TRANSPARENT & PREDICTABLE
Our Development & Integration Process
A structured, four-phase methodology designed for technical founders to achieve rapid, secure, and scalable mobile wallet deployment. We provide clear deliverables and timelines at every step.
01
Phase 1: Discovery & Architecture
We conduct a technical deep-dive to define your wallet's core architecture, token standards (ERC-20, ERC-721, SPL), and key integrations (DeFi protocols, NFT marketplaces). Deliverables include a detailed technical spec and project roadmap.

Frequently Asked Questions
Get clear answers on our process, timelines, and technical approach for building secure, scalable mobile wallet applications.
We deliver a production-ready MVP in 6-10 weeks, depending on feature complexity. A basic wallet with multi-chain support (EVM + 1 non-EVM) and core features (send/receive, token management) typically takes 6-8 weeks. Advanced features like DeFi integrations, NFT galleries, or custom transaction builders extend the timeline. We provide a detailed sprint-by-sprint breakdown during the discovery phase.
