Custom Logic & Features | Basic only | Fully customizable (staking, NFTs, subscriptions) |
Security & Audit Burden | You rely on their audit | We deliver audited, verifiable code |
Multi-Chain Support Flexibility | Their supported chains only | Any EVM chain you need |
Ongoing Maintenance Cost | Recurring platform fees | One-time build + optional SLA |
Data & Analytics Access | Limited dashboard | Full access to your data pipeline |
Total Cost of Ownership (Year 1) | $50K+ in fees | $80K-$150K one-time build |

Frequently Asked Questions
Get clear answers on timelines, security, and process for integrating blockchain payments into your platform.
A standard integration with a major wallet (e.g., MetaMask, WalletConnect) and 1-2 blockchains (like Ethereum, Polygon) typically takes 2-4 weeks from kickoff to production deployment. Complex requirements, such as multi-chain gas abstraction, fiat on-ramp aggregation, or custom token logic, can extend this to 6-8 weeks. We provide a detailed project plan with milestones after the initial scoping call.
