The v2.0.1 release graduates the OAuth2 PKCE-based authentication from beta to stable and includes performance improvements.

What's new:

Faster wallet connections. The SDKs no longer fetch all organization wallets during the connection flow. Wallet resolution now uses a direct tag-based lookup, reducing latency — especially for accounts with many wallets.
More reliable token refresh. Access tokens are now refreshed synchronously before API calls instead of in the background, preventing rare cases where an expired token could reach the server.
Phantom Login and deep link providers (web SDKs). The React SDK and Browser SDK now support provider: "phantom" for authenticating with an existing Phantom account, and provider: "deeplink" for connecting via the Phantom mobile app. Use isPhantomLoginAvailable() (Browser SDK) or the useIsPhantomLoginAvailable hook (React SDK) to check availability.
signTransaction on the Server SDK. Sign a transaction without broadcasting it — useful when you want to broadcast via your own RPC, inspect the signed payload, or collect multiple signatures before submission.

To upgrade:

npm install @phantom/react-sdk@latest

The Phantom MCP Server and OpenClaw plugin now support text-mode authentication and include several usability improvements for AI agents.

New features:

Text-mode login. The phantom_login tool now accepts a displayMode parameter. Set it to "text" to receive the device authorization URL and code as text instead of opening a browser — useful for headless or remote environments.
Version reporting. get_connection_status now includes the MCP Server or OpenClaw plugin version in its response.

Updates:

Simplified tool inputs. walletId removed from get_perp_markets and transfer_tokens — the authenticated wallet is used automatically.
Lazy authentication in OpenClaw. Authentication is deferred until the first tool call, speeding up agent startup.
Hyperliquid withdrawal fix. Fixed the bridge provider identifier used in Hyperliquid spot withdrawals.

The full Phantom Connect SDK is now open source. Browse the source, file issues, and contribute:
