Offshore Development Center for Blockchain-Based Smart Contract Platform
InApps built a dedicated offshore engineering team for Vleppo to launch a blockchain-native platform where legal documents are created, validated, and executed as smart contracts, from architecture through a funded Phase 1 and into Phase 2.
Trusted by engineering teams across 15+ countries
From startups to Fortune 500 companies
PROJECT OVERVIEW
Turning Legal Documentation Into a Blockchain-Verified Product
B2B PlatformVleppo set out to modernize how legal agreements get created and executed, combining lawyer-drafted templates with blockchain-based validation, so documents like shareholder agreements or loan contracts could be issued, copied, and verified without the usual paperwork friction. As an EU-based company building a technically complex product spanning smart contracts, digital asset management, and a multi-platform desktop app, Vleppo needed an engineering partner who could move fast without sacrificing the precision blockchain development demands.
InApps embedded a dedicated ODC team directly into Vleppo's roadmap, covering architecture, blockchain engineering, and cross-platform delivery, carrying the product from a credible Phase 1 launch into ongoing Phase 2 development.
Build a multi-service blockchain platform: digital asset validation, exchange, and management
Implement smart contract logic for binding digital agreements
Ship a single desktop application compatible across macOS, Windows, and Linux
Integrate CRM functionality to manage client and document relationships
Support a growing catalog of legal document templates (property, shareholder, loan, asset sale, licensing)
WHAT THEY NEEDED
Client Requirements
Across each key area, these requirements shaped every architectural and product decision we made.
Blockchain & Smart Contract Expertise
Vleppo needed engineers fluent in blockchain protocols and Solidity to power digital asset validation and contract execution, not generalist web developers.
Cross-Platform Desktop Application
A single codebase needed to run natively across three operating systems without fragmenting development effort.
Legal Document Infrastructure
The platform needed to support an expanding library of lawyer-drafted templates, each blockchain-enabled for verification.
Investor-Ready Technical Delivery
Phase 1 needed to be stable and demonstrable enough to support an active fundraising conversation.

HOW WE SOLVED IT
Our Solutions
Each solution addresses a specific pain point while contributing to a unified, future-proof platform, from infrastructure to mobile to AI, every layer rebuilt with scale, security, and speed in mind.
Dedicated Blockchain Engineering Team
A focused ODC team with Solidity and Ethereum experience built the digital asset validation, exchange, and smart contract layers from the ground up.
Native Multi-OS Application Build
Engineered a single application architecture deployable across macOS, Windows, and Linux without splitting the codebase into platform-specific forks.
Milestone-Driven Delivery Model
Structured Phase 1 around clear, demonstrable milestones, giving Vleppo's leadership concrete technical proof points to bring into investor conversations.
Direct Engineering Communication
Vleppo's team worked directly with InApps engineers, no PM layer in between, keeping blockchain-specific technical decisions fast and accurate across timezones.
