# TrustConnect SDK

The free, open-source wallet connection SDK for every chain, built by Trust Wallet. TrustConnect is a [CAIP](https://chainagnostic.org/)-compliant, multi-chain SDK that connects your dApp to Trust Wallet and other wallets across EVM, Solana, and Bitcoin — with a React hooks API and fully customizable UI.

## Install

Install the core React package:

```bash
pnpm add @trustwallet/connect-react
```

Then add the network-specific packages for the chains you need:

```bash
# EVM chains (Ethereum, Polygon, etc.)
pnpm add @trustwallet/connect-eip155-react

# Solana
pnpm add @trustwallet/connect-solana-react

# Bitcoin
pnpm add @trustwallet/connect-bip122-react
```

For WalletConnect support (mobile and QR code connections):

```bash
pnpm add @trustwallet/connect-walletconnect
```

EIP-155 peer dependencies (if not already installed):

```bash
pnpm add @tanstack/react-query viem
```
