📝 WalkthroughWalkthroughThe web app adds SEP-10 transaction authentication alongside SEP-53 message authentication. The changes add server-signed SEP-53 challenges, SEP-10 challenge and verification endpoints, wallet selection and fallback logic, and authentication-method session fields.

Merge Risk: 🔵 Low · up to Some wallet failures can trigger an unnecessary second signing prompt, and a SEP-10 proof can be reused in a narrow restart window. These bounded issues warrant fixes or explicit acceptance before merge. Security Architecture ReviewSecurity architecture risk: 🟡 Moderate · up to The new wallet fallback appears to reject normally signed challenges, and its replay protection is not coordinated across server instances. Existing sign-in also now requires a configured server key. The available evidence does not establish a way to authenticate as another wallet. Retained concerns

CWE: CWE-294 — Authentication Bypass by Capture-replay
Clear the SEP-10 challenge from the session after successful verification.
claimAuthChallenge and consumeAuthChallenge keep replay state in process memory. If the process restarts before expiresAt, the session still contains the challenge, so the signed XDR can be submitted again. Delete the challenge before saving the authenticated session.
Proposed fix
+ delete session.challenge;
session.address = parsed.clientAccountID;📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
The signmessage pattern can send real failures into the SEP-10 fallback.
The regex on Line 84 matches any error message that contains signmessage. A wallet can raise an error such as "signMessage failed: locked" for a reason that has nothing to do with SEP-53 support. The code then treats that error as "SEP-53 unsupported" and starts the SEP-10 flow. The user sees a second signing prompt and loses the original error. Remove the bare signmessage pattern. Keep the explicit unsupported and not-implemented patterns.
Proposed fix
- return code === -3 || /(unsupported|not supported|not implemented|method not found|signmessage)/.test(message);
+ return code === -3 || /(unsupported|not supported|not implemented|method not found)/.test(message);📝 Committable suggestion
