USDG Shielded Pool
🔒 Confidential[ How Offline SMS Payments
Actually Work ]
Deposit Once, Online
Fund your shielded pool a single time while you have internet. After that, every payment works fully offline.
Send by SMS
Text the amount and a phone number or Offly handle to the Offly number. The signed payload rides a single 160-character SMS over normal carrier networks.
Relay & Prove
An authenticated SMS gateway hands the payload to a pooled relayer. A ZK proof verifies ownership — the relayer pays the gas and submits onchain.
Received, Unlinkable
Funds land at a one-time stealth address in the recipient's shielded pool. Both sides get an SMS confirmation — sender, receiver, and amount stay unlinked.
