0–100, higher is better. How it is calculated

Onchain Heroes is a blockchain-based idle RPG game that operates fully onchain, emphasizing trustless and verifiable gameplay without centralized servers. The project is live on Abstract Chain with an active community exceeding 10,000 members and backing from several angel investors. The website presents a professional design with clear branding and consistent messaging targeted at blockchain gaming enthusiasts and degens. Technically, the site is built using modern web technologies including React and Next.js, delivering a moderate performance with good mobile optimization and SEO practices. The absence of privacy and cookie policies, as well as contact information, limits the site's compliance posture. Security-wise, HTTPS is enforced, but security headers and incident response details are missing, indicating room for improvement. Overall, the website is functional and trustworthy within its niche, but lacks critical compliance and security documentation. The domain uses privacy protection common in the blockchain sector, which slightly reduces transparency but is not unusual. Strategic improvements in privacy, security policies, and contact transparency would enhance trust and compliance.

This scan rated NIS2 with an earlier keyword method that is no longer shown; rescan for the per-article view. Risk management, continuity, supply chain, training, MFA, management oversight (Art. 20) and incident reporting (Art. 23) need internal evidence, and Guard cannot tell whether NIS2 applies to this organisation.

GDPR is indicative only, based on publicly visible signals: Articles 7, 12, 13 and 32 of Regulation (EU) 2016/679 and Article 5(3) of the ePrivacy Directive. Not a certification or legal assessment.

Priority findings

8 findings rated critical or high. Fix these first.

  1. Email security

    SPF, DKIM and DMARC stop others sending email that looks like it comes from your domain, a common route to phishing and invoice fraud.

    • Critical

      No email authentication configured

      Domain is vulnerable to email spoofing

      What to do: Implement SPF, DKIM, and DMARC immediately

  2. Security headers

    Security headers are instructions your web server sends to every visitor’s browser. Missing ones leave visitors more exposed to attacks such as clickjacking and injected scripts.

    • High

      Missing X-Frame-Options header

      Prevents clickjacking attacks

      What to do: Add "X-Frame-Options: DENY" or "X-Frame-Options: SAMEORIGIN"

    • High

      Missing Content-Security-Policy header

      Controls resources the browser is allowed to load

      What to do: Implement a Content-Security-Policy appropriate for your application

      • ASVS V3.4.3
      • OWASP Secure Headers: OWASP Secure Headers Project recommends Content-Security-Policy: default-src 'self'; form-action 'self'; base-uri 'self'; object-src 'none';…

  3. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

    • High

      No Cookie Policy found

      GDPR requires clear information about cookie usage

      What to do: Add a dedicated cookie policy explaining cookie usage and purposes

Results by check

Each check with its score, findings and the evidence it collected.

How this score is calculated

The security score runs 0–100, higher is better. It is the plain average of the security checks that completed in this scan, each counted equally. A check that could not run is left out: it counts neither as a pass nor as a fail.

Not counted

  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

Findings that cap the score at 49

Each of these is serious on its own, so while any is present the site cannot rate better than high risk, however good the other checks are.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

Partial scans

When the site blocks Guard or most checks cannot run, the score covers only the checks that ran (usually DNS and email), is capped at 75 and is shown as partial, without a risk level.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

Onchain Heroes occupies a niche in the blockchain gaming market, offering a fully onchain idle RPG experience. Its competitive advantage lies in novel onchain game mechanics and a trustless gameplay model. The business model likely includes monetization through gameplay, NFTs, or tokenomics. The project has secured angel investment and maintains an active community, signaling growth potential. Partnerships are primarily social media and community-focused, with no evident payment processors or subsidiaries. The founder's background in web3 gaming adds credibility. The target audience is blockchain gamers and degens seeking innovative gaming experiences.

Security posture

The website demonstrates a basic to moderate security maturity level. HTTPS is properly implemented, ensuring encrypted communications. However, the lack of security headers such as Content-Security-Policy and absence of a published security policy or incident response contacts indicate gaps in security best practices. No vulnerabilities or exposed sensitive data were detected in the HTML content. The absence of privacy and cookie policies also reflects compliance gaps. Overall, the security posture is adequate for a small blockchain gaming project but requires enhancements to meet higher standards and regulatory compliance.

Recommendations

  1. Publish a comprehensive privacy policy and cookie policy to improve compliance and user trust.
  2. Implement and display terms of service and a security policy outlining security practices and user responsibilities.
  3. Add clear contact information including security incident response contacts to facilitate communication and trust.
  4. Enhance security headers (e.g., Content-Security-Policy, X-Frame-Options) to mitigate common web vulnerabilities.
  5. Consider establishing a vulnerability disclosure program and hosting a security.txt file to encourage responsible reporting.

Technical notes

Notes

The website is built on a modern React and Next.js stack, leveraging server-side rendering and optimized image loading. The use of web3-related external domains indicates integration with blockchain services. Performance is moderate with good mobile responsiveness and SEO meta tags present. No CMS or hosting provider details were identified. The site lacks advanced accessibility features but maintains basic usability. No analytics or tracking scripts were detected, indicating minimal user tracking. Technical debt appears low, but the absence of security headers and compliance documentation suggests areas for modernization and risk mitigation.
Standards and sources

Reference chips under each finding point to the standard, regulation or specification the finding relates to. They are taken from the official datasets below and mapped conservatively: a finding with no defensible link shows none. NIS2 and GDPR references mark where a finding is relevant evidence, not a compliance verdict. Implementing Regulation (EU) 2024/2690 binds digital infrastructure and digital service providers; for other entities it is the most detailed public reading of the Article 21 measures. WCAG, EN 301 549, European Accessibility Act and Web Accessibility Directive references name the requirement an automated accessibility rule relates to; they are not a conformance verdict.
