Pay for an iPhone with USDT
USDT is a dollar stablecoin, so the amount you send doesn't swing with the market between checkout and payment. VoltVault takes USDT on three networks: TRON (TRC-20), Ethereum (ERC-20) and Base. Each has its own checkout option and address. Never send USDT on one network to another network's address.
The phone
The iPhone 18 Pro Max (256GB) is $1,000, open-box and unused, never sold as factory-sealed. The iPhone 18 Pro Max crypto page covers the other coins we take, and the iPhone crypto hub covers the other models.
Step 1: Save your order
Add the iPhone to your cart, enter your delivery details and tap Save my order. You get an order reference and the exact total before you send anything.
Step 2: Choose TRON or Ethereum (or Base)
USDT on TRON (TRC-20): the address starts with T. Exchanges often charge a flat USDT withdrawal fee of roughly a dollar or a few dollars. A self-custody TRON wallet needs TRX (or energy) to pay the network fee.
USDT on Ethereum (ERC-20): sent to a 0x address and paid for in ETH gas. A token transfer on Ethereum usually costs from under a dollar to a few dollars, and more when the network is busy.
USDT on Base: the same 0x address format as Ethereum but a separate checkout option. It usually costs a few cents. Pick Base only if your wallet or exchange actually sends on Base.
These fees are approximate and change all the time. Your wallet's send preview shows the real figure.
Step 3: Send and place the order
Copy the address from the checkout page itself and check it against our verify page. Make sure the amount the recipient gets matches the total after any exchange fee. Send it, keep the transaction hash, then go back to checkout and tap Place my order. We confirm the payment on-chain and ship.

Can I send TRC-20 USDT to the Ethereum address?
No. Pick the TRON option and use its address. Sending on the wrong network can lose the funds, so contact us before doing anything if it has already happened.
