Smart Contract Security | High Risk (Requires external audit) | Low Risk (Pre-audited, battle-tested) |
Ongoing Maintenance & Updates | Full-stack team required | Handled by Chainscore |
Multi-Chain Support (EVM) | Custom integration per chain | Built-in for 10+ chains |
Compliance & Tax Logic | Custom, complex implementation | Pre-built modules (1099, VAT) |
Infrastructure Uptime SLA | Your responsibility | 99.9% Guaranteed |
Total Cost of Ownership (Year 1) | $200K - $500K+ | $50K - $150K |
Our Delivery Process: From Integration to Launch
We provide a structured, milestone-driven approach to integrate our Recurring Crypto Subscription SDK into your mobile app, ensuring a smooth path from technical discovery to live production.
Discovery & Architecture Review
We conduct a 2-hour technical deep-dive to analyze your app's architecture, define integration scope, and establish success metrics for your subscription flows.
SDK Integration & Sandbox Testing
Our engineers deliver a pre-configured SDK package with comprehensive documentation. You'll test in a sandbox environment with simulated payment flows and webhooks.
Security Audit & Compliance Setup
We configure multi-sig wallets, establish automated on-chain monitoring with Chainscore, and implement SOC 2-compliant key management for your production environment.
Staging Deployment & Client QA
Deploy the fully integrated SDK to your staging environment. We provide support for your QA team to validate end-to-end subscription creation, renewal, and cancellation.
Production Launch & Go-Live Support
We manage the production deployment, including mainnet wallet funding and final configuration. Our team provides live monitoring support for the first 72 hours post-launch.
Ongoing Optimization & Analytics
Gain access to the Chainscore dashboard for real-time analytics on subscription metrics, revenue, and churn. We schedule quarterly reviews for gas optimization and feature updates.
Smart Contract Development
Secure, production-ready smart contracts built by Web3 experts to power your protocol.
We architect and deploy custom smart contracts that are secure, gas-optimized, and ready for mainnet. Our team specializes in Solidity and Vyper, implementing battle-tested patterns from OpenZeppelin and rigorous security audits. Deliverables include full test suites, deployment scripts, and comprehensive documentation.
- Token Standards: Custom
ERC-20,ERC-721,ERC-1155, andERC-4626vaults. - DeFi Primitives: Automated Market Makers (AMMs), lending pools, staking contracts, and governance modules.
- Enterprise Logic: Multi-signature wallets, vesting schedules, and upgradeable proxy patterns.
- Security First: Every contract undergoes internal review and is prepared for third-party audits.
