Frequently Asked Questions
Get clear answers about our custom Substrate pallet development service, from timelines and pricing to security and ongoing support.
A standard private transaction queue pallet with core features (private mempool, ordering logic, basic access control) typically takes 2-4 weeks from kickoff to testnet deployment. Complex integrations (e.g., custom ZK proofs, multi-chain relayers, advanced governance) can extend this to 6-8 weeks. We provide a detailed project plan with milestones after the initial technical scoping call.
