NZOChain detects dangerous permissions, malicious contracts, wallet drainers and suspicious connections before your assets are compromised.
The problem is not only getting hacked. The problem is finding out too late.
Unlimited approvals allow contracts to move your tokens without limits.
Tokens falsos e smart contracts maliciosos drenam carteiras silenciosamente.
Cloned interfaces trick users into giving away access and signatures.
Many users only notice the hack after the funds are gone.
Modern Web3 security infrastructure for users and companies.
Risk detection on scan and scheduled opt-in re-scan (every 6h) — this is not real-time monitoring.
Review risky approvals and, on eligible plans, submit revocation — you sign in your wallet; it completes only after on-chain confirmation.
We identify malicious tokens, suspicious contracts and hidden risks.
Integrate Web3 security directly into your product or company.
MetaMask, WalletConnect and multiple networks.

The protection layer is designed for the chains your users already trust and transact on daily.
Connect familiar wallets (MetaMask, WalletConnect, Phantom, Trust, Coinbase). The scan engine covers four EVM networks — Phantom as a connector does not mean Solana support.
Direct answers for users, teams and partners evaluating the protection layer.
Use NZOChain's API to get on-demand risk scores for a wallet address. The system analyzes transaction history, connections to known scam addresses and behavioural patterns to provide an advisory RiskScore from 0 to 100.
NZOChain provides a Web3 risk scoring API for supported EVM networks (Ethereum, BNB Chain, Polygon, Arbitrum), with scheduled opt-in re-scan (every 6h), webhook alerts for revocation.completed and transaction analysis. Select a provider based on your supported chains, security requirements and product risk policy.
NZOChain webhooks currently dispatch revocation.completed. Additional webhook events are on the roadmap. To track risk over time, combine scheduled opt-in re-scan (every 6h, when enabled) with manual or on-demand API scans — this is not continuous or real-time monitoring.
NZOChain separates consumer and developer pricing. B2C plans: Free 0 USD, Basic 4.99 USD, Pro 9.99 USD, Premium 19.99 USD per month. B2B API plans: Free 0 USD, Starter 49 USD, Growth 149 USD, Business 499 USD per month, plus Enterprise custom pricing. Monthly per-key quotas: Free 1k / Starter 25k / Growth 100k / Business 500k.
