Hi, I'm Utkarsh aka Zyaxxy a full-stack blockchain developer building at the intersection of Web3, distributed systems, and full-stack development, with a curiosity for security. I'm a Turbin3 graduate and a Tata HackQuest Season 10 CTF finalist.
I'm currently building Kite, an investing platform on Solana, and exploring projects in DeFi, on-chain protocols, and AI. I enjoy turning complex ideas into useful, intuitive experiences.
SOLANA / FANTASY SPORTS
A decentralized trading and fantasy sports protocol that brings athlete token markets, lineup drafting, and live contest settlement onto Solana.
Full-stack & smart contract engineering
A market built from explicit instructions.
An Anchor marketplace for Metaplex Core assets, with token-denominated listings, SOL offers, treasury fees, and buyer reward minting.
The marketplace exposes a documented instruction surface for listing, buying, offering, and cancelling. Its README describes the expected accounts, PDA seeds, validation rules, and settlement flow for client integrations.
A listing holds a Core asset under program authority and specifies its payment mint. Buyers can pay with SPL tokens or lock lamports in an offer vault for a seller to accept.
Settlement splits the maker payment and marketplace fee, transfers the asset through a Core CPI, and mints buyer rewards. Cancellation and administrative withdrawals enforce the relevant account authority.
