# init(_:) Creates a script pubkey from serialized script data. ``` init(_ data: Data) ``` ## Parameters `data` Raw script bytes. Empty input traps via `preconditionFailure`. ## Discussion Accepts the raw byte layout used in a transaction output’s scriptPubkey field — opcodes and pushed data as stored on disk, not an ASM-decoded string. No structural validation happens here; an empty or malformed script parses but will fail verification.
