Build vs. Buy: PayJoin Integration Analysis
A detailed comparison of the time, cost, and risk involved in developing a PayJoin solution in-house versus partnering with Chainscore for a production-ready implementation.
| Key Factor | Build In-House | Chainscore Implementation |
|---|---|---|
Time to Production | 6-12 months | 4-8 weeks |
Initial Development Cost | $200K - $500K+ | $50K - $150K |
Security Audit Requirement | High (External audit required) | Included (Pre-audited modules) |
Protocol Expertise (BIP78, PSBT) | Must hire/develop | Included (Core competency) |
Ongoing Maintenance & Updates | Your engineering team | Managed service with optional SLA |
Integration Complexity | High (Wallet, node, backend) | Low (API/SDK-based) |
Compliance & Privacy Safeguards | Your legal team's responsibility | Built-in privacy by design |
Time to First Transaction | Months | Days after integration |
Total Cost of Ownership (Year 1) | $300K - $600K+ | $75K - $200K |

PROVEN FRAMEWORK
Our Implementation Methodology
A structured, four-phase approach designed for institutional clients. We deliver secure, compliant, and production-ready PayJoin infrastructure with predictable timelines and zero operational surprises.
01
Discovery & Architecture Design
We conduct a technical deep-dive to map your existing payment flows, define UTXO management strategies, and architect a custom PayJoin solution. This phase establishes clear requirements, security parameters, and a detailed implementation roadmap.

Frequently Asked Questions
Get clear answers on our process, security, and outcomes for enterprise-grade Bitcoin transaction privacy.
A standard implementation for a single application or wallet integration takes 2-4 weeks from kickoff to production deployment. This includes design, development, integration testing, and security review. Complex, multi-application deployments across an enterprise stack may extend to 6-8 weeks. We provide a detailed project plan with milestones during the initial scoping call.
