Trobkit

JavaScript / TypeScript SDK for the Trobium blockchain HTTP API.

| | | |---|---| | Chain | Trobium | | Package | trobkit | | Ticker | TROB | | Smallest unit | TROBI (1 TROB = 1_000_000 TROBI) | | Super Representatives | 21 (configured on-chain) | | Address prefix | 0x41 (Base58 addresses start with T) |

Trobkit is based on the TronWeb architecture and is protocol-compatible with Tron-like nodes, with Trobium branding, units, and error messages.

Installation

npm install trobkit

or

yarn add trobkit

Browser

cp node_modules/trobkit/dist/Trobkit.js ./js/trobkit.js

<script src="./js/trobkit.js"></script>

Creating an instance

import { Trobkit, utils as TrobkitUtils, Trob, TransactionBuilder, Contract, Event, Plugin } from 'trobkit';

const trobkit = new Trobkit({
    fullHost: 'https://your-trobium-fullhost.example',
    privateKey: 'your private key',
});

You can also set fullNode, solidityNode, and eventServer separately:

const trobkit = new Trobkit({
    fullNode: 'https://some-node.tld',
    solidityNode: 'https://some-other-node.tld',
    eventServer: 'https://some-event-server.tld',
    privateKey: 'your private key',
});

Legacy positional constructor is still supported:

const trobkit = new Trobkit(fullNode, solidityNode, eventServer, privateKey);

Units

Trobkit.toTrobi(1);      // "1000000"
Trobkit.fromTrobi(1000000); // "1"

Native transfers use sendTrob / transactionBuilder.sendTrob. The instance API for balances and signing lives on trobkit.trob.

Super Representatives

Trobium elects 21 Super Representatives. The SDK exposes SUPER_REPRESENTATIVE_COUNT for client use; witness lists are returned by the node (listSuperRepresentatives, etc.).

Compatibility

• Node.js v14 and above
• Browsers with more than 0.25% market share
• Frontend frameworks such as Angular, React, and Vue
• Chrome extensions

Built outputs:

• ESM / CJS under lib/
• UMD browser bundle: dist/Trobkit.js
• Node bundle: dist/Trobkit.node.js

Local testing

Point fullHost (or the test helper config) at your local Trobium node. By default the test suite expects a node on http://127.0.0.1:9090.

npm i
npm run build:all
npm run test
