@orbinum/sdk

Official TypeScript SDK for Orbinum — a privacy-focused blockchain built on Substrate with an EVM compatibility layer.

Installation

npm install @orbinum/sdk
# or
pnpm add @orbinum/sdk

Requirements

• Node.js 18 or later
• A running Orbinum node (Substrate WebSocket endpoint)

Quick Start

import { OrbinumClient } from '@orbinum/sdk';

const client = await OrbinumClient.connect({
    substrateWs: 'ws://localhost:9944',
    evmRpc: 'http://localhost:9933', // optional
});

const info  = await client.substrate.getChainInfo();
const root  = await client.rpcV2.privacy.getMerkleRoot();
const block = await client.substrate.getBlock('best');
const isValidator = await client.rpcV2.chain.isValidator('5GrwvaEF...');

OrbinumClient exposes the following modules:

Property	Description
client.substrate	Substrate RPC — blocks, events, transactions
client.evm	EVM JSON-RPC client (null if evmRpc not set)
client.rpcV2	Orbinum rpc-v2 namespaces (chain_*, privacy_*)
client.rpcV2.chain	Chain-level queries (chain_isValidator, etc.)
client.shieldedPool	Shielded pool extrinsics
client.accountMapping	Alias, chain-link, and identity operations
client.precompiles	EVM precompile wrappers (null if evmRpc not set)

Each module can also be instantiated independently without OrbinumClient.
