Real-Time Blockchain Threat Intelligence Platform

Comprehensive threat intelligence and risk detection platform that provides real-time protection for blockchain transactions and wallets. Web3Firewall delivers the industry's first Security Incident and Event Management (SIEM) system purpose-built for blockchain, combining transaction simulation, behavioral analysis, and wallet monitoring to identify and prevent threats before they execute on-chain.

Transaction Simulation & Risk Scoring

Real-time pre-signature transaction simulation validates blockchain transactions before they are signed or broadcast. The platform simulates both unsigned and signed transactions to detect malicious activity including fund drainers, phishing attempts, MEV exploits, untrusted participants, and policy violations. Delivers risk verdicts in milliseconds with three possible outcomes: Allow, Deny, or Needs Approval. Assigns real-time risk tags to transactions and addresses including OFAC sanctions matches, suspicious behavior patterns, and victim wallet indicators.

Machine Learning-Based KYT

Advanced AI-powered behavioral analysis system performs in-depth transaction monitoring and risk assessment across 14+ blockchains including Bitcoin, Ethereum, Solana, and major Layer 2 networks. Employs proprietary machine learning models that continuously scan on-chain activity, learning from historical patterns and adapting detection models based on emerging threat vectors. Analyzes transaction behavior including velocity patterns, counterparty relationships, fund flow patterns, and interaction with known risky entities. Identifies anomalous patterns and deviations from normal behavior that may indicate money laundering, fraud, or other illicit activities. Operates entirely on encrypted data using privacy-enhancing AI to protect PII and sensitive transaction details.

Wallet Monitoring & Control

Comprehensive wallet intelligence platform enables organizations to track, label, and manage wallet behavior without holding private keys. Tracks total value locked (TVL), complete address history, suspicious transaction velocity patterns, and risk tags assigned to wallets. Enables pre-signature wallet freezing and unfreezing through API calls, allowing organizations to prevent transactions from high-risk or compromised wallets before they execute. Configurable alert triggers for asset movement, repeated risk tag assignments, and impersonation attempts detected through behavioral analysis.

On-Chain Security Integration

Risk Oracle module enables DeFi protocols to enforce threat detection directly at the smart contract level. Inspects transactions in the mempool before confirmation and returns risk verdicts that smart contracts can act upon. Supports Solidity and Rust contract development with drop-in integration libraries for protocol-layer security enforcement. Provides streaming risk feeds for real-time threat intelligence integration.

Detection Capabilities

Utilizes adaptive risk scoring with behavioral heuristics and context-aware signals to reduce false positives. Flags wallet drainers, mixers, red-flag addresses, and OFAC-sanctioned entities in real time by analyzing transaction patterns and counterparty reputations. Delivers transparent, customizable policies through a no-code policy engine that allows compliance teams to configure AML/KYT and sanctions enforcement without DevOps resources. Available through RESTful API, web dashboard UI, on-chain oracles, and streaming risk feeds.

Why Choose Web3Firewall

Unlike legacy blockchain security tools that focus on post-transaction forensics, Web3Firewall provides pre-signature exploit prevention with compliance built-in. Stops exploits, policy breaches, and regulatory violations before transactions settle on-chain. Trusted by centralized exchanges, custodians, wallet providers, DeFi protocols, and infrastructure providers to protect user assets and treasury funds. Maintains a 99.5% SLA with enterprise-grade security including isolated VPC architecture, role-based access controls, MFA, and real-time monitoring via SOAR systems.
