## Projects

### Khaata

The modern khaata for the stablecoin economy — a non-custodial USDC point of sale and merchant ledger on Solana. Payments settle straight to the merchant's own wallet in a single transaction with a cashier attestation, every receipt is a verifiable Solana signature, and the cashier POS, hosted checkout, dashboard, and onboarding all run against real on-chain + Postgres infrastructure. An Anchor program is the source of truth for money: atomic pay_invoice with treasury fee-split plus sequence-guarded refunds.

### sous

Your sous-chef for Cookie Chain — quotes, swaps, staking, limit orders, and bridging behind a paper-ticket review step. Every money move prints an estimate with guaranteed floor, venue, and both fees before the wallet ever opens, then signs in Nightly with a Cookiescan receipt. Browsing is free and read-only; only firing needs a wallet, and the app never holds keys — signing stays in an external MCP sidecar.

### Praxis

A conversational Solana agent: you type intent in plain language — 'send 0.5 SOL to maya' — and it becomes a typed, simulated on-chain action. The safety thesis is one sentence: the agent may interpret intent, but the program enforces the envelope. Aegis, an Anchor program, validates every transfer on-chain against an owner-defined policy — signer, pause, expiry, per-transaction cap, rolling daily cap, recipient allow-list, and SPL mint/token limits — before any value leaves the vault, so a jailbroken LLM or compromised backend stays bounded by the policy, not by prompt quality. Intent is parsed (Google Gemini, or a local deterministic parser for $0 demos), recipients resolve through an off-chain address book, and each action is simulated into a proposal card showing the fee, simulation result, and Aegis verdict before you confirm. Owner actions stay wallet-signed and the backend never holds the owner key. Ships with @usepraxis/sdk, a typed Node client, and a LiteSVM enforcement test gate.

### Get Toasted

Production SaaS that scans any Solana wallet for sandwich attacks and quantifies the USD lost to MEV. A typed detection pipeline in @get-toasted/core classifies front-run, victim, and back-run sets per slot with confidence scoring, priced via Jupiter Lite quotes. Real-time detection runs through HMAC-verified Helius webhooks; historical scans are paginated through BullMQ workers. Validated against Jito bundle ground truth with a 30/30 match rate. Turborepo monorepo: Next.js 16 dashboard, Hono API, and four dedicated workers (scanner, detector, risk-analyzer, validator-refresh) backed by Neon Postgres and Upstash Redis. Auth is Sign In With Solana, ed25519 verified, JWT issued.

### GhostTip

Privacy-first social tipping on Solana — tip anyone by X handle. Claims are gated by X OAuth, settlement runs through a private rail, and unclaimed tips auto-refund. Built for a hackathon with the full loop working end to end: Postgres + Redis backend, demo-mode bypasses so judges can run the flow without secrets, and an Anchor program for on-chain claim/refund.

### WatchTower

A private, read-only Solana monitoring daemon controlled entirely through Telegram. A single Rust binary on SQLite polls token prices and SOL balances, evaluates alert rules (thresholds plus %up/%down on a rolling baseline), and pushes edge-triggered notifications to admins. Well-known mints are compiled in as data so no third party can redirect a familiar symbol at a different mint.

### Receba Guard

Self-hosted USDC receivables verification for Brazilian merchants. A WhatsApp-native agent creates Solana Pay invoices while a local Rust verifier deterministically confirms on-chain settlement — correct mint, correct destination, exact amount, unique reference. The LLM interprets conversation; the verifier owns money state. No private keys, no custody.

### ChibiTown

A cozy 2D virtual town where your team hangs out together — presence without a grid of video tiles. Sign in, pick a character (Adam, Ash, Lucy, or Nancy), and drop into a shared pixel-art room where you walk around with WASD and see everyone else move in real time, complete with name labels and a live roster. Rooms are shareable by ID across themed Tiled maps — a 40×30 office and a 24×18 rooftop garden — with collision derived from the same solid layers the scene renders, so client and server agree on the playable area. Turborepo monorepo: a Vite + React + Redux + Phaser game client, an Express REST API (JWT + scrypt auth, users, spaces, avatars, maps), a WebSocket room server for presence and tile movement, and a Prisma/Postgres package, all covered by an end-to-end integration suite.

### RugPulse

Real-time Solana new-token intelligence powered by Birdeye — detect momentum, expose concentration, flag obvious risk. Pulls fresh launches from six Birdeye Data Service endpoints, enriches each with security, holder, trader, and OHLCV data server-side, then scores them with a deterministic, auditable engine: an Alpha Score (0–100) weighing liquidity, volume, trades, and momentum, and a Rug Risk Score (0–100) reading top-holder concentration plus freeze/mint authority and metadata flags straight from token_security. Every score ships with per-factor explanations and a trader-readable verdict — Watch, Caution, Avoid, or Neutral. A radar of the latest scans, per-token detail pages with charts and holder distribution, ranked leaderboards, a Telegram alert bot (@RugPulseBot) with tunable thresholds, and one-click X-post drafts. No wallet connection, no swaps — just a fast signal, and the API key never reaches the browser.

### Tipmark

A non-custodial 'Buy Me a Coffee' for Solana creators. A creator claims a handle, shares the link, and supporters tip SOL straight from their wallet to the creator's — no platform cut, no custody, no database. Ownership lives in a Solana program, profile content lives on Arweave, and every contribution has a receipt that can be rebuilt from chain. The program never holds a balance: tips validate the payout account against the profile, then CPI straight to the System Program.

### Ask Genie

A privacy-first Chrome extension (Manifest V3) that lets you chat with AI about the page you're currently reading — bring your own key, with no backend and no shared infrastructure. A floating genie lamp summons a Shadow-DOM chat panel that grounds answers in the page's extracted main content, with one-click quick actions: Summarize, Key insights, Explain simply, Action items, and Translate. Each page keeps its own conversation in local storage, auto-deleted 24 hours after it starts. Your API key lives only in the background service worker and is sent only to your chosen provider's official endpoint (OpenAI or Anthropic) — it never touches the content script or any web page. Built with Vite, React, and @crxjs/vite-plugin around a framework-free, unit-tested core for providers, page extraction, and Markdown rendering.

### Dev DNA

A cinematic GitHub profile analyzer that turns any username into a developer identity report. Fetches profile, repos, and language stats from the GitHub API, scores the user against archetype profiles, and visualizes the result through animated terminal sequences, a custom canvas language chart, and an archetype card.
