BIP: 385
Layer: Applications
Title: raw() and addr() Output Script Descriptors
Author: Pieter Wuille <pieter@wuille.net>

Comments-Summary: No comments yet.
Comments-URI: https://github.com/bitcoin/bips/wiki/Comments:BIP-0385
Status: Draft
Type: Informational
Created: 2021-06-27
License: BSD-2-Clause

==Abstract==
This document specifies <tt>raw()</tt> and <tt>addr()</tt> output script descriptors.
<tt>raw()</tt> encapsulates a raw script as a descriptor.
<tt>addr()</tt> encapsulates an address as a descriptor.
==Copyright==
This BIP is licensed under the BSD 2-clause license.
==Motivation==
In order to make descriptors maximally compatible with scripts in use today, it is useful to be able to wrap any arbitrary output script or an address into a descriptor.
==Specification==
Two new script expressions are defined: <tt>raw()</tt> and <tt>addr()</tt>.
===<tt>raw()</tt>===
The <tt>raw(HEX)</tt> expression can only be used as a top level descriptor.
As the argument, it takes a hex string representing a Bitcoin script.
The output script produced by this descriptor is the script represented by <tt>HEX</tt>.
===<tt>addr()</tt>===
The <tt>addr(ADDR)</tt> expression can only be used as a top level descriptor.
It takes an address as its single argument.
The output script produced by this descriptor is the output script produced by the address <tt>ADDR</tt>.
==Test Vectors==
TBD
==Backwards Compatibility==
<tt>raw()</tt> and <tt>addr()</tt> descriptors use the format and general operation specified in [[bip-0380.mediawiki|380]].
As this is a wholly new descriptor, it is not compatible with any implementation.
The reuse of existing Bitcoin addresses allows for this to be more easily implemented.
==Reference Implementation==
<tt>raw()</tt> and <tt>addr()</tt> descriptors have been implemented in Bitcoin Core since version 0.17.
