Unique SDK quick start

The SDK facilitates seamless integration of Unique Network's capabilities into the web3 application, bypassing the need for direct low-level API interaction. It enables you to effortlessly mint collections and tokens, manage account balances, and more.

All transactions require a fee so that you can use Opal tokens for test purposes. You can get them free in Telegram faucet botopen in new window.

Getting started

Installation

Install @unique-nft/sdk for Unique Network interaction and @unique-nft/sr25519 for account management.

npm install @unique-nft/sdk @unique-nft/sr25519

yarn add @unique-nft/sdk @unique-nft/sr25519

Import and initialize the SDK

To begin using the Unique SDK, you need to import the required modules, set the base URL for the API, and optionally configure the default signer account.

You can find the list of public endpoints in the reference section.

import { UniqueChain } from "@unique-nft/sdk";
import { Sr25519Account } from "@unique-nft/sr25519";


const mnemonic = "SET THE MNEMONIC SEED PHRASE FOR THE DEFAULT SIGNER HERE";
const account = Sr25519Account.fromUri(mnemonic);

// set "account" as a default signer
const sdk = UniqueChain({
  baseUrl: "https://rest.unique.network/v2/opal", 
  account,
});

Make some requests

...

const balanceQuery = await sdk.balance.get({address: account.address});
console.log("Account's total balance:", balanceQuery.total);

The Unique SDK currently supports the following modules:

collection: create, update, and manage NFT collections.
token: mint, transfer, and manage individual NFTs.
balance: manage and query account balances.
extrinsic: build, sign, submit any extrinsic.
options: configure SDK options.

Run your own HTTP proxy

Instead of using public SDK endpoints, you can easily run your own HTTP proxy. Create a docker-compose.yml with the following content, and run docker compose up.

version: "3.8"

services:
  substrate-proxy:
    image: uniquenetwork/substrate-proxy-http-proxy:master
    ports:
      - "3000:3000"
    environment:
      - PORT=3000
      - CHAIN=unique
      - MIN_LOG_LEVEL=info
      - EXTRINSIC_MORTAL_BLOCK_LENGTH=32
      - OPENAPI_SERVER_URL=http://localhost:3000
      - OPENAPI_SERVER_DESCRIPTION="Local development server"
      - EXTRINSICS_STORAGE_MAX_BLOCKS_COUNT=100
