QUESTION
I'm using VueJS v3 and trying to generate and display a BIP39 mnemonic using the bip39 library. However I am getting an error in the browser console:

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:
QUESTION
I am trying to sign a message in go generated via hd wallet's private key using cosmos sdk. Below is the equivalent implementation in python which generates the signed message / signature as expected when submitted/verified is working properly but unable to get it working wtih Go implementation. Any inputs for equivalent golang version of the python implementation is much appreciated. Thank you.
Python version uses sha256 , ecdsa but when using the equivalent cyrpto/ecdsa doesn't return valid signature.

I am trying to generate hd wallet private keys , public keys and addresess using cosmos sdk. Below is the equivalent implementation in python which generates the keys , address as expected but when trying to generated in golang using cosmos sdk it won't generate same keys. Any inputs for equivalent golang version of the python implementation is much appreciated. Thank you.

ANSWER
Answered 2022-Feb-13 at 16:24The 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 ofhdwallet.path()shows. In the Go code, in contrast, the pathm/44'/118'/0'/0/0is used, as shown by the output ofpath.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:

Answered 2021-Sep-11 at 06:00Copy 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

I am able to send an EIP-1559 transaction through Rinkeby Testnet with Web3, the transaction completes without any trouble and I do get my Ether in my Metamask Rinkeby Account. The thing is that I am getting an Error: invalid remainder after the transaction completes and my program stops immediately.

QUESTION
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.
...ANSWER
Answered 2021-Aug-05 at 22:58There 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
QUESTION
The error I get from below is: 'The "data" argument must be of type string or an instance of Buffer, TypedArray, or DataView. Received an instance of Promise'

...ANSWER
Answered 2021-Apr-29 at 01:54Maybe your tutorial is out of date. In bip39's document, we have 2 kinds of mnemonicToSeed:
mnemonicToSeed: Async function which returns PromisemnemonicToSeedSync: Sync function which returns Buffer
As your example, we have 2 ways to solve it following 2 above functions.
