1️⃣Getting Started

The SDK is a monorepo of multiple packages that are dependencies of the core. These packages are:

• @veilnyx-sdk/account: For handling and using the shielded account of a user.

• @veilnyx-sdk/babyjubjub: Primitives for all the elliptic curve cryptography operations on the BabyJubJub curve.

• @veilnyx-sdk/transaction: For creation and handling of different kinds of transactions in the protocol.

• @veilnyx-sdk/zk-prover: For facilitating the generation of zkSNARK proof given transaction details.

• @veilnyx-sdk/services: Multiple services utilized in the protocol, like address resolver, Merkle tree builder, events fetcher, etc.

• @veilnyx-sdk/utils: Common utilities used across the different packages.

• @veilnyx-sdk/shared-types: TypeScript types shared across the packages.

• @veilnyx-sdk/core: The core that exposes the APIs for private transactions.

• @veilnyx-sdk/react(Coming Soon): React components and hooks for easy usage in React apps.

However, you don't need to install all of the packages. Just install @veilnyx-sdk/core In your project using your package manager,

# pnpm
pnpm add @veilnyx-sdk/core

# yarn
yarn add @veilnyx-sdk/core

# npm
npm i @veilnyx-sdk/core

Now you can simply import and use the SDK in your project,

import { CoreOptions, Core } from '@veilnyx-sdk/core';

const opts: CoreOptions = { ... }

const veilnyx = new Core(opts);

Before we move further into usage, let's clear a couple of concepts in the next sections so you can use it effectively!
