CORE INFRASTRUCTURE
Smart Contract Development
Secure, audited smart contracts built for production from day one.
We don't just write code; we engineer resilient systems with built-in safeguards and clear upgrade paths.
- Full Lifecycle Development: From initial design and
Solidity/Rustcoding to deployment and post-launch monitoring. - Security by Default: All contracts undergo rigorous internal audits and are built with
OpenZeppelinstandards. We prepare for third-party audits from firms like CertiK or Quantstamp. - Production-Ready Features: Includes pause mechanisms, multi-sig admin controls, proxy patterns for upgrades, and comprehensive event logging.
- Deliverables: Fully documented source code, deployment scripts, and a technical spec for your team.

ENTERPRISE-GRADE INFRASTRUCTURE
Business Outcomes: Secure, Compliant Operations
Multi-signature hardware wallet integration is not just a security feature—it's a foundational business requirement for institutional adoption. We deliver production-ready systems that meet the highest standards for security, compliance, and operational control.
01
Institutional-Grade Security Posture
We implement multi-sig with Ledger Enterprise or Trezor Enterprise devices, ensuring private keys never leave certified hardware. Our architecture isolates signing ceremonies from hot systems, eliminating single points of compromise.

Regulatory & Audit Readiness
Our systems generate immutable, on-chain logs for all proposal creation, approvals, and executions. This provides a transparent, verifiable audit trail for internal compliance teams and external regulators (SEC, FINRA, MiCA).

Strategic Decision Analysis
Build vs. Buy: Hardware Wallet Multi-Sig Integration
A detailed comparison of the total cost, risk, and resource commitment required to develop a secure multi-signature hardware wallet solution in-house versus partnering with Chainscore Labs.
| Factor | Build In-House | Chainscore Integration |
|---|---|---|
Time to Production | 6-12 months | 4-8 weeks |
Initial Development Cost | $150K - $400K+ | $25K - $75K |
Security Audit Requirement | Mandatory ($50K - $150K) | Included (Pre-Audited Modules) |
Ongoing Maintenance & Updates | Full internal team required | Managed service with optional SLA |
Expertise Required | Senior Solidity, Hardware Security, Cryptography | Provided by our team |
Integration Complexity | High (Ledger/Trezor SDKs, Secure Element) | Low (API & SDK-based) |
Key Management Risk | High (custody of custom secure enclaves) | Low (leverages battle-tested hardware) |
Total Year 1 Cost (Est.) | $250K - $600K+ | $50K - $150K |
Time-to-Value | Slow (High upfront investment) | Fast (Weeks to secure treasury) |

Frequently Asked Questions
Get clear answers on timelines, security, and process for integrating enterprise-grade multi-signature hardware wallets.
A standard integration project for a protocol like Gnosis Safe or Safe{Core} with Ledger/Trezor support takes 2-4 weeks from kickoff to production deployment. Complex deployments with custom signing logic or support for 5+ hardware vendors may extend to 6-8 weeks. We provide a detailed project plan with weekly milestones during discovery.
