How to Deposit USDT via Bitcoin Network (Omni Protocol)

Understanding USDT on Bitcoin Network

USDT (Tether) can be issued on the Bitcoin blockchain using the Omni Layer Protocol. This method leverages Bitcoin's security while enabling stablecoin transactions. Here's how it works:

Key Components:

• Omni Protocol: An open-source layer built atop Bitcoin that handles USDT transactions
• Bitcoin Addresses: Used for both BTC and USDT transfers
• Transaction Metadata: Contains USDT-specific information within Bitcoin transactions

Step-by-Step Implementation Guide

1. Generating User Wallet Addresses

/**
* Generates USDT address for users
* @param $user_id
* @return bool|string
*/
public function usdtcoin($user_id) {
  $lists = $this->usdt->getaddressesbyaccount("$user_id");
  if (count($lists) > 0) {
    return $lists[0];
  }
  $address = $this->usdt->getnewaddress("$user_id");
  if (strlen($address) != 34) {
    return false;
  }
  return $address;
}

Parameters:

• $user_id: Unique account identifier
• Returns 34-character Bitcoin-compatible address

2. Transaction Monitoring System

/**
* Retrieves transaction list filtered by address or block
* @param $txid
* @return mixed
*/
public function listtransactions($txid) {
  return $this->usdt->omni_listtransactions($txid);
}

Filters Available:

3. Transaction Data Structure

Key transaction fields include:

{
  "txid": "961400b692...",          // Transaction hash
  "fee": "0.00015762",              // Network fee
  "sendingaddress": "3KeC2J...",    // Sender's BTC address
  "referenceaddress": "18An5...",   // Recipient BTC address
  "amount": "1.00000000",           // USDT amount
  "block": 581100,                  // Block number
  "confirmations": 33               // Confirmation count
}

Automated Deposit Processing System

Scheduled Wallet Scanner Implementation

// Set to scan every 5 seconds
$id = \swoole_timer_tick(5000, function ($timer_id) {
  // Transaction processing logic
  // Validates new deposits
  // Updates user balances
});

Security Features:

• Address validation
• Transaction verification
• Double-spend prevention
• Balance update confirmation

Database Integration

Successful deposits should:

1. Record transaction details
2. Update user USDT balance
3. Log accounting entries

Best Practices for Omni-USDT Integration

1. Address Management

   • Maintain 1:1 user-to-address mapping
   • Implement address reuse policies

2. Transaction Monitoring

   • Optimal scan interval: 5-15 seconds
   • Confirmations threshold: 3+ blocks

3. Error Handling

   • Network disconnect recovery
   • Transaction validation fallbacks
