PROVEN METHODOLOGY
Our Development & Delivery Process
We deliver production-ready, interoperable metaverse applications through a structured, transparent process designed for technical founders. Each phase includes clear deliverables, security checkpoints, and direct collaboration with your team.
01
Architecture & Protocol Design
We architect your app's core interoperability layer, selecting and integrating protocols like ERC-6551 for token-bound accounts and LayerZero for cross-chain communication. This phase defines the technical blueprint for seamless asset and identity portability.

Smart Contract Development & Audit
Our engineers write gas-optimized Solidity/Vyper contracts for core logic (wallets, bridges, marketplaces). All code follows OpenZeppelin standards and undergoes internal review before a mandatory third-party audit from firms like Spearbit or CertiK.

Frequently Asked Questions
Get clear answers on our development process, timelines, and technical approach for building cross-platform mobile metaverse applications.
A core MVP with wallet integration, basic asset interoperability, and one metaverse connection typically takes 8-12 weeks. Full-featured platforms with multiple world integrations, advanced social features, and a custom marketplace can take 4-6 months. We provide a detailed sprint-by-sprint roadmap after the initial discovery phase.
