Paying with USDT without an exchange account

A wallet you control signs the transfer itself, so no account sits behind the payment. What that changes, what it does not, and the one thing we never ask for.

The direct answer: paying from a wallet you control does not require an exchange account, because the transfer is signed by your key and settled on-chain, and the invoice on our side only watches one address for one exact amount on one network. What we never ask for, and would have no use for, is your seed phrase. Anyone claiming to be this shop who asks for a twelve- or twenty-four-word phrase is not this shop.

What self-custody actually means

You hold the keys. The address belongs to a wallet application on your device, and the balance exists on the chain rather than inside someone's ledger. Nothing in the transfer depends on an intermediary approving it, which is why the payment either matches the invoice or it does not, with no third party in the middle to ask.

On our side there is no name, no email address and no identity document to see. No email is sent by this shop at all, and there is no card or bank data on file that could leak.

What it does not change

• Acquiring crypto is a separate step. Turning money into a stablecoin normally happens somewhere that has its own obligations toward you, and those are between you and that service. A self-custody wallet does not cancel another party's requirements, and this page is not advice on evading a duty someone is legally required to impose on you.
• Nothing about the subscription changes. It is one month, applied to your own account, with the limits that plan already carries.
• Network fees still exist. You pay them, on top of the invoice amount rather than subtracted from it.

The risks, stated plainly

Self-custody is not safer. It is less mediated, and that trade cuts both ways.

• Lose the seed phrase and there is no support line to call. Nothing in this shop can restore a wallet we never had access to.
• A wrong address is final. Check the network before signing, because USDT on the wrong chain is the most common broken order here.
• Backup prompts, phishing pages and fake wallet updates are the actual loss mechanism in this category. Confirm where the application came from before putting a key in it.
• Send a small test transfer first if the amount is worth caring about. That costs one fee and removes a whole class of disaster.

What we do need

Two things, and both describe the order rather than you. The account identifier: the Claude Organization ID from Settings, then Account, starting with org_, or the ChatGPT session token from chatgpt.com/api/auth/session, which expires on its own. And after paying, the transaction hash together with the order number, which is the only receipt that exists. A value starting with sk- is an API key and opens nothing.

Payment covers USDT and USDC plus native TRX, SOL and TON across eight networks. ChatGPT Plus is 95 CNY, about 13 euro; Claude Pro is 105 CNY, about 14 euro; both are one month. If a transfer lands on the wrong chain or with the wrong amount, it is reconciled by hand, case by case, outside the standard refund policy, so raise it immediately instead of waiting.

Asset choice is in USDT or USDC, the field-by-field walkthrough is in how to pay with USDT, and what you keep as proof is covered in what receipt a crypto purchase gives you.
