Frequently Asked Questions
Get clear answers on timelines, security, and process for integrating secure wallet connectivity into your DeFi application.
Standard integrations for a single wallet provider (e.g., MetaMask, WalletConnect) take 2-3 weeks from kickoff to production deployment. Multi-wallet support (3-5 providers) or complex DeFi-specific features like transaction simulation and gas sponsorship typically extend the timeline to 4-6 weeks. We provide a detailed project plan in the first week.
