overview
CORE SERVICES

Smart Contract Development

Secure, production-ready smart contracts built for scale and compliance.

We architect and deploy audited, gas-optimized smart contracts on EVM and Solana. Our code follows OpenZeppelin standards and includes formal verification for critical logic, ensuring your protocol's foundation is secure from day one.

  • Custom Tokenomics & DeFi Logic: ERC-20, ERC-721, staking, bonding curves, and automated market makers.
  • Security-First Development: Multi-sig deployment, upgradeable proxy patterns, and comprehensive unit/integration testing.
  • End-to-End Delivery: From technical specification to mainnet deployment and monitoring—we handle the entire lifecycle.

Reduce your time-to-market from months to weeks with our battle-tested development framework and 99.9% uptime deployment guarantee.

Business Outcomes of a Decentralized Mobile Backend

Migrating from a centralized mobile backend to a decentralized architecture delivers measurable improvements in cost, performance, and user trust. Here’s what our clients achieve.

01

Radical Cost Reduction

Eliminate ongoing cloud hosting, database, and middleware licensing fees. With decentralized storage and serverless compute, you pay only for the transactions your users make, reducing backend operational costs by up to 70%.

Unbreakable Uptime & Resilience

Decouple from single points of failure. Leverage globally distributed networks like IPFS and Arweave for storage and decentralized oracles for data feeds, achieving 99.9%+ availability without managing server clusters.

Enhanced User Trust & Data Sovereignty

Users own their data via non-custodial wallets and encrypted storage. This transparent, user-centric model builds unparalleled trust and reduces liability from data breaches, a key differentiator for FinTech apps.

Our Phased Migration Methodology

We execute your mobile app's transition from legacy to decentralized infrastructure with zero downtime. Our proven, step-by-step approach ensures data integrity, user retention, and continuous operation throughout the migration lifecycle.

01

Phase 1: Discovery & Architecture

We conduct a comprehensive audit of your existing mobile stack, mapping APIs, data models, and user flows. Our team designs a hybrid architecture blueprint, identifying which components to decentralize first (e.g., user authentication, payment rails, data storage) for maximum impact with minimal disruption.

Phase 2: Hybrid Integration Layer

We build and deploy a secure, scalable middleware layer that bridges your legacy mobile backend with new Web3 services (wallets, smart contracts, oracles). This allows for gradual feature migration, enabling users to interact with both systems seamlessly during the transition.

Phase 3: Incremental Feature Migration

We migrate high-value features one module at a time—starting with non-critical paths like loyalty points (ERC-20) or NFT avatars (ERC-721). Each migrated module undergoes rigorous testing in staging, with canary releases to a subset of your production user base to validate performance and security.

Phase 4: Full Decentralization & Decommission

Once all core functionalities are live on the decentralized stack, we execute the final cutover. We ensure all user data is ported, legacy systems are securely decommissioned, and the new mobile app operates entirely on its optimized Web3 infrastructure, with comprehensive monitoring in place.
