Frequently Asked Questions
Get clear answers on how we implement ERC-4337 and ERC-6900 to streamline your player onboarding.
A standard implementation, including a custom ERC-4337 Bundler, Paymaster, and Account Factory, takes 2-4 weeks from kickoff to mainnet deployment. Complex integrations with existing auth systems or multi-chain deployments may extend this to 6-8 weeks. We provide a detailed sprint plan during discovery.
