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 Optimism, Ink, Plasma, Conflux, HyperEVM, Unichain, X Layer, Flare and Tempo the token is USDT0, not plain USDT.
day or so to credit (manual review)
We verify the on-chain transaction ourselves and credit it by hand; the recharge page states about one day.
What this channel is for
Yes: USDT sent to QCode is credited to your balance in USD, and once you buy a plan you can use it in Claude Code. USDT is the most widely distributed stablecoin, supported by essentially every exchange and wallet, so if your funds already sit there it is the most direct way to top up. The QCode dashboard lays the flow out in three steps: top up, buy a plan, start using it. The balance does not remember which coin funded it and works for Claude Code, Codex and the Chinese models alike.
Which USDT networks are live
As of 2026-10-26 USDT is open on eighteen networks: Tron, Solana, Arbitrum One, Polygon, Avalanche C-Chain, Ethereum, TON, Sei and Aptos, plus Optimism, Ink, Plasma, Conflux, HyperEVM, Unichain, X Layer, Flare and Tempo, which carry USDT0. Deposit addresses are issued per asset and network, shown only on the recharge page after you sign in, and are not interchangeable. If you hold USDC instead, that works too, also on 18 networks.
Three steps
Sign in and open the recharge page at qcode.cc/recharge, choose USDT under crypto on the USD tab, then pick the network your USDT actually sits on; the page shows the deposit address for that exact asset and network. Send 2-3% more than the USD price on the pricing page, and start with a small test transfer.
Send from your wallet or exchange with exactly the network chosen on the recharge page. Manual crypto top-ups have no submit button, so report the transfer yourself: coin and chain, amount in USD, transaction hash, and your QCode ID or registered email, via live chat or hi@qcode.cc. Your QCode ID is shown in the user bar at the top right of the dashboard.
Once verified, the dashboard shows 'Balance received — You can activate a plan now.' Go to qcode.cc/subscribe and pick a recommended plan or a custom configuration, paid from your balance; the confirmation reads 'Subscription Activated — Your API Key is created and ready to use', and you copy the key starting with cr_ into Claude Code.
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 and Polygon are cheap L2s with good wallet support. Those four cover almost every case.
Where people go wrong
First, nine 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. The trade-off is manual verification, usually within a day rather than instant.
Credit card
Instant and fully automated, but it 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. Send at least the equivalent of ten US dollars per transfer, and never less than the exchange-side minimum deposit of 2.5 USDT. QCode verifies the on-chain transaction itself instead of using a third-party crypto gateway, so there is no processing fee and the full verified USD amount is credited; any balance left after buying a plan is not wasted and can go toward an upgrade or a booster pack later. If you would rather not pay monthly, Pay-as-you-go Packs start at $4 for a one-time quota you use within 7 days (top-ups start at $5). If you already have a Personal Plan and run short, buy a booster pack; if you have no plan, buy a Pay-as-you-go Pack.
What the balance covers
The balance is held in USD and billed per token; per-model rates are listed on /models, and crypto-funded balance is not tied to any subset of models. In Claude Code, set ANTHROPIC_BASE_URL to https://api.qcode.cc/api and put your cr_ key in ANTHROPIC_AUTH_TOKEN to call claude-opus-5-5, claude-sonnet-5-5, claude-haiku-5-5 and more; the same key also calls gpt-6.1-sol in Codex (base_url https://api.qcode.cc/openai) and Chinese models such as deepseek-v4-pro, glm-5.3 and kimi-k3. Not ready for a monthly plan? Pay-as-you-go Packs start at $4 for a one-time quota you use within 7 days (top-ups start at $5).
Frequently asked questions
Which chain has the lower transfer fee 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 or Polygon, using that chain saves you a bridging step. On Optimism only USDT0 is accepted: legacy bridged USDT sent there cannot be credited, so check that your wallet holds USDT0 before you send.
What is the difference between USDT0 and USDT?
USDT0 is the cross-chain build of Tether, circulating on Optimism, 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, otherwise the on-chain fee eats too large a share. Separately, each asset has an exchange-side minimum deposit, 2.5 USDT for USDT; transfers below it may not be credited. That one is a hard threshold, and both apply.
How long until USDT is credited and I can use Claude Code?
Crypto is verified by hand, which the recharge page puts at about a day; once the balance lands, buy a plan and your key is created on the spot, so you are in Claude Code within minutes. If the transfer stays pending on-chain for more than an hour, contact support with the transaction hash. If you are in a hurry, pay by card instead, which is credited as soon as the payment completes.
What if I forget to tell you about the transfer?
Manual crypto top-ups have no submit button; the transfer is matched to your account only once you report it. If you forgot, contact live chat or hi@qcode.cc with the transaction hash (txid), coin, network and amount. Without a txid it cannot be traced, and the credit simply arrives later.
Where this page gets its facts
Payment details on this page come from the Payment Methods overview (updated 2026-10-19), the Crypto Payment Guide (updated 2026-10-15) and the Dashboard Guide on docs.qcode.cc, plus the Pay-as-you-go Packs page (qcode.cc/pay-as-you-go); payment methods and pack terms were checked on 2026-10-19, and the recharge page you see after signing in stays authoritative for networks and tokens. On-chain fees are set by each network in real time and have nothing to do with QCode.
Start topping up with USDT
Sign up for QCode, pick the chain your USDT is already on, and start calling Claude Code shortly after.
