When integrating with Phantom, you need to verify your domain to be able to use Phantom Connect SDK and for your app to appear in Phantom’s Explore tab and search results. Verification proves you control the domain and helps protect users from phishing.

​
Domain verification process

​
Step 1: Enter your domain

  1. In Phantom Portal, go to Edit App Info.
  2. Find the Public URL field.
  3. Enter your app’s primary domain (https://yourapp.com).
  4. Select Save.
Use only your root domain or primary subdomain. Do not include paths such as /app or /dashboard.

​
Step 2: Get your verification code

  1. After entering your domain, find the Domain Verification section.
  2. Copy the verification code shown (format: phantom-verification-XXXXX)

nslookup -type=TXT yourapp.com
Or using online tools:

​
Step 5: Complete verification in Phantom Portal

​
Maintain verification

Keep the DNS TXT record in place. If you remove the record, your verification will be revoked, your app may be removed from public listings, and you will need to re-verify your domain.

​
Troubleshooting

​
Verification fails

Problem: Selecting Verify Domain shows an error. Solutions:
  • Wait for full DNS propagation (up to 48 hours)
  • Confirm that the TXT value matches exactly
  • Remove extra quotation marks from the value
  • Ensure the record is at the root domain (@)
  • Try another DNS checker
  • Clear your local DNS cache:
# macOS
sudo dscacheutil -flushcache

# Windows
ipconfig /flushdns

​
Multiple TXT records

Problem: Your domain already has TXT records. Solution: You can have multiple TXT records. Add the Phantom verification code as a new record. Do not replace existing records.

​
Subdomain or root domain

Problem: Unsure which domain to verify. Solution: Verify the domain where users access your app:
  • If your app runs at app.example.com, verify that subdomain
  • If your app runs at example.com, verify the root domain

​
DNS changes not saving

Problem: DNS provider won’t save your changes. Solutions:
  • Remove quotes around the TXT value
  • Ensure there are no trailing dots
  • Confirm you have permissions to make changes
  • Contact your DNS provider

​
