We architect, develop, and deploy custom Solidity/Rust smart contracts that are secure by design. Every contract undergoes a multi-layered audit process, including automated analysis and manual review, before deployment to mainnet.

CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built to your exact specifications.
Deliver a fully audited, gas-optimized contract suite in 2-4 weeks, from specification to production readiness.
Our development process is built for reliability:
- Formal Specification: We define logic, roles, and upgrade paths upfront.
- Modular Security: Built with
OpenZeppelinstandards and custom security patterns. - Comprehensive Testing: Unit, integration, and scenario testing with 95%+ coverage.
- Deployment & Verification: Full support for deployment, Etherscan verification, and initial configuration.
We specialize in complex DeFi primitives, NFT ecosystems, and cross-chain applications. Whether you need a novel AMM, a staking vault, or a dynamic NFT collection, we deliver battle-tested code that performs under mainnet conditions.

PROVEN METHODOLOGY
Our Migration Framework
A structured, four-phase approach to migrate your legacy API gateway to a modern, scalable Web3 infrastructure with zero downtime and full data integrity.
01
Discovery & Architecture Audit
We conduct a comprehensive analysis of your existing API gateway, smart contracts, and backend systems to map dependencies, identify risks, and design a target architecture optimized for Web3 performance and security.

02
Zero-Downtime Migration Strategy
Implement a phased cutover using canary deployments and traffic shadowing. We ensure your existing services remain fully operational while the new gateway is validated, eliminating business disruption.

03
Smart Contract & Data Layer Integration
Seamlessly connect your new API gateway to on-chain data (EVM, Solana) and off-chain oracles. We handle state synchronization, event listening, and secure signing mechanisms for end-to-end functionality.

The Technical & Business Case for Migration
Legacy vs. Modernized API Architecture
A direct comparison of traditional, monolithic API gateways versus a modern, decentralized architecture built for Web3 scale and security.
| Architecture Feature | Legacy Monolithic Gateway | Modernized Decentralized Gateway |
|---|---|---|
Deployment Model | Centralized, Single Point of Failure | Decentralized, Fault-Tolerant |
Scalability Limit | Vertical Scaling (Costly Hardware) | Horizontal, Elastic Scaling |
Latency for Global Users | High (100-300ms+), Depends on Location | Low (<50ms), Edge-Optimized |
Security Model | Perimeter-Based (Firewall/VPN) | Zero-Trust, Identity-Aware |
Protocol Support | REST, GraphQL, SOAP | REST, GraphQL, gRPC, Web3 JSON-RPC |
Developer Experience | Complex Configuration, Long Dev Cycles | Declarative APIs, Self-Service Portal |
Time to Add New Endpoint | 2-4 Weeks (IT Ticket Cycle) | < 1 Day (Developer Self-Service) |
Annual Infrastructure & Ops Cost | $150K - $500K+ | $50K - $150K |
Resilience to DDoS Attacks | Vulnerable, Requires Expensive Mitigation | Inherently Resistant via Decentralization |

Our Engagement Process
We follow a structured, four-phase methodology to ensure your API Gateway migration is seamless, secure, and delivers immediate operational value. From initial assessment to final handover, our process is designed for transparency and predictable outcomes.
01
Discovery & Architecture Review
We conduct a comprehensive audit of your existing API infrastructure, smart contracts, and traffic patterns. This phase delivers a detailed migration roadmap with risk assessment, cost projections, and a target architecture blueprint for Chainscore's gateway.

Frequently Asked Questions
Common questions about our structured consulting process for migrating your Web3 infrastructure to a dedicated API gateway.
A standard migration from a public RPC provider to a dedicated gateway takes 2-4 weeks. This includes discovery, architecture design, deployment, testing, and cutover. Complex multi-chain deployments or custom indexing requirements can extend this to 6-8 weeks. We provide a detailed project plan within the first week of engagement.
