- Hybrid data strategy (On-chain hashes, Off-chain docs)
Challenges & Solutions
Trustless Equity Issuance
To prevent founders from arbitrarily printing shares, I implemented a "Hub and Spoke" factory pattern. The central Funding Contract deploys the Equity Token and assigns itself as the Admin, ensuring shares are only minted programmatically when investments are verified.
Preventing "Rug Pulls"
Designed a strict Finite State Machine (FSM) where funds are held in escrow. Capital is released to the startup only when specific milestones move from "AwaitingValidation" to "Successful" via cryptographic proof, protecting investor funds.
Programmatic Infrastructure
Abstracted the complexity of blockchain for non-technical founders. The `create_project` function utilizes `deployer.deploy_v2` to automatically spawn regulated digital equity infrastructure (SEP-41 tokens) without the user writing a single line of code.
My Role
Lead Protocol Architect responsible for the Rust smart contract implementation, Soroban integration, and the design of the core FSM security logic.

Results
Successfully architected a "protocol for conditional capital formation" that bridges the gap between Venture Capital compliance and DeFi composability, turning equity from a paper promise into a trustless, programmable primitive.
