Technical FAQs for DePIN Founders & CTOs
Common technical questions from founders evaluating payment sub-wallet infrastructure for their DePIN networks.
A standard deployment for a DePIN payment sub-wallet system takes 2-4 weeks from kickoff to mainnet launch. This includes smart contract development, integration with your existing device firmware/backend, and a full security audit. Complex multi-chain deployments or custom reward distribution logic can extend this to 6-8 weeks. We provide a detailed project plan with weekly milestones.
