The Institutional Wallet Infrastructure Decision
Build vs. Buy vs. Chainscore
Choosing the right path for your EVM institutional wallet is critical for security, speed, and cost. This comparison outlines the trade-offs between developing in-house, using a generic third-party solution, and partnering with Chainscore Labs for custom development.
| Key Factor | Build In-House | Buy Generic Solution | Chainscore Custom Development |
|---|---|---|---|
Time to Production | 6-12+ months | 1-3 months (limited features) | 4-8 weeks (full spec) |
Upfront Development Cost | $250K - $750K+ | $10K - $50K (licensing) | $50K - $200K |
Security Posture | High risk (unaudited, novel code) | Moderate risk (shared codebase) | Low risk (audited, custom-built) |
Customization & Control | Full control, high maintenance | Limited to vendor roadmap | Full control, our team maintains |
Multi-Chain Support (EVM) | Your team builds integrations | Limited to vendor's list | Ethereum, Polygon, Arbitrum, Base, Optimism, etc. |
MPC/TSS Implementation | Complex, high-security burden | Often black-box or SaaS-only | White-label, audited MPC stack |
Compliance Features (Travel Rule, Screening) | Requires separate vendor integration | Basic features may be included | Integrated, customizable compliance module |
Ongoing Maintenance & Upgrades | Full internal team required | Vendor-managed, limited flexibility | Optional SLA with 99.9% uptime |
Total Cost of Ownership (Year 1) | $400K - $1M+ | $100K - $200K | $80K - $250K |
Best For | Teams with vast blockchain dev resources | Non-custodial apps needing basic wallets | Institutions requiring secure, branded, scalable custody |

Frequently Asked Questions
Get clear answers on timelines, security, and process for building a secure, multi-chain institutional wallet.
A production-ready institutional wallet with core custody, multi-signature, and basic DeFi integrations typically takes 6-10 weeks from kickoff to mainnet deployment. Complex features like custom policy engines, cross-chain bridging, or MPC/TSS implementations can extend this to 12-16 weeks. We follow a phased delivery model with weekly demos.
