Follow the official docs to add credit with USDT on TRC20: create an order, transfer the exact unique amount to the returned address, then confirm the status. USDC follows the console. Not for mainland China.
You add wallet balance before buying dynamic residential traffic or a static residential IP, and before you renew a static IP. Pricing states that USDT and USDC are accepted, and that Visa and Mastercard are still being applied for. The official docs currently describe USDT TRC20 top-up in detail: create a top-up order, transfer to the returned address and amount, then check whether a matching on-chain payment is confirmed. This page follows that flow. It does not claim that other networks or card payments are already live.
If the console has a top-up entry, follow the labels on screen. For USDC, use the network and arrival rules shown in the console; this page does not invent a USDC contract or API. Example amounts are not a quote. Use this only to fund an account you are allowed to operate. Not supported in mainland China.
What to prepare
| Item | Where it comes from |
|---|---|
| A signed-in ZTProxy account | The console, or the API with a token kept on the server; see Authentication |
| A wallet that can send USDT | A wallet you control; send only to the address returned for that order |
| The network and amount on the order | The documented API is USDT TRC20. Address, rate, and minimum amount come from wallet info or that order |
| The product you will buy next | Dynamic traffic in GB or static IPs per month; start with GB vs IP pricing |
This page has no code block. API details stay in the docs. Do not treat a sample rate or sample address in the docs as the current payee.
A recommended check sequence
- Open top-up in the console, or fetch wallet info as documented. The response includes the payee address, network, currency, current rate, and minimum amount. Trust the current console or API return, not an example.
- Create a top-up order. The documented amount field is a RMB amount, `amount_cny`, which must be greater than 0 and at most 50,000 per order. The system generates a unique USDT amount so pending orders are not confused with one another. Transfer that exact amount; do not round it to a whole number.
- Send USDT only to the address on that order, on the stated TRC20 network. Do not use a different network, and do not reuse an address or amount from an older order.
- Check top-up status, or refresh the order in the console. Documented statuses are in the table below. When you query status, the system looks for a matching on-chain transfer; a match confirms the order and increases the user balance.
- Query balance and transactions again, confirm the amount arrived, and only then place or renew an order.
| Status | Meaning | What you can do |
|---|---|---|
| `pending` | Waiting for payment confirmation | Wait for an on-chain match; only this status can be cancelled, as documented |
| `confirmed` | Confirmed, and the system has increased the user balance | Re-check the balance, then buy resources |
| `cancelled` | Cancelled | Do not send funds to that order address; create a new order if you still need credit |
The current account can only see top-up orders inside its permission scope. Do not post payee addresses in public channels.
How to avoid a mismatch after you transfer
| Situation | Check first |
|---|---|
| The order stays pending | Whether you used TRC20; whether the amount matches the order exactly; whether you used that order's address; whether chain confirmation is still in progress |
| You sent a rounded or slightly different amount | Matching relies on the unique amount; changing it can prevent confirmation |
| You used another network or an old address | This page cannot promise recovery; stay with the current order, and contact support with the order number if needed |
| You want to pay in USDC | Pricing says USDC is accepted, but the detailed documented API is USDT TRC20. Read the console for USDC and do not reuse this TRC20 sequence |
| You want to pay with Visa or Mastercard | Pricing says those cards are still being applied for; do not describe card checkout as live |
After the balance arrives, dynamic traffic and static IPs are still purchased separately. To read remaining dynamic traffic, see remaining traffic.
Scope and compliance
Use this only to fund an account you are allowed to operate. This is not a bypass or anonymity guide. Prices follow the console and Pricing (dynamic about $0.40/GB, about $0.20/GB on the 100 TB package; shared static about $1.50 and dedicated about $5 per IP per month). USDT and USDC are accepted; Visa and Mastercard are still being applied for. Not supported in mainland China.
FAQ
Can I top up with a credit card today?
Pricing says Visa and Mastercard are still being applied for. Do not describe card payments as a live capability.
Does USDC follow this same TRC20 article?
Not necessarily. Pricing says USDT and USDC are accepted. The detailed official docs describe USDT TRC20. For USDC, follow what the console shows, and do not invent a network.
Why must I send the exact USDT amount on the order?
The docs say the system generates a unique amount so pending orders can be matched. Rounding it to a whole number may prevent automatic confirmation.
Where do the minimum amount and rate come from?
From the current wallet-info response or the console. Do not use a sample rate in the docs as the live price.
Can I cancel a pending order?
The docs say only orders in `pending` can be cancelled. Do not send funds to an order that is already confirmed or cancelled.
Does a successful top-up provision a proxy automatically?
No. A top-up increases wallet balance. You still need to buy dynamic traffic or a static IP, or renew an existing static order.
Can I use this to fund someone else's unrelated account?
This page only covers funding an account you are allowed to operate. Permission scope follows the account and the docs.
Which price should I trust?
The console and Pricing. If a self-serve signup is attached to an agent, actual charges follow that agent's price.
Next steps
- Create a top-up order and transfer on the returned network, address, and exact amount.
- Wait until the status is confirmed, then re-check the balance.
- Buy dynamic traffic or a static IP, or renew an existing static order.
