## Findings

No findings.

## Files reviewed

- `dist/cjs/chains.js` (safe): No malicious patterns detected; the file only exports static Ethereum chain configuration data with no executable code, network calls, or filesystem access.
- `dist/cjs/common.js` (safe): No malicious patterns detected; the code implements Ethereum chain and hardfork parameter management without any suspicious behavior.
- `dist/cjs/crc.js` (safe): No malicious patterns detected
- `dist/cjs/eips.js` (safe): No malicious patterns detected; the file only exports a static data object describing Ethereum EIPs with no execution, network, or filesystem activity.
- `dist/cjs/enums.js` (safe): No malicious patterns detected
- `dist/cjs/hardforks.js` (safe): No malicious patterns detected
- `dist/cjs/index.js` (safe): No malicious patterns detected; the code is standard TypeScript/CommonJS re-export boilerplate.
- `dist/cjs/interfaces.js` (safe): The file contains only a CommonJS export marker and a source map comment with no executable logic or malicious patterns.
- `dist/cjs/types.js` (safe): No malicious patterns detected
- `dist/cjs/utils.js` (safe): No malicious patterns detected
- `dist/esm/chains.js` (safe): This file contains only static Ethereum chain configuration data with no executable code, network requests, or malicious patterns.
- `dist/esm/common.js` (safe): No malicious patterns detected; the code is a legitimate Ethereum chain/hardfork parameter management library without network, filesystem, or code-execution side effects.
- `dist/esm/crc.js` (safe): No malicious patterns detected; the file is a legitimate CRC32 implementation with only static data and pure calculation logic.
- `dist/esm/eips.js` (safe): No malicious patterns detected; the file is a static data module defining Ethereum EIP metadata and gas parameters with no external calls, dynamic execution, or file/network access.
- `dist/esm/enums.js` (safe): Cleared by Jev triage; no further analysis needed
- `dist/esm/hardforks.js` (safe): This file is a static Ethereum hardfork configuration data module with no executable logic, network calls, file system access, or suspicious patterns.
- `dist/esm/index.js` (safe): Cleared by Jev triage; no further analysis needed
- `dist/esm/interfaces.js` (safe): Cleared by Jev triage; no further analysis needed
- `dist/esm/types.js` (safe): No malicious patterns detected
- `dist/esm/utils.js` (safe): No malicious patterns detected; the code only parses Geth genesis JSON into EthereumJS-compatible parameters without any network, filesystem, process, or dynamic code execution activity.
- `src/chains.ts` (safe): No malicious patterns detected; the file only contains static Ethereum chain configuration data.
- `src/common.ts` (safe): No malicious patterns detected; the file is a legitimate Ethereum Common class implementation with no exfiltration, obfuscation, or unsafe behavior.
- `src/crc.ts` (safe): Cleared by Jev triage; no further analysis needed
- `src/eips.ts` (safe): No malicious patterns detected; the file only contains static Ethereum EIP configuration data and enum values with no network, filesystem, process, or dynamic code execution behavior.
- `src/enums.ts` (safe): Cleared by Jev triage; no further analysis needed
- `src/hardforks.ts` (safe): No malicious patterns detected
- `src/index.ts` (safe): Cleared by Jev triage; no further analysis needed
- `src/interfaces.ts` (safe): No malicious patterns detected; this file contains only TypeScript type and interface declarations for EthereumJS libraries.
- `src/types.ts` (safe): No malicious patterns detected; the file contains only TypeScript type definitions and interfaces with no executable code or suspicious behavior.
- `src/utils.ts` (safe): No malicious patterns detected; the file only parses and formats Ethereum genesis configuration data with no network, filesystem, process, or dynamic code execution activity.
