Interface HDSignerAsync

Asynchronous counterpart of HDSigner for hardware wallets or remote signing services.

interface HDSignerAsync {
    fingerprint: Uint8Array;
    publicKey: PublicKey;
    derivePath(path: string): HDSignerAsync;
    sign(hash: MessageHash): Promise<Uint8Array<ArrayBufferLike>>;
}

Properties

`Readonly`fingerprint

fingerprint: Uint8Array

The first 4 bytes of the sha256-ripemd160 of the publicKey.

`Readonly`publicKey

publicKey: PublicKey

SEC1-encoded public key (33 or 65 bytes).

Methods

derivePath

derivePath(path: string): HDSignerAsync
Derives a child signer from a BIP-32 path.
Parameters
- path: string
  BIP-32 derivation path (e.g. m/44'/0'/0'/1/23).
Returns HDSignerAsync
- Defined in signer.ts:105

sign

sign(hash: MessageHash): Promise<Uint8Array<ArrayBufferLike>>
Produces a 64-byte compact ECDSA signature over hash.
Parameters
- hash: MessageHash
  32-byte message digest.
Returns Promise<Uint8Array<ArrayBufferLike>>
- Defined in signer.ts:110
