Functions

Const compressPublicKey

  • compressPublicKey(publicKey: Uint8Array): Uint8Array

  • Compress a public key. This function takes both compressed and uncompressed public keys, and always returns the compressed variant.

    Parameters

    • publicKey: Uint8Array

    Returns Uint8Array

Const decodeBase58

  • decodeBase58(encoded: string): Uint8Array

  • Decode a Base58 string to a Buffer. Throws an error if the checksum is invalid.

    Parameters

    • encoded: string

    Returns Uint8Array

Const decompressPublicKey

  • decompressPublicKey(publicKey: Uint8Array): Uint8Array

  • Decompress a public key. This function takes both compressed and uncompressed public keys, and always returns the decompressed variant.

    Parameters

    • publicKey: Uint8Array

    Returns Uint8Array

Const encodeBase58

  • encodeBase58(data: Uint8Array): string

  • Encode a Buffer as Base58 string with a checksum applied.

    Parameters

    • data: Uint8Array

    Returns string

Const getAddress

  • getAddress(publicKey: Uint8Array): string

  • Get the Ethereum address for a public key.

    Parameters

    • publicKey: Uint8Array
