Custodial & Non-Custodial Wallets

Secure, Scalable, and Tailored Crypto Wallet Solutions for Web3 Startups, Enterprises & Exchanges

At Velvosoft Private Limited, we specialize in designing and developing high-performance crypto wallets—both custodial and non-custodial—to empower blockchain businesses with secure, seamless, and scalable digital asset management systems. Whether you’re building a centralized exchange (CEX), DeFi platform, NFT marketplace, or a Web3 app, we help you launch a crypto wallet solution that’s future-ready.

Why Wallets Matter in Web3

Crypto wallets are not just tools to store digital assets. They are the user’s identity, gateway to decentralized apps, and their connection to the blockchain. Depending on your business model and user preferences, choosing between custodial and non-custodial wallets is a strategic decision.

  • Custodial Wallets: You hold the keys. Better control, smoother UX.

  • Non-Custodial Wallets: The user holds the keys. Full sovereignty and decentralization.

At Velvosoft, we help you choose, design, and build the right wallet system—backed by security, performance, and compliance.

We offer end-to-end wallet development solutions customized to your project’s needs, whether you’re building from scratch or integrating with your existing infrastructure.

  • Fintechs and crypto banks

✅ Non-Custodial Wallet Development

In these wallets, users retain control of their private keys. Perfect for DeFi apps, NFT platforms, and projects focused on decentralization and privacy.

Features:

  • Private key generation on-device

  • Seed phrase backup

  • Multi-chain support (Ethereum, BSC, Solana, etc.)

  • dApp browser integration

How It Works – Our Wallet Development Process

At Velvosoft, we follow a structured, agile-based development process to ensure your wallet is secure, scalable, and production-ready.

Step 1: Discovery & Consultation

We begin by understanding your business model, compliance needs, and end-user behavior. This helps us recommend whether a custodial or non-custodial approach is best for your use case.

Step 2: Architecture Planning

We architect the wallet infrastructure based on scalability, performance, and security standards. This includes backend systems, blockchain nodes, key management protocols, and smart contracts.

Step 3: UI/UX Design

Our design team crafts intuitive, modern interfaces for both web and mobile wallet apps. We prioritize user experience without compromising on wallet security.

Step 4: Core Wallet Development

  • Custodial: Backend wallet engine, key vault setup (e.g., HSM or MPC), KYC/AML integration.

  • Non-Custodial: On-device key generation, seed phrase management, transaction signing tools.

Step 5: Blockchain Integration

We integrate the wallet with one or multiple blockchains (Ethereum, BNB Chain, Polygon, Solana, Tron, etc.), ensuring full compatibility with tokens, NFTs, and smart contracts.

Step 6: Security Testing

All wallets go through multi-layered security testing: penetration tests, key leak simulations, front-end vulnerabilities, and transaction signing verifications.

Step 7: Deployment & Support

We help you go live with full documentation and training. Post-launch, we offer dedicated support and maintenance, including regular security audits and feature upgrades.

Frequently Asked Questions (FAQs)

1. What’s the difference between custodial and non-custodial wallets?

A custodial wallet is controlled by a third party (usually the platform). A non-custodial wallet allows users to retain full control over their private keys and funds. Custodial wallets are better for simplified onboarding; non-custodial wallets are preferred in DeFi and privacy-focused apps.

2. Which wallet is more secure?

Both can be secure if implemented properly. Custodial wallets carry centralized risks but can include institutional-grade security. Non-custodial wallets rely on user discipline—if users lose their private keys, funds are gone. Velvosoft designs both with rigorous security layers.

3. Can I launch a white-label wallet under my brand?

Absolutely. We offer white-label wallet development for both custodial and non-custodial systems. You can launch your branded wallet with custom features and UI in as little as 3-5 weeks.

4. How long does wallet development take?

It depends on complexity and integrations. A basic wallet MVP takes 3–4 weeks. A fully featured wallet with mobile apps, cross-chain support, and custom APIs may take 6–12 weeks.

5. Do you support multi-chain wallet development?

Yes. We support multi-chain wallets that let users manage assets from Ethereum, Binance Smart Chain, Polygon, Solana, and more—all in one interface.

6. Can the wallet integrate with my existing DApp or DeFi product?

Yes. We can integrate wallet modules with your existing Web3 infrastructure, including staking, token swaps, liquidity pools, DAO voting, and more.

7. Do you provide ongoing support after deployment?

Yes, we offer post-launch support, maintenance, and upgrades. This includes bug fixes, feature rollouts, blockchain updates, and compliance changes.
