BIP-0032 like derivation for ed25519 curve

Package Exports

  • near-hd-key

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (near-hd-key) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Usage

example:

const { derivePath, getMasterKeyFromSeed, getPublicKey } = require('ed25519-hd-key')
const hexSeed = 'fffcf9f6f3f0edeae7e4e1dedbd8d5d2cfccc9c6c3c0bdbab7b4b1aeaba8a5a29f9c999693908d8a8784817e7b7875726f6c696663605d5a5754514e4b484542';

const { key, chainCode } = getMasterKeyFromSeed(hexSeed);
console.log(key.toString('hex'))
// => 2b4be7f19ee27bbf30c667b642d5f4aa69fd169872f8fc3059c08ebae2eb19e7

const { key, chainCode} = derivePath("m/0'/2147483647'", hexSeed);

console.log(key.toString('hex'))
