Stablecoin payments.
Connected to your books.
Zetra monitors finalized NEAR payments and connects every confirmed transfer to the records in your books.
Example: a block explorer shows that 2,000 USDC moved. Zetra can connect a payment record to invoice INV-2041 and the books.
From a wallet address to a full set of books.
Start with the wallet you already use. Zetra reads its activity. Send invoices, or let your store send its orders, only when you want to.
Connect
Add a public wallet address. Zetra only watches it. It never asks for keys and can't move your money.
Collect
Send a payment request, connect your checkout, or keep accepting USDC at your existing address.
Match
Zetra uses the payment reference, known customer wallets, the amount and the timing to work out what each payment is for. Anything uncertain waits for you.
Book
Matched payments post to a double-entry ledger. Money nobody has claimed stays out of revenue until you say what it was.
Close
Review profit and loss, balance sheet and cash flow. Every figure links back to the entries and transactions behind it.
Know what you earned, spent and still owe.
Finalized NEAR receipts, invoices, bills and expenses land in the same ledger, with a source behind every posted entry.
Bills and expenses
Record what the business owes and what it has spent, approve the bill, then record the account used to pay it. Zetra records the accounting event; it does not move funds.
Double-entry books
Posted entries stay on record. A mistake is fixed with a reversing entry, so the history shows what changed and who changed it.
Reports your accountant can check
Profit and loss, balance sheet and cash flow come from posted entries. Export them as CSV or in QuickBooks and Xero import layouts.
Zetra currently accounts for USD stablecoins. Stripe Checkout is supported as a processor clearing source; bank feeds and tax filing are outside the product today.

Zetra doesn't guess with your money.
A partial payment, an overpayment, a payment in the wrong token or one nobody claims goes to a review list with the evidence and your options. Whatever you decide is recorded with your name and reason.
Partial and overpayments
$1,500 of $2,000 is tracked as partially paid with $500 remaining. $2,500 is paid, with the $500 difference held as customer credit.
Unknown payments
When nobody claims a payment, Zetra lists the invoices it could belong to and why each one fits. You assign it in two clicks, with a reason.
Nothing gets overwritten
Chain evidence can't be edited. A reversal or a resolution is a new entry, so you can always see what happened and when.
A payment record can move from detection to bookkeeping.
This diagram describes an example product flow. It is not a live transaction or a timing measurement.
- Payment details received. A payment record can be reviewed before it is applied to an invoice.
- Matching is reviewed. The example shows checks for the receiving wallet, asset and amount before an invoice is marked paid.
- Chain behavior is not implied. No transaction, confirmation or timing is represented by this illustration.

The API is versioned, with idempotency keys, cursor pagination and consistent errors. Webhooks are signed with HMAC, retried with backoff and can be replayed.
Non-custodial
Customers pay your wallet directly. Zetra reads public addresses only and never asks for keys, seed phrases or withdrawal rights.
One ledger
Invoices, bills, expenses and reports all post to the same journal. A correction adds an entry and leaves the original in place.
A source for every record
An onchain payment keeps its transaction evidence. A bill entered by hand keeps its document, the approval and the journal entry.
