• Unpacks a bigint back into a point on the Baby Jubjub elliptic curve, reversing the packing process. This involves interpreting the bigint as the y-coordinate and extracting the sign of the x-coordinate from the encoded format. The function then calculates the x-coordinate using the curve equation.


    • packedPoint: bigint

      The packed point as a bigint.

    Returns Point<bigint> | null

    The unpacked point as a pair of bigint values, or null if the point is invalid.
