CORE SERVICE
Smart Contract Development
Secure, gas-optimized smart contracts built to your exact specifications.
From token standards to complex DeFi logic, we deliver contracts that perform as intended under real-world conditions.
- Custom Logic: Tailored
Solidity/Vypercontracts for tokens (ERC-20,ERC-721), DeFi protocols, DAOs, and more. - Security First: Development follows OpenZeppelin standards and includes audits with tools like Slither and MythX.
- Gas Optimization: Every line of code is reviewed to minimize transaction costs for your users.
- Full Lifecycle: We handle deployment, verification on block explorers, and provide upgradeability patterns.

A STRUCTURED, LOW-RISK APPROACH
Our Migration Process: From Analysis to Live Deployment
We de-risk your transition with a proven, four-phase methodology. Each step is designed to ensure data integrity, security, and business continuity, delivering a production-ready system on time and on budget.
01
Phase 1: Discovery & Architecture
We conduct a comprehensive audit of your existing invoice data, workflows, and compliance requirements. This phase defines the target blockchain architecture (e.g., EVM-compatible L2, private consortium) and maps the migration logic.
Client Value: A clear, actionable blueprint and technical specification that aligns all stakeholders and prevents costly mid-project changes.

Phase 2: Smart Contract Development & Testing
Our engineers build the core invoice logic—issuance, payment tracking, reconciliation, and dispute resolution—into secure, gas-optimized smart contracts. Every contract undergoes unit, integration, and security testing.
Client Value: A battle-tested, auditable financial engine that automates trust and eliminates manual reconciliation errors.

Phase 3: Data Migration & Integration
We execute the secure, validated migration of historical invoice data onto the new blockchain ledger. Simultaneously, we build and test API bridges to your existing ERP, accounting, or CRM systems for seamless two-way data flow.
Client Value: Zero data loss, preserved audit trails, and uninterrupted operations for your finance and sales teams.

The Infrastructure Upgrade
Legacy ERP vs. Blockchain-Powered Invoicing
A direct comparison of capabilities, costs, and operational impact when migrating from traditional systems to a custom blockchain solution.
| Capability | Legacy ERP System | Chainscore Migration |
|---|---|---|
Data Reconciliation | Manual, error-prone | Automated, cryptographically verified |
Settlement Finality | 3-5 business days | < 2 seconds |
Audit Trail | Centralized, mutable logs | Immutable on-chain record |
Fraud Prevention | Reactive, rule-based | Proactive, smart contract logic |
Integration Cost (Year 1) | $200K+ in dev hours | $75K-$150K flat project fee |
Time to Deploy New Feature | 6-12 months | 4-8 weeks |
Interoperability | Closed system, APIs | Native cross-chain composability |
Ongoing Maintenance | High (vendor + internal IT) | Optional SLA from $25K/year |

Frequently Asked Questions
Get clear answers on timelines, costs, security, and process for migrating your invoicing to blockchain.
A standard migration for a mid-sized enterprise takes 4-8 weeks from kickoff to production launch. This includes 1-2 weeks for system analysis and smart contract design, 2-4 weeks for development and integration, and 1-2 weeks for testing, security audit, and deployment. Complex systems with multiple ERP integrations may extend to 12 weeks. We provide a detailed project plan within the first week of engagement.
