Phantom Connect Agent Skill

> Build wallet-connected applications with the Phantom Connect SDK for Solana. Use when integrating Phantom wallets into React, React Native, or vanilla JS/TS apps — including wallet connection, social login (Google/Apple), transaction signing, message signing, token-gated access, crypto payments, and NFT minting. Covers @phantom/react-sdk, @phantom/react-native-sdk, and @phantom/browser-sdk.

Phantom Connect SDK

Build wallet-connected Solana applications with the Phantom Connect SDK ecosystem.

SDK Selection

| Platform | SDK | Package |

|----------|-----|---------|

| React web apps | React SDK | @phantom/react-sdk |

| React Native / Expo | React Native SDK | @phantom/react-native-sdk |

| Vanilla JS / Vue / Angular | Browser SDK | @phantom/browser-sdk |

Prerequisites

Phantom Portal Account — Register at phantom.com/portal
App ID — Get from Portal → App → Set Up
Allowlisted URLs — Add domains and redirect URLs in Portal

Auth Providers

| Provider | Description | Requires appId |

|----------|-------------|----------------|

| "injected" | Phantom browser extension | No |

| "google" | Google OAuth (embedded wallet) | Yes |

| "apple" | Apple ID (embedded wallet) | Yes |

Critical Rules

Always use signAndSendTransaction — signTransaction and signAllTransactions are NOT supported for embedded wallets
Always use LAMPORTS_PER_SOL from @solana/web3.js for amount conversion — never hardcode 1000000000
Wrap all async SDK calls in try-catch — users can reject prompts at any time
Check isConnected before signing — verify wallet connection before any operation
React Native: react-native-get-random-values must be the FIRST import — before any other imports
BrowserSDK must be a singleton — create one instance per app, never multiple
Import AddressType from @phantom/browser-sdk only
Use devnet for testing, mainnet-beta for production — never test against mainnet with real funds
Never expose private keys — Phantom handles all signing internally

10. Embedded wallet spending limit: $1,000 USD per day per app per user

11. Social login sessions persist 7 days from last auth event — handle expiration gracefully

Quick Start

React SDK

import { PhantomProvider, useModal, usePhantom, darkTheme } from "@phantom/react-sdk";
import { AddressType } from "@phantom/browser-sdk";

function App() {
  return (
    <PhantomProvider
      config={{
        providers: ["google", "apple", "injected"],
        appId: "your-app-id",
        addressTypes: [AddressType.solana],
        authOptions: { redirectUrl: "https://yourapp.com/callback" },
      }}
      theme={darkTheme}
    >
      <YourApp />
    </PhantomProvider>
  );
}

React Native SDK

// CRITICAL: Must be first import
import "react-native-get-random-values";
import { PhantomProvider, AddressType, darkTheme } from "@phantom/react-native-sdk";

// Requires app.json: { "expo": { "scheme": "myapp", "plugins": [...] } }

Browser SDK

import { BrowserSDK, AddressType } from "@phantom/browser-sdk";

const sdk = new BrowserSDK({
  providers: ["google", "apple", "injected"],
  appId: "your-app-id",
  addressTypes: [AddressType.solana],
  autoConnect: true,
});

references/nft-minting.md — NFT mint pages, Metaplex Core, compressed NFTs

Common Issues

| Issue | Solution |

|-------|----------|

| "appId required" | Add appId from Phantom Portal when using google/apple providers |

| Redirect not working | Allowlist redirectUrl in Phantom Portal |

| React Native crashes | Import react-native-get-random-values as FIRST import |

| Extension not detected | Use waitForPhantomExtension() with timeout |

| signTransaction error | Use signAndSendTransaction instead — embedded wallets don't support signTransaction |

Altllm Portal API Keys

by internet-court

×1

Use this skill when the user asks to list, create, inspect, update, disable, re-enable, or revoke AltLLM Portal API keys for external agents or applications. Do NOT use for wallet login, billing history, or payment links.

Use this skill when the user asks to log in or out with a wallet session, fetch a wallet sign-in challenge, verify an externally signed challenge, or troubleshoot AltLLM Portal wallet login for the local altllm CLI. Do NOT use for API key management, billing history, or payment links.

Use this umbrella skill when the request spans multiple AltLLM Portal CLI domains, or when you need to navigate the local altllm CLI in this repository across auth, API keys, billing history, NOWPayments payment links, and related x402 Portal top-up guidance.
