EVM Subscription Smart Contract Development

Built with Solidity 0.8+ and OpenZeppelin libraries, our contracts minimize transaction costs for end-users. We implement efficient state management and batch processing to reduce recurring billing gas fees by up to 40%.

Support for fixed, usage-based, and tiered subscription models with configurable billing cycles (daily, weekly, monthly, annual). Includes proration, free trials, and grace periods for failed payments.

Non-custodial architecture where funds are held in escrow smart contracts. Implements secure pull-payment patterns to prevent reentrancy and front-running attacks, with optional integration for stablecoin or native token payments.

Full automation for subscription states: active, past-due, canceled, and expired. Includes automated dunning management for failed charges and configurable cancellation policies.

Granular, role-based permissions using OpenZeppelin's AccessControl. Separate roles for administrators, billing managers, and customer support to ensure secure and compliant operations.

Emit standardized Ethereum events for all key actions (subscription created, renewed, canceled). Enables easy off-chain indexing for dashboards, analytics, and customer notifications.

Deploy subscription logic that has processed $100M+ in recurring payments across live networks. Our modular contracts are built on proven patterns from our own SaaS platform.

Every contract undergoes rigorous audits using OpenZeppelin standards and formal verification tools. We implement multi-sig treasury management and comprehensive pause/upgrade mechanisms.

Our subscription logic is engineered for minimal gas consumption, reducing user transaction costs by up to 40% compared to naive implementations, critical for high-frequency billing cycles.

Support fixed-rate, usage-based, tiered, and hybrid billing—all within a single contract suite. Easily integrate with any ERC-20 token or native currency.

Get from specification to mainnet in under 3 weeks. We provide comprehensive documentation, integration SDKs, and dedicated technical support for your engineering team.

Built-in tools for revenue reporting, subscriber analytics, and audit trails. Generate real-time insights into MRR, churn, and lifetime value directly from the blockchain.

We start with a deep technical workshop to define your business logic, tokenomics, and integration requirements. We deliver a detailed technical specification and architecture diagram for your review.

Our senior Solidity engineers build your contracts using OpenZeppelin libraries and established security patterns. Development includes comprehensive unit and integration testing with Hardhat/Foundry.

Every contract undergoes an internal audit against our 150+ point security checklist. We prepare a formal audit report and fix all critical/high issues before proceeding to external review.

We handle the secure mainnet deployment with multi-sig configuration. Post-launch, we provide 30 days of proactive monitoring with alerting for any anomalous contract activity.

We deliver complete technical documentation, admin guides, and integration SDKs. A final handover session ensures your team is fully equipped to manage and extend the system.
