Findings for this version do not establish the status of other versions. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. The main export and package manifest show no install-time behavior, and the flagged JWT flow validates a Xaman token before sending it to Xaman’s own issuer. The network and lazy-loading behavior inspected matches the package’s wallet and Xahau runtime purpose. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 94.0% - **Started:** 2026-10-31T07:03:35.095Z - **Finished:** 2026-10-31T07:04:40.897Z - **Download time:** 2549 ms - **Static scan time:** 10421 ms - **AI review time:** 52831 ms - **Total time:** 65802 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** No attack was identified. Network and credential handling fit the browser wallet package’s authentication and ledger features. - **Trigger:** The host application imports the package; wallet authentication or Xahau operations occur when the host application invokes those features. - **Impact:** No unauthorized collection, account action, or other malicious impact was found. - **Review source:** ai\_review - **Reviewed:** 2026-10-31T07:04:40.897Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The observed Xaman JWT is validated and sent to Xaman’s own userinfo endpoint. Wallet reconnect and modal startup depend on explicit options. - **Rationale:** The main export and package manifest show no install-time behavior, and the flagged JWT flow validates a Xaman token before sending it to Xaman’s own issuer. The network and lazy-loading behavior inspected matches the package’s wallet and Xahau runtime purpose. - **Network endpoints:** oauth2.xumm.app, xumm.app ### Review decision - **Verdict:** Clean - **Confidence:** 94.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** The manifest has no install lifecycle hook; its only script is a build script., The ESM entrypoint adds a Buffer polyfill and re-exports the client package., Xaman JWT verification checks token scope and expiry, then sends the token to the Xaman issuer’s userinfo endpoint., Reconnect and modal auto-opening are controlled by options passed to createWalletKit., The lazy Xahau loader imports the runtime asset only when its protocol loader is used. - **Evidence against:** The bundle includes network requests and dynamic loading, which explain the scanner’s flags but are used for wallet, authentication, and Xahau runtime functions. ## Affected versions and remediation This report applies to @xrpl-wallet-kit/browser@0.3.0. - Review the evidence and your use of @xrpl-wallet-kit/browser@0.3.0 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
