PROVEN METHODOLOGY
Our Development & Integration Process
A structured, four-phase approach to deliver secure, production-ready wallet interoperability. We focus on rapid deployment, rigorous security, and seamless integration into your existing stack.
01
Discovery & Architecture
We conduct a technical deep-dive to define your cross-chain requirements. Deliverables include a detailed architecture diagram, protocol selection (e.g., Axelar, Wormhole, LayerZero), and a phased implementation roadmap.
Client Value: Eliminates scope creep and aligns technical strategy with business goals from day one.

Frequently Asked Questions
Get clear answers on how we build secure, seamless wallet experiences that work across any blockchain.
A production-ready MVP with core interoperability features (e.g., multi-chain account abstraction, token bridging UI) typically deploys in 4-6 weeks. Complex deployments with custom smart accounts, advanced MPC setups, or support for 10+ chains can take 8-12 weeks. We provide a detailed sprint-by-sprint roadmap during discovery.
