The Infrastructure Decision Matrix
Build In-House vs. Use Chainscore's Universal Wallet API
A technical and financial comparison for CTOs and engineering leads evaluating wallet infrastructure. We quantify the hidden costs and risks of custom development versus a managed API.
| Key Factor | Build In-House Wallet Stack | Chainscore Universal Wallet API |
|---|---|---|
Time to Production Launch | 6-12+ months | 2-4 weeks |
Initial Engineering Cost | $250K - $500K+ | $0 (No upfront dev cost) |
Annual Maintenance & DevOps | $150K - $300K (2-3 FTEs) | From $60K/year (Managed SLA) |
Security & Audit Overhead | High (Unaudited code, key management risk) | Enterprise-grade (SOC 2, MPC, regular audits) |
Multi-Chain Support (EVM, Solana, etc.) | Per-chain integration (months each) | Unified API (All major chains included) |
Feature Set (Gas Sponsorship, Batch TX, SIWE) | Custom development per feature | Production-ready out-of-the-box |
Uptime & Reliability SLA | Your team's responsibility (typical 99%) | 99.9% Guaranteed with 24/7 monitoring |
Scalability & Peak Load Handling | Requires capacity planning & scaling | Automatically scales to 10,000+ TPS |
Compliance & Regulatory Tools | Build from scratch (KYC, Travel Rule) | Integrated compliance modules available |
Future-Proofing (New L2s, Protocols) | Continuous integration burden | Automatic protocol updates included |

CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
We architect and deploy custom smart contracts that are secure, gas-optimized, and tailored to your tokenomics. Our development process is built on audited standards and battle-tested patterns from OpenZeppelin and Solmate.
- Token Systems:
ERC-20,ERC-721,ERC-1155, and custom multi-token architectures. - DeFi Protocols: Automated Market Makers (AMMs), staking pools, and yield strategies.
- Governance & DAOs: Voting mechanisms, treasury management, and proposal systems.
- Enterprise Logic: Custom business rules, access control, and multi-sig integrations.
We deliver a fully tested, documented, and deployable contract suite in 2-4 weeks, complete with a security review to mitigate costly vulnerabilities before mainnet launch.

Frequently Asked Questions
Get specific answers about our wallet infrastructure service, from deployment timelines to security and support.
Our Universal Wallet API is a unified infrastructure layer that abstracts away the complexity of multi-chain wallet management. It provides a single RESTful interface for core wallet operations—key generation, transaction signing, balance queries, and gas estimation—across EVM chains (Ethereum, Polygon, Arbitrum), Solana, and other L2s. Instead of building and maintaining separate RPC integrations for each chain, your application interacts with our API, which handles protocol-specific logic, nonce management, and fee optimization, reducing your development time by 70%.
