DePIN Cross-Chain Messaging: Key Questions
Answers to the most common technical and commercial questions about deploying our DePIN cross-chain messaging library.
Standard integration of our DePIN cross-chain messaging library takes 2-4 weeks from kickoff to production readiness. This includes initial setup, smart contract adaptation, testing on testnets, and final deployment. Complex multi-chain architectures or custom protocol integrations may extend this to 6-8 weeks. We provide a detailed project plan during the initial technical scoping call.
