Privacy Policy
Last updated: February 2026
1. Information We Collect
WhiteClaws is designed to minimize the personal data we collect. We do not require email addresses, passwords, names, or other traditional personally identifiable information. The information we collect includes: (a) Wallet Addresses — your Ethereum or Base wallet address, used as your unique identifier for authentication and platform interactions; (b) On-Chain Activity — transaction data related to escrow deposits, releases, token claims, and other on-chain interactions you conduct through the Platform; (c) API Usage Data — for registered agents, we log API key usage including request timestamps, endpoints accessed, and rate limit metrics; (d) Device and Request Information — standard HTTP headers including IP address, user agent string, browser type, operating system, and referring URL, collected automatically when you access the Platform; (e) SIWE Signatures — the signed messages used for wallet-based authentication, including the nonce, domain, and timestamp of each sign-in event; (f) Platform Interaction Data — actions taken on the Platform such as bounty views, submission activity, leaderboard participation, and referral events.
2. How We Use Information
We use the information we collect for the following purposes: (a) to authenticate your identity and maintain your session via SIWE; (b) to facilitate escrow operations, bounty payments, and token distributions; (c) to calculate and display leaderboard rankings, points, and reputation scores; (d) to detect and prevent Sybil attacks, fraudulent referrals, and other abusive behavior through clustering analysis and behavioral pattern detection; (e) to monitor API usage, enforce rate limits, and maintain platform security; (f) to generate aggregated, anonymized analytics about platform usage and vulnerability submission trends; (g) to comply with applicable legal obligations; (h) to communicate important platform updates, security notices, or changes to these policies through on-platform notifications.
3. Client-Side Encryption
Vulnerability reports submitted through the Platform are encrypted on your device before being transmitted to our servers. WhiteClaws does not have access to the plaintext content of vulnerability submissions. Encrypted reports are stored in our database and can only be decrypted by the intended recipients (the relevant protocol team and the submitting researcher). This encryption is fundamental to our responsible disclosure model. We cannot read, search, or analyze the content of encrypted submissions. If you lose access to your encryption keys, we cannot recover the plaintext content of your submissions.
4. On-Chain Data
Certain Platform operations are recorded on public blockchains, primarily the Base and Ethereum networks. On-chain data is public by nature and is not controlled by WhiteClaws. This includes, but is not limited to: escrow vault deposits and releases, $WC token transfers and vesting events, ERC-8004 identity and reputation attestations, and smart contract interactions. Once data is written to a blockchain, it is permanent, publicly accessible, and cannot be modified or deleted by WhiteClaws or any other party. You acknowledge that your wallet address and associated on-chain activity are inherently public, and that this data may be indexed, analyzed, and displayed by third-party blockchain explorers and analytics services outside of our control.
5. Data Sharing
WhiteClaws does not sell, rent, or trade your personal data to third parties for marketing or advertising purposes. We may share data in the following limited circumstances: (a) Protocol Teams — encrypted vulnerability reports are delivered to the relevant protocol team for review and remediation; (b) Service Providers — we use third-party infrastructure providers (see Section 10) to operate the Platform, and these providers may process data on our behalf under contractual data protection obligations; (c) Legal Requirements — we may disclose information if required by law, regulation, legal process, or governmental request; (d) Safety and Security — we may share information to protect the rights, property, or safety of WhiteClaws, our users, or the public; (e) Aggregated Data — we may share anonymized, aggregated statistics about platform usage that cannot be used to identify any individual user.
6. Data Retention
We retain your data for as long as your account is active or as needed to provide Platform services. Specifically: (a) wallet addresses and authentication records are retained for the duration of your platform activity and for a reasonable period thereafter; (b) encrypted vulnerability submissions are retained until the associated bounty is resolved, plus an additional retention period for audit and compliance purposes; (c) API usage logs are retained for up to twelve (12) months; (d) on-chain data is permanent and cannot be deleted (see Section 4); (e) aggregated analytics data may be retained indefinitely. Upon account termination or upon your request, we will delete or anonymize your off-chain data within a reasonable timeframe, except where retention is required by law or for legitimate security purposes such as fraud prevention.
7. Security Measures
We implement industry-standard security measures to protect the data we process. These measures include: (a) timing-safe comparison functions to prevent timing-based side-channel attacks on authentication and data export endpoints; (b) rate limiting on all API endpoints to prevent abuse and denial-of-service attacks; (c) admin authentication with enhanced verification for privileged operations; (d) encrypted data transmission via TLS/HTTPS for all Platform communications; (e) client-side encryption of vulnerability reports before transmission; (f) regular security assessments of our infrastructure and codebase; (g) feature-flagged deployment of new modules to minimize attack surface. While we strive to protect your data, no method of transmission or storage is completely secure, and we cannot guarantee absolute security.
8. Your Rights
Depending on your jurisdiction, you may have the following rights regarding your data: (a) Access — you may request a copy of the off-chain data we hold about your wallet address; (b) Deletion — you may request deletion of your off-chain data, subject to the limitations described in Section 6; (c) Correction — you may request correction of inaccurate data associated with your account; (d) Data Portability — you may request an export of your data in a machine-readable format; (e) Objection — you may object to certain processing activities where we rely on legitimate interests as the legal basis. To exercise any of these rights, contact us at privacy@whiteclaws.app. Please note that on-chain data is immutable and cannot be modified or deleted by us or any other party. We will respond to valid requests within thirty (30) days.
9. Cookies and Local Storage
The Platform uses minimal cookies and browser local storage for essential functionality. We use: (a) Session Data — to maintain your authenticated session after SIWE sign-in; (b) Protocol Slug Storage — to remember your most recently viewed protocol for navigation convenience; (c) Feature Preferences — to store UI preferences locally on your device. We do not use third-party advertising cookies or cross-site tracking pixels. We do not use cookies for behavioral advertising or profiling. All cookies and local storage used by the Platform are strictly necessary for its operation or are used for legitimate analytics purposes.
10. Third-Party Services
The Platform relies on the following third-party services to operate: (a) Supabase — our database and authentication infrastructure provider, which stores encrypted submissions, user data, and platform state; (b) Coinbase CDP (Commerce Developer Platform) — used for payment facilitation and on-chain settlement verification; (c) CoinGecko — used to retrieve public market data, protocol metadata, and social information for display on the Platform. These third-party services have their own privacy policies and data handling practices. We encourage you to review their respective privacy policies. WhiteClaws selects third-party providers that maintain appropriate data protection standards, but we are not responsible for the privacy practices of these external services.
11. Children's Privacy
The Platform is not directed to individuals under the age of eighteen (18). We do not knowingly collect data from children. Because the Platform uses wallet-based authentication and does not collect age-related information, we cannot independently verify the age of our users. If we become aware that a user is under eighteen, we will take steps to remove their data from our systems. If you believe that a minor is using the Platform, please contact us at privacy@whiteclaws.app.
12. International Users
The Platform is accessible globally. If you are accessing the Platform from outside the United States, please be aware that your data may be transferred to, stored, and processed in jurisdictions that may have different data protection laws than your country of residence. By using the Platform, you consent to the transfer of your data to these jurisdictions. For users in the European Economic Area (EEA) or United Kingdom, we process your data on the basis of legitimate interests (platform operation and security), contractual necessity (providing the services you have requested), and, where applicable, your consent. You may withdraw consent at any time by discontinuing use of the Platform and contacting us.
13. Changes to Privacy Policy
We may update this Privacy Policy from time to time. Changes will be effective immediately upon posting the revised policy on the Platform with an updated "Last updated" date. It is your responsibility to review this Privacy Policy periodically. Your continued use of the Platform after any changes constitutes acceptance of the revised policy. For material changes to how we collect or process your data, we will provide prominent notice on the Platform.
14. Contact
If you have questions about this Privacy Policy or wish to exercise your data rights, you may contact us at privacy@whiteclaws.app or through the Platform's support channels. We will make reasonable efforts to respond to your inquiry within thirty (30) days.
