@totemsdk/node

Core SDK wired for Node.js — server-side wallet operations.

Re-exports everything from @totemsdk/core and adds MinimaClient, MinimaWallet, and MinimaProvider for running a wallet on a server or in a bot/agent.

Install

npm install @totemsdk/node @noble/hashes

Requires Node.js ≥ 16. Dependencies: node-fetch, ws.

What's inside

| Export | What it does | |--------|-------------| | MinimaClient | WebSocket/HTTP client to a running Minima node | | MinimaWallet | Server-side wallet (sign, derive addresses, send transactions) | | MinimaProvider | Node.js ChainStateProvider implementation | | Everything from @totemsdk/core | Re-exported for convenience |

Usage

Connect to a node and sign

import { MinimaClient, MinimaWallet } from '@totemsdk/node';

const client = new MinimaClient({ nodeUrl: 'http://localhost:9005' });
const wallet = new MinimaWallet({ client });

// Initialize a fresh wallet (or pass a 24-word phrase to restore)
const seedPhrase = await wallet.initialize();
console.log('Seed phrase (store securely!):', seedPhrase);

// Derive an address
const account = await wallet.createAccount('main');
console.log('Address:', account.address);

// Sign arbitrary data
const sig = await wallet.signData(Buffer.from('hello world'), account.address);
console.log('Signature:', Buffer.from(sig).toString('hex'));

Use as a chain provider

import { MinimaClient, MinimaProvider } from '@totemsdk/node';

const client   = new MinimaClient({ nodeUrl: 'http://localhost:9005' });
const provider = new MinimaProvider(client);

const tip  = await provider.getChainTip();
const coins = await provider.getCoins({ address: 'Mx...' });

Send a transaction

const result = await wallet.send({
  to: 'MxDEF456...',
  amount: '10',
  tokenid: '0x00',
});
console.log('TxPoW ID:', result.txpowid);
