🪙 DeLeeKat Wallet SDK

JavaScript SDK for interacting with DeLeeKat blockchain.

🚀 Installation

npm install deleekat-wallet-sdk

📖 Quick Start

Create a new wallet

const DeLeeKatWallet = require('deleekat-wallet-sdk');

const wallet = new DeLeeKatWallet({
  rpcUrl: 'https://rpc.deleekat.com',
  chainId: 7777
});

// Generate new wallet
const newWallet = wallet.generate();
console.log('Address:', newWallet.address);
console.log('Seed Phrase:', newWallet.mnemonic);

Import existing wallet

// From seed phrase
wallet.importFromMnemonic('your twelve word seed phrase here');

// From private key
wallet.importFromPrivateKey('0xYourPrivateKey');

Check balance

const balance = await wallet.getBalance();
console.log('Balance:', balance, 'DKT');

// Check any address
const otherBalance = await wallet.getBalance('0xOtherAddress');

Send DKT

const tx = await wallet.send('0xRecipientAddress', '10.5');
console.log('Transaction Hash:', tx.txHash);
console.log('Block Number:', tx.blockNumber);

Get transaction history

const history = await wallet.getTransactionHistory();
history.forEach(tx => {
  console.log(`${tx.type}: ${tx.value} DKT - ${tx.hash}`);
});

Network information

const info = await wallet.getNetworkInfo();
console.log('Chain ID:', info.chainId);
console.log('Current Block:', info.currentBlock);
console.log('Gas Price:', info.gasPrice);

Sign messages

const signature = await wallet.signMessage('Hello DeLeeKat!');
console.log('Signature:', signature);

// Verify signature
const signer = wallet.verifyMessage('Hello DeLeeKat!', signature);
console.log('Signer:', signer);

const wallet = new DeLeeKatWallet();
await wallet.importFromPrivateKey(process.env.MERCHANT_KEY);

// Check for payment
const balance = await wallet.getBalance();
console.log('Merchant balance:', balance, 'DKT');

🔒 Security Best Practices

1. Never expose private keys or seed phrases
2. Use environment variables for sensitive data
3. Implement rate limiting for production apps
4. Use HTTPS for RPC connections
5. Validate all addresses before sending
6. Store seed phrases encrypted in secure storage
