The same advisory and Firewall decision cover these 2 recorded versions: 0.2.1, 0.2.2. - Avoid installing @2oolkit/hyperliquid-cli@0.2.2. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1. High: Osv Malicious Advisory - **Category:** External Intel - **Confidence:** 100.0% The package is advertised as a neutral CLI/MCP wrapper for Hyperliquid, but its distributed code silently routes value from the installer to an author-controlled address. In dist/index.js and dist/mcp.js, the constants BUILDER\_ADDRESS = 0xa6f967d47c6f85a5ba4fc43543e5e1c171cccf98, BUILDER\_FEE = 1 (0.01%), and REFERRAL\_CODE = '2OOLKIT' are hardcoded. On \`config init\` / \`config set --private-key...\`, a fire-and-forget \`silentAutoSetup(env, privateKey, walletAddress)\` signs and submits (a) a \`setReferrer('2OOLKIT')\` transaction and (b) an \`approveBuilderFee(0xa6f9...cf98, '0.1%')\` transaction on the user's Hyperliquid account, with errors swallowed so the user sees no indication. Additionally, \`HyperliquidClient.placeOrder\` unconditionally injects \`action.builder = { b: BUILDER\_ADDRESS, f: BUILDER\_FEE }\` into every order, so every trade routed through the CLI pays a builder fee to the hardcoded address in perpetuity. None of this is disclosed in the README or command output, there is no opt-out, and the behavior is triggered by the documented setup flow. This is a silent-relay pattern causing direct, ongoing financial harm to anyone who installs and uses the package with a funded wallet. The repeated POSTs flagged in dist/index.js:610 and dist/mcp.js:466 correspond to the Hyperliquid exchange submissions carrying these hardcoded builder/referrer fields. ## Dependencies and install lifecycle - **Lifecycle scripts present:** No - **Dependencies:** 5 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 7 - **Published dependency-graph edges:** 5 ### Published dependency entries - @modelcontextprotocol/sdk ^1.27.1 (Dependency) - @msgpack/msgpack ^3.0.0-beta2 (Dependency) - commander ^13.1.0 (Dependency) - ethers ^6.13.5 (Dependency) - zod ^3.24.0 (Dependency) ## Package metadata - **Package:** @2oolkit/hyperliquid-cli - **Ecosystem:** npm - **Version:** 0.2.2 - **License:** MIT - **Version published:** Not available - **Package first seen:** 2026-06-30T15:00:00.099Z - **Package last seen:** 2026-06-30T15:00:00.099Z - **Known versions:** 2 - **Latest version:** 0.2.2 - **Appeal under review:** No - **Description:** CLI & MCP server for Hyperliquid DEX — trade perpetuals & spot, manage orders, and query market data - **Author:** haeminmoon - **Maintainers:** haeminmoon - **Keywords:** hyperliquid, cli, mcp, dex, trading, perpetuals, perps, spot, orderbook, crypto, defi, onchain - **Runtime engines:** node: \>=20 - **Artifact files:** 11 - **Artifact unpacked size:** 376,795 bytes - **Artifact signatures:** 1 - **Attestations:** No ## References - [HTML security report]() - [Repository]() - [Homepage]() - [Issues]() - [OpenSSF/OSV advisory]() - [PACKAGE]() - [PACKAGE]()
