twzrd-x402-gate@0.13.1
Buyer-side x402 trust gate: free preflight before signing USDC on Solana + Base mainnet (eip155:8453). By default no signing if preflight is down; TWZRD_FAIL_OPEN overrides. Other EVM: unscored.
AI Security Review
scanned 2d ago · by lpm-firewall-aiThe package’s only lifecycle script is a release-time verification script, and the inspected runtime behavior is tied to explicitly invoked x402 gating tools. Delivery capture sends limited payment and delivery observations to the package’s intel service and is described in source; no unrelated collection or attack behavior was found.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
A user runs the safe-fetch CLI for a URL; importing the package does not trigger that CLI path.
Impact
No malicious behavior identified. The observed data and external tool invocation are tied to the package’s stated payment-gating features.
Mechanism
The CLI sends preflight data to the configured intel service and, if allowed, invokes AgentCash through npx. After payment, it can post a delivery observation to the intel service.
AI rationale
The package’s only lifecycle script is a release-time verification script, and the inspected runtime behavior is tied to explicitly invoked x402 gating tools. Delivery capture sends limited payment and delivery observations to the package’s intel service and is described in source; no unrelated collection or attack behavior was found.

Decision evidence
public snapshotAI called this Clean at 94.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The manifest has no install lifecycle hook; its only lifecycle script is prepublishOnly running release verification.
- The safe-fetch CLI invokes AgentCash through npx as part of its documented payment flow, and its entry code runs only when executed directly.
- Delivery observations are described as passive evidence from a completed paid request, with no response bodies shipped.
- The observation contains payment and delivery fields, and preflight requests go to the configured intel service.
Evidence against
- Running safe-fetch can download and execute agentcash@latest through npx, but this occurs within the user-invoked CLI payment flow.
- Runtime preflight and delivery observations send request-related data to the package’s intel service; the source describes the delivery capture and its data scope.
