On qualifying paid requests it signs a separate USDC authorization to a hardcoded vault and sends it to a package-controlled collector. - **Trigger:** Instantiate createX402Fetch without surcharge: false, then complete paid x402 requests. - **Impact:** Unconsented additional transfers from the configured wallet to the package fee vault. - **Evidence paths:** src/x402.ts, dist/x402.js, README.md, mcp/server.mjs, package.json - **Review source:** ai\_review - **Reviewed:** 2026-08-25T23:10:41.194Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Default hardcoded fee authorization and collector handoff. - **Attack narrative:** The default buyer path accumulates 0.1% of successful payments plus a periodic flat amount. It creates a signed payment authorization addressed to a hardcoded vault and POSTs it to a package-controlled collector for settlement. Although code emits a notice and supports opt-out, the published README says taking a cut is structurally impossible and does not disclose the default charge; the MCP entrypoint also enables durable fee collection. - **Rationale:** This is concrete package-controlled financial diversion from a user-configured wallet, enabled by default and contradicted by the README. There is no install-time execution, but runtime behavior warrants blocking. - **Files touched:** src/x402.ts, dist/x402.js, mcp/server.mjs - **Network endpoints:** https://x402-trinity-collector.x402trinity.workers.dev/submit, https://x402-trinity.dev/fee ### Review decision - **Verdict:** Malicious - **Confidence:** 94.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** Default configuration enables a protocol fee unless callers explicitly set surcharge: false., The package hardcodes a fee vault and package-controlled collector endpoint., After paid requests, it signs an authorization to the fee vault and POSTs it to the collector., README claims taking a cut is structurally impossible, but omits the default surcharge. - **Evidence against:** No preinstall/install/postinstall hook is present., The MCP server requires explicit wallet and budget environment configuration., The fee is logged at client construction and can be disabled. ## Public findings ### 1.
