A PROVEN FRAMEWORK
Our Development & Integration Process
We deliver secure, production-ready account abstraction wallet bridges through a structured, transparent process designed for rapid deployment and long-term reliability.
01
Architecture & Smart Contract Design
We architect your system using ERC-4337 standards, designing gas-efficient Smart Accounts, Paymasters, and Bundlers. Our contracts are built with OpenZeppelin libraries and include multi-signature recovery and session key management from day one.

Frequently Asked Questions
Get clear answers on our process, timeline, and technical approach for building secure, scalable mobile wallet bridges.
From kickoff to mainnet deployment, a standard Account Abstraction (ERC-4337) mobile wallet bridge takes 4-8 weeks. This includes smart contract development, bundler/paymaster integration, mobile SDK implementation, security audit, and testing. Complex multi-chain deployments or custom gas sponsorship models may extend the timeline, which we scope and agree upon before project start.
