Type declaration

  • Optional payment?: Payment

    The corresponding bitcoinjs-lib Payment for the provided expression, if applicable.

  • Optional expandedExpression?: string

    The expanded descriptor expression. See ExpansionMap for a detailed explanation.

  • Optional miniscript?: string

    The extracted miniscript from the expression, if any.

  • Optional expansionMap?: ExpansionMap

    A map of key expressions in the descriptor to their corresponding expanded keys. See ExpansionMap for a detailed explanation.

  • Optional isSegwit?: boolean

    A boolean indicating whether the descriptor uses SegWit.

  • Optional expandedMiniscript?: string

    The expanded miniscript, if any. It corresponds to the expandedExpression without the top-level script expression.

  • Optional redeemScript?: Buffer

    The redeem script for the descriptor, if applicable.

  • Optional witnessScript?: Buffer

    The witness script for the descriptor, if applicable.

  • isRanged: boolean
