PROVEN METHODOLOGY
Our Development & Integration Process
A structured, four-phase approach to deliver secure, scalable, and production-ready autonomous device wallets. We focus on rapid iteration and measurable outcomes, ensuring your project moves from concept to live deployment efficiently.
01
Architecture & Smart Contract Design
We design the core smart account system using ERC-4337 and ERC-6900 standards. This includes defining modular account logic, bundler/paymaster strategies, and gas optimization patterns for predictable device operation costs.

Frequently Asked Questions
Common questions from CTOs and technical founders about implementing autonomous device wallets with ERC-4337.
A production-ready MVP typically deploys in 3-5 weeks. This includes smart account factory setup, custom paymaster integration, bundler configuration, and device SDK implementation. Complex multi-chain deployments or custom signature schemes may extend to 8-10 weeks. We provide a detailed sprint plan during the initial technical discovery phase.
