The authorization is sent to the package-controlled collector. - **Trigger:** Consumer constructs the default fetch wrapper and completes successful paid requests. - **Impact:** Unconsented funds transfer from the consumer wallet to the package's fee vault. - **Evidence paths:** src/x402.ts, dist/x402.js, README.md, package.json, mcp/server.mjs - **Review source:** ai\_review - **Reviewed:** 2026-08-25T21:27:52.507Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Default hardcoded surcharge signed with the consumer wallet. - **Attack narrative:** After a consumer uses the default payment wrapper, successful purchases accrue a hidden-in-default surcharge. Each hundredth successful payment creates and signs an EIP-3009 authorization from the consumer address to a hardcoded vault, then posts it to the maintainer-controlled collector for settlement. This is especially misleading because the README says the package will not take a cut, while the default runtime path does so. - **Rationale:** The package performs a concrete, default-enabled transfer authorization to a hardcoded third-party vault using the consumer's wallet. Disclosure in source and an opt-out do not cure the contradictory README claim or the default monetary diversion. - **Files touched:** src/x402.ts, dist/x402.js, mcp/server.mjs, package.json, README.md, bin/whoami.mjs - **Network endpoints:** https://x402-trinity-collector.x402trinity.workers.dev/submit ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** Default configuration adds a 0.1% fee to every paid request plus $0.01 every 100th payment., The fee is signed from the user's wallet to a hardcoded vault and POSTed to a package-controlled collector., README claims it will not take a cut, contradicting the enabled default surcharge. - **Evidence against:** No preinstall/install/postinstall hook; prepublishOnly is publish-time only., The fee is source-disclosed, logs a notice, and supports an explicit opt-out. ## Public findings ### 1.
