Four numbers worth knowing

networks to choose from

Tron, Solana, Arbitrum, Aptos, TON and more — pick whichever chain your USDT already sits on.

platform fee

No third-party crypto gateway, so the full USD value of what you send reaches your balance.

networks carry USDT0

On Ink, Plasma, Conflux, HyperEVM, Unichain, X Layer, Flare and Tempo the token is USDT0, not plain USDT.

day to credit

We verify the on-chain transaction and credit by hand, usually within a day and faster during business hours.

What this channel is for

Plenty of developers cannot get a card that works with overseas AI services, or would rather their API spend did not show up on a card statement. USDT is the most widely distributed stablecoin, supported by essentially every exchange and wallet. Once it is in your QCode balance it works across Claude Code, OpenAI Codex, Gemini and everything else on offer — the balance does not remember which coin funded it.

Which USDT networks are live

Eighteen right now: Tron, Solana, Arbitrum One, Polygon, Optimism, Avalanche C-Chain, Ethereum, TON, Sei and Aptos, plus Ink, Plasma, Conflux, HyperEVM, Unichain, X Layer, Flare and Tempo which carry USDT0. Each network has its own deposit address on the recharge page and they are not interchangeable.

Three steps

Step 1

Check the USD price of the plan you want on the pricing page and convert it to USDT at the current rate. Adding 2-3% covers on-chain fees and rate movement.

Step 2

Sign in, open the recharge page, choose USDT, then choose the network your USDT actually sits on. The page shows the address and QR for that exact network.

Step 3

Once the transfer is out, send us the network, amount, on-chain transaction hash and your QCode ID by email or Telegram. We verify and credit the balance.

Two things to check before picking a network

The mainstream networks

Tron (TRC20) is the most widely supported and cheap, which makes it most people's default. Solana is faster and cheaper still. Arbitrum One, Polygon and Optimism are cheap L2s with good wallet support. Those five cover almost every case.

Where people go wrong

First, eight of the networks carry USDT0 rather than plain USDT; the two are not interchangeable and a wrong send cannot be recovered. Second, Ethereum mainnet (ERC20) has the highest fees, so unless your USDT is already there it is rarely worth it. Third, every network has a different deposit address — always use the one the recharge page shows you, never a reused one from a past transfer.

USDT versus paying by card

USDT (this page)

Zero platform fee and the full amount reaches your balance. No overseas card needed. The trade-off is manual verification, usually within a day rather than instant.

Credit card

Instant and fully automated, but it carries a processing fee and needs a card that overseas AI services will actually accept.

Getting the amount right

USDT is not permanently pegged at exactly one dollar, exchanges quote slightly different rates, and the on-chain fee comes out of the transfer, so what arrives is often a little under the number you typed. The safe habit is to send 2-3% above the USD figure from the pricing page. Anything extra is credited too, so nothing is wasted.

What the balance covers

The balance is denominated in USD and works across every model QCode carries: the full Claude Code line, OpenAI Codex, Gemini, and the Chinese families such as GLM, Kimi, DeepSeek and Qwen. There is no rule tying crypto-funded balance to a subset of models. See the pricing page for what is currently on offer and at what rate.

Frequently asked questions

Which chain is cheapest for USDT?

Tron (TRC20) and Solana usually have the lowest transfer fees and are the easiest to withdraw to from most exchanges. If your USDT already sits on an L2 such as Arbitrum, Polygon or Optimism, using that chain saves you a bridging step.

What is the difference between USDT0 and USDT?

USDT0 is the cross-chain build of Tether, circulating on Ink, Plasma, Conflux, HyperEVM, Unichain, X Layer, Flare and Tempo. It is a different token from plain USDT and the two cannot substitute for each other. The recharge page labels these networks explicitly.

Is there a minimum?

We suggest at least the equivalent of ten US dollars per transfer. Below that the on-chain fee eats too large a share to be worth it. The recharge page is authoritative on the current threshold.

How soon can I start using Claude Code?

As soon as the balance lands. That depends on manual verification, which usually completes within a day of your report and faster during business hours. If you need it immediately, the card and Alipay channels settle instantly.

What if I forget to tell you about the transfer?

We cannot work backwards from an on-chain transaction to the account that sent it, so we rely on your transaction hash and QCode ID to match them up. If you forgot, just send the details afterwards — nothing is lost, the credit simply arrives later.

Where this page gets its facts

The networks and token builds listed here come from the same configuration that drives the recharge page and update alongside it. Fee comparisons are general guidance; the actual on-chain fee is set by the network in real time and has nothing to do with QCode.
