Frequently Asked Questions
Get clear answers on our process, security, and timelines for implementing ERC-4337 wallet infrastructure.
A standard ERC-4337 smart account deployment with core features (social login, gas sponsorship, batched transactions) takes 2-4 weeks from kickoff to mainnet launch. Complex integrations with custom paymasters or multi-chain bundlers may extend to 6-8 weeks. We provide a detailed project plan within the first 3 days of engagement.
