How money moves

From invoice to your balance, step by step

Every stage is written to an immutable ledger. No balance is ever edited by hand.

01
Merchant creates an invoice
Through a payment link or a single API call.
02
Address and QR generated
A dedicated deposit address per invoice on the chosen network.
03
Customer sends crypto
From any wallet or exchange. No account required.
04
Transfer crosses the network
We scan new blocks and match incoming transfers.
05
Confirmations accumulate
Nothing is final until the required confirmation depth.
06
Payment becomes confirmed
Status moves to paid and the journal is posted.
07
The 1% fee is separated
Platform fee is computed and shown apart from network fees.
08
Merchant balance updates
Funds move from pending to available.
09
Payout schedule activates
Immediate, daily, weekly, monthly or manual.

Underpayment

When exchanges deduct withdrawal fees

Customers frequently send from an exchange that deducts its fee, so less arrives than expected. You set the policy.

Strict

The invoice is not complete until the full amount arrives.

Smart tolerance

Accepts a shortfall up to the lower of $2 or 5% of the invoice.

Custom fixed

You set an absolute allowance within the platform cap.

Custom percentage

You set a percentage within the platform cap.

Accept actual

Settles on what actually arrived — only when you explicitly enable it.

On a shortfall the status becomes Partially paid, the exact remainder is shown, and monitoring continues on the same address. A second transfer is added to the first, never replacing it.

Payouts

Withdraw the way that suits you

Immediate payouts mean higher network fees. Aggregating is cheaper. You choose, and the cost is shown before you enable it.

Watch-only monitoring

Every balance derives from double-entry journals; corrections are compensating entries.

Signed webhooks

HMAC signatures with a timestamp header and replay protection.

Account protection

Two-factor authentication, recovery codes, session and device management.

Payout protection

Address allowlists, a cooldown after changes, and admin approval.
