The
Challenge
Ecosystem hackathons and developer bounty programs frequently suffer from administrative delays, manual payout handling, opaque judging systems, and international wire transfer friction. Organizers need a transparent, smart-contract-enforced platform to lock bounty funds and disburse prizes automatically upon submission approval.
The
Strategy
I engineered Stallion on the Soroban smart contract framework for the Stellar ecosystem:
1. Soroban WASM Escrow Smart Contracts in Rust
Wrote Soroban smart contracts in Rust that lock sponsor bounty funds in on-chain escrow pools. Contracts enforce multi-signature judge authorizations before releasing prize payouts directly to winning developer wallet addresses.
2. Next.js 16 Developer & Organizer Portal
Built an operational web application using Next.js 16 and Stellar SDK (Freighter / Albedo wallet integration), allowing developers to browse active bounties, submit pull requests, track leaderboards, and claim prize rewards instantly.
