Asset Passport

Working in an accounting firm, this is an idea that I felt very attached to. Asset Passport is a comprehensive fixed asset accounting app that brings blockchain transparency to traditional business asset management. Built specifically for SMBs, contractors, and asset-heavy operators, it creates tamper-evident, verifiable records of real-world assets from acquisition through disposal. This is built as a direct competitor to applications like Xero and QuickBooks, which SMBs use today and spend up to $1000 in subscription fees yearly. We built the app with the goal of helping SMBs prove auditability of their fixed assets through verifiable transaction records on the blockchain that they can easily share with insurers, buyers, auditors, etc.

The platform abstracts away all blockchain complexity - users simply log in with email or connect wallets to access professional depreciation tracking, lifecycle management, and compliance reporting. Each asset gets a permanent, shareable verification URL for auditors, buyers, or partners.

Key features include automated straight-line depreciation calculations, timeline simulation for demos, bulk CSV asset imports, public verification pages, and seamless integration with existing accounting workflows. The solution targets the gap between traditional asset tracking spreadsheets and the need for verifiable, portable proof of asset existence and history.

Perfect for equipment financing, insurance claims, compliance audits, and asset transfers - providing Web3 benefits without requiring crypto knowledge.

This project is built on the Flow EVM blockchain, which we’re using as the core infrastructure for smart contract deployment. The choice of Flow gives us scalability and cost efficiency for recording and verifying asset data on-chain. For wallet authentication, we’re using Dynamic Labs SDK, which supports both embedded wallets for users who prefer simple email logins and native wallet connections for those already using crypto wallets. That way, the system can meet users where they are, without creating friction around key management or onboarding.

On the frontend, we’ve built a React 18 application using functional components and hooks to create a clean, SaaS-like dashboard experience. Under the hood, the architecture is supported by multiple specialized smart contracts. The AssetRegistry contract establishes canonical asset identities, the LifecycleEvents contract manages append-only timeline updates that track changes to assets over time, and the DepreciationAnchors contract stores accounting parameters in a verifiable way so that financial reporting can’t be tampered with.

Supporting documents — such as receipts, photos, or certificates — are stored in Walrus decentralized storage, with only the content hashes written to the blockchain for verification. To make the data usable in a dashboard context, The Graph indexes all blockchain events so queries and analytics can be returned quickly without sacrificing transparency. On top of that, ENS integration is included to provide human-readable asset identifiers, making the user experience more intuitive.

The authentication flow follows a Flow-first design but remains Ethereum-compatible, which allows embedded wallet users to have genuine blockchain addresses and interact with smart contracts without needing to understand crypto. This is important because it shows how Web3 infrastructure can deliver real business value while still looking and feeling like the kind of software people are already comfortable with.

For the hackathon demo, we’ve emphasized the timeline simulation feature that lets judges and users fast-forward or rewind through the lifecycle of an asset, instantly seeing changes in status, depreciation, and overall value. The build has been optimized for rapid deployment but still follows production-ready architectural patterns so that it can scale and extend beyond the demo environment.

Overall, this project highlights a mix of practical business value and technical innovation while showcasing integrations with sponsor technologies like Flow, Dynamic, Walrus, ENS, and The Graph. The intent is to deliver something that is not only hackathon-ready but also credible as a real-world Web3 application.
