Paying With USDT Crypto: A Beginner's Guide
PeptidesCanada accepts USDT cryptocurrency on the Ethereum (ERC-20) network only, and crypto orders receive a 5% discount. After you choose crypto at checkout, the Canadian-dollar total is converted to a USDT amount and the official wallet address is shown with your order. If you already hold USDT, it is a fast, low-friction way to pay — this guide walks through exactly how it works and how to do it safely.
Why crypto is offered, and the 5% discount
Crypto is offered as a convenient option for customers who already hold cryptocurrency and prefer to pay that way. To make it worthwhile, crypto orders receive a 5% discount off the order total — a direct saving compared with the other payment methods. For someone comfortable sending USDT, that discount is a real incentive.
The catalog accepts one specific form of crypto: USDT (the Tether stablecoin) on the Ethereum ERC-20 network. USDT is used because, as a stablecoin, its value tracks the US dollar, which keeps the amount predictable rather than swinging with the crypto market between checkout and payment.
What you need before you start
To pay this way you need a wallet that holds USDT on the Ethereum ERC-20 network, with enough balance to cover the order amount plus the network fee your wallet charges to send. Only USDT on the Ethereum ERC-20 network is accepted, so the single most useful thing to confirm before you begin is that your USDT is on that network — not on another chain.
This matters because USDT exists on several different networks, and they are not interchangeable when sending. Checking your wallet's network setting up front takes a moment and prevents the most common and costly mistake. If you are unsure, your wallet provider's documentation will show which network your USDT is held on.
Step by step: paying with USDT
The process is straightforward. First, choose crypto as your payment method at checkout — the 5% discount is applied automatically to the total. Next, the order is reserved and displays the converted USDT amount to send, the official Ethereum ERC-20 wallet address, and a QR code you can scan with your wallet.
Then, from your wallet, send exactly the USDT amount shown, on the Ethereum ERC-20 network, to the address provided. Finally, confirm your payment by submitting the transaction hash (explained below) so the order can be reviewed. That is the whole flow: choose crypto, send the shown amount on the right network, and confirm.
The critical network warning
This is the one point worth reading twice. Send only USDT on the Ethereum ERC-20 network, to the official address shown with your order. Sending any other asset, any other token, or USDT on any other network can result in a permanent loss that cannot be recovered by anyone.
Crypto transactions are irreversible, which is why a moment of checking beats any amount of regret. Before you hit send, confirm three things: the token is USDT, the network is Ethereum ERC-20, and the address matches the one shown with your order exactly. When those three line up, you are safe to send.
How the amount is calculated
You never have to calculate the crypto amount yourself. After you choose crypto, the Canadian-dollar order total — already reduced by the 5% discount — is converted to a USDT amount and locked in, then displayed with your order. You simply send the amount shown.
Because USDT is a stablecoin pegged to the US dollar, the converted figure stays stable rather than drifting with market volatility while you complete the transfer. Send the exact amount displayed; sending the precise figure shown is what lets the team match your payment to your order cleanly during review.
A quick pre-send checklist
Because crypto transfers cannot be reversed, it is worth running a short mental checklist before you press send. Confirm the token is USDT, not another coin. Confirm the network is Ethereum ERC-20, not another chain. Confirm the wallet address matches the one shown with your order, character for character — pasting and verifying beats typing. And confirm the amount matches the exact USDT figure displayed with your order.
Those four checks take seconds and prevent the handful of mistakes that actually cause problems with crypto payments. Once they line up — right token, right network, right address, right amount — you can send with confidence. Many wallets also let you scan the QR code shown with the order, which fills in the address automatically and removes the risk of a mistyped destination.
After you send: the transaction hash and review
Every crypto transaction produces a transaction hash — a long string of letters and numbers that uniquely identifies your payment on the blockchain. After sending, copy that hash from your wallet and submit it with your order to confirm payment. The hash is what lets the team locate and verify your transfer.
From there, the order stays reserved as pending while the payment is reviewed manually; nothing is marked paid automatically. Once the payment is confirmed, the order moves into processing and on to shipping. The how-to-order-securely and secure-payment-and-order-review guides linked below cover the review side of this in more depth.
