A selection of recent entries and experiments.

Live on Base Sepolia (testnet): agent NFT stack combining ERC-8004 on-chain identity + reputation with x402 (USDC) micropayments to paywall agent HTTP endpoints, plus an Express API for metadata/images and a React + Vite frontend agent gallery.

Research-grade modular stablecoin protocol focused on gas efficiency and safety guardrails: validated oracle with fallback, collateral accounting, direct + Dutch auction liquidation, arbitrage/repeg coordination, and a timelock for sensitive actions (local-only, no mainnet required).

A branded storefront on the AgenC agent-marketplace protocol for hiring AI agents on Solana mainnet, with on-chain escrow where every settlement is an atomic 4-way split backed by a verifiable receipt.

Solana SPL staking dApp built with Anchor + React: stake tokens, accrue rewards, and claim later via PDA-managed config/vaults and program-owned reward mint authority.

ERC-4337 smart account dApp on Sepolia that emits messages as events (no storage), indexed via The Graph for pagination. Includes AA flows with EntryPoint v0.7, optional paymaster sponsorship, and a React frontend.

Solana multi-send dApp that batches SOL transfers using v0 versioned transactions and Address Lookup Tables (ALT), handling large recipient lists with chunked ALT extension, robust validation, fee estimation fallback, and optional ALT close to reclaim rent.

A live leaderboard that ranks AgenC marketplace agents purely from Solana on-chain data, read through the official AgenC SDK with zero REST dependencies, featuring telemetry, a 30-day network pulse, and transparent re-rankable scoring.

An interactive N-body gravity sandbox in the browser where orbits emerge from a single rule and total energy never drifts, built on a symplectic integrator with an optional Barnes-Hut approximation and a Web Worker physics core.

A browser-based Darwinian artificial-life simulation where digital organisms hunt, breed, and die through emergent behavior with no fitness function, featuring bit-for-bit deterministic replay and off-main-thread rendering.

A browser platformer where real incompressible fluid dynamics are the physics engine: a glowing liquid character crosses 100 levels driven by a dual CPU and GPU simulation, WebGL2 rendering, and procedural Web Audio.

A cinematic, terminal-only simulated web OS built with Next.js: a stateful shell with a persistent filesystem, multi-host SSH, a process table, and a mission and CTF system, styled like a compromised Linux host.

CryptoLens is a Web3 dashboard to explore tokens, manage favorites, and view charts with secure Google + wallet auth (SIWE + fallback signing), Supabase RLS, and a Redis-backed price cache.

HashNotes is a minimalist notes dApp built with Next.js App Router that pins short notes to IPFS via Pinata, returning shareable CIDs and gateway links with validation, rate limits, and CSP hardening.

Rate-limited ERC-20 faucet on Sepolia with a React + Vite frontend (RainbowKit/wagmi) and a Hardhat 3 backend (Ignition). Includes cooldowns, per-address limits, daily caps, and real-time UI updates via Transfer event watching.

Solidity + frontend dApp where each new message must start with the last message’s keyword, and the next keyword is derived from the last word, with validation, pagination, search, custom errors, and reentrancy protection on Sepolia.

Dynamic ERC-721 on Sepolia where tokenURI returns a base64 JSON + on-chain SVG whose color shifts with time. Includes Hardhat/Ignition deployment, unit tests, and a polished React minting/gallery frontend.

Modern multi-chain dApp to send ETH/tokens with custom gas controls, live balances, and transaction history (filter/search/CSV export), built with wagmi + RainbowKit + Alchemy.

Advanced honeypot platform (Flask + React) that simulates vulnerable services to attract attackers and logs threats in real time with classification, rate limiting, Redis-backed telemetry, optional AbuseIPDB enrichment, and Telegram alerts.

Telegram bot that delivers rare words on /word with no-repeat cycling, user stats, and robust modular Node.js architecture with structured logging and validation.

Production-ready React + TypeScript + Vite template with strict typing, lint/format gates, Vitest + RTL coverage, Playwright E2E, Conventional Commits, and automated CI + GitHub Pages deploy.

Console-based Python wallet manager built fully offline during a power outage, using pandas + CSV to manage balances, compute stats, and apply simple/compound interest.

AI-powered startup name generator using Gemma (google/gemma-3-270m-it) with a Gradio UI and built-in domain availability checks across multiple TLDs.

Fun Web3 dApp that generates a personalized daily horoscope from your Ethereum address, including zodiac traits, rarity, advice, challenges, and shareable exports.

React + Solidity dApp to deposit and withdraw ETH on Sepolia with MetaMask integration, contract/wallet balance views, address lookup, and a ReentrancyGuard-protected smart contract.
