Crypto Payments

SecurQbit accepts cryptocurrency so you can subscribe without linking a card, bank, or personal payment method to your account. Crypto is the only payment method for anonymous accounts, and it's available to everyone else as a private alternative at checkout.

This guide walks through the whole flow: choosing a plan, applying an optional promo code, picking the correct token and network, and sending the exact amount to the payment address the right way.

What you can pay with

SecurQbit accepts two widely-used, US-dollar-pegged stablecoins — so the price you see is the price you pay, with no exchange-rate surprises.

Note: We don't accept volatile coins (such as BTC or ETH) directly for subscriptions. Stablecoins keep the amount due stable while your payment confirms on-chain. Which token you can use depends on the network — see the table below (for example, Base supports USDC only).

Supported networks

The same token (USDT or USDC) exists on several blockchains. The network you choose for your wallet must match the network you select at checkout — sending funds on the wrong network is the single most common way payments get lost.

Tip: All four networks are fast and low-fee. If you're paying with USDT, choose BNB Chain, Polygon, or Arbitrum — Base supports USDC only. If you're paying with USDC, any of the four works.

Step 1 — Choose a plan

Pick the plan you want in the app (SecurQbit → Account → Subscribe) or on securqbit.com. Pricing is the same full feature set on every plan, with bigger savings on longer terms — see Account & Billing for the current table.

Anonymous accounts: Free trials are not available on anonymous accounts. Choose a paid plan and pay with crypto to activate. See Anonymous Accounts for details.

Step 2 — Apply a promo code (optional)

If you have a discount or promo code:

1. On the plan or checkout screen, find the Promo code field.
2. Enter the code exactly as given and tap Apply.
3. The total updates immediately to reflect the discount.

Important: Apply your promo code before generating the payment address. The crypto amount shown is calculated from the discounted total, so a code added afterward won't change an address that's already been issued. If you applied a code late, cancel the unpaid invoice and start a new one.

Step 3 — Select Crypto and choose your token

1. At checkout, choose Crypto as the payment method.
2. Select the token you'll send — USDT or USDC.
3. Make sure it matches the token you actually hold in your wallet. USDT and USDC are not interchangeable; send the one you selected.

Note: Your token choice affects which networks are available. Base supports USDC only — if you select USDT, Base won't be offered, so pick BNB Chain, Polygon, or Arbitrum instead.

Step 4 — Choose the correct chain (network)

After selecting the token, choose the network you'll send it on — BNB Chain (BEP-20), Base, Polygon, or Arbitrum One.

The network must be supported for that token and available in your sending wallet. When in doubt, pick the network your wallet already holds the token on.

Critical: The network you pick here determines the address that's generated. Your wallet must send on the same network. USDC on Base cannot arrive at a Polygon address, and vice-versa — funds sent on a mismatched network are typically unrecoverable.

Step 5 — Send the exact amount

Once token and network are confirmed, SecurQbit displays a payment address, the exact amount to send, and (usually) a QR code and a countdown timer.

Send the payment the right way:

• Aim for the exact amount shown — to the last decimal. If you send a little more than the amount due, don't worry: the invoice is still marked paid and your order goes through (the extra isn't credited toward future renewals). If you send less, the invoice simply stays open — you can top it up by sending the remaining difference to the same address on the same network, and it's marked paid once the total received reaches the amount due.
• Use the displayed network only. Confirm your wallet is set to the same chain before you hit send.
• Send in a single transaction. Don't split the amount across multiple transfers to the same address.
• Pay before the timer expires. The address and quoted amount are valid only for that window. If it expires, generate a new invoice rather than sending to the old address.
• Account for wallet fees separately. Network (gas) fees are paid from your wallet balance on top of the amount — they don't come out of the amount sent to SecurQbit. Make sure you have a little extra for gas.
• Use a fresh address each time. Payment addresses are single-use. Don't reuse a previous invoice's address.

You can scan the QR code or copy the address manually — copying is safest. Always verify the first and last few characters of the pasted address match what's on screen.

Warning: Some clipboard-hijacking malware swaps copied crypto addresses. Always double-check the address after pasting it into your wallet.

Step 6 — Confirm you've sent the payment

After you broadcast the transfer from your wallet, return to the checkout screen and press "I've sent the payment" (the confirm button). This tells SecurQbit to start watching the blockchain for your transaction.

• Only press it after your wallet shows the transaction as sent.
• You don't need a transaction hash (TXID) or any reference number — every invoice has its own unique payment address, so SecurQbit matches your payment automatically.
• Pressing the button doesn't move any funds — your wallet has already done that. It just begins tracking.

Note: Don't close the invoice before confirming. If you press "I've sent" but haven't actually broadcast the transaction, the invoice simply stays pending until a payment arrives or the timer expires.

Step 7 — Wait for confirmation

After you send, the payment needs to confirm on the blockchain. Confirmation times vary by network (see the table above) and with network congestion.

• You don't need to keep the checkout page open — your subscription activates automatically once the payment confirms on-chain.
• You'll see your plan and renewal date update under Account → Subscription.
• There's nothing to submit — your payment is matched automatically to your invoice's unique address.

Note: Crypto subscriptions don't auto-renew. Near the end of your term you'll be prompted to pay again to extend. See renewals.

Troubleshooting

I sent the wrong amount. No payment is wasted — you can always fix it:

• Underpaid? The invoice stays open until the full amount is received. Just send the remaining difference to the same address on the same network while the invoice is still open, and it's marked paid as soon as the total received reaches the amount due. If the timer has already expired, contact support with your payment address.
• Overpaid (sent a bit more)? No problem — the invoice is still marked paid and your order activates automatically. Any small surplus isn't credited toward future renewals, so it's best to send the exact amount when you can.

I sent on the wrong network. Funds sent on a network that doesn't match the address are usually unrecoverable. Open a support request with your payment address; recovery isn't guaranteed.

The timer expired before my transaction confirmed. If you already broadcast the transaction to the correct address and network, it should still credit once it confirms — contact support with your payment address. If you hadn't sent yet, just start a new invoice.

My payment confirmed but my plan didn't activate. Allow a few extra minutes for slower networks. If it still hasn't updated, contact support through the Support page on securqbit.com with your payment address, the network, and the token you used.
