# Marketplace

ZB-1 includes an application-layer marketplace model based on signed ownership authorization and confirmed Zcash payment transactions.

## SALE

A seller can create an authorized sale order for a token they currently own.

The final public v1 sale schema must bind at least:

* Protocol version
* Genesis identifier
* Token ID
* Seller ownership state
* Asking price
* Order identifier / replay protection
* Seller authorization signature

## BUY

A valid ZB-1 BUY must satisfy both ownership and payment rules.

For an official marketplace sale:

```
97% → seller
3%  → ZB-1 treasury
```

The transaction must satisfy the exact price and protocol-fee conditions defined by the signed sale order.

## Marketplace fee

The v1 marketplace protocol fee is:

```
300 basis points = 3%
```

## Enforcement boundary

{% hint style="info" %}
The 3% fee is mandatory for a transaction to be accepted as a valid **ZB-1 BUY**.

It is not enforced by Zcash consensus against every possible direct transfer or external payment arrangement.
