## Security analysis

### Published attack-surface review

- **Summary:** No confirmed attack surface beyond user-invoked Ethereum utility functions. Installation has no lifecycle execution, and runtime modules perform local hashing, serialization, address, and ECDSA operations.

- **Trigger:** Consumer imports and explicitly calls exported utility functions.

- **Impact:** No credential collection, file mutation, network communication, persistence, or remote code execution established.

- **Evidence paths:** package.json, src/index.ts, src/hash.ts, src/signature.ts, src/account.ts, dist/index.js

- **Review source:** ai\_review

- **Reviewed:** 2026-08-11T13:05:06.485Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** Local Ethereum cryptography and byte/serialization utilities.

- **Rationale:** Source inspection shows a conventional Ethereum utility library with no install-time execution or concrete malicious behavior. Scanner-adjacent entrypoint imports are package-aligned local exports and crypto dependencies.

### Review decision

- **Verdict:** Clean

- **Confidence:** 99.0%

- **Recommended action:** mark\_clean

- **Intent class:** Benign

- **False-positive risk:** Low

- **Evidence against:** package.json has no lifecycle hooks or bin entry., src/index.ts only re-exports utility modules., src/hash.ts performs local Keccak/SHA-256/RIPEMD-160 hashing., src/signature.ts performs local ECDSA signing and recovery., Source and dist imports are limited to local modules and crypto/serialization dependencies., No filesystem, process/env, network, shell, eval, or dynamic-loading primitives found.

## Public findings

### 1. Low: Scripts Present
- **Category:** Manifest
- **Confidence:** 100.0%
