Hardware Wallet Integration

ecure, Seamless & Scalable Crypto Wallet Support for Your DApp or Platform

At Velvosoft Private Limited, we understand that security is at the heart of any blockchain application. Whether youā€™re building a decentralized exchange (DEX), a DeFi protocol, an NFT marketplace, or a wallet platform, integrating hardware wallet support isnā€™t optional anymoreā€”itā€™s a necessity.

We offer end-to-end hardware wallet integration services for all major hardware devices, including Ledger, Trezor, SafePal, and others, ensuring your users can interact with your application safely, conveniently, and with complete peace of mind.

Why Hardware Wallet Integration Matters

In the evolving Web3 landscape, user safety and control are critical. As adoption grows, so does the threat landscape. Software wallets, though popular, remain vulnerable to malware, phishing, and hacks. Hardware wallets provide an air-gapped, offline solution to private key storage, minimizing attack vectors.

If your dApp or Web3 product doesnā€™t support hardware wallets, youā€™re potentially losing power users, long-term holders, and security-conscious investorsā€”the very users who drive meaningful growth in the ecosystem.

Thatā€™s where we come in.

Key Features of Our Hardware Wallet Integration

When you work with Velvosoft, you donā€™t just get codeā€”you get a full-stack secure experience engineered to scale.

šŸ” Secure Key Handling

We make sure that private keys never leave the device, and all signing processes happen locally inside the hardware wallet chip.

āš™ļø Smooth UI/UX

We design and optimize your wallet connection interfaces with seamless prompts, fallback strategies, and real-time error handling. We donā€™t just ā€œplug and playā€ Metamask; we build full wallet connector flows with Ledger, Trezor, and other hardware wallets via:

  • WalletConnect

  • WebHID / WebUSB / U2F

  • Trezor Connect API

  • Ledgerā€™s official libraries (LedgerJS, @ledgerhq/hw-transport)

šŸ§Ŗ Comprehensive Testing

We donā€™t ship broken integrations. We rigorously test wallet interactions, including:

  • Transaction signing

  • Smart contract interactions

  • Token approvals

  • Message signing (EIP-712, personal_sign, etc.)

  • Cross-network wallet behaviors

  • Mobile compatibility (where applicable)

šŸ”§ Maintenance & Upgrades

Wallet APIs evolve. So do browsers and protocols. We offer ongoing support and updates to make sure your integration never breaksā€”even when Trezor or Ledger releases firmware updates.

How We Work

Every project is unique. Thatā€™s why we follow a personalized, milestone-driven workflow to ensure top-notch delivery and satisfaction.

1. Requirement Analysis

We assess:

  • Your tech stack

  • Target user flow

  • Supported blockchains

  • Wallets to be integrated

  • Security expectations

2. Design & Architecture

We identify the best wallet bridge or SDK to useā€”whether it’s LedgerJS, Trezor Connect, or custom firmware communication.

We create a modular integration plan that:

  • Minimizes latency

  • Ensures future-proof compatibility

  • Is easily testable and extensible

3. Development

Our developers implement secure signing flows, UI prompts, transaction crafting, and fallback logic for each wallet. We also implement gas estimations and simulate transaction outcomes where required.

4. QA & Testing

We simulate both common and edge-case scenarios:

  • Device disconnected

  • Multiple accounts

  • Invalid signatures

  • Firmware incompatibility

You receive full testing logs, video walkthroughs, and signed approval from our security team.

5. Deployment & Documentation

We deploy your wallet integration in production or staging environments and deliver:

  • Full codebase documentation

  • UI/UX behavior document

  • Security audit summary (optional)

  • Ongoing support (if chosen)

Frequently Asked Questions (FAQ)

ā“1. Which hardware wallets should I support?

It depends on your target audience. Ledger and Trezor are the most widely used globally, but if your user base is in Asia or focuses on mobile-first wallets, devices like SafePal or Keystone may be better. We can help you decide during the consultation.

ā“2. Do you offer white-label wallet interfaces?

Yes. We can build and brand wallet connectors that match your productā€™s design. This includes custom prompts, branding on modal windows, and localized content.

ā“3. What happens when hardware wallet firmware changes?

Thatā€™s part of the ongoing maintenance we offer. If Ledger or Trezor changes their communication layer, we test and upgrade your integration accordingly. This ensures uninterrupted service.

ā“4. Can you integrate WalletConnect for hardware wallets?

Yes, many hardware wallets now support WalletConnect via mobile apps (e.g., Ledger Live, SafePal App). We support WalletConnect v2, including session management, QR code display, and mobile handoff.

ā“5. How long does integration typically take?

A standard hardware wallet integration for one blockchain and two devices (e.g., Ledger + Trezor) takes 7ā€“14 days. Complex integrations (e.g., multi-chain, custom flow) may take longer.

ā“6. Do you audit the wallet integration?

While we donā€™t perform full third-party audits ourselves, we implement audit-friendly code, provide a security overview document, and can work with your chosen auditors.

ā“7. Can I use my existing frontend/backend code?

Yes. We integrate into your existing codebase (React, Vue, Angular, etc.) or build a fresh module based on your stack. We support frontend frameworks and backend signing solutions as needed.

ā“8. Is this integration suitable for mobile DApps?

Absolutely. Many hardware wallets now offer Bluetooth or mobile connectivity. We ensure the integration works on mobile browsers or via deep linking with native apps.
