Support & anti-fraud guide

How to confirm you're on the real checkout

1. Type your brand domain (or Punycode) in the mobile browser address bar and confirm a 302 redirect to the bank's official H5 domain.
2. Tap the lock icon and verify the TLS certificate is issued to a licensed bank or payment institution—not an individual or unknown entity.
3. View page source and compare Punycode with registry WHOIS records to prevent homograph phishing.

Binding workflow

1. Log in to the merchant portal, pass the slider captcha, and submit your domain and checkout URL.
2. Point your domain CNAME to 302wallet.com—see the CNAME guide.
3. If micro-payment verification isn't feasible, use the TXT verification guide.
4. Complete the micro-payment verification on your existing checkout as instructed.
5. Enter the exact amount shown on the receipt in the portal; once activated, routing syncs to resolver nodes automatically.

Changes or unbinding

Binding records cannot be modified. To change a checkout URL, complete 2FA verification, delete the old record, and create a new binding. Never delegate DNS control to untrusted third parties.
