Class MultiKeySignature

constructor

• new MultiKeySignature(args): MultiKeySignature

• Signature for a K-of-N multi-sig transaction.

  Parameters

  • args: {
        bitmap: number[] | Uint8Array;
        signatures: (Signature | AnySignature)[];
    }

    • bitmap: number[] | Uint8Array

      4 bytes, at most 32 signatures are supported. If Nth bit value is 1, the Nth signature should be provided in signatures. Bits are read from left to right

    • signatures: (Signature | AnySignature)[]

      A list of signatures

  Returns MultiKeySignature

serialize

• serialize(serializer): void

• Parameters

  • serializer: Serializer

  Returns void

toUint8Array

• toUint8Array(): Uint8Array

• Get the raw signature bytes

  Returns Uint8Array

Static createBitmap

• createBitmap(args): Uint8Array

• Helper method to create a bitmap out of the specified bit positions

  Parameters

  • args: {
        bits: number[];
    }

    • bits: number[]

      The bitmap positions that should be set. A position starts at index 0. Valid position should range between 0 and 31.

  Returns Uint8Array

  bitmap that is 32bit long

  Example

  Here's an example of valid bits

  [0, 2, 31]
  Copy

  [0, 2, 31] means the 1st, 3rd and 32nd bits should be set in the bitmap. The result bitmap should be 0b1010000000000000000000000000001

Static deserialize

• deserialize(deserializer): MultiKeySignature

• Parameters

  • deserializer: Deserializer

  Returns MultiKeySignature
