==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. ==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: 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 Implementation== raw() and addr() descriptors have been implemented in Bitcoin Core since version 0.17.
