DePIN Account Abstraction: Key Questions
Answers to the most common questions from CTOs and founders evaluating our DePIN Account Abstraction Toolkit.
For a standard DePIN project, we deliver a production-ready, audited Account Abstraction (AA) stack in 3-5 weeks. This includes a 1-week discovery & design phase, 2-3 weeks of core development and integration, and a final week for security review and deployment. Complex integrations (e.g., custom paymasters, multi-chain deployments) may extend this by 1-2 weeks. We provide a detailed sprint plan on day one.
