Status: Draft

==Abstract==
This document specifies raw() and addr() output script descriptors.
raw() encapsulates a raw script as a descriptor.
addr() encapsulates an address as a descriptor.

==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: raw() and addr().
===raw()===
The raw(HEX) 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 HEX.
===addr()===
The addr(ADDR) 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 ADDR.
==Test Vectors==
TBD
==Backwards Compatibility==
raw() and addr() 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 Implemntation==
raw() and addr descriptors have been implemented in Bitcoin Core since version 0.17.
