Frequently Asked Questions
Get clear answers on timelines, security, costs, and technical specifics for building cross-chain identity bridges for DePIN projects.
A standard, production-ready DePIN identity bridge with core features (e.g., tokenized identity attestation, multi-chain verification) takes 4-6 weeks from kickoff to mainnet deployment. Complex integrations (e.g., custom consensus for identity states, support for 5+ chains) can extend to 8-10 weeks. We follow a phased delivery model with weekly sprints and milestone reviews.
