KYC/Whitelist Management Systems

Secure, Compliant, and Scalable Identity Verification Solutions for Blockchain Projects

At Velvosoft Private Limited, we understand that regulatory compliance and user security are crucial to the success and sustainability of any blockchain or decentralized application (dApp). Whether you’re launching a new token, operating a DeFi platform, managing an IDO/ICO/IEO, or building a custom dApp that requires user-level permissions—KYC (Know Your Customer) and Whitelist Management Systems are essential components.

Our KYC/Whitelist Management System is designed to help Web3 projects streamline identity verification, enforce regional compliance laws (like AML/CFT regulations), and manage investor onboarding effortlessly. With over a decade of experience in blockchain development, Velvosoft provides custom, fully integrated KYC and whitelist solutions tailored for your project’s needs.

Why KYC and Whitelist Management Matter in Web3

Many blockchain-based projects, particularly in DeFi, gaming, token sales, and governance protocols, face one common challenge—how to balance decentralization with legal compliance and security. Regulatory frameworks across the world are tightening, and failure to comply can lead to shutdowns, fines, and loss of user trust.

By integrating robust KYC and whitelist modules, you can:

  • Ensure legal compliance in your operational jurisdictions.

  • Prevent Sybil attacks, fraud, and fake identities.

  • Filter out restricted countries and sanctioned users.

  • Build trust with investors and institutional partners.

  • Simplify tier-based or role-based user permissions.

  • Easily manage token sale participation through verified addresses.

What We Offer

📜 Whitelist Management System

Velvosoft’s whitelist system allows projects to define eligibility criteria and control who can participate in your ecosystem—whether it’s token sale access, governance voting, or reward distribution.

Capabilities include:

  • Manual and automated whitelisting.

  • Wallet address binding with identity records.

  • IP/geolocation restrictions to enforce regional bans.

  • Smart contract-level access control.

  • Tier-based access based on user credentials or past activity.

  • Google Sheets or backend API sync for flexible management.

How Our System Works – Step-by-Step

Here’s how a typical KYC/Whitelist system works when integrated with your platform by Velvosoft:

1. User Registration

Users register on your platform using their email address or wallet authentication (Web3 login like Metamask, WalletConnect, etc.).

2. KYC Form Submission

The user fills out a form providing identity documents like passport, national ID, selfie, proof of address, etc. These forms are powered via third-party KYC API or your custom backend.

3. Document Review & Verification

Documents are verified using automated and/or manual review by KYC service providers. The verification status is updated in the backend.

4. Whitelist Generation

Upon successful KYC approval, the user’s wallet address is automatically added to the whitelist.

Alternatively, if KYC is not required but a whitelist is, the admin can approve users manually or from a third-party database (e.g., Google Form submission).

5. Smart Contract Access Control

Smart contracts on your platform are configured to only allow actions (e.g., participate in a token sale, stake, vote) for whitelisted addresses.

6. Audit & Compliance Logs

Every user action, verification status, and whitelist entry is logged and stored securely for regulatory audits.

Use Cases of Our KYC/Whitelist System

  • Token Launch Platforms (ICO/IDO/IEO): Control who can buy tokens.

  • NFT Marketplaces: Restrict minting and airdrops to verified users.

  • Staking Platforms: Limit staking participation to certain regions or users.

  • Governance Platforms: Allow only KYC’d users to vote or propose changes.

  • Metaverse Projects: Enforce identity-based entry for real-world integration.

  • Gaming Platforms: Prevent abuse of reward systems with multiple accounts.

Our Approach – Built for Scalability & Customization

At Velvosoft, we don’t believe in one-size-fits-all. Every project has unique compliance requirements, tokenomics, and audience geography. That’s why we build your KYC/Whitelist System from scratch—or customize our existing modules—to align perfectly with your goals.

You choose:

  • Self-hosted or SaaS model.

  • Backend-only API or full frontend interface.

  • Custom document requirements (e.g., nationality filters).

  • Automated vs. manual approval flow.

  • On-chain vs. off-chain whitelist verification.

We ensure seamless integration with your existing token contracts, frontend UI, and admin dashboard.

Frequently Asked Questions (FAQ)

1. Is your KYC system fully compliant with international regulations?

Yes. We implement systems that follow KYC/AML guidelines and are compatible with GDPR, FATF recommendations, and local compliance laws. We can integrate providers who are globally compliant and allow regional filters as per your business needs.

2. Can I use my own KYC provider instead of the one you suggest?

Absolutely. We offer flexible integrations and can work with Sumsub, Veriff, ShuftiPro, IdentityMind, or any API-based provider of your choice.

3. Is the whitelist stored on-chain or off-chain?

It depends on your preference. We support both models:

  • On-chain whitelist for contract-level control.

  • Off-chain whitelist for backend logic with signature-based verification.

4. Can I restrict participation based on geography or IP address?

Yes. Our whitelist system can include IP-based geolocation filters and country restriction logic. This helps you remain compliant with sanctions or regulatory bans.

5. How long does it take to integrate KYC/Whitelist into my project?

Typically, the entire setup takes 5–10 business days, depending on the complexity of your project and the number of customizations needed.

6. Do I need a backend developer on my team to manage this system?

No. We provide you with an easy-to-use admin dashboard where you can view users, approve KYC, export whitelist addresses, and manage compliance reports.

7. What happens if a user fails KYC?

They will not be added to the whitelist and will be restricted from participating in your token sales or other protected areas. You can also configure automatic notifications or appeal workflows.

8. Is the data stored securely?

Yes. All sensitive user data is stored in encrypted databases, with SSL/TLS in transit. We follow best practices for data security and can deploy on your own server for complete data ownership.

9. Can I issue NFTs or tokens only to whitelisted users?

Yes, absolutely. Our system can link verified wallet addresses to token or NFT minting rights, ensuring only eligible users receive assets.

10. Can this be used in a DAO or governance model?

Yes. We can help integrate your KYC/whitelist logic with governance frameworks (Snapshot, Tally, custom dApps) to allow only verified users to vote or propose changes.
