Example Prompts

"Create a Next.js app with Phantom wallet connection"
"Build a token-gated page that requires 100 BONK to access"
"Make an NFT mint page with quantity selector and status handling"
"Add crypto checkout to my e-commerce site"
"Help me send a Solana transaction with the React SDK"
"Convert this to use the Browser SDK instead of React"
"Add a DFlow swap flow to my app"
"Help me trade into a prediction market position"
"Build a swap UI that lists wallet tokens on the FROM side"
"Add Proof KYC verification before prediction market buys"

SDK Choices

Platform	Package	Use Case
React Web	`@phantom/react-sdk`	Next.js, Vite, CRA
React Native	`@phantom/react-native-sdk`	Expo, bare RN
Vanilla JS	`@phantom/browser-sdk`	Vue, Angular, vanilla
Solana	`@solana/web3.js`	Transactions, balances

Prerequisites

All Phantom Connect integrations require:

Phantom Portal Account — phantom.com/portal/login
App ID — Get from Portal, required for Google/Apple social login
Allowlisted URLs — Add domains and redirect URLs in Portal

For DFlow integrations:

Dev endpoints work without an API key but are rate-limited
Apply for an API key before releasing to production
Prediction markets require geoblocking for restricted jurisdictions

The skill uses progressive disclosure. SKILL.md provides Claude with routing instructions and core knowledge. When a specific topic comes up, Claude reads the relevant file from references/ to get detailed implementation patterns. This keeps context usage efficient.
