Case study
Aircraft deal platform
EthereumKYC/KYBe-signatureWebSocket3.5 years
The setting
Aircraft change hands through a long chain of verifications, documents, and payments — historically handled over email and courier. Our client set out to move the whole deal lifecycle online, for transactions where a single mistake is measured in millions.
What we built
- KYC/KYB verification for both private buyers and companies, integrated into onboarding rather than bolted on.
- Multi-party document signing — legally binding e-signatures orchestrated across buyer, seller, and intermediaries.
- Client-to-client transaction services carrying the deal through escrow-style stages.
- Tokenized deal lifecycle on Ethereum — each stage of the transaction anchored on-chain for auditability.
- Multi-channel notifications: WhatsApp, Telegram, push, and WebSocket updates keeping every party in sync.
Where it stands
We worked on the platform for 3.5 years — from architecture through production operation — covering backend, integrations, and the real-time layer as one accountable team.
