HAJ Solutions, Inc. positions itself as a technology consulting and software development company. Its services include technical architecture assessment, technology stack selection, digital transformation, custom software development, cloud infrastructure and DevOps, and blockchain/Web3 security. Its product CryptoGuardians is a MetaMask Snap focused on transaction risk analysis and security alerts before users sign transactions.
Judging by its service scope, HAJ covers a fairly complete software delivery lifecycle. In the early stage, it can provide architecture reviews, technical due diligence, and modernization planning. In the implementation stage, it offers full-stack web applications, APIs, databases, PWAs, and legacy system migration. In the later stage, it extends to cloud architecture on AWS, DigitalOcean, and GCP, as well as CI/CD, Terraform, Ansible, monitoring and alerting, and incident response. On the Web3 side, its offerings include smart contract security analysis, wallet and transaction security tools, dApp development, and blockchain integration consulting. CryptoGuardians focuses on real-time transaction analysis inside MetaMask, scam address detection, contract risk assessment, and continuous threat intelligence.
No public pricing is listed for its consulting or custom development services, which are likely handled on a project basis or under a separate statement of work. CryptoGuardians is clearly positioned as a subscription SaaS product, priced at $9.99/month. The plan includes unlimited transaction scans, real-time alerts, and priority support, with subscriptions processed through Stripe checkout.
The main advantages are its broad service coverage across traditional software engineering, cloud-native development, and Web3 security; its integration directly into MetaMask without requiring a separate app; and its emphasis on not collecting personal information or storing/sharing wallet addresses. The drawbacks are that the website lacks customer case studies, team background, SLA details, detection accuracy metrics, threat intelligence sources, API/SDK information, and technical documentation. It also does not disclose whether the product is open source or self-hostable.
HAJ is suitable for small and midsize businesses that need outsourced technology consulting, cloud and DevOps implementation, or Web3 security advisory services, as well as individuals or teams that want pre-transaction risk alerts inside MetaMask. The site does not state the accessibility situation in China. Because it involves MetaMask, Stripe, and the crypto/Web3 ecosystem, users in mainland China may need to verify network connectivity, payment availability, and compliance considerations on their own. Comparable alternatives include OpenZeppelin, Trail of Bits, Tenderly, BlockSec, GoPlus Security, and Scam Sniffer.
