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:

  • Spot token swaps (imperative or declarative)

  • Prediction market discovery, trading, and redemption

  • Proof KYC identity verification

Many tasks combine both (e.g., 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 trading (swaps, prediction markets, KYC):

  • references/dflow-crypto-trading.md — spot token swaps, imperative vs declarative trades, slippage, priority fees, platform fees

  • references/dflow-prediction-markets.md — market discovery, trading, redemption, maintenance windows, fee models

  • references/dflow-websockets.md — real-time price, trade, and orderbook streaming via WebSocket

  • references/dflow-proof.md — Proof KYC verification (required for prediction market trades, usable for any gated feature)

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 spot trades:

  • Imperative or declarative? If unsure, suggest starting with imperative.

  • Dev or production endpoints? If production, remind them to apply for an API key at pond.dflow.net/build/api-key.

  • Platform fees? If yes, what bps and what fee account?

  • Client environment? (web, mobile, backend, CLI)

For DFlow prediction markets:

  • Settlement mint? (USDC or CASH — these are the only two)

  • Dev or production endpoints? If production, remind them to apply for an API key at pond.dflow.net/build/api-key.

  • Platform fees? If yes, use platformFeeScale for dynamic fees.

  • Client environment? (web, mobile, backend, CLI)

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 Trading:

  • Dev endpoints (dev-quote-api.dflow.net , dev-prediction-markets-api.dflow.net , wss://dev-prediction-markets-api.dflow.net/api/v1/ws ) work without an API key but are rate-limited. Production requires a key from pond.dflow.net/build/api-key.

  • Prediction market trades require Proof KYC before buying or selling outcome tokens. Browsing and discovery do not require KYC.

  • Prediction markets also require geoblocking for restricted jurisdictions.

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 — check amount units (must be atomic), check liquidity, check mint addresses

Examples

Example 1: React wallet connection

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

Actions:

  • Read references/react-sdk.md

  • Install @phantom/react-sdk

  • Wrap app in PhantomProvider with desired auth providers and appId

  • Use useModal hook for a connect button

  • 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:

  • Read references/react-sdk.md and references/token-gating.md

  • Set up wallet connection

  • Query the BONK token balance for the connected wallet

  • Conditionally render content based on balance threshold

  • 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:

  • Ask: imperative or declarative? Platform fees? Client environment?

  • Read references/dflow-crypto-trading.md

  • If unsure on trade type, suggest imperative /order flow (simpler, synchronous)

  • Connect wallet with Phantom, sign and submit transaction to Solana RPC

Result: Working swap UI with DFlow routing

Example 4: Prediction market trade

User says: "Let users buy YES/NO positions on prediction markets"

Actions:

  • Ask: settlement mint (USDC or CASH)? Platform fees? Client environment?

  • Read references/dflow-prediction-markets.md and references/dflow-proof.md

  • Build market discovery UI from Metadata API

  • Gate trades behind Proof KYC verification

  • Use /order endpoint to trade settlement mint into outcome tokens

Result: Prediction market UI with KYC-gated trading

Example 5: Swap UI with wallet connection

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

Actions:

  • Ask: which platform? Imperative or declarative swap? Platform fees?

  • Read the relevant SDK reference AND references/dflow-crypto-trading.md

  • Set up wallet connection with Phantom

  • Build swap form, proxy /order calls through backend

  • Sign transaction with connected wallet, submit to RPC

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