# Offramp from External Address

> A payer deposits crypto on-chain to a Noxpay-generated address, and the equivalent BRL is sent to a payee via PIX.

<Note>
  This flow requires the **Infrastructure** product to be enabled on your account.
</Note>

## When to use this

Use Offramp Instant when a third party deposits crypto to fund the payment. Your Noxpay balance is not involved at any point. Common in peer-to-peer and B2B contexts where the sender holds crypto and the recipient needs BRL.

The payer sends crypto from their own wallet; the payee receives BRL via PIX. These can be the same person (a user cashing out their own wallet) or different people (a payer settling an invoice on behalf of a recipient).

## The full flow

```
Quote → Pre-KYC → Payee KYC → Crypto Deposit → Conversion → PIX Transfer → Success
```

<Steps>
  <Step title="Quote">
    A rate is calculated for the crypto → BRL conversion. The quote locks in the expected deposit amount — including a small unique suffix (see below), the BRL amount the payee will receive, the fees, and the rate. The rate is locked at this point.
  </Step>

  <Step title="Pre-KYC">
    The payee's CPF (individual) or CNPJ (business) is collected. This is the identity that will receive the PIX payment. The document is validated for format before proceeding.
  </Step>

  <Step title="Payee KYC">
    The payee's identity is verified against a Brazilian identity database and their PIX key is collected. The PIX key must belong to the verified document holder. Business payees (CNPJ) go through an additional business identity check.
  </Step>

  <Step title="Crypto deposit">
    A unique blockchain deposit address is generated for this transaction. The payer must send the **exact suffixed amount** shown to that address. Noxpay monitors the address and proceeds once the correct deposit is confirmed on-chain.
  </Step>

  <Step title="Conversion">
    The deposited crypto is converted to BRL at the locked quote rate.
  </Step>

  <Step title="PIX transfer">
    Noxpay sends the BRL amount via PIX to the payee's registered key.
  </Step>

  <Step title="Success">
    PIX delivery is confirmed. A webhook is sent including the `txHash` of the inbound crypto deposit.
  </Step>
</Steps>

## The deposit suffix

To prevent transaction misidentification — where two simultaneous deposits of the same amount could be attributed to the wrong session — Noxpay appends a small unique amount to the expected deposit.

For example, if the quoted amount is 100.000000 USDT, the deposit instruction shown to the payer might read **100.000017 USDT**. The payer must send that exact amount. Sending the round number (100.000000) will not match the transaction.

Make sure your UI communicates the exact suffixed amount clearly to the payer.

## Quote expiry on crypto deposit

If the crypto deposit does not arrive before the session expires, the transaction is set to `Expired`. A new transaction must be created. If a deposit arrives late (after expiry), Noxpay detects it and credits the received crypto to your Noxpay balance. Contact support if you need to resolve a late-arrival case.
