Subscription Model Smart Contracts for DePIN & IoT

Implement any subscription model—flat-rate, tiered, usage-based, or hybrid—with configurable billing cycles (daily, weekly, monthly, annual). Supports proration, trials, and grace periods.

Secure, non-custodial payment flows with automatic charge execution. Features include off-chain signature verification for gasless approvals and failed payment handling with dunning logic.

Minimize user transaction costs with efficient storage patterns and batch operations. Achieve up to 40% gas savings compared to naive implementations for common subscription actions.

Granular, role-based permissions (Owner, Admin, Treasurer) managed via multi-sig or DAO governance. Enables secure team management and treasury operations.

Built-in event emission for all key actions (subscription, renewal, cancellation). Integrate seamlessly with your dashboard or CRM via configurable webhook endpoints.

Transform one-time hardware sales into recurring revenue streams. Our smart contracts automate billing cycles, usage tracking, and payment collection for connected devices, ensuring consistent cash flow.

Eliminate manual invoicing, payment chasing, and reconciliation. Smart contracts handle subscription logic, proration, and renewals, freeing your team to focus on product development.

Build trust with immutable, transparent billing. Customers can independently verify usage data and payment terms on-chain, reducing disputes and support tickets.

Easily deploy and manage complex pricing models—pay-per-use, tiered access, feature gating—across millions of devices without backend changes.

Contracts are built with security-first principles, audited against common vulnerabilities, and designed to facilitate regulatory compliance for data usage and billing.

Leverage our battle-tested, modular smart contract architecture for IoT subscriptions. Go from concept to live deployment in weeks, not months.

We architect for minimal gas consumption using techniques like state variable packing, efficient data structures, and batch operations, reducing user transaction costs by up to 40%.

Contracts are designed for portability across EVM-compatible chains (Ethereum, Polygon, Arbitrum, Base). We handle the configuration and verification for your target network.

Every contract is backed by unit tests (Hardhat/Foundry), integration tests, and scenario-based simulations, achieving >95% branch coverage before audit.
