We architect and deploy custom smart contracts that form the immutable backbone of your application. Our development process is built on security-first principles, utilizing OpenZeppelin libraries and Solidity 0.8+ best practices to mitigate risks before the first line of code is written.
StarkNet & ZK-Rollup Payment Infrastructure
Smart Contract Development
Secure, production-ready smart contracts built for your specific business logic and audited for enterprise deployment.
From tokenomics to complex DeFi logic, we translate your requirements into gas-efficient, upgradeable, and secure on-chain systems.
- End-to-End Development: Full lifecycle support from design and
Hardhat/Foundrytesting to mainnet deployment and verification. - Security Audits: Every contract undergoes internal and third-party review to identify vulnerabilities, with a focus on common attack vectors like reentrancy and oracle manipulation.
- Protocol-Specific Expertise: Custom implementations for
ERC-20,ERC-721,ERC-1155, staking mechanisms, automated market makers (AMMs), and governance modules.
Core Technical Capabilities We Deliver
We architect and deploy high-throughput, secure payment systems on StarkNet, delivering production-ready infrastructure that scales with your business.
StarkNet Smart Contract Development
Cairo-based smart contracts for payment logic, escrow, and multi-signature wallets. Built with OpenZeppelin Cairo libraries and gas-optimized for L2 efficiency.
ZK-Rollup Payment Gateway
End-to-end payment processing with sub-second finality. Includes deposit/withdrawal bridges, fee abstraction, and real-time transaction status APIs.
Enterprise-Grade Security & Audits
Comprehensive security review from protocol design to deployment. Includes formal verification of critical Cairo contracts and penetration testing.
Scalable Infrastructure Orchestration
Managed node infrastructure (Sequencer, Prover) with auto-scaling, multi-region deployment, and 99.9% uptime SLA for mission-critical payment systems.
Custom Payment Logic & Compliance
Implement complex business rules: recurring payments, conditional releases, and regulatory-compliant transaction monitoring (AML/KYC) hooks.
Business Outcomes for Your Game or Metaverse
Our StarkNet payment infrastructure delivers measurable results, from accelerated revenue to enhanced player retention. Here’s what you can expect.
Frictionless Onboarding & Payments
Integrate a seamless, custodial wallet experience with one-click transactions. Reduce player drop-off by up to 70% compared to traditional Web3 onboarding flows.
Provably Fair & Transparent Economies
Leverage ZK-Rollup technology for instant, verifiable settlement of in-game asset trades and marketplace transactions. Build immutable trust with your player base.
Scalable Microtransaction Revenue
Enable high-volume, low-value transactions with near-zero fees. Monetize gameplay actions previously cost-prohibitive on Ethereum L1, unlocking new revenue streams.
Interoperable Asset Portability
Design assets that move seamlessly between games and virtual worlds using StarkNet's L2 native composability. Increase asset utility and long-term holder value.
Reduced Time-to-Market
Go live in weeks, not months. Our pre-built, modular payment rails and developer tooling accelerate integration, letting you focus on core gameplay and UX.

Our Delivery Methodology
We deliver production-ready StarkNet payment systems using a structured, milestone-driven process that de-risks development and accelerates your time-to-market.
Architecture & Design Sprint
We begin with a collaborative workshop to define your payment flow, token standards (ERC-20, ERC-721), and system architecture. This ensures the technical blueprint aligns with your business logic and scalability requirements.
Smart Contract Development
Our Cairo developers build your core payment contracts using OpenZeppelin libraries and established security patterns. Every contract is modular, gas-optimized, and includes comprehensive unit tests.
Security & Audit Integration
We integrate security from day one. All contracts undergo internal review and are prepared for formal audits by leading firms like Nethermind or ABDK, with remediation handled by our team.
Testnet Deployment & Staging
We deploy the full system to StarkNet testnet (goerli) for integration testing. This phase includes stress testing, frontend-backend integration, and user acceptance testing (UAT) with your team.
Mainnet Launch & Monitoring
We manage the secure mainnet deployment and establish real-time monitoring for transaction success rates, contract events, and system health using tools like Tenderly and Chainscore's own analytics.
Documentation & Handover
We deliver complete technical documentation, admin guides, and operational runbooks. The final handover includes a knowledge transfer session to empower your engineering team for long-term ownership.
Build vs. Buy: Custom ZK-Rollup vs. Generic Payment Solutions
A technical and economic comparison of developing a custom StarkNet-based payment rollup in-house versus leveraging Chainscore's managed infrastructure.

Frequently Asked Questions
Get clear answers on timelines, costs, and technical details for your payment infrastructure project.
A standard StarkNet payment infrastructure deployment takes 2-4 weeks from kickoff to mainnet launch. This includes smart contract development, Cairo integration, frontend/backend connectors, and initial testing. Complex protocols with custom ZK-circuits or multi-chain bridges can extend to 6-8 weeks. We provide a detailed sprint-by-sprint timeline during the discovery phase.
