Build production-ready blockchain applications with expert architecture and rapid deployment.
We architect and develop complete, secure blockchain solutions tailored to your business logic. Our full-cycle development delivers production-ready applications in 4-8 weeks, from initial concept to mainnet deployment. We specialize in:
Solidity/Rust development with OpenZeppelin security patterns.React/Next.js) integrated with ethers.js/wagmi.The Graph) and secure relayers.We focus on security-first development, with all contracts undergoing rigorous internal audits and formal verification before deployment.
Our process ensures faster time-to-market and reduced technical debt. We provide:
We architect and deploy secure, scalable token-gated payment infrastructure with enterprise-grade reliability. Our solutions are built to handle high transaction volumes while maintaining strict compliance and user privacy.
Custom, gas-optimized smart contracts for payment logic, token gating, and fee distribution. All contracts undergo rigorous security audits following OpenZeppelin standards and are verified on-chain.
Seamless integration with EVM-compatible chains (Ethereum, Polygon, Arbitrum) and Solana. We handle cross-chain settlement and liquidity bridging to maximize user reach and minimize fees.
Automated, configurable rules engine for KYC/AML checks, transaction monitoring, and jurisdictional compliance. Integrates with leading providers for real-time screening.
RESTful and WebSocket APIs with 99.9% uptime SLA, built for developer ease. Includes comprehensive documentation, SDKs, and dedicated technical support.
Flexible rule sets for gating payments based on NFT ownership, token balances, DAO membership, or custom on-chain credentials. Supports dynamic, time-based, and tiered access.
Pre-integrated connections to major regulated fiat gateways (like Stripe, MoonPay) for smooth user onboarding. Handles currency conversion, fraud detection, and settlement reconciliation.
Our token-gated payment gateway delivers measurable results, from accelerated revenue to hardened security. Here's what you can expect when you partner with Chainscore.
Go live with a secure, compliant payment gateway in under 4 weeks, unlocking new token-based revenue streams faster than building in-house. We handle the complex smart contract and compliance logic so you can focus on growth.
Deploy with confidence. Every smart contract powering your gateway undergoes rigorous audits by leading firms like CertiK and Quantstamp, following OpenZeppelin standards to protect user funds and platform integrity.
Support payments in ETH, USDC, and your native token across Ethereum, Polygon, and Arbitrum from day one. Our modular architecture allows for easy addition of new chains and assets as your business expands.
Eliminate the cost and complexity of maintaining payment infrastructure. We provide 24/7 monitoring, automatic compliance updates, and a 99.9% uptime SLA, freeing your team to build core product features.
Built-in tools for KYC/AML checks, transaction monitoring, and regulatory reporting. Our gateway is designed to meet global standards, reducing legal risk and simplifying partnerships with traditional finance.
Handle from 100 to 100,000+ daily transactions without performance degradation. Our system is load-tested and optimized for high-throughput environments typical of successful NFT drops and token launches.

A structured, security-first approach to building and deploying your token-gated payment gateway. We deliver production-ready systems, not just prototypes.
We architect your gateway's core logic with secure, gas-optimized smart contracts. This includes payment routing, token whitelisting, fee management, and compliance hooks using battle-tested patterns from OpenZeppelin and Solidity 0.8+.
Development of a robust backend service to handle transaction orchestration, real-time balance checks, and webhook notifications. We provide a clean REST/GraphQL API for seamless integration with your existing e-commerce or SaaS platform.
Every line of code undergoes rigorous review. Our process includes automated analysis, manual auditing by in-house experts, and optional third-party audits from firms like CertiK or Quantstamp to ensure fund safety and contract integrity.
We deploy a fully functional staging environment on testnets (Sepolia, Mumbai) for comprehensive integration testing. This includes end-to-end payment flows, failure scenario simulations, and load testing under realistic transaction volumes.
Managed deployment to Ethereum, Polygon, or your chosen L2. We implement real-time monitoring with alerts for failed transactions, liquidity thresholds, and security anomalies using tools like Tenderly and OpenZeppelin Defender.
We deliver complete technical documentation, admin guides, and integration SDKs for your engineering team. The process includes knowledge transfer sessions to ensure your team can operate and extend the system independently.
Get clear answers on development timelines, security, and integration for your custom token-gated payment solution.
We deliver a production-ready, audited token-gated payment gateway in 4-8 weeks from kickoff. This includes smart contract development, frontend integration, security audits, and deployment to your chosen mainnet. For standard ERC-20/ERC-721 integrations, delivery is typically on the lower end of that range. Complex logic, multi-chain support, or custom tokenomics may extend the timeline, which we scope and agree upon before project start.
