Talon

On-chain transfer agent for Cleanverse-verified real-world assets β€” Cleanverse Build Hackathon (RWA track), solo build

Every RWA project stops at issuance; Talon runs everything that happens after β€” coupons, dividends, redemptions β€” and solves β€œeligibility drift”: when a verified holder's identity lapses between the record date and the pay date. It pays every holder still compliant, escrows the rest per-beneficiary (never forfeited), and releases the moment they re-verify.

  • β€’Never re-implements compliance: the Cleanverse A-Token’s own on-chain revert is the eligibility check, and escrow release is a retry of that same real transfer
  • β€’Deployed and frozen on Monad testnet β€” EscrowVault + CorporateActionManager, with resumable batched payouts and a chained-hash commitment against replay
  • β€’Frozen, expired, and no-pass are kept as distinct on-chain reasons β€” lapsed β‰  sanctioned β€” never conflated, all the way down to the audit trail
  • β€’90 contract tests green (unit, fuzz, cross-contract invariants) proving sum(ledger) ≀ vault balance; a live smoke test moves real aUSDC end to end
  • β€’All six Cleanverse integrations live, none mocked; a TypeScript backend indexes the chain into a Supabase read-mirror, polls A-Pass state, and builds a verifiable audit pack

Prompt Arena

Full-stack, real-time AI writing competition platform

Hosted a live event with 50+ student participants, handling concurrent team registrations, real-time test entries, and automated evaluation under production load.

  • β€’Complete competition lifecycle engine (draft β†’ scheduled β†’ live β†’ ended β†’ evaluating β†’ completed) with server-side state reconciliation
  • β€’Role-based access control for admins and students with a lobby-based dashboard and real-time countdown
  • β€’Uniquely assigned questions per team per section, with auto-finalization of unsubmitted answers on timeout
  • β€’AI-powered evaluation using Google Gemini and Anthropic Claude APIs with a per-competition provider selector
  • β€’πŸ† Automatic leaderboard generation after scoring; hosted 50+ concurrent participants in production

Decentralized Stablecoin

Algorithmic, over-collateralized stablecoin protocol

Users deposit WETH and WBTC as collateral to mint USD-pegged tokens, with over-collateralization, liquidation mechanisms, and comprehensive security measures.

  • β€’Deposit WETH/WBTC for USD-pegged token minting
  • β€’Liquidation system with incentive bonuses
  • β€’ReentrancyGuard and custom security modifiers
  • β€’30+ comprehensive unit tests

Swarm Escrow

Jul 2026

AI Agent Escrow on BOT Chain β€” where agents align on every deliverable.

Won #3 β€” BOT Chain Builder Challenge #1

A freelance/marketplace escrow contract where three independent AI agents vote 2-of-3 on whether a submitted deliverable meets its spec, before funds are released or refunded β€” every verdict hashed on-chain for a tamper-evident, portable proof of work. Solo build.

  • β€’Multi-agent 2-of-3 quorum (Reviewer, FraudSanity, Arbiter) reviews each deliverable β€” no single AI verdict can move funds
  • β€’Disputed cases escalate to a 4th, human-configurable Senior Arbiter with a fixed challenge window
  • β€’83/83 Foundry tests passing (72 unit, 9 fuzz, 2 invariant), Slither clean
  • β€’Deployed live on both BOT Chain testnet and mainnet, with a fully wired frontend β€” no mock data
  • β€’βš οΈ No third-party security audit was performed before mainnet deployment (disclosed in the writeup)

Smart Road Damage Detection System

March 2026

Aixpo Β· College Hackathon Β· with Lokesh Kumar Singh

Won #1

AI-powered road damage detection and repair-priority planning using YOLOv8, built to help municipalities triage India's 6.3M km road network instead of relying on slow, manual inspection.

  • β€’YOLOv8 model fine-tuned on 47,000+ real road images (RDD2022 dataset) detects potholes, cracks, and surface damage from a single uploaded photo
  • β€’Computes severity, repair priority, and estimated repair cost per detection, with an interactive Folium map and downloadable CSV report
  • β€’Weighted priority score (60% severity, 25% traffic impact, 15% simulated safety risk) sorts repairs by urgency
  • β€’3-tier model fallback strategy (fine-tuned model β†’ generic YOLOv8n β†’ OpenCV mock detection) so the app degrades gracefully instead of failing
