Parameters

Parameter	Type	Description
`components`	`PathComponent[]`	Array of path components (default: empty)
`sourceFingerprint`	`Buffer`	The source fingerprint (optional)
`depth`	`number`	The depth (optional)

PathComponent

The PathComponent class represents an individual component in a key path.

Parameters

Parameter	Type	Description
`index`	`number`	The component index (optional)
`hardened`	`boolean`	Whether it is hardened

Example


import { CryptoKeypath, PathComponent } from '@keystonehq/bc-ur-registry';
 
// BIP44: m/44'/60'/0'/0/0
const keypath = new CryptoKeypath([
  new PathComponent({ index: 44, hardened: true }),
  new PathComponent({ index: 60, hardened: true }),
  new PathComponent({ index: 0, hardened: true }),
  new PathComponent({ index: 0, hardened: false }),
  new PathComponent({ index: 0, hardened: false }),
]);
