Pre-subscription Requirements
Docker Account Preparation
Existing Docker Hub account
Account email verification completed

Network Environment
Use a US Residential IP (Critical Success Factor)
Ensure IP is clean and geolocated in the US
MPChat Funds Preparation
Prepare 10-15 equivalent USDT (Docker Pro is $5/mo or $60/yr)
It is recommended to keep extra funds for verification fees
Detailed Steps
Phase 1: MPChat Virtual Card Preparation
USDT Deposit
Path: MPChat App → Wallet → Deposit - Copy USDT deposit address - Transfer sufficient USDT ($20+ recommended) - Wait for network confirmation
Apply for a US MPCard
Path: MPChat App → MPCard → Apply for New Card - Issuing Country: Must select "United States" - Card Type: Virtual Card (Instant generation) - Securely record Card Number, Expiry, and CVV
Funds Transfer
Path: MPChat App → Wallet → Transfer - From: MP Wallet (USDT) - To: MPCard (USD) - Amount: $8-10 (Including verification fees)
Phase 2: Docker Pro Subscription Process
Log in to Docker Account
Access docker.com using a US IP
Click "Pricing" or visit docker.com/pricing directly

Account displays the Pro badge; enjoy advanced features
Function Verification
Create private repos (should be unlimited)
Verify parallel build functionality
Check automated build time
