Cross-Chain Mobile Identity Wallet Development

We build secure mobile wallets that manage a single, portable identity and verifiable credentials across EVM, Cosmos, and Polkadot ecosystems using IBC and CCIP.

overview
FULL-STACK IMPLEMENTATION

Custom Blockchain Development

End-to-end blockchain solutions from protocol design to mainnet deployment.

We architect and build production-grade blockchain systems tailored to your specific business logic. Our full-cycle development delivers a complete, audited, and deployable product, not just code.

From initial concept to a live network, we manage the entire lifecycle with a focus on security, scalability, and long-term maintainability.

  • Core Protocol & Smart Contract Development: Custom Solidity, Rust (Solana), or Move (Aptos/Sui) contracts with formal verification patterns.
  • Node Infrastructure & Consensus: Private EVM-compatible chains, Substrate-based parachains, or Cosmos SDK app-chains.
  • Full-Stack dApp Integration: Front-end (React/Next.js), back-end indexers (The Graph), and secure wallet connectivity.
  • Deployment & DevOps: Automated CI/CD pipelines, mainnet launch coordination, and 24/7 monitoring with defined SLAs.

TRANSPARENT & PREDICTABLE

Our Development & Delivery Process

A structured, milestone-driven approach that de-risks development, ensures alignment, and delivers a secure, production-ready mobile identity wallet on time and on budget.

01

Discovery & Architecture Design

We conduct a deep technical workshop to define your cross-chain strategy, user flows, and key integrations. You receive a detailed technical specification and architecture diagram for sign-off, ensuring zero surprises later.

Frequently Asked Questions

Get clear answers on development timelines, security, and support for your cross-chain identity wallet project.

From initial specification to App Store/Play Store deployment, a minimum viable product (MVP) takes 6-8 weeks. This includes core features like multi-chain key management, a basic UI, and integration with 2-3 target blockchains (e.g., Ethereum, Polygon, Solana). Full-featured production wallets with advanced identity features (SSI, verifiable credentials) typically require 12-16 weeks.
