Here's a live demo for a working solution:

Got to say though, I didn't have an easy time trying out that module. I think its designed to be run server-side, and not in the browser like this. There may also be some security considerations to take account for if you're using this in production, but that's a separate issue.

Here's a working Vue component I built to demonstrate usage:

The results of both codes differ because of two issues:

In the Go Code, the private key is derived incorrectly:

In the Python code, the path m/44'/118'/0'/0/0' is used, as the output of hdwallet.path() shows. In the Go code, in contrast, the path m/44'/118'/0'/0/0 is used, as shown by the output of path.String().

To use the path of the Python code in the Go code, the path can be e.g. specified directly. For this the line:

One way to hint to the compiler is to add an else clause, that way the compiler is sure the else branch will only execute when WORDLIST[language]!=null.

Copy the contents of my-keypair.json and hit import wallet in phantom and paste this private key there. Then your account should be showing up.

Also check on which net you're on. Could be devnet/ testnet/ or localnet. The balances in each network would be different.

For getting SOL token on devnet you can use the airdrop function from the cli

I'm trying to use a wallet seed on the backend, using nodejs, to connect in blokchain. The Keypair module from "@solana/web3.js" library has a fromSeed method, that I use with input from another method, from the bip39 library, that converts my mnemonic to a seed. This my code

Keypair.fromSeed() takes a Unit8Array check

buffer.toJSON().data this returns a 64 length array, So this contains both the public key and private key respectively. Check this

How to generate a private key for Ethereum from the mnemonic?

Asked 2021-Aug-06 at 07:42

I generated a new mnemonic using bip39 package: bip39.generateMnemonic(). There is the next step where I need to convert it into 64 characters of hex-string. I can make it using SHA-256 but it looks little weirdly because of I will apply ECDSA-256 and KECCAK-256 to generate a public key.

Is it right way to generate a private key from the mnemonic using SHA-256? Or should I use another hash-function?

P.S. I am a noobie in Ethereum system.

There is a library called tweetNacl that have several functionalities including generating a keyPair from a seed. It is also available in dart as pineNacl here.

I have not tried the dart one myself but you should be able to generate a keyPair from a seed. You can also see conversion of mnemonic into a 32-byte seed here

After scrolling through some really confusing documentation of its dart implementation. You should be able to generate a keyPair from a seed with something like a function like this

Maybe your tutorial is out of date. In bip39's document, we have 2 kinds of mnemonicToSeed:

mnemonicToSeed: Async function which returns Promise
mnemonicToSeedSync: Sync function which returns Buffer

As your example, we have 2 ways to solve it following 2 above functions.
