CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3-native engineers.
From a 2-week MVP to a full protocol suite, we ensure your contracts are secure, gas-optimized, and ready for mainnet.
- Token Systems: Custom
ERC-20,ERC-721, andERC-1155implementations with advanced features like vesting and governance. - DeFi Logic: Automated Market Makers (AMMs), lending/borrowing pools, and staking mechanisms.
- Security First: Every contract includes comprehensive unit tests and receives a formal verification report.

THE STRATEGIC APPROACH
Why Start with a Proof-of-Concept
A focused PoC de-risks your MPC wallet development, validates core assumptions with real data, and secures stakeholder buy-in before committing significant engineering resources.
01
De-Risk Technical Feasibility
Validate your core architecture—key generation, signing flows, and multi-chain support—on a testnet before full-scale development. We identify and resolve integration hurdles early.
> 90%
Reduction in post-launch critical bugs
2-4 weeks
To validate core logic
02
Secure Stakeholder & Investor Buy-In
Transform abstract concepts into a functional demo. A tangible PoC demonstrates progress, clarifies the product vision, and is instrumental for securing the next funding round.
70% faster
Internal approval cycles

Demo for investor pitches
03
Validate Product-Market Fit
Test critical user assumptions—recovery flows, transaction bundling, fee management—with a closed user group. Gather actionable feedback to refine the roadmap before public launch.

Strategic Investment Analysis
PoC vs. Full Build: Making the Strategic Choice
Compare the scope, investment, and outcomes of a targeted Proof-of-Concept versus a production-ready MPC wallet build. Choose the right path to validate your concept or launch with confidence.
| Key Factor | Proof-of-Concept (PoC) | Full Production Build |
|---|---|---|
Primary Goal | Validate core technical feasibility & user flow | Launch a secure, scalable, market-ready product |
Development Timeline | 2-4 weeks | 8-16 weeks |
Core Deliverables | 1-2 key wallet functions (e.g., create, sign) on testnet | Full-featured MPC wallet with UI/UX, admin dashboard, multi-chain support |
Security Posture | Basic security review & best practices | Comprehensive audit by a top-tier firm (e.g., Quantstamp, CertiK), penetration testing |
Infrastructure | Single cloud provider, testnet only | Multi-region deployment, mainnet-ready, disaster recovery |
Team Involvement | 1-2 Chainscore engineers | Dedicated pod: Lead Architect, 2-3 Engineers, DevOps, QA |
Total Cost Estimate | $15K - $30K | $80K - $200K+ |
Best For | Seed-stage startups securing funding, testing a novel use case | Series A+ companies, regulated entities (VASPs), high-volume applications |
