Conversation
- Add multi-wallet support (Freighter, Albedo, LOBSTR) - Display truncated wallet address after connection - Add disconnect functionality with onDisconnect callback - Improve error handling with inline error messages - Add copy-to-clipboard and Stellar Expert link - Replace alert() with accessible error messages Closes: GuardZero144#67 Signed-off-by: waterWang <water.wang@users.noreply.github.com>

Someone is attempting to deploy a commit to the Josie's projects Team on Vercel. A member of the Team first needs to authorize it. |
WalkthroughChangesWalletConnect now supports Freighter, Albedo, and LOBSTR detection and connection. It provides wallet selection, connected-wallet actions, inline errors, accessibility feedback, and disconnect handling. The page clears its wallet state after disconnection. Tests cover the updated flows. Wallet connection flow
Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🟡 Moderate · up to The wallet connection change is not ready to merge because Albedo and LOBSTR connections may fail or produce an invalid address, and keyboard activation can start duplicate connection requests; the success message also cannot be dismissed immediately. These are bounded but concrete correctness and usability issues that should be fixed before merging. Sequence Diagram(s)sequenceDiagram

- Around line 199-203: Update the SuccessToast usage to provide an onDismiss
callback that sets showToast to false, allowing the close button to hide the
toast immediately while preserving the existing timeout behavior.
- Around line 222-231: Remove the onKeyDown handler from the native button and
rely on its existing onClick handler for Enter and Space activation. Preserve
the complete wallet-menu, single-wallet connection, and no-wallet error behavior
in onClick without adding a second activation path.
- Around line 79-91: Update the Albedo and LOBSTR branches in the wallet
connection handler to use typed adapters, read Albedo’s address from
result.pubkey, and access LOBSTR through window.lobstrSignerExtensionApi.
Validate that each adapter returns a non-empty address before storing it in
state, preserving the existing error behavior otherwise, and add success and
failure tests covering both providers.

Albedo Stellar wallet publicKey API response pubkey official documentation
💡 Result:
To retrieve a public key from the Albedo Stellar wallet, you should use the Albedo Intent library (@albedo-link/intent). This library provides a promise-based interface for interacting with the Albedo API [1]. The specific intent for retrieving a public key is public_key [1]. When called, this intent requests the account's public key, providing a secure method for authentication in Stellar-based applications [2]. ### Usage Example You can trigger the public key request using the following JavaScript pattern: javascript albedo.publicKey({ token: 'optional_verification_token' // Optional: random string for security/verification }) .then(res => { console.log("Public Key:", res.pubkey); console.log("Signed Message:", res.signed_message); console.log("Signature:", res.signature); }) .catch(err => { console.error("Error retrieving public key:", err); }); ### API Response Structure The public_key intent returns an object containing the following fields [2]: * pubkey: The user-selected public key (string). * signed_message: A HEX-encoded authentication message derived from the public key and the provided token (string). * signature: A HEX-encoded ED25519 signature of the authentication message, which allows you to verify that the user possesses the corresponding secret key (string). Parameters such as token (for verification) and callback (for asynchronous URL-based responses) are optional [2]. You can find further details and interactive examples in the Albedo playground or by reviewing the @albedo-link/intent documentation on npm [3][2].

LOBSTR Stellar signer extension API window.lobstrSignerExtensionApi getPublicKey official documentation
💡 Result:
The LOBSTR signer extension interacts with web applications through a global JavaScript object, window.lobstrSignerExtensionApi, which provides an interface to the LOBSTR wallet's functionality [1][2]. This API is part of the @lobstrco/signer-extension-api package, which developers can install from npm to facilitate communication with the browser extension [1][3]. The getPublicKey method is an asynchronous function exposed by this API that allows connected web applications to request the public key (Stellar address) from the user's LOBSTR wallet [4][5]. Key details regarding usage: Integration: Developers should use the @lobstrco/signer-extension-api npm package to integrate with the extension [1][2]. Global Access: Once the extension is present, it exposes a global variable, window.lobstrSignerExtensionApi, which contains the library methods [1][4]. Method Signature: The getPublicKey method is defined as follows [5]: getPublicKey: => Promise Example usage: if (await window.lobstrSignerExtensionApi.isConnected) { const publicKey = await window.lobstrSignerExtensionApi.getPublicKey; console.log("Connected public key:", publicKey); } The official source code and documentation for this API are maintained in the LOBSTR browser extension repository on GitHub [2][6].

Use documented Albedo and LOBSTR adapters.
Albedo returns the account in result.pubkey, so result.publicKey produces undefined. The component stores this value without validation and then throws in truncateAddress. LOBSTR exposes window.lobstrSignerExtensionApi, not window.lobstr. Add typed adapters, validate a non-empty address before updating state, and add success and error tests for both providers.

Wire the toast dismissal handler.
SuccessToast binds its visible close button to onDismiss, but this call does not provide that callback. The close button does nothing until the timeout expires. Pass onDismiss={() => setShowToast(false)}.

Remove the duplicate keyboard activation handler.
A native button already emits click for Enter and Space. This handler calls handleConnect before the native click, so a keyboard user can start two connection requests before isConnecting rerenders. It also does not show the no-wallet error for keyboard activation. Keep the complete behavior in onClick and remove this handler.
