Frequently Asked Questions
Get clear answers on timelines, security, and process for implementing custom streaming wallets.
A standard ERC-4337-compliant streaming wallet with core features (batch transactions, session keys, gas sponsorship) typically deploys in 2-4 weeks. Complex implementations with custom logic, multi-chain support, or advanced recovery mechanisms can take 6-8 weeks. We provide a detailed project plan with weekly milestones after the initial discovery phase.
