CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
From token economies to complex DeFi logic, we deliver contracts you can stake your business on.
- Full Lifecycle Development: Audit-ready code in
Solidity 0.8+orRust, usingOpenZeppelinlibraries and established security patterns. - Comprehensive Testing & Auditing: Rigorous unit/integration tests, plus formal verification and third-party audit preparation.
- Deployment & Management: Mainnet deployment with multi-sig setups, upgradeability patterns (
TransparentProxy,UUPS), and monitoring.

ENTERPRISE-GRADE SECURITY
Why Integrate Hardware Wallets with Chainscore
Move beyond basic wallet connections. Our integration platform provides the hardened infrastructure and battle-tested tooling required to securely manage high-value assets and sensitive operations.
02
Multi-Protocol & Multi-Device Support
Seamlessly support Ledger, Trezor, and other hardware wallets across EVM chains (Ethereum, Polygon, Arbitrum) and non-EVM ecosystems. A single integration unlocks your product for the entire hardware wallet user base.
03
Reduced Development & Maintenance Overhead
Eliminate months of R&D on secure transaction signing, device communication, and firmware compatibility. Our SDK and APIs abstract the complexity, allowing your team to focus on core product features.
< 4 weeks
Integration Time
04
Enhanced User Experience & Trust
Provide a frictionless, self-custody onboarding flow. Users connect their existing hardware wallet without seed phrase exposure, dramatically improving security perception and reducing drop-off rates.
05
Enterprise-Grade Key Management Architecture
Go beyond simple signer integration. Implement advanced patterns like multi-PIN configurations, transaction simulation, and secure session management for institutional and high-net-worth use cases.
06
Future-Proof Compliance & Audit Trails
Built-in logging, non-custodial proof generation, and structured event emission create immutable audit trails for regulatory compliance (Travel Rule, AML) and internal security reviews.

Frequently Asked Questions
Get clear answers on how we secure your smart contracts with hardware wallet integration, from process to pricing.
Our process follows a structured 4-phase methodology: 1) Discovery & Architecture (1 week): We analyze your smart contracts, define user flows, and design the secure signing architecture. 2) Development & Integration (2-3 weeks): Our engineers implement the Ledger/Trezor SDK, build the custom transaction handlers, and integrate with your frontend. 3) Security Audit & Testing (1-2 weeks): We conduct internal audits, perform penetration testing on the integration layer, and run comprehensive user acceptance tests. 4) Deployment & Handoff (1 week): We assist with mainnet deployment, provide full documentation, and initiate the support period. This results in a production-ready integration in 5-7 weeks on average.
