Real-Time Transaction Policy Enforcement for Web3

Web3Firewall is a Web3-native SIEM and SOAR platform that ingests both on-chain and off-chain telemetry, simulates transactions, and enforces real-time risk and compliance policies before execution.

By allowing, denying, or quarantining transactions pre-signature, it transforms blockchain security from passive detection into active prevention.

The platform gives enterprises full cross-chain visibility and automated control over every transaction path—enabling them to stop threats, enforce compliance, and reduce financial risk in real time.
Behavioural and anomaly detection
Transaction simulation before signing
AML/KYT & OFAC rule enforcement
Dynamic policy engines for sanction/red flag rules
Fully API-first infrastructure for integration and whitelabel use
It targets both on-chain actors like DEXs and off-chain operations like CEXs via UI, API, and on-chain oracle modules.

Your First Line of Defence Becomes Your Full Compliance Stack

Start with real-time transaction simulation. Scale into full-spectrum compliance, sanctions screening, anomaly detection, and policy enforcement—all in one unified platform.

Pre-Signature Trust Layer
Validate and simulate transactions before you admit. Stop exploits, mixers, and OFAC violations at the source.
‍
MPC & Wallet-Ready
Easily embed into any wallet, MPC solution, or multisig stack. No key management needed—just one API call to simulate and enforce.
From Wedge to OS
Begin with risk-scoring. Expand to transaction logging, forensic history, sanctions mapping, and regional policy frameworks (e.g. MiCA, FATF, FCA).

Transaction Simulation & Risk Scoring

Pre-broadcast visibility. Real-time risk verdicts.
Simulate transactions before they’re signed or broadcast. Get a verdict in milliseconds, flag anomalies, and block attacks before they cost you gas or reputation.

Simulate unsigned or signed transactions

Detect fund drainers, untrusted participants, and policy violations

Integration via API or Dashboard UI

Real-time risk tags (e.g. OFAC, Suspicious, Victim)

Instant verdicts: ✅ Allow / ❌ Deny / 🟠 Needs Approval

Custom Risk Policy Engine

Programmable compliance logic for pre- and post-broadcast enforcement.
Define how your platform handles each type of risk across jurisdictions, asset classes, and user behavior.

Pre-signature enforcement: Block/Allow/Alert on incoming or outgoing transactions

Post-broadcast triggers: Alert on-chain anomalies or escalations

Granular risk actions: Auto-deny OFAC, quarantine “victim” wallets

Visual rule builder or JSON config (no-code & low-code both supported)

Wallet Monitoring Toolkit

Investigate. Flag. Freeze.
Powerful intelligence tools to track, label, and control wallet behavior without managing private keys.

Track TVL, address history, suspicious velocity, tags

Freeze/unfreeze wallets pre-signature via API

Alias assignment for known keys (“Team A Treasury”)

Alert triggers for asset movement, repeated risk tags, or impersonation attempts

Risk Oracle (On-Chain Enforcement)

Smart contract-level security using programmable policy logic.
Enable DeFi protocols and on-chain systems to read risk verdicts in-line before confirming any transaction.

Solidity/Rust-ready contract integration

Mempool transaction inspection + on-chain verdict return

Call readRiskFlag() to allow, block, or require multi-sig

Works without off-chain runtime dependencies

Optional simulation support before enforcement

VASP Reports & Counterparty Intelligence

Know Your Counterparty (KYC/KYB) in Web3.
For regulated entities needing compliance-grade transparency into who they’re dealing with.

KYC/KYB summaries on counterparties, clusters, and VASP registrants

Exportable reports for internal audit or regulator response

Pricing model: pay-per-entity or monthly tiers
