Getting Started: Account Creation & Security

Creating a secure Dark Matter Market account requires several steps to ensure maximum protection:

Account Registration Process:

  1. Access the official Dark Matter site using verified .onion links from our links page
  2. Click "Register" on the main navigation menu
  3. Create a unique username that you've never used elsewhere (avoid personal identifiers)
  4. Generate a high-entropy password (minimum 16 characters with mixed case, numbers, and symbols)
  5. Complete the anti-bot CAPTCHA verification to prove you're human
  6. Save your recovery mnemonic phrase in a secure offline location (ideally handwritten)
  7. Configure PGP-based two-factor authentication for critical account actions

Critical Security Warning: Your mnemonic recovery phrase is the only way to regain access if you lose your password. Write it down on paper and store it securely. Never save it digitally or take screenshots of it. If someone obtains this phrase, they gain complete access to your account.

Setting Up PGP for Enhanced Security:

PGP (Pretty Good Privacy) is essential for secure communications and account protection:

  1. Install a PGP tool like Kleopatra (Windows), GPG Suite (Mac), or GnuPG (Linux)
  2. Generate a new key pair with 4096-bit RSA encryption
  3. Set a strong passphrase for your private key
  4. In your Dark Matter account settings, navigate to "Security"
  5. Paste your public PGP key in the provided field
  6. Complete verification by decrypting the test message
  7. Enable PGP 2FA for all sensitive account actions

Pro Tip: Using a dedicated encrypted operating system like Tails or Whonix provides additional security layers for your marketplace activities. Dark Matter Academy offers a complete course on secure OS configuration.

✓Security Checkpoint

Before proceeding, ensure you have:

  • Created an account with a unique username and strong password
  • Stored your recovery mnemonic phrase securely offline
  • Set up PGP for encrypted communications
  • Enabled two-factor authentication for account protection
  • Configured anti-phishing phrase in your security settings
2

Funding Your Account Securely

Dark Matter Market exclusively uses Monero (XMR) for all transactions due to its superior privacy features:

The Proper Monero Acquisition Flow:

  1. Obtain Monero (XMR) through one of these methods:
    • Exchange BTC or other cryptocurrencies for XMR on non-KYC exchanges
    • Use peer-to-peer trading platforms that support XMR
    • Purchase through privacy-respecting ATMs (where available)
  2. Transfer to a personal Monero wallet - recommended options:
    • Feather Wallet (desktop)
    • Cake Wallet (mobile)
    • Monero CLI/GUI (advanced users)
  3. Navigate to your account dashboard after logging into Dark Matter
  4. Select "Deposit Funds" from the account menu
  5. Generate a unique one-time deposit address (never reuse old addresses)
  6. Send XMR from your personal wallet to the generated address
  7. Wait for network confirmations (typically 10-20 minutes)
  8. Verify funds appear in your Dark Matter account balance

Critical Privacy Warning: Never send funds directly from exchanges to Dark Matter. Always use an intermediate wallet with proper transaction security (subaddresses, different ring sizes) to maintain chain-of-custody separation.

Understanding Monero Transaction Privacy:

Monero transactions offer significant privacy benefits over Bitcoin and other cryptocurrencies:

  • Ring Signatures: Obscure the true source of funds by mixing your transaction with others
  • Stealth Addresses: Generate one-time addresses for each transaction
  • RingCT: Hide transaction amounts from blockchain observers
  • Bulletproofs: Efficient zero-knowledge range proofs that enhance privacy

Wallet Security Tip: For maximum privacy, configure your Monero wallet to use Tor for connecting to remote nodes, or better yet, run your own Monero node if possible. This prevents IP leakage during transactions.

✓Funding Checkpoint

Before proceeding to shopping, verify that:

  • You've acquired XMR through privacy-respecting channels
  • You've transferred funds through a personal wallet (not directly from an exchange)
  • You've sent XMR to a freshly generated Dark Matter deposit address
  • Your deposit has received sufficient network confirmations
  • Your account balance reflects the correct amount

Browsing & Ordering Products

Dark Matter Market features an intuitive interface for finding products and completing purchases:

Effective Product Discovery:

  1. Browse product categories using the main navigation menu
    • Products are organized into major categories with nested subcategories
    • Use filters for shipping origin, destination, and vendor metrics
  2. Use the search function with specific keywords and advanced search operators
    • Syntax: keyword1 keyword2 vendor:name price:<100 ship_from:country
    • Use quotes for exact phrases: "exact phrase search"
  3. Review vendor profiles before considering their products
    • Check rating metrics, longevity, and transaction history
    • Read recent customer reviews with particular attention to negative feedback
    • Verify PGP keys match those in the vendor's signed profile
  4. Examine product listings thoroughly
    • Read full product descriptions, shipping policies, and refund terms
    • Check product-specific ratings separate from vendor overall ratings
    • Review sample photos if available (with caution for EXIF data)

The Walletless Ordering Process:

Dark Matter's innovative walletless payment system eliminates central deposit vulnerabilities:

  1. Add desired items to your cart and proceed to checkout
  2. Enter shipping details using PGP encryption (vendor's public key is used automatically)
  3. Select shipping options and additional preferences
  4. Review order summary for accuracy before final confirmation
  5. Receive unique multisig address generated specifically for this transaction
  6. Send exact XMR amount from your wallet to the provided multisig address
  7. Wait for blockchain confirmation (status updates automatically)
  8. Order processing begins once payment is confirmed
  9. Track order progress through your dashboard or order-specific page

How Walletless Payments Work: Unlike traditional marketplaces where you deposit funds into a market-controlled wallet, Dark Matter's system creates a unique multisig address for each transaction. Your funds remain in the multisig escrow until the order is completed, without ever being held in a central market wallet. This eliminates the risk of market exit scams where operators disappear with deposited funds.

Order Tracking & Communication:

After placing an order, you can:

  • Track order status through your account dashboard
  • Communicate with vendors via encrypted messaging
  • Provide shipping updates or address clarifications as needed
  • Request order extensions if delays are anticipated
  • Finalize transactions upon successful delivery

Important: Always encrypt sensitive communications using the vendor's PGP key. Never send shipping information or personal details in plaintext messages, even within the market's messaging system.

✓Ordering Checkpoint

Before finalizing your first order, ensure you've:

  • Thoroughly researched vendors and products
  • Properly encrypted your shipping information
  • Sent the exact payment amount to the unique multisig address
  • Confirmed the payment transaction in your Monero wallet
  • Received order confirmation and tracking information

Understanding XMR Multisig Protection

Dark Matter's native Monero multisig escrow system is revolutionary for darknet marketplaces, providing cryptographic security for all transactions:

How Multisig Escrow Works:

  1. Key generation: When an order is created, three cryptographic keys are generated:
    • Buyer key
    • Vendor key
    • Market administrator key
  2. 2-of-3 multisignature address is created requiring signatures from two of the three parties
  3. Buyer sends funds to the multisig address where they're securely locked
  4. Normal completion: Buyer and vendor both sign to release funds after successful delivery
  5. Dispute resolution: If conflicts arise, market admin signs with either buyer or vendor based on evidence

Security Benefits of Multisig:

This system provides significant advantages over traditional market escrows:

Traditional Market Escrow Dark Matter Multisig Escrow
Market holds all funds centrally Funds locked in cryptographic multisig contract
Vulnerable to exit scams Market can't unilaterally access funds
Market can freeze/steal funds 2-of-3 signatures required for any movement
Single point of failure Distributed security model
Escrow relies on trust Escrow enforced mathematically

Dispute Resolution Process:

If issues arise with an order, the dispute system uses the multisig architecture:

  1. Open dispute from your order page with detailed explanation
  2. Provide evidence supporting your position (screenshots, timestamps, etc.)
  3. Vendor responds with their perspective and evidence
  4. Administrator review of all submitted materials
  5. Resolution decision based on marketplace rules and evidence
  6. Signature execution with admin signing alongside buyer or vendor

Advanced Feature: Dark Matter Academy offers an interactive "Multisig Simulator" where you can practice creating and resolving multisig transactions in a sandbox environment before handling real funds.

✓Multisig Checkpoint

Make sure you understand these key multisig concepts:

  • Funds are locked in a 2-of-3 signature contract requiring multiple parties
  • Neither the market nor vendor can access funds without your signature (or a dispute)
  • You should only finalize (sign) when you've received and verified your order
  • Disputes require clear evidence and documentation for successful resolution

Accountless Anonymous Purchasing

For maximum privacy, Dark Matter offers a unique accountless purchasing system allowing transactions without creating persistent user accounts:

How Accountless Purchasing Works:

  1. Browse products without logging in or creating an account
  2. Select "Purchase Without Account" on the product page
  3. Generate a temporary encrypted identifier used only for this transaction
  4. Enter shipping information (encrypted directly to vendor)
  5. Receive one-time access key for order tracking (store securely)
  6. Complete payment using the standard multisig process
  7. Track order status by entering your access key in the verification portal
  8. Data self-destructs after order completion (30-day maximum retention)

Privacy Benefits:

Accountless purchasing offers several advantages for privacy-conscious users:

  • No persistent accounts linking your purchases together
  • No user database entry exists on Dark Matter servers
  • No password storage or authentication risks
  • No activity history beyond the current transaction
  • Automatic data purging after order completion
  • Minimal information storage during transaction processing

Important: When using accountless purchasing, your access key is the only way to track your order or communicate with the vendor. If you lose this key, you cannot recover order information. Store it securely until the transaction is complete.

When to Use Accountless Purchasing:

This feature is particularly valuable in certain scenarios:

  • For occasional purchases where account management is unnecessary
  • When making sensitive purchases you prefer not to associate with your regular account
  • When using a public or shared computer where persistent logins could be risky
  • When you want absolute minimum data retention for your transaction

Pro Tip: While accountless purchasing offers enhanced privacy, registered accounts provide benefits like saved addresses, vendor ratings, and dispute history. Consider using multiple accounts for different purposes rather than mixing sensitive and routine purchases under one identity.

✓Accountless Purchasing Checkpoint

When using accountless purchasing, remember to:

  • Store your one-time access key securely until order completion
  • Take screenshots or notes of important order details
  • Keep your Monero transaction details for reference
  • Check order status regularly using your access key
