An address is not a wallet, and a HD wallet is only locally relevant to your storage and is not reflected at all in the public ledger. Bitcoin works on a UTXO model where funds are paid to an output which can be spent by the owner of the.

‡ Ed25519 and BIP32 based on Khovratovich § Sr25519 planned. For the Curious: How Prefixes Work. The SS58 document states that: Polkadot has an address type of 00000000b, so 0 in decimal. Kusama (Polkadot Canary) has an address type of 00000010b, so 2 in decimal. Generic Substrate has 00101010b as address type, which is 42 in decimal bip39-lib.js works along with bip32-lib.js AND bitcoinjs-lib. BIP39 is strictly regarding the mnemonic phrase and HD seed. In order to derive child keys from an HD seed you'll also need to use BIP32. BUT... BIP32 has no concept of addresses either so ultimately you'll also need bitcoinjs-lib. In other words you need to use all three libraries to go from mnemonic to a usable address. Share. To restore the account from this JSON file, once again open the Polkadot{.js} browser plugin. Click on the + button at the top. This will open up a menu wih several choices - select Restore account from backup JSON file. The program then prompt you for the .json file which was download earlier and the password for that account 3. No, you cannot use ethers.js to generate a Bitcoin key pair. Most Bitcoin and Ethereum wallets use the same standard though ( BIP-32 and BIP-39 ), so you can simply use one of the other libraries that implement this functionality, like bitcoinjs-lib. There is an example using bitcoinjs-lib here: https://github

We are going to have a look at how to create your own Bitcoin wallets — Testnet and Mainnet, using a simple Node.js script. We can generate as many wallets (public/private key pairs) as you want instantly. We don't need to use any third-party blockchain providers for this, as the wallet generation part is done offline. In order to run the code given in this tutorial, we'll need Node.js.
