Challenge
Move value across different blockchain environments without introducing a trusted bridge operator.
Responsibility
Protocol and full-stack development in a four-person hackathon team.
Solution
Combined Aleo private-by-default primitives with Solidity contracts, an atomic-swap flow, and a React interface.
Outcome
Won four ETHBarcelona prize tracks totaling more than $12,000, alongside 403 community votes and a $1,537 quadratic-voting match.
Atomic settlement
The exchange flow was designed around atomic swaps so either both sides settle or neither side does.
Privacy-aware liquidity
Aleo and zero-knowledge primitives were used to explore private cross-chain exchange and liquidity provision.
Hackathon scope discipline
The team prioritized a verifiable protocol path and working demonstration within the event time limit.
