AeroChain is building a decentralized protocol and infrastructure suite that enables aircraft manufacturers (OEM), airlines, and MROs to track the full lifecycle of aircraft parts using blockchain technology.
With this Stellar Build submission, we will:
Finalize and deploy Soroban smart contracts for parts traceability: Each aircraft part will be registered on-chain with a unique identifier. Ownership, certification status, usage metrics, and transfer events will be immutably recorded.
✅ Stellar Use: Uses Soroban to anchor verifiable part metadata and status updates on-chain.
🎯 Impact: Brings transparency, combats counterfeit parts, and simplifies audits.
Develop a REST API to simplify interactions with the Soroban smart contracts: AeroChain will expose an API layer for third-party integration. OEMs, MROs, Operators (Airlines) can push events like inspections, installations, and certifications without directly managing smart contracts.
✅ Stellar Use: The API wraps Stellar’s transaction logic, enabling role-specific operations via Soroban contracts.
🎯 Impact: Lowers the barrier to adoption by integrating with existing ERP and maintenance tools.
Launch a reference app (AeroChain App) tailored to MROs: This front-end application will allow MROs to register parts, update their status, and view certified histories. Additional dashboards for OEMs and regulators will follow.
✅ Stellar Use: Reads contract state via Horizon/Soroban RPC and pushes certified updates to Soroban.
🎯 Impact: Enables rapid onboarding and provides an off-the-shelf solution for early adopters.
Offer a developer SDK (Rust + Typescript): The SDK abstracts away the complexity of the Soroban environment and exposes typed helpers to build on-chain workflows faster.
✅ Stellar Use: Wraps Soroban logic with tested client libraries.
🎯 Impact: Facilitates third-party integrations and encourages an ecosystem of complementary apps.
