EVM Smart Subscription Engine Development

Deploy a production-ready, audited subscription engine in under 3 weeks, not months. We provide a modular framework with pre-built logic for trials, billing cycles, and upgrades, so you can launch faster and capture market share.

Engineered with gas-optimized Solidity patterns and state management to minimize transaction fees for you and your users. Achieve up to 40% lower gas consumption on recurring billing operations compared to naive implementations.

Every contract undergoes rigorous audits following OpenZeppelin standards. We implement secure upgrade patterns, role-based access control, and compliance-ready features for KYC/gated subscriptions, protecting your revenue and users.

Reduce failed payments and churn with robust dunning logic, flexible payment token support, and automated lifecycle management. Our engines are designed to maximize LTV (Lifetime Value) and minimize involuntary churn.

Build once, deploy everywhere. Our engine is designed for seamless operation across Ethereum, Polygon, Arbitrum, and other EVM chains, ensuring your subscription service scales with your user base without re-engineering.

Get comprehensive documentation, admin dashboards, and integration SDKs. Your team spends less time maintaining custom billing logic and more time building core product features, accelerating your development cycles.

We begin with a deep dive into your business logic to architect a tailored subscription model (recurring, usage-based, tiered). This phase includes token standard selection (ERC-20, ERC-777), gas optimization strategy, and a detailed technical specification.

Our engineers write clean, modular Solidity (0.8+) code using OpenZeppelin libraries. We implement core features: automated billing cycles, proration logic, upgradeable proxy patterns, and multi-chain compatibility from day one.

Every line of code undergoes rigorous unit, integration, and scenario testing. We conduct internal audits and facilitate third-party reviews with firms like CertiK or Quantstamp before mainnet deployment.

We handle the secure deployment to your chosen EVM network (Ethereum, Polygon, Arbitrum, etc.) and integrate the engine with your front-end dApp and backend systems via comprehensive APIs and event listeners.

Post-launch, we provide real-time dashboards for subscription metrics, failed payment alerts, and gas consumption. We offer ongoing support for upgrades, feature additions, and performance tuning.

You receive complete technical documentation, admin guides, and integration SDKs. We ensure your team is fully equipped to manage and extend the system, with optional retainer support available.

Native support for stablecoin (ERC-20) and NFT (ERC-721/1155) payments. We handle complex logic for multi-currency billing, proration, and NFT-gated subscription tiers, enabling flexible monetization models.

Contracts are written in Solidity 0.8.x+ using OpenZeppelin libraries and audited patterns. We focus on minimizing gas costs for recurring operations, reducing your operational expenses and user fees.

Architected for deployment across EVM-compatible chains (Ethereum, Polygon, Arbitrum, Base). We ensure consistent logic and security postures, allowing you to capture users across ecosystems.

All core contracts undergo rigorous internal review and are prepared for third-party audits by firms like Spearbit or Code4rena. We implement comprehensive test suites with >95% coverage.
