Frequently Asked Questions
Get clear answers on our process, timeline, and security for integrating ERC-4337 smart accounts and paymasters.
A complete integration, from design to production, typically takes 3-6 weeks. This includes smart account deployment, paymaster setup, bundler configuration, and user onboarding flows. For a basic ERC-4337 wallet with a single paymaster, deployment can be as fast as 2 weeks. Complex multi-chain deployments with custom validation logic may extend to 8 weeks. We provide a detailed project plan within the first 3 days of engagement.
