React UI components and hooks for EmbarkAI authentication and Account Abstraction
AI Security Review
scanned 4mo ago · by lpm-firewall-aiStatic inspection found high-risk browser primitives, but they are consistent with the package's declared auth/account-abstraction UI purpose and are user/runtime invoked. Scanner claims of remote asset decode-execute and child_process were not substantiated in the inspected source.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
User imports UI kit and initializes Provider/auth wallet features.
Impact
No evidence of unconsented install-time execution, credential harvesting, exfiltration, persistence, or destructive behavior.
Mechanism
Product-aligned iframe auth, MPC/WASM signing, OAuth, local keyshare storage, and backup APIs.

Decision evidence
public snapshotAI called this Clean at 86.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- dist/iframe/main.js ships dkls23_wasm_bg.wasm and wasm-bindgen glue with new Function.
- dist/index.cjs creates a hidden auth iframe and exchanges postMessage requests for auth/signing flows.
- dist/index.cjs and dist/iframe/main.js read/write localStorage keyshares and auth/session metadata when user invokes wallet backup/auth flows.
Evidence against
- package.json has no preinstall/install/postinstall lifecycle hooks and exports only dist entrypoints/styles.
- No child_process, shell execution, destructive filesystem writes, or AI-agent control-surface writes found in package files.
- Network calls are aligned with auth, TSS, vault, KYC, OAuth, price, and cloud-backup product features.
- dist/iframe/main.js fetches local dkls23_wasm_bg.wasm via import.meta.url; no remote asset decode-and-execute path was confirmed.
- postMessage handlers check expected iframe origin or SDK message structure/HMAC before sensitive iframe actions.

Remote Asset Decode Execute
Source fetches a remote non-code asset, decodes its contents, and dynamically executes the decoded payload.
