The Strategic Decision for Your Web3 Product
Build vs. Buy: Paymaster Infrastructure
Choosing between building a paymaster in-house or using a managed service impacts your time-to-market, security posture, and total cost of ownership. This comparison outlines the key factors for technical leaders.
| Factor | Build In-House | Chainscore Paymaster as a Service |
|---|---|---|
Time to Market | 4-9 months for dev, audit & deployment | 2-4 weeks for integration |
Initial Development Cost | $120K - $300K+ (2-3 senior devs) | $0 (No upfront dev cost) |
Security & Audit Overhead | High (Requires independent audit, ~$30K-$80K) | Low (Pre-audited, enterprise-grade contracts) |
Ongoing Maintenance & DevOps | Full-time DevOps/SRE team required | Fully managed 24/7 infrastructure |
Gas Abstraction Features | Basic (ERC-20, flat rate) | Advanced (ERC-20, ERC-721, dynamic pricing, session keys) |
Multi-Chain Support | Custom deployment per chain (high effort) | Native support for 10+ EVM chains (Ethereum, Polygon, Arbitrum, Base, etc.) |
Uptime & Reliability SLA | Your responsibility (potential downtime) | 99.9% uptime SLA with monitoring |
Total Cost of Ownership (Year 1) | $250K - $600K+ | Starts at $60K/year (Predictable OpEx) |
Team Focus | Diverts core team to infra management | Enables focus on core product features |

Frequently Asked Questions
Get clear answers on how our service works, its security, and how it integrates with your project.
Our service provides a managed, secure relay that sponsors gas fees for your users' transactions on EVM-compatible chains. You deposit funds into a smart contract you control. When a user submits a transaction, our off-chain service validates it against your custom rules (like whitelists or spending limits), signs a gas sponsorship approval, and submits it to the network. You retain full custody of the deposit funds at all times.
