The Strategic Choice for Your Engineering Team
Build vs. Buy: The Multi-Chain Wallet Integration Dilemma
Compare the total cost, risk, and time investment of developing a custom multi-chain wallet connector versus integrating Chainscore's production-ready SDK.
| Key Factor | Build In-House | Buy with Chainscore SDK |
|---|---|---|
Time to Market (Initial Integration) | 4-9 months | 2-4 weeks |
Initial Development Cost | $150K - $400K+ | $25K - $75K |
Supported Chains (EVM & Non-EVM) | Requires per-chain R&D | 20+ chains out-of-the-box |
Security & Audit Overhead | High (unaudited, custom code) | Low (pre-audited, battle-tested) |
Ongoing Maintenance & Updates | Dedicated 2-3 engineer team | Handled by Chainscore |
New Chain Integration Lead Time | 1-2 months per chain | < 1 week per chain |
Wallet Provider Coverage | Manual integration per wallet | Unified API for 100+ wallets |
Total Cost of Ownership (Year 1) | $300K - $700K+ | $50K - $150K |
Guaranteed Uptime SLA | Your infrastructure's risk | 99.9% SLA with monitoring |
Expert Support & Incident Response | Internal team only | 24/7 engineering support available |

PREDICTABLE, TRANSPARENT, AND SECURE
Our Delivery Process
From initial consultation to production deployment, our structured 4-phase process ensures your multi-chain wallet integration is delivered on time, within scope, and to the highest security standards.
01
Discovery & Architecture
We conduct a deep technical analysis of your application's needs, target chains (EVM, Solana, Cosmos, etc.), and user flows. You receive a detailed technical specification and architecture plan, ensuring alignment before a single line of code is written.

CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by experts for your Web3 application.
We architect, develop, and audit custom Solidity/Rust smart contracts that form the immutable backbone of your dApp. Our development process ensures gas-optimized code, adherence to EIP standards, and comprehensive security from day one.
- End-to-End Development: From initial design and
OpenZeppelinintegration to deployment and verification on-chain. - Security-First Approach: Every line undergoes internal review against common vulnerabilities before formal audit.
- Protocol-Specific Logic: Custom implementations for DeFi (AMMs, lending), NFTs (dynamic metadata, staking), and DAOs.
Move from concept to a live, audited mainnet contract in as little as 4 weeks with a fixed-scope engagement.
We deliver battle-tested contracts with:
- Full test suite (95%+ coverage) and deployment scripts.
- Technical documentation and developer guides.
- Post-deployment support for upgrades and maintenance.

Frequently Asked Questions
Get clear answers on timelines, security, and support for our enterprise-grade SDK.
A standard integration takes 2-4 weeks from kickoff to production deployment. This includes initial setup, core wallet connection features, and basic transaction flows. Complex requirements like custom UI/UX, advanced security modules, or support for 10+ additional blockchains can extend the timeline, which we scope and quote for upfront.
