Phantom Connect + DFlow Skill

Instructions

Step 1: Identify What the User Wants to Build

Determine the domain, then route to the right references.

Wallet connection and Solana interactions:

• Connecting a Phantom wallet (React, React Native, vanilla JS)
• Signing messages or transactions
• Token-gated access
• NFT minting
• Crypto payments
• Solana transfers (SOL or SPL tokens)

DFlow trading & market data:

• Spot token swaps (quote, sign, submit, confirm)
• Live prices, order-book depth, or priority-fee streaming

Many tasks combine both (for example, a swap UI needs wallet connection AND DFlow trading). Read all relevant references before writing code.

Step 2: Read the Relevant References

Phantom Connect SDKs (wallet connection, signing, auth):

• references/react-sdk.md: React hooks, components, theming, PhantomProvider
• references/react-native-sdk.md: Expo config, polyfills, deep links, mobile auth
• references/browser-sdk.md: BrowserSDK init, events, wallet discovery, vanilla JS

Solana patterns (transactions, gating, minting, payments):

• references/transactions.md: SOL/SPL transfers, signing, fee estimation
• references/token-gating.md: client-side and server-side token-gated access
• references/nft-minting.md: mint pages, Metaplex Core, compressed NFTs
• references/payments.md: SOL/USDC payments, checkout with backend verification

DFlow (swaps, streaming):

• references/dflow-crypto-trading.md: spot swaps via /order (atomic units, base58 mints, quote-without-wallet, priority/platform/sponsor fees)
• references/dflow-websockets.md: real-time quote, order-book, and priority-fee streaming (browser proxies through the backend)

Step 3: Ask the Right Questions

Before implementing, ask questions based on the domain:

For Phantom Connect tasks:

• Which platform? (React, React Native, vanilla JS)
• Do they need social login (Google/Apple) or extension only?

For DFlow tasks:

• Do you have a DFlow API key? (Yes: prod host with x-api-key. No: dev host, rate-limited. Prod key: pond.dflow.net/get-started/api-key.) It's one key for everything DFlow.
• Client environment? (web, mobile, backend, CLI) Browser apps keep the key on the backend and proxy DFlow HTTP and WebSocket through it.
• Platform fees? If yes, what bps and which builder-owned fee account (which must already exist)?

Step 4: Implement

Follow the patterns in the reference files. Key rules by domain:

Phantom Connect:

• All SDK details (provider setup, hooks, components, auth providers) are in the SDK reference files. Read them before writing Phantom integration code.

DFlow:

• Trades are synchronous: one /order call returns a signed-ready transaction that you sign, submit, and confirm.
• As a security best practice, keep the DFlow API key on the backend, not in browser code. Browser apps proxy DFlow HTTP (/order serves no CORS) and the WebSocket streams through their backend.
• Dev endpoints (dev-quote-api.dflow.net) work without a key but are rate-limited; production requires a key from pond.dflow.net/get-started/api-key. In production, quote and book stream access is granted per key.

Step 5: Handle Errors

Each reference file contains domain-specific error handling. Key cross-cutting concerns:

• User rejects a transaction or signature request
• Wallet not connected when a signed action is attempted
• DFlow API returns 429 (rate limited): retry with backoff or get a production API key
• route_not_found from DFlow: a likely cause is insufficient liquidity for the pair at that size; also check the mint addresses and that amount is in atomic units

Examples

Example 1: React wallet connection

User says: "Add Phantom wallet login to my Next.js app"

Actions:

1. Read references/react-sdk.md
2. Install @phantom/react-sdk
3. Wrap app in PhantomProvider with desired auth providers and appId
4. Use useModal hook for a connect button
5. Use useAccounts to display the connected wallet address

Result: Working wallet connection with social login and extension support

Example 2: Token-gated page

User says: "Build a page that only BONK holders can see"

Actions:

1. Read references/react-sdk.md and references/token-gating.md
2. Set up wallet connection
3. Query the BONK token balance for the connected wallet
4. Conditionally render content based on balance threshold
5. For production: add server-side signature verification

Result: Page that checks wallet token balance and gates content

Example 3: DFlow token swap

User says: "Add a swap feature using DFlow"

Actions:

1. Ask: API key? Client environment? Platform fees?
2. Read references/dflow-crypto-trading.md
3. Use the /order flow: request the order (proxy through the backend in a browser), deserialize the returned transaction, sign, submit, and confirm
4. In a browser, sign and send with the Phantom SDK (see references/transactions.md); server-side, sign with a keypair and submit through your RPC

Result: Working swap with DFlow routing

Example 4: Full swap page with wallet connection

User says: "Build a full swap page with wallet connect and DFlow"

Actions:

1. Ask: which platform? API key? Platform fees?
2. Read the relevant SDK reference AND references/dflow-crypto-trading.md
3. Set up wallet connection with the Phantom SDK
4. Build the swap form; proxy /order through the backend so the key stays server-side
5. Sign and send with the Phantom SDK, then confirm

Result: End-to-end swap page combining Phantom wallet and DFlow trading

Example 5: Live order book

User says: "Show a live order book for a token pair"

Actions:

1. Read references/dflow-websockets.md
2. Stand up a backend relay that holds the key, opens /book-stream with the x-api-key header, and relays frames to the browser
3. Subscribe with { op: "subscribe", base_mint, quote_mint }; render the batched per-slot updates[]
4. Reconnect and re-subscribe on drop

Result: Live streaming order book, key kept server-side
