We deliver production-ready smart contracts for ERC-20, ERC-721, and custom protocols, built on Solidity 0.8+ with OpenZeppelin standards. Our process includes formal verification and gas optimization to ensure cost-efficiency and security from day one.
Bitcoin-Powered Subscription Billing API
Smart Contract Development
Enterprise-grade smart contracts built with security-first development and comprehensive audit support.
- Security Audits: Multi-stage review process culminating in a final audit report from leading security firms.
- Gas Optimization: Achieve up to 40% lower transaction costs through optimized contract logic and storage patterns.
- Upgradeability: Implement secure upgrade paths using
Transparent ProxyorUUPSpatterns for future-proof dApps.
We don't just write code; we engineer resilient systems. Every contract includes comprehensive test suites with >95% coverage and deployment scripts for mainnet and testnets.
Core Features of Your Billing API
Our Bitcoin-powered API delivers the reliability, security, and flexibility required for high-volume, global subscription businesses. Built by engineers for engineers.
Non-Custodial Bitcoin Settlement
Process recurring payments directly on the Bitcoin blockchain via Lightning Network or on-chain. Maintain full control of funds with zero counterparty risk and eliminate traditional payment rails.
Enterprise-Grade Reliability
Built on a globally distributed node infrastructure with automatic failover. Guaranteed uptime for mission-critical billing operations with comprehensive monitoring and alerting.
Flexible Subscription Logic
Support complex billing models: metered usage, tiered pricing, free trials, and prorations. Update plans, add-ons, and coupons via API with real-time invoice generation.
Automated Compliance & Reporting
Handle tax calculation (VAT, GST), generate compliant invoices, and maintain detailed audit trails for every transaction. Simplify financial reconciliation and regulatory reporting.
Bank-Grade Security
SOC 2 Type II compliant infrastructure. All data encrypted in transit (TLS 1.3+) and at rest (AES-256). Regular third-party security audits and penetration testing.
Why Build Your Subscription Engine with Us
We deliver a production-ready Bitcoin subscription API, so your engineering team can focus on core product innovation instead of building and securing complex payment infrastructure.
Enterprise-Grade Security & Compliance
Our infrastructure is built on battle-tested Bitcoin protocols (Lightning, Taproot) with SOC 2 Type II compliance and regular third-party audits. We manage key custody and transaction security so you don't have to.
Faster Time-to-Market
Go from concept to live subscription service in weeks, not months. Our pre-built API endpoints, SDKs, and developer dashboard handle invoicing, dunning, and customer management out of the box.
Proven Bitcoin & Lightning Expertise
Built by engineers who have processed over $50M+ in on-chain and Lightning transactions. We provide deep protocol expertise for PSBTs, multi-sig, and Taproot to ensure reliability and low fees.
Scalable & Cost-Effective Infrastructure
Eliminate the overhead of managing node infrastructure, channel liquidity, and on-chain fee estimation. Our platform scales automatically with your user growth, with predictable, transparent pricing.

Build vs. Buy vs. Chainscore
Choosing the right foundation for your Bitcoin-powered recurring billing is critical. Compare the time, cost, and risk of building from scratch, using a generic off-the-shelf API, or partnering with Chainscore for a purpose-built solution.
| Key Factor | Build In-House | Generic Billing API | Chainscore |
|---|---|---|---|
Time to Live Product | 6-12+ months | 4-8 weeks | 2-4 weeks |
Core Bitcoin Integration | Custom Dev | Basic UTXO/Witness | Optimized PSBT & Taproot |
Recurring Payment Logic | Your Code | Limited Templates | Flexible Smart Contracts |
Security & Audit Status | High Risk (Unaudited) | Shared Risk (Black Box) | Low Risk (Audited & Open Source) |
Compliance (KYC/AML) | Your Responsibility | Basic Checks | Integrated On-Chain Flow |
Ongoing Protocol Updates | Your Team | Vendor Schedule | Proactive Upgrades |

Our Development Process
We follow a structured, milestone-driven approach to deliver your Bitcoin-powered billing API with clarity, speed, and enterprise-grade security.
Discovery & Architecture
We analyze your business model to design a tailored Bitcoin payment flow, integrating with your existing stack. We define the optimal UTXO management strategy and API specifications.
Core API & Smart Contract Development
We build the core subscription logic using Rust (for L1/L2) or Solidity (for EVM sidechains), implementing automated invoicing, proration, and secure key management.
Security Audit & Testing
Every line of code undergoes rigorous internal review and automated testing. We simulate attack vectors on payment flows and UTXO handling before deployment.
Staging & Integration
We deploy to a testnet environment (Signet/Testnet) and provide a complete SDK for your team. We conduct end-to-end integration testing with your frontend.
Mainnet Deployment & Monitoring
We manage the secure mainnet deployment with you. We provide 24/7 monitoring dashboards for transaction success rates, fee optimization, and system health.
Ongoing Support & Scaling
We offer ongoing maintenance, protocol upgrade management, and scaling consultations. We help you optimize for volume and integrate new Bitcoin Layer 2 solutions.
Frequently Asked Questions
