About Utkarsh Jaiswal

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.

DeXI

A new field of play.

A decentralized trading and fantasy sports protocol that brings athlete token markets, lineup drafting, and live contest settlement onto Solana.

FIG. 001 / DEXIA new field of play.

Overview.

DeXI connects the decisions of fantasy sports with the mechanics of an on-chain market. Players can trade athlete tokens, draft contest lineups, and participate in a protocol where entry validation and settlement are handled by smart contracts.

A market around the match.

Automated market-making and liquidity pools support athlete token trading. On-chain contest logic enforces lineup constraints, validates entries, and manages automated settlement.

From the fixture to the chain.

An oracle telemetry pipeline consumes live fixture events through TxLINE SSE streams and computes fantasy scores. USDC escrow settlement follows a 90/10 distribution, while an automated keeper uses V0 versioned transactions to submit lineup entries atomically.
