Frequently Asked Questions

Enter your email on the sign-in page and we'll send you a magic link — click it and you're in. No password, and no wallet needed just to create your account.

Yes, on both sides — you need a Solana wallet to receive payments, and your customers need one to pay their invoice. Phantom, Solflare, and Backpack all work. You only need a wallet address to get paid; your customers use whichever supported wallet they already have.

To send invoices, no — signing in and creating invoices costs nothing, and you never need to hold crypto yourself to send one. Your customers do: paying an invoice takes a Solana wallet holding USDC plus a small amount of SOL for the network fee. See "What does my customer need to pay an invoice?" under Payments.

Go to Settings from the sidebar, then fill in your business information including your full name, email address, business name, and mobile number. This information appears on your invoices and helps customers identify your business.

Any amount up to 10,000 USDC per invoice (the platform fee is taken from that amount, not added on top). Larger jobs can be split across invoices.

TXN uses email magic links — no password to remember, no wallet signature required. Enter your email, click the link we send you, and you're signed in. Links expire after a short time for security; just request a new one if yours has expired.

No — they're separate. Your account is your email. Your receiving wallet is just the Solana address where invoice payments land, set once in Settings. You never connect a wallet extension or sign a message to use TXN as a merchant.

Yes. Adding a receiving wallet only stores its public address — a string of text, not a live connection to your wallet. TXN never has access to your private keys or seed phrase, and can't move funds out of your wallet under any circumstance.

Yes, any time from Settings. Changing it only affects invoices you send afterward — invoices already sent keep the wallet address that was set when they were sent, so in-flight payments always go where the payer expects.

Your TXN account itself is unaffected — it's tied to your email, not your wallet. If you lose access to your Solana wallet, recover it the normal way (your seed phrase, with your wallet provider), then update your receiving wallet address in TXN Settings once you have a working wallet again.

Click 'Create Invoice' from the Dashboard or Invoices page. Fill in the customer details, add line items with descriptions, quantities, and prices, set the due date, and click 'Save as Draft' or 'Create and Send Now'. The invoice will be sent to your customer's email with a secure payment link.

We offer several payment term options: Due on Receipt, Due in 7 days, Due in 30 days, Due in 60 Days, and Due in 90 days. Choose the option that works best for your business relationship.

Yes, you can edit invoices that are in Draft, Pending, or Overdue status. However, once an invoice is marked as Paid, it becomes a permanent financial record and cannot be edited, resent, or deleted.

Go to the Invoices page, find the invoice you want to resend, click the three-dot menu on the right, and select 'Resend Invoice Email'. Note that paid invoices cannot be resent.

Draft: Invoice is saved but not sent. Pending: Invoice has been emailed to the customer. Paid: Payment has been received and confirmed on-chain. Overdue: The due date has passed without payment. Cancelled: Invoice has been cancelled (soft-deleted).

Draft invoices can be permanently deleted. Sent, viewed, and overdue invoices are soft-deleted (cancelled) to maintain an audit trail. Paid invoices cannot be deleted - they are permanent financial records.

Four steps, once: (1) install a supported Solana wallet such as Phantom, Solflare or Backpack; (2) add a small amount of SOL to it for network fees — a few dollars' worth covers hundreds of payments; (3) get USDC on the Solana network, either by buying USDC on an exchange and withdrawing it to the wallet on Solana, or by swapping inside the wallet; (4) open the invoice link and approve the payment in the wallet. After that, paying an invoice is one tap.

Customers receive an email with a secure payment link. On mobile, scanning the QR code opens their Solana wallet directly via deep link for seamless payment. On desktop, they can connect any supported Solana wallet and pay with one click. All payments are made in USDC stablecoin.

USDC (USD Coin) is a stablecoin pegged 1:1 to the US Dollar. This means 1 USDC always equals $1 USD. It provides the stability of traditional currency with the speed and low fees of blockchain transactions on Solana.

Payments on Solana typically confirm within seconds. Once confirmed on-chain, the funds are already in your wallet and the invoice status updates to Paid automatically.

We charge a simple 1% platform fee, capped at $10 USDC per payment, taken from the invoice amount. Separately, the payer covers the Solana network fee in SOL — a fraction of a cent per payment; the first payment to a new recipient can include a one-time account deposit of about 0.002 SOL. This is significantly lower than traditional payment processors that charge 2.9% + $0.30.

Payment failures are rare on Solana but can happen when the wallet lacks enough USDC, has no SOL for the network fee, or the network is congested. The customer will see an error message and can retry the payment. The invoice status will remain unchanged until successfully paid.

Currently, we only support USDC payments via a Solana wallet (Phantom, Solflare, Backpack, and others all work). This allows us to offer lower fees, and payments typically confirm within seconds. Credit card support may be added in future updates.

When customers view an invoice on mobile, they can scan the QR code which opens their Solana wallet directly via a deep link. The payment details are pre-filled, so they just need to approve the transaction. This provides a seamless mobile payment experience.

No, paying an invoice does not create an account for the customer. They remain only in the contact list of a user that sent them an invoice or added them as a customer.

Go to the Customers page and click 'Add Customer'. Enter their name, email, mobile number (optional), and wallet address (optional). You can also add customers directly while creating an invoice.

Currently, customers need to be added manually. We're working on a bulk import feature. For now, you can add customers one at a time or create them while generating invoices.

Yes, you can delete customers from the Customers page. However, this won't delete invoices associated with that customer. Historical invoice data is preserved for your financial records.

Customer wallet addresses are not automatically captured when they pay an invoice. This is intentional for several reasons: wallet addresses are personal identifiers that require consent to store, you may have manually entered a different wallet address, and customers may use different wallets for different payments. You can always add or update a customer’s wallet address manually.

To convert your USDC to regular currency, transfer your USDC from your Solana wallet to a cryptocurrency exchange like Coinbase, Binance, or Kraken. From there, you can sell USDC for your local currency and withdraw to your bank account. Each exchange has its own withdrawal process and fees.

TXN doesn't charge fees for withdrawing USDC from your wallet. However, the exchange you use (Coinbase, Binance, Kraken, etc.) may charge trading and withdrawal fees. These vary by exchange and withdrawal method. Solana network transfer fees are minimal (less than $0.01).
