AppChain Customization for Institutional Payments

We design and deploy application-specific blockchains with custom consensus, privacy, and compliance modules to meet the stringent requirements of institutional payment and remittance networks.
Chainscore © 2026
overview
CORE SERVICE

Smart Contract Development

Secure, production-ready smart contracts built by Web3-native engineers.

We architect, develop, and audit custom Solidity and Rust smart contracts for DeFi, NFTs, and enterprise applications. Our contracts are built on OpenZeppelin standards and include formal verification for critical logic.

  • Security-First Development: Every contract undergoes internal review and automated analysis before deployment.
  • Gas Optimization: We achieve up to 40% gas savings through efficient data structures and opcode-level tuning.
  • Full Lifecycle Support: From initial design and testing to mainnet deployment and upgrade management via Transparent Proxies.

Deliver a secure, auditable, and maintainable codebase that forms the trusted foundation of your on-chain application.

PREDICTABLE, AUDITABLE, AND SECURE

Our Delivery Process: From Specification to Mainnet

A structured, phased approach designed for institutional clients. We deliver a production-ready, compliant AppChain for payments in 8-12 weeks with full transparency at every milestone.

01

Phase 1: Discovery & Architecture

We conduct a 2-week technical deep-dive to define your payment flows, compliance requirements, and integration points. Deliverables include a detailed technical specification, tokenomics model, and a high-level architecture diagram.
