如何从 Solana 的助记词中获取正确的公共地址？

Question

I am trying to get proper public address for Solana wallet using solana-web3.js at my react-native test project

import { Keypair} from '@solana/web3.js';
import * as bip39 from 'bip39';
import * as bip32 from 'bip32';

const derivePath = "m/44'/501'/0'/0'";
const mnemonic = "...12 word phrase"

const seed: Buffer = yield bip39.mnemonicToSeed(mnemonic);
// also tried to slice seed.slice(0, 32);
const derivedSeed = bip32.fromSeed(seed).derivePath(derivePath).privateKey;
const keypair = Keypair.fromSeed(derivedSeed);
const publicKey = keypair.publicKey.toString();

I took derive path that is supposed to be for Phantom wallet (and could be chosen at Solflare wallet) But the problem is - I do not get the same public key as I get at these browser wallets.

So where am I possibly making mistake at code above?

UPDATE: When I use 'ed25519-hd-key' lib instead of 'bip32' to get derived seed problem disappears.

import * as ed25519 from 'ed25519-hd-key';

const derivedSeed = ed25519.derivePath(derivePath, seed.toString('hex')).key;

Answer 1

work variant for me:

import nacl from 'tweetnacl';
import * as bip39  from 'bip39';
import { derivePath } from 'ed25519-hd-key';

const web3 = require('@solana/web3.js')

const seed = await bip39.mnemonicToSeed(mnemonic);
const seedBuffer = Buffer.from(seed).toString('hex');
const path44Change = `m/44'/501'/0'/0'`;
const derivedSeed = derivePath(path44Change, seedBuffer).key;
keypair = new web3.Account(nacl.sign.keyPair.fromSeed(derivedSeed).secretKey);

Answer 2

您应该使用“m/501'/0'/0'”路径

Answer 3

This endpoint on the Blockchain API should help you.

It is called "Derive Public Key" and will derive and return a public key given a secret phrase, a derivation path, and a passphrase.

You can derive the appropriate public key with an API call.

Answer 4

I've try your same thing, and everything looks good but...I can't understand how solana-keygen generate that public address 'cuz if I backtest with this script on the mnemonic that solana-keygen give to me I can not get the same address... Some suggestion? If someone want to try this is what solana-keygen give me:

mnemonic = "title spell imitate observe kidney ready interest border inject quiz misery motor"

address = 'nsaayLiawKPiui9fWYCpRdYkdKeqj2fNn9u8LjauEkn'

I'm unable to understand which algorithm they use.

Please, do not fund this wallet.
