Build vs. Buy: ZK-Rollup vs. Traditional Settlement
A detailed comparison of the cost, time, and risk profile for developing a high-throughput bulk payment processor in-house versus leveraging Chainscore's production-ready ZK-Rollup solution.
| Key Factor | Build In-House ZK-Rollup | Use Chainscore Solution | Traditional Settlement (L1) |
|---|---|---|---|
Time to Production | 6-12+ months | 4-8 weeks | N/A (Existing) |
Upfront Development Cost | $300K - $750K+ | $50K - $150K | $0 |
Annual Maintenance & Ops Cost | $150K - $300K | Optional SLA from $30K/year | Variable Gas Costs |
Security Audit Requirement | High (Critical) | Included (Pre-audited) | N/A (Relies on Base Layer) |
Peak Transaction Throughput | Theoretical 10k+ TPS | Guaranteed 10k+ TPS | < 100 TPS |
Settlement Finality | Custom (Your Risk) | < 2 seconds (SLA) | ~12 minutes (Ethereum) |
Team Expertise Required | ZK-Circuit, Solidity, DevOps | Integration & API | Solidity, Web3.js |
Recurring Infrastructure Risk | Your responsibility | Managed by Chainscore | Base Layer Risk |

CLIENT-CENTRIC DELIVERY
Our Development & Delivery Process
A transparent, phased approach designed to deliver a production-ready ZK-Rollup payment processor on time and within budget, minimizing your technical risk.
01
Discovery & Architecture Design
We conduct a deep-dive workshop to define your specific payment flows, volume requirements, and compliance needs. We then architect the optimal ZK-Rollup solution (zkSync, Starknet, Polygon zkEVM) and smart contract framework.
1-2 weeks
Phase Duration
