Paying with crypto.

In brief.

You buy a stablecoin — USDT or USDC, both pegged to one US dollar — at any exchange. At our checkout you select that token, place the order, and we show an address, a QR code and an exact amount. You send it. The order advances by itself, usually inside a few minutes, and the confirmation email follows unprompted.

No card is charged, nothing about you is stored, and no third-party payment script loads anywhere on this site.

Three steps, start to finish.

1. 1Buy the tokenUSDT or USDC at any exchange, funded by bank transfer or card.
2. 2Send the exact amountScan the QR or copy the address, on the network you chose.
3. 3It confirms itselfThe payment lands, the order moves on. Nothing to send us.

What a stablecoin is, briefly.

USDT (Tether) and USDC (Circle) are tokens designed to hold one US dollar of value. They do not swing like bitcoin — that is their whole purpose, and it is why we price in euro and convert only when the invoice is created.

The figure we ask for is therefore fixed and does not drift while you pay. If the invoice expires before you send, create a fresh one.

Choosing a network.

The same token exists on several networks, and they do not talk to one another. Take the one your exchange sends most cheaply — then use exactly that one when you withdraw.

One rule above all: the network chosen at our checkout and the network on your withdrawal screen must be the same word. USDT sent over Tron to a Polygon address does not arrive late — it does not arrive.

First time through.

1. Open an account at a large exchange — Kraken, Binance, Coinbase and Bitvavo all serve the EU. Verification runs from minutes to a day, so get it done before you need it.
2. Fund the account. SEPA is the cheap route and usually clears the next working day; a card is instant and typically a few percent dearer.
3. Buy USDT or USDC to the value of your order, plus a euro or two for the network fee.
4. Return here, choose Crypto at checkout, select token and network, and place the order. Address, QR and exact amount appear immediately — and again in your email, so the rest can happen on a phone.
5. At the exchange choose Withdraw, paste our address, pick the same network, and enter the amount precisely as shown — every decimal.
6. Send. Polygon and Tron usually settle within a minute. On arrival the order flips to confirmed on its own and the email is sent.

That is all of it. The second time takes roughly ninety seconds.

The five things that actually go wrong.

1. Wrong network. The most expensive error in crypto and the simplest to avoid — read the network twice before sending.
2. Rounding the amount. Matching is by exact figure to the last decimal; a rounded number waits for a person.
3. Letting the invoice expire. It stands for two hours. After that, request a new one rather than sending to an old address.
4. Sending the other token. USDT and USDC are different things — send the one you picked.
5. Paying from a service that hides the network. Some brokers and apps give you no choice. If you cannot see the network, use an exchange that shows it.

The cost.

Nothing is added for paying in crypto. The only extra is your exchange's fee to send — cents on Polygon and Tron, appreciably more on Ethereum.

Send the exact invoice figure and let the exchange take its fee on top. If it deducts the fee from the amount instead, raise the number so that what lands matches the invoice.

What we can and cannot see.

Our payment system only watches for an amount arriving at an address. It never touches your wallet, never asks for a key or a seed phrase, and nobody at YOUNGLAB will ever ask you for one.

There is no card data because cards are not accepted, and no payment-provider script is loaded in your browser.

Refunds go back to the paying wallet, same token, same network, as the number of tokens received rather than their euro value on the day.

When something goes wrong.

Write with your order number and the transaction hash from your exchange. Late, short, or against an expired invoice — all of those get matched by hand. A nuisance, not a loss. A payment sent on the wrong network is the one case nobody can reverse, which is why it leads the list above.

Prefer not to?

Then don't. Bank transfer is the other rail: the account details and your reference appear as soon as you order and again in the email, and we pack the moment the money lands. Crypto is quicker; a transfer is ordinary. FAQ · Shipping & delivery
