HD Wallets with Nethereum

Two implementations available:

Full HD Wallet (NBitcoin-based)

NuGet: Nethereum.HDWallet

bash
dotnet add package Nethereum.HDWallet
Generate New Wallet
csharp
using Nethereum.HdWallet;
using NBitcoin;
 
var wallet = new Wallet(Wordlist.English, WordCount.Twelve);
var mnemonic = string.Join(" ", wallet.Words);
Restore from Mnemonic
csharp
var wallet = new Wallet("rapid squeeze excess salute ...", seedPassword: null);
var account = wallet.GetAccount(0, chainId: 1);
var web3 = new Web3(account, "https://your-rpc-url");
Derivation Paths
csharp
// Default: m/44'/60'/0'/0/x (MetaMask, TREZOR, MEW)
var wallet = new Wallet(words, null, Wallet.DEFAULT_PATH);
 
// Ledger/Electrum: m/44'/60'/0'/x
var wallet = new Wallet(words, null, Wallet.ELECTRUM_LEDGER_PATH);
Key Methods
csharp
var addresses = wallet.GetAddresses(10);     // First 10 addresses
var privateKey = wallet.GetPrivateKey(0);     // Private key bytes
var ethKey = wallet.GetEthereumKey(0);        // EthECKey for signing
var account = wallet.GetAccount(0, chainId: 1); // Account for Web3
Watch-Only (Public Wallet)
csharp
var xPub = wallet.GetMasterExtPubKey();
var publicWallet = new PublicWallet(xPub);
var addresses = publicWallet.GetAddresses(10);

Light HD Wallet (Zero Dependencies)

Included in Nethereum.Accounts — no extra package needed. Uses only System.Security.Cryptography. Modern .NET only (net6.0+).

csharp
using Nethereum.Accounts.Bip32;
 
// Generate mnemonic
var mnemonic = Bip39.GenerateMnemonic(12);
 
// Create wallet
var wallet = new MinimalHDWallet(mnemonic);
 
// Derive keys (m/44'/60'/0'/0/{index})
var key = wallet.GetEthereumKey(0);
var address = wallet.GetEthereumAddress(0);
 
// Custom path
var key = wallet.GetKeyFromPath("m/44'/60'/0'/0/5");
