Below is Clutch Protocol, my side project, and where the Rust on this profile comes from.
An open-source, decentralized ride-sharing network I designed and built from scratch — the whole ride lifecycle (request → offer → accept → pay → cancel) settles as first-class transactions on a custom non-EVM blockchain written in Rust. Grew out of my master's thesis.
