Wallets by @metamask v1.0.0 C PASS 2 flags

General coding standards for MetaMask client repos: TypeScript-only new code, no `any`, naming, file layout, error handling, and the required- reading and enforcement checklist. Use when writing or refactoring application code, when deciding how to structure a new module, or when checking whether a change meets repo coding standards before opening a PR.

Capabilities below are detected automatically by an open-source scanner that reads the skill's text and scripts (see how this is computed). Not measured means the scanner couldn't make a confident call — it is NOT a green check, and you should treat it as a possible red flag until a human or a stronger scanner has measured it.

2 Red flags things this skill can do that affect your security or funds

⚠
Mutable remote runtime runs remote code that can change behavior without a local diff
⚠
Can install code installs software at setup time (npx, pip, brew, etc.)

8 Cleared by scanner we scanned the skill's text & scripts and found no evidence of these

✓
Requires private key you must hand over a private key, mnemonic, or wallet config
✓
Requires hosted operator depends on a third-party hosted service to function

Ingredients (services this skill talks to)

We did not find any well-known hosted services in this skill's text or scripts. This does NOT mean the skill is local-only — it might use services we don't yet recognize, or talk to them through code paths our scanner can't reach. A complete dependency list (every package, library, and binary, with integrity hashes) is on the roadmap; today we only show recognized hosts.

Audits

No one has audited this skill yet. That is different from “audited and clean” — it just means no professional reviewer (a security firm, the CryptoSkill team, or a verified independent researcher) has signed off on it. There are no audit reports to read. How reviewer levels work →
