Challenge

Move value across different blockchain environments without introducing a trusted bridge operator.

02

Responsibility

Protocol and full-stack development in a four-person hackathon team.

03

Solution

Combined Aleo private-by-default primitives with Solidity contracts, an atomic-swap flow, and a React interface.

04

Outcome

Won four ETHBarcelona prize tracks totaling more than $12,000, alongside 403 community votes and a $1,537 quadratic-voting match.

Engineering decisionsD-01
01

Atomic settlement

The exchange flow was designed around atomic swaps so either both sides settle or neither side does.

02

Privacy-aware liquidity

Aleo and zero-knowledge primitives were used to explore private cross-chain exchange and liquidity provision.

03

Hackathon scope discipline

The team prioritized a verifiable protocol path and working demonstration within the event time limit.
