Startbahn
Fractional NFT ownership platform achieving 15 % gas savings and immutable Startrail provenance on Ethereum.
The Story
From Nov 2021–Oct 2022, I architected and deployed Startbahn's multi-access smart-contract suite atop Startrail, enabling galleries, artists and institutions to fractionally own and trade NFTs with on-chain provenance checks. The platform powered high-profile campaigns—ATAMI Art Grant scavenger hunts, Toyota Automobile Museum QR-to-NFT hunts, and WEC Fuji Metaverse fan rewards—while ensuring seamless IPFS metadata integration and audit-ready compliance.
The Problems We Tackled
Every great solution begins with understanding the core challenges that need to be addressed.
Challenge 1
Designing a tiered, multi-access smart-contract architecture for secure fractional governance
Challenge 2
Minimizing Ethereum gas costs under enterprise workloads without compromising security
Challenge 3
Seamlessly integrating on-chain provenance with off-chain IPFS metadata and third-party APIs
How We Solved It
Strategic approaches and innovative solutions that transformed challenges into opportunities.
Solution 1
Architected specialized Solidity contracts with gas-efficient execution paths and role-based access controls
Solution 2
Implemented end-to-end automated testing, formal security audits and continuous compliance checks
Solution 3
Built a flexible fractional-ownership engine with secure transfer, rebalance and on-chain provenance verification via Startrail API
The Outcome
Measurable impact and transformative results that exceeded expectations.
