About Web3Firewall
Web3Firewall provides transaction-level security and compliance for digital asset institutions, moving the control point ahead of signing. It simulates unsigned or signed but unbroadcast transactions, reconstructing asset movements, state changes and counterparties, then layers behavioural baselines, anomaly detection, sanctions lists and custom policy to return allow, deny or escalate; policies can be scoped by wallet, sub-account, asset and jurisdiction and map to MiCA, OFAC and FATF language. An on-chain edition ships as a risk oracle, so contracts can call a read function before confirming and write policy enforcement into the settlement path.
The line-up covers an API, a console, a smart contract oracle and a streaming risk feed, sold to exchanges, custodians, wallets, payment providers and protocols and a white-label multi-tenant edition for managed service providers. Unlike analytics tools that reconstruct events after the fact, it sells decision rights before execution. Blocking depends on transactions being routed through its interface, so signing flows that bypass it stay outside coverage, and verdicts rest on in-house threat intelligence plus customer tuning.
At the end of March 2026 Web3Firewall closed a USD 2.5 million pre-seed led by Nomura's Laser Digital with gumi Cryptos Capital and Susquehanna's SPEILLLP. The capital expands engineering and sales and moves Web3Firewall Enterprise toward full commercial release. The product replaces address-reputation-only screening with a real-time transaction policy engine that scores more than 100 pre-signature signals - transaction attributes, zero-history addresses and KYC intelligence - to catch zero-day attacks, and checks AML, KYT and Travel Rule exposure before execution.
In the second half of 2026 Web3Firewall focuses on integrations with custodians, payment firms and exchanges, product work on AI/ML false-positive self-correction and private-chain coverage, and compliance reporting aimed at regulated institutions.
