Web Wallet

The Rhino Miner Web Wallet is a secure, browser-based wallet for managing your RMC. It uses industry-standard encryption and mnemonic-based key generation, giving you complete control of your funds.

What is the Web Wallet?

The Web Wallet is a lightweight wallet that:

• Runs entirely in your web browser
• Generates wallet addresses from a 12-word mnemonic phrase
• Connects to the Rhino Miner network via API
• Never stores your private keys on any server
• Works on desktop and mobile devices

Creating a New Wallet

Step-by-Step Setup

1. Visit the Web Wallet

   • Go to wallet.rhinominer.rocks
   • Works on desktop and mobile browsers

2. Click "Create New Wallet"

   • The wallet will generate a new 12-word mnemonic phrase
   • These 12 words are the master key to your funds

3. Write Down Your Recovery Phrase

   • You'll see 12 random words displayed
   • Write them down ON PAPER in the correct order
   • DO NOT take a screenshot or save digitally
   • DO NOT share these words with anyone

4. Confirm Your Recovery Phrase

   • You'll be asked to enter some of the words to confirm
   • This ensures you wrote them down correctly

5. Wallet Created!

   • Your wallet address will be displayed
   • You can now receive RMC at this address

Understanding Your Recovery Phrase

Your 12-word mnemonic phrase is EVERYTHING:

• Complete Control: Anyone with these words controls your funds
• No Recovery Without It: If you lose these words, your RMC is gone forever
• No Customer Support Can Help: The wallet is non-custodial—only you have access
• Works Forever: These same 12 words will always generate the same addresses

Best Practices:

• Write on paper, store in a safe place
• Consider making multiple copies in secure locations
• Never type into a computer that might be compromised
• Never share via email, messaging, or photos

Restoring an Existing Wallet

If you already have a wallet, you can restore it:

1. Click "Restore Wallet"
2. Enter Your 12-Word Phrase
   • Type or paste your mnemonic phrase
   • Words must be in the correct order
   • Words must be spelled correctly
3. Wallet Restored
   • Your address and balance will appear
   • All transaction history is recovered

How the Wallet Works

Mnemonic-Based Security (BIP39/BIP32)

The Rhino Miner Web Wallet uses industry-standard cryptography:

1. BIP39: Generates your 12-word mnemonic phrase

   • Industry standard for wallet generation
   • Compatible with other BIP39 wallets

2. BIP32: Derives private/public keys from the mnemonic

   • Hierarchical deterministic (HD) wallet
   • One mnemonic generates your addresses

3. Browser-Side Generation: All key generation happens in YOUR browser

   • Private keys never sent to any server
   • Complete client-side cryptography

4. Non-Custodial: You control your keys

   • No one else has access
   • Your responsibility to secure

What This Means:

• Your private keys never leave your browser
• The wallet is completely non-custodial
• Even if the server is compromised, your funds are safe
• You have 100% control and 100% responsibility

Connection to Rhino Network

The wallet connects to a backend API to:

• Query Balance: Fetches your RMC balance from blockchain
• Get Transactions: Retrieves your transaction history
• Broadcast Transactions: Sends signed transactions to network
• Network Info: Gets current block height and stats

What the Server Sees:

• Your public wallet address (used for queries)
• Signed transactions (already sealed, can't be altered)

What the Server NEVER Sees:

• Your 12-word mnemonic phrase
• Your private keys
• Ability to spend your funds

Understanding Transactions

Transaction Lifecycle

1. Created: You click "Send" and sign the transaction
2. Broadcast: Transaction sent to network nodes
3. Pending: Waiting in mempool to be mined
4. Confirmed: Included in a block
5. Settled: After 6 confirmations (~6 minutes)

Confirmations

Each new block adds one confirmation:

• 0 Confirmations: Transaction just broadcast (unconfirmed)
• 1 Confirmation: Included in the latest block
• 6 Confirmations: Generally considered final (irreversible)

Safety Recommendations:

• Small amounts: 1-2 confirmations OK
• Medium amounts: 3-6 confirmations
• Large amounts: 6+ confirmations

Security Features

Non-Custodial Design

The wallet is completely non-custodial:

• You Control Your Keys: Private keys derived from your mnemonic
• No Server Access: Server never sees or stores your keys
• No Account: No username, password, or registration
• No Recovery Service: Only your mnemonic can restore access

Client-Side Encryption

All sensitive operations happen in your browser:

• Key derivation (mnemonic → private keys)
• Transaction signing
• Address generation

The server only sees:

• Your public address (to query balance)
• Signed transactions (to broadcast to network)

Privacy Considerations

What's Public:

• Your wallet addresses
• Your transaction history
• Your balance

What's Private:

• Your mnemonic phrase
• Your private keys
• Your real-world identity (unless you reveal it)

Privacy Tips:

• Use different addresses for different purposes
• Don't reuse addresses unnecessarily
• Be cautious linking addresses to your identity
• Remember: blockchain transactions are permanent and public

Wallet Management

Backing Up Your Wallet

Your 12-word mnemonic IS your backup:

Do This:

• Write it on paper and store securely
• Make multiple copies in different locations
• Consider a metal backup (fire/water resistant)
• Store in a safe, safety deposit box, or secure location

Don't Do This:

• Don't screenshot it (can be hacked)
• Don't email it to yourself
• Don't store in cloud services
• Don't share with anyone, ever

Multiple Wallets

You can create as many wallets as you want:

• Each has its own 12-word mnemonic
• Each has independent addresses and balances
• Use different wallets for different purposes (mining, savings, spending)

Managing Multiple Wallets:

• Keep mnemonics organized and labeled
• Store each mnemonic securely
• Log out and log into different mnemonics as needed

Troubleshooting

Balance Not Updating

Possible Causes:

• Backend server is syncing
• Network connectivity issues
• Browser cache issues

Solutions:

• Wait a few minutes and refresh
• Check your internet connection
• Clear browser cache and reload
• Verify transaction on block explorer

Transaction Not Appearing

New transactions need time:

• Takes 10-30 seconds to broadcast
• Appears in pending immediately
• Confirms in 1-10 minutes

If Still Missing:

• Verify sender used correct address
• Check block explorer for transaction
• Ensure sender's transaction confirmed
• Contact sender to verify they sent it

Can't Send Transaction

Common Issues:

• Insufficient balance (need to cover fee)
• Invalid recipient address
• Network connectivity problem
• Backend server issues

Solutions:

• Check you have enough RMC plus fee
• Verify recipient address format
• Try again in a few minutes
• Contact support if persists

Forgot Recovery Phrase

Unfortunately, there is no recovery option.

If you lose your 12-word mnemonic:

• Your funds are permanently inaccessible
• No one can help you recover them
• The wallet is designed this way for security
• Consider funds lost

Prevention:

• Write down your mnemonic immediately
• Make multiple copies
• Store in secure locations
• Never rely on memory alone

Best Practices

Daily Use

1. Check Balance Regularly: Monitor for unauthorized transactions
2. Verify Addresses: Always double-check before sending
3. Small Test Transactions: Send small amount first for large transfers
4. Keep Software Updated: Use latest browser version
5. Secure Your Device: Use antivirus, firewall, etc.

Long-Term Storage

For large amounts you won't spend soon:

1. Write Down Mnemonic: Paper backup in secure location
2. Consider Hardware Wallet: For maximum security (if supported)
3. Multiple Backups: Store copies in different locations
4. Test Recovery: Verify backup works before storing large amounts
5. Separate Hot/Cold: Use different wallets for spending and savings
