At a glance

Builds Solana wallet-connected apps with Phantom Connect SDKs for React, React Native and vanilla JS, plus DFlow spot swaps and market-data streaming.

  • Works in 5 steps: Identify What the User Wants to Build → Read the Relevant References → Ask the Right Questions → …
  • Connecting a Phantom wallet in a React, React Native or vanilla JS app
  • SKILL.md covers Instructions, Examples and Resources
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

The skill routes each task to reference files by domain. Phantom references cover the React SDK, the React Native SDK and the browser SDK, and Solana pattern references cover transfers and signing, token gating, NFT minting and SOL or USDC payments with backend verification. DFlow references cover spot swaps through its order endpoint (quote, sign, submit, confirm) and live quote, order-book and priority-fee streaming. Many tasks combine both, so all relevant references are read before any code is written.

Before implementing, the agent asks which platform you target, whether you want social login or the extension only, whether you have a DFlow API key (a production host with an `x-api-key` header, or a rate-limited development host), where the client runs, and whether platform fees apply. Browser apps keep the key on the backend and proxy DFlow HTTP and WebSocket calls through it. It is not for Ethereum or EVM wallets or for DEX routing outside DFlow. The excerpt is truncated.

When your agent uses it

  • Connecting a Phantom wallet in a React, React Native or vanilla JS app
  • Signing messages or transactions on Solana
  • Building a token-gated page or an NFT mint page
  • Adding DFlow token swaps or live market-data streaming

Example prompts

  • “Add a Connect Phantom button to my React app and show the connected address.”
  • “Build a token-gated page that checks whether the visitor's wallet holds a given SPL token.”
  • “Add a SOL to USDC swap screen using DFlow, with the API key kept on the backend.”

Requirements

  • A Phantom wallet or Phantom Connect app setup
  • A DFlow API key for production use (a rate-limited dev host works without one)

Workflow steps

5 steps, taken from the step headings in SKILL.md.

  1. Identify What the User Wants to Build
  2. Read the Relevant References
  3. Ask the Right Questions
  4. Implement
  5. Handle Errors

What it can do on your machine

Read from SKILL.md and the folder at commit fa89195. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Phantom Connect and DFlow loads about 1.8k tokens when it runs, and up to ~15k if it reads all its reference files. Until then it costs about 135 tokens; SKILL.md has 846 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~135
When it runs · the whole SKILL.md, loaded when a task matches
~1.8k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~15k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

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
