assets.

Smart Contract Check

Cross-references contract addresses against threat intelligence databases.
