Hardware Wallet Interface Development

overview

FULL-STACK INFRASTRUCTURE

Custom Blockchain Development

Build, deploy, and scale custom blockchain networks tailored to your business logic.

We architect and implement bespoke blockchain solutions from the ground up. Our team delivers production-ready mainnets, sidechains, and appchains with custom consensus, tokenomics, and governance models. > Go to market with a purpose-built chain in 8-12 weeks.

Protocol Design: Custom EVM or Cosmos SDK chains, zk-rollups, and Substrate-based networks.
Core Development: Smart contracts, validators, bridges, and indexers.
Deployment & DevOps: Automated CI/CD, node orchestration, and 99.9% uptime SLA monitoring.

Our development is secured by formal verification and third-party audits. We provide full documentation, node operator tooling, and ongoing maintenance to ensure long-term network stability and performance.

Core Capabilities of Our Hardware Wallet Interface Development

We build robust, user-centric interfaces that connect your dApp to leading hardware wallets, ensuring secure transactions and a frictionless user experience.

Multi-Protocol Wallet Integration

Seamless integration with Ledger, Trezor, Keystone, and other major hardware wallets. We implement the latest standards (Web3.js, Ethers.js, WalletConnect v2) for broad compatibility and future-proofing.

Transaction Security & Signing

Architected interfaces that clearly display transaction details (to, value, data) before signing. Implements EIP-712 for typed structured data signing to prevent phishing and user errors.

EIP-712

Compliant

Signing Bypasses

Cross-Chain & Multi-Asset Support

Interfaces designed to manage assets and sign transactions across EVM chains (Ethereum, Polygon, Arbitrum), Solana, and Cosmos SDK chains from a single, unified wallet connection.

AUDITED & VERIFIED

Our Development Process for Secure Wallet Interfaces

We build hardware wallet integrations with a security-first methodology, delivering production-ready interfaces that protect user assets and accelerate your product launch.

Threat Modeling & Architecture Review

We begin with a comprehensive threat model, analyzing attack vectors specific to your application and the target hardware wallet (Ledger, Trezor, Keystone). This defines the secure communication protocol and key management architecture.

Framework

Secure SDK Integration

Implementation of hardware wallet SDKs (e.g., @ledgerhq/hw-app-eth, @keystonehq/sdk) with hardened connection layers, proper error handling, and deterministic transaction signing to prevent replay attacks.
