Installation

Core Package

The core SDK works in any JavaScript environment — Node.js, browsers, serverless, or scripts.

pnpm add @yo-protocol/core viem

npm install @yo-protocol/core viem

yarn add @yo-protocol/core viem

Dependency	Purpose
@yo-protocol/core	Client, vault reads, actions, API client, constants
viem	Low-level EVM interaction (contract calls, encoding, transports)

Zod included

@yo-protocol/core bundles zod internally for runtime validation of API responses. You do not need to install it separately.

React Package

For React apps using wagmi and TanStack Query:

pnpm add @yo-protocol/react @yo-protocol/core viem wagmi @tanstack/react-query

npm install @yo-protocol/react @yo-protocol/core viem wagmi @tanstack/react-query

yarn add @yo-protocol/react @yo-protocol/core viem wagmi @tanstack/react-query

Peer Dependencies

Package	Minimum version
react	18.0.0
react-dom	18.0.0
wagmi	2.0.0
viem	2.0.0
@tanstack/react-query	5.0.0

TypeScript

Both packages ship with full TypeScript declarations. TypeScript 5.0+ is recommended but not required — the SDK works fine in plain JavaScript.

Verify Installation

import { createYoClient } from '@yo-protocol/core'

const client = createYoClient({ chainId: 8453 })
const vaults = client.getVaults()

console.log(`Found ${vaults.length} vaults on Base`)
