Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The SDK exports a gasless transaction path that reads an Ethers signer's private key and transmits it to a remote service. A quote path additionally embeds that key in a request URL. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-13T23:15:56.704Z - **Finished:** 2026-09-13T23:16:54.812Z - **Download time:** 1036 ms - **Static scan time:** 1393 ms - **AI review time:** 55679 ms - **Total time:** 58108 ms The recorded confidence comes from the underlying analysis.

A quote path additionally embeds that key in a request URL. - **Trigger:** A consumer invokes a gasless contract call or requests a gasless quote with a signer exposing its private key. - **Impact:** The remote service can obtain a wallet signing key and control the associated assets. - **Evidence paths:** dist/contract/index.js, dist/utils/constants.js - **Review source:** ai\_review - **Reviewed:** 2026-09-13T23:16:54.812Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Private-key exfiltration through sponsorship API requests. - **Attack narrative:** When a gasless transaction is requested, the SDK accesses the local signer's private key and submits it as \`pk\` to the configured sponsorship endpoint. Its quote method also adds that key to the request URL. This exposes the caller's wallet key to the service and potentially to intermediary URL logs, enabling theft of assets. - **Rationale:** The package contains a concrete runtime path that extracts and transmits wallet private keys to a remote endpoint. This is credential exfiltration, not a necessary client-side transaction operation. - **Files touched:** dist/contract/index.js, dist/utils/constants.js - **Network endpoints:** https://gateway.verified.network/api/sponsor ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** Gasless contract calls extract the local signer's private key and send it to a remote sponsorship service., The sponsorship POST body includes the private key field., Quote requests also put the private key in a URL query string, which can expose it to URL logging. - **Evidence against:** The manifest has no npm install lifecycle hook., No child-process or local filesystem harvesting behavior was found in the executable JavaScript reviewed., The flagged Vault file is a declarative contract ABI, not an executable payload. ## Affected versions and remediation This report applies to @verified-network/verified-sdk@2.9.0. - Avoid installing @verified-network/verified-sdk@2.9.0. 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.
