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 βeligibility driftβ: 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-Tokenβs 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) β€ 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’π 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
Smart Contract Raffle
Provably fair blockchain lottery system
Utilizes Chainlink VRF for verifiable randomness and Chainlink Automation for seamless execution, built with cross-chain deployment capability.
- β’Chainlink VRF for verifiable randomness
- β’Automated execution via Chainlink Keepers
- β’Cross-chain deployment with mock testing
- β’Gas-optimized raffle mechanics

Swarm Escrow
Jul 2026AI Agent Escrow on BOT Chain β where agents align on every deliverable.
Won #3 β BOT Chain Builder Challenge #1A 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’β οΈ No third-party security audit was performed before mainnet deployment (disclosed in the writeup)
Smart Road Damage Detection System
March 2026Aixpo Β· College Hackathon Β· with Lokesh Kumar Singh
Won #1AI-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
Wallet Spy
Jan 2026Solana Privacy Hack Β· Solo entry
A privacy-focused wallet surveillance tool built on Solana.
- β’Privacy-focused wallet analysis on Solana
- β’Real-time wallet activity monitoring
- β’Solo hackathon project
