## Overview

TIP-1022 virtual addresses let a service assign a distinct payment address to each customer while
forwarding supported payments to one registered master address. A virtual address encodes a
4-byte master ID and a 6-byte user tag in a normal 20-byte address.

Ox separates the local data operations from the network operations. Use
[`VirtualMaster`](/tempo/reference/VirtualMaster) to mine and verify a registration salt, and use
[`VirtualAddress`](/tempo/reference/VirtualAddress) to derive and parse virtual addresses. Registering
a master and resolving its current onchain record require a Tempo client or direct contract calls.

[See the Virtual Addresses specification](https://docs.tempo.xyz/protocol/tip20/virtual-addresses)
