Anonymous Subscription Billing System

Deploy custom ERC-20/ERC-721 subscription logic with zero-knowledge proofs or stealth addresses. We build contracts that keep payment flows private while maintaining full on-chain verifiability for compliance.

Integrate seamless billing across Ethereum, Polygon, Arbitrum, and Solana. We handle cross-chain settlement and gas abstraction so your users pay with any supported asset on their preferred network.

Gain instant insights into MRR, churn, and customer lifetime value with dashboards that reconcile on-chain events with traditional accounting. Track subscriptions across wallets without compromising privacy.

REST and GraphQL APIs for managing plans, customers, and invoices. Includes webhooks for payment events, failed charge retry logic, and idempotent endpoints for reliable integration.

Automated generation of auditable receipts and tax documents. Our system maintains an immutable record of all billing events, simplifying financial audits and regulatory reporting for Web3 businesses.

Reliable job queues for invoice generation, email notifications, and payment reconciliation. Built on AWS/GCP with auto-scaling to handle millions of subscribers without downtime.

Automated, on-chain settlement eliminates manual reconciliation errors and prevents subscription fraud. Every payment is cryptographically verified and immutably recorded.

Privacy-preserving architecture minimizes KYC/AML data collection and storage requirements, significantly lowering legal and operational costs associated with traditional billing.

Users subscribe with a crypto wallet, not personal data. Remove geographic and identity barriers to instantly capture a global Web3-native audience.

Smart contracts enforce recurring payment logic with automated, fail-safe execution. Eliminate failed payments due to expired cards and ensure consistent revenue.

Transparent, user-controlled subscription management with privacy guarantees builds stronger trust, directly impacting customer lifetime value (LTV) and reducing churn.

Fully managed API and smart contract suite. Integrate a production-ready billing module in weeks, not months, and scale without infrastructure overhead.

We begin with a collaborative 2-week sprint to define your tokenomics, privacy requirements, and system architecture. This includes threat modeling and selecting the optimal privacy stack (e.g., Semaphore, zk-SNARKs).

Our engineers build your core subscription logic using Solidity 0.8+ with OpenZeppelin libraries. We implement gas-optimized recurring billing, proration, and upgradeable proxy patterns from day one.

Every contract undergoes rigorous internal review followed by a formal audit with a top-tier firm like Spearbit or Code4rena. We manage the full audit cycle, from scoping to remediation.

We develop a React/Next.js dashboard for subscription management and a secure, non-custodial checkout widget. Includes API endpoints for CRM, analytics, and payment provider webhooks.

Comprehensive testing across testnets (Sepolia, Base Sepolia) with simulated load and failure scenarios. We handle the mainnet deployment, frontend hosting setup, and DNS configuration.

Receive 30 days of included support with 24/7 system monitoring, performance dashboards, and on-call incident response. We provide documentation and training for your team.
