Use the phantom MCP server to interact with the user's Phantom wallet directly.
| Tool | Description |
|---|---|
get_wallet_addresses | Get blockchain addresses (Solana, Ethereum, Bitcoin, Sui) for the connected wallet |
sign_transaction | Sign a transaction (base64url for Solana, RLP hex for Ethereum) |
transfer_tokens | Transfer SOL or SPL tokens on Solana — builds, signs, and sends the transaction |
buy_token | Fetch Solana swap quotes from Phantom API; optionally sign and send |
sign_message | Sign a UTF-8 message with automatic chain-specific routing |
The phantom MCP server requires a PHANTOM_APP_ID environment variable from Phantom Portal. On first use, it opens a browser for OAuth authentication via Google or Apple login.
| Chain | Networks |
|---|---|
| Solana | mainnet, devnet, testnet |
| Ethereum | Mainnet, Sepolia, Polygon, Base, Arbitrum |
| Bitcoin | Mainnet |
| Sui | Mainnet, Testnet |
Networks use CAIP-2 format (e.g., solana:mainnet, eip155:1).
Ask the phantom MCP to retrieve the user's wallet addresses, then use them for transactions.
Use transfer_tokens to send SOL to a recipient address. The MCP handles transaction building, signing, and submission.
Use sign_message for wallet verification or authentication flows. The MCP routes to the correct chain based on the network parameter.
