Installation

npm install @dogeuni-org/keyring

Quick Start

Basic Usage

import { DogeUniKeyring } from "@dogeuni-org/keyring";

// Create Keyring instance
const keyring = new DogeUniKeyring();

// Generate new mnemonic
const mnemonic = keyring.generateMnemonic();
console.log("Mnemonic:", mnemonic);

// Generate wallets for different networks
const bitcoinWallet = keyring.recoverWallet({
  mnemonic,
  network: "bitcoin",
  index: 0,
});

const dogecoinWallet = keyring.recoverWallet({
  mnemonic,
  network: "dogecoin",
  index: 0,
});

console.log("Bitcoin address:", bitcoinWallet.address);
console.log("Dogecoin address:", dogecoinWallet.address);

Network Configuration

import { MultiWalletManager } from "@dogeuni-org/keyring";
import { NetworkType } from "@dogeuni-org/keyring";

// Create wallet manager with specific networks enabled
const enabledNetworks: NetworkType[] = ["bitcoin", "dogecoin", "ethereum"];
const walletManager = new MultiWalletManager(
  undefined, // no initial wallets
  "my-password", // password
  enabledNetworks // only enable specified networks
);

// Check which networks are enabled
console.log("Enabled networks:", walletManager.getEnabledNetworks());

// Add a new network
walletManager.addEnabledNetwork("pepe");

// Remove a network
walletManager.removeEnabledNetwork("ethereum");

// Check if a network is enabled
console.log("Bitcoin enabled:", walletManager.isNetworkEnabled("bitcoin"));

// Reset to all supported networks
walletManager.resetNetworks();

Recover Wallet from Private Key

// Recover from private key
const wallet = keyring.recoverFromPrivateKey(
  "your-private-key-here",
  "bitcoin"
);

// Recover from WIF format
const wifWallet = keyring.recoverFromWIF("your-wif-private-key", "dogecoin");

Generate Multiple Addresses

// Generate 10 Bitcoin addresses
const wallets = keyring.generateMultipleWallets(mnemonic, "bitcoin", 10);

wallets.forEach((wallet, index) => {
  console.log(`Address ${index + 1}: ${wallet.address}`);
});

Ethereum-like Wallet Features

// Sign message
const message = "Hello from DogeUni!";
const signature = keyring.signMessage(
  message,
  wallet.privateKey,
  "ethereumfair"
);

// Verify signature
const recoveredAddress = keyring.verifyMessage(
  message,
  signature,
  "ethereumfair"
);

Encrypt Wallet

// Create encrypted wallet
const encryptedWallet = await keyring.createEncryptedWallet(
  wallet.privateKey,
  "your-password",
  "ethereumfair"
);

// Recover from encrypted wallet
const decryptedWallet = await keyring.recoverFromEncryptedJson(
  encryptedWallet,
  "your-password",
  "ethereumfair"
);

API Reference

DogeUniKeyring Class

Constructor

new DogeUniKeyring();

Methods

generateMnemonic(strength?: number): string

Generate a new mnemonic phrase

• strength: Entropy bits (128, 160, 192, 224, 256), defaults to 256

validateMnemonic(mnemonic: string): boolean

Validate if a mnemonic is valid

mnemonicToSeed(mnemonic: string, password?: string): string

Generate seed from mnemonic

generateWallet(options: KeyringOptions): WalletInfo

Generate a new wallet (automatically generates mnemonic)

recoverWallet(options: RecoveryOptions): WalletInfo

Recover wallet from mnemonic

recoverFromPrivateKey(privateKey: string, network: SupportedNetwork): WalletInfo

Recover wallet from private key

recoverFromWIF(wif: string, network: SupportedNetwork): WalletInfo

Recover wallet from WIF format private key

generateMultipleWallets(mnemonic: string, network: SupportedNetwork, count: number, derivationPath?: string): WalletInfo[]

Generate multiple wallet addresses

validateAddress(address: string, network: SupportedNetwork): boolean

Validate address format

signMessage(message: string, privateKey: string, network: SupportedNetwork): string

Sign message (only supports Ethereum-like networks)

verifyMessage(message: string, signature: string, network: SupportedNetwork): string

Verify message signature

createEncryptedWallet(privateKey: string, password: string, network: SupportedNetwork): Promise

Create encrypted wallet

recoverFromEncryptedJson(encryptedJson: string, password: string, network: SupportedNetwork): Promise

Recover wallet from encrypted JSON

Type Definitions

type SupportedNetwork =
  | "bitcoin"
  | "dogecoin"
  | "pepe"
  | "classzz"
  | "ethereumfair"
  | "dogeos";

interface WalletInfo {
  address: string;
  privateKey: string;
  publicKey: string;
  network: SupportedNetwork;
  derivationPath?: string;
}

interface KeyringOptions {
  network: SupportedNetwork;
  derivationPath?: string;
  password?: string;
}

interface RecoveryOptions {
  mnemonic: string;
  network: SupportedNetwork;
  derivationPath?: string;
  password?: string;
  index?: number;
}

Derivation Paths

The SDK uses standard BIP44 derivation paths:

• Bitcoin: m/44'/0'/0'/0/0
• Dogecoin: m/44'/3'/0'/0/0
• PEP/ClassZZ/EthereumFair/DogeOS: m/44'/60'/0'/0/0

Security Considerations

1. Private Key Security: Never hardcode private keys in client-side code
2. Mnemonic Backup: Securely backup mnemonics and never store them in the cloud
3. Password Strength: Use strong passwords to protect encrypted wallets
4. Environment Security: Generate and use wallets in secure environments

Bundle Optimization
