Script Type

Advanced

The category of Bitcoin locking script applied to an output, which determines how funds can be spent and what address format is used. Common script types are P2PKH (Legacy), P2SH (Script Hash), P2WPKH (native SegWit single-key), P2WSH (native SegWit script), and P2TR (Taproot). SSP multisig outputs use P2WSH; the script type affects fee cost, privacy, and hardware wallet compatibility.
