Phantom Connect — Cursor Plugin

Give your agent a wallet. Swap, sign, and manage addresses across Phantom's supported chains — and tap into Phantom's docs for context. This plugin also includes skills, rules, and agents to help scaffold wallet-connected apps with the Phantom Connect SDK across React, React Native, and vanilla JS/TS.

Installation

1. Clone or copy this plugin into your Cursor plugins directory, or open the folder in Cursor.
2. Cursor will automatically detect the .cursor-plugin/plugin.json manifest.
3. The MCP servers (phantom-connect-sdk and phantom-mcp) will appear in your MCP settings.

What's Included

Skills

Skill	Description
setup-react-app	Scaffold a React app with @phantom/react-sdk, PhantomProvider, ConnectButton, and hooks
setup-browser-app	Scaffold a vanilla JS/TS app with @phantom/browser-sdk singleton pattern
setup-react-native-app	Scaffold a React Native (Expo) app with @phantom/react-native-sdk and required polyfills
send-sol-transaction	Build and send SOL transfers with proper signing and verification
sign-message	Implement message signing for Solana and EVM, including SIWS authentication
add-social-login	Configure Google/Apple social login with embedded wallet support
phantom-wallet-mcp	Execute wallet operations via the Phantom MCP — addresses, transfers, signing, swaps

Rules (Always Active)

Rule	What It Enforces
phantom-sdk-best-practices	Use signAndSendTransaction, proper provider setup, error handling, connection checks
solana-transaction-safety	Use LAMPORTS_PER_SOL, verify transactions, correct network selection, no key exposure
embedded-wallet-constraints	No signTransaction, spending limits, session duration, polyfill requirements

Agents

Agent	Purpose
Phantom Integration Specialist	SDK integration — scaffolds projects, writes correct code, validates against constraints, and looks up Phantom docs in real-time
Phantom Wallet Agent	Wallet operations — get addresses, transfer tokens, sign transactions, execute swaps, and sign messages via the phantom-mcp server

MCP Servers

Server	Transport	Description
phantom-connect-sdk	SSE	Phantom Connect SDK documentation at https://docs.phantom.com/mcp for real-time API reference
phantom-mcp	stdio	Wallet operations via @phantom/mcp-server — sign transactions, transfer tokens, buy tokens, sign messages

The phantom-mcp server requires a PHANTOM_APP_ID environment variable from Phantom Portal. Set it in your environment or Cursor MCP settings.

Usage

Once installed, ask the Cursor agent to:

• "Set up a React app with Phantom Connect"
• "Add social login with Google and Apple"
• "Send 0.1 SOL to an address"
• "Implement Sign-in with Solana"
• "Set up a React Native app with Phantom wallet"
• "Get my wallet addresses"
• "Transfer 0.5 SOL to [address]"
• "Sign this message with my wallet"

The agent will follow the plugin's skills and rules to generate correct, safe integration code.

Requirements

• Cursor editor
• A Phantom Portal account for appId registration: portal.phantom.com
