Orinx on Arbitrum 🔒

The Privacy Layer for the EVM Era.

Orinx allows users to receive, hold, and send funds onchain while protecting their financial privacy.

🔐 Orinx at a Glance

• Zero-Trust Architecture: Privacy guarantees remain intact even if the blockchain, frontend, or all external infrastructure are fully observable.

• Client-Side Privacy: All sensitive cryptography and key derivation happens locally.

• Non-Custodial: Keys never leave the user’s device.

• Recoverable: Funds can always be recovered directly from the chain without Orinx UI.

• Auditable: Users can selectively disclose transaction history when required.
  

⚡ TL;DR

Orinx brings private payments to Arbitrum using stealth addresses. Stay non-custodial, avoid pooled funds, and keep every transaction unlinkable.

"Privacy is not about hiding bad things. It's about protecting good people."

🚫 The Problem: The Glass House

Blockchains are architectures of surveillance.

By default, every transaction you make—payments, salary, medical bills, donations—is broadcast to the world forever. Standard wallets don't just leak your data; they dox your entire financial life to:

• Ad Tech: Building profiles of your net worth and spending habits.

• Bad Actors: Targeting you for phishing or extortion based on your balance.

• Competitors: Monitoring your business's cash flow and supply chain.

Real finance requires confidentiality. Orinx bridges the gap between transparent chains and the privacy we need.

🕶️ The Solution: Cryptographic Privacy

Orinx is an on-chain privacy protocol that brings Stealth Addresses to Arbitrum.

We decouple your Public Identity from your On-Chain Assets.

1. Public Identity (The Meta-Address): You share a single, static ID (e.g., alice@orinx). Think of this as a public instruction manual. It tells people exactly how to generate a unique address for you, without you needing to be online.

2. Private Settlement: When Bob pays you, the protocol mathematically derives a unique, unlinked address just for that payment.

3. Unified Dashboard: Orinx aggregates all these scattered addresses into a single view. To you, it looks like one balance. To the blockchain, it looks like thousands of unrelated wallets.

🔥 Key Features

1. Fortress-Level Security 🏰

Orinx acts like a Hardware Wallet inside your browser.

• Isolated Execution: All sensitive cryptography (signing, derivation) happens locally.

• Zero Leakage: Your private keys NEVER leave your device. The UI "views" your balance but cannot touch your keys.

• "Scorched Earth" Policy: If you close the tab, the keys are wiped from memory instantly. Nothing is persisted.

2. Smart 2FA (Identity Binding) 🔐

Your seed phrase isn't enough. Standard wallets have a fatal flaw: if someone steals your seed phrase, your money is gone.

Orinx implements Identity Binding:

• We bind your wallet keys to a PIN/Password using high-hardness cryptography.

• The Result: Even if an attacker steals your 12-word phrase, they cannot access your Orinx funds without your 2FA PIN/Password.

• It is a cryptographic second factor, meaning your wallet address cannot be derived without your PIN.

3. Stealth Forwarding 🔄

Move funds from one stealth address to another—without ever touching a public exchange.

• Pay a supplier, a friend, or an employee directly from your unlinked private balance.

• The transaction remains mathematically unlinked.

4. Manual Recovery ("The Safety Net") 🚨

We believe in "Trust, but Verify". Orinx is non-custodial.

• Missed a scan? The Manual Recovery tool scans the entire blockchain history to find your funds.

• Even if our indexer goes down, your funds are always recoverable directly from the chain.

5. Privacy 📕

• Even we (the developers) cannot see who you know and paid.

🚀 Why Arbitrum?

Orinx + Arbitrum is the perfect combination for the next generation of privacy-preserving applications.

1. Instant Finality (Low Latency) ⚡

Privacy usually means "slow" (waiting for mixers or ZK provers). On Arbitrum, stealth payments feel instant. This low latency is critical for physical Point-of-Sale (POS) and high-frequency use cases.

2. Micro-Transaction Ready (Low Cost) 🪙

Traditional privacy layers are too expensive for small payments. Arbitrum's ultra-low fees allow Orinx to support tipping, gaming rewards, and micro-subscriptions privately—use cases that were previously impossible.

🎯 Arbitrum Focus Tracks

Orinx is built to accelerate the adoption of Privacy across key Arbitrum verticals.

1. Stablecoin Payments & Financial Infrastructure 💸

Privacy is the missing piece of financial infrastructure. Businesses and individuals need to transact in stable assets (USDC, USDT, EURC) without exposing their entire net worth or supply chain.

• Stablecoin Native: Orinx supports private transfers of any ERC-20 token on Arbitrum.

• Payroll & Settlements: Enable private salary payments in USDC.

• Merchant Payments: Accept crypto for goods/services without doxxing your business treasury.

2. Gaming & Consumer Applications 🎮

We bring "Web2 Usability" to Web3 Privacy.

• Gaming Guilds: Pay scholars and tournament winners privately to prevent on-chain sniping or targeting.

• Seamless Onboarding: Our Username System (alice@orinx) replaces 42-character hex strings, making crypto accessible to non-technical users.

• Identity Layer: A portable privacy layer that can settle payments for any consumer dApp on Arbitrum.

🏗️ Technical Architecture

Orinx is built on a "Trust Nothing" architecture.

🛡️ Threat Model

Orinx is designed under a zero-trust threat model. The blockchain and frontend are treated as untrusted, and privacy guarantees must hold even if all infrastructure except the client’s local worker is fully observable.

📊 Privacy Landscape

Unlike mixers (e.g. Tornado Cash) or ZK wallets, Orinx avoids pooled funds and prover overhead.

✅ Transparency & Trust (Arbitrum Deployment)

We believe privacy tools must be open and verifiable.

⚖️ "Good Actor" Compliance

Orinx is designed for legitimate privacy, not illicit evasion.

• Auditable Privacy: Need to prove a payment for tax or audit purposes? Orinx allows you to export your transaction history in one click.

• Selective Disclosure: You are in control. You can reveal specific transactions to counterparties or regulators without doxxing your entire financial life.

• Non-Custodial: We never hold your funds.

🎯 Who Is Orinx For?

• Freelancers: Receiving salary in USDC without clients tracking their net worth.

• Founders: Paying for operational expenses without leaking runway data.

• Traders: Keeping alpha strategies private from copy-traders.

• Crowdfunding: Raising funds for a sensitive cause without exposing every donor's identity.

• Friends & Family: Splitting dinner bills or sending gifts without revealing your main wallet balance.

❓ FAQ

• Q: Which wallets is Orinx compatible with?

  A: Orinx works alongside your existing wallet. It is compatible with MetaMask, Rainbow, Coinbase Wallet, and any WalletConnect-enabled wallet.

• Q: Is Orinx meant to hide illicit activity?

  A: No. Orinx is designed for legitimate financial privacy. It is non-custodial and supports selective disclosure.

• Q: Can I use Orinx for taxes and accounting?

  A: Yes. You can export your full transaction history in one click.

Built by founders, for the future.
Secure. Private. Unstoppable.

Over the course of the hackathon, we conceptualized and built the complete Orinx protocol from scratch:

1. Smart Contract Infrastructure (Deployed): We wrote and deployed a modular, zero-state smart contract architecture to Arbitrum Sepolia.

   • OrinxRegistry.sol (Identity Layer): Maps @usernames to a user's stealth Meta-Address, acting as a public instruction manual.

   • OrinxAnnouncer.sol (Stateless Payment Layer): Handles the secure flow of funds and emits encrypted event logs. It holds no user state, maximizing gas efficiency.

2. Zero-Trust Client Architecture: We built a "hardware wallet in the browser".

   • All cryptography (key derivation, signing) is executed entirely client-side using @noble/secp256k1.

   • We implemented a "Scorched Earth" memory policy where keys never leave the device and are wiped instantly upon closing the tab.

3. Arbitrum Integration: We specifically optimized for Arbitrum to enable instant stealth payments and low-cost micro-transactions—two critical barriers that previously prevented privacy layers from reaching consumer adoption.

We haven't raised any funds yet; this project was entirely built out of our passion for on-chain privacy. We would love the opportunity to secure backing and officially become one of the 'Privacy Pioneers' pushing this space forward.
