twzrd-x402-gate@0.11.3

Security fixes in 0.11.4: a non-USDC asset could be priced as USD on the policy fetch wrapper, and Base Worker network spellings were skipped. Upgrade to 0.11.4.

Released identity 0.11.2. Buyer-side x402 trust gate: free preflight before signing USDC to a merchant. On Solana mainnet and Base mainnet (eip155:8453), a missing payTo is not approved, a buyer preflight outage does not sign unless TWZRD_FAIL_OPEN=true,

AI Security Review

scanned 5d ago · by lpm-firewall-ai

The package’s inspected automatic behavior is limited to release verification, and its runtime network requests support payment preflight. The flagged child-process use belongs to explicitly invoked CLI flows and does not establish malicious behavior.

Static reason

One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source

Trigger

The preflight runs when an application calls the gate or a user invokes a CLI; no install-time trigger was found.

Impact

The observed network and process actions support the package’s stated payment-gating purpose; no credential theft or unrelated data collection was identified.

Mechanism

The gate sends payment decision input to the configured TWZRD preflight endpoint. The safe-fetch CLI can then invoke AgentCash after approval.

AI rationale

Network endpoints1

intel.twzrd.xyz

Decision evidence

public snapshot

AI called this Clean at 95.0% confidence as Benign with low false-positive risk.

Evidence for AI clean decision

The only lifecycle script is prepublishOnly, which runs release verification; no install hook is declared.
The package entry point exports APIs, and the safe-fetch CLI runs its main function only when invoked as a CLI.
Payment preflight sends the decision input to the configurable TWZRD service, defaulting to https://intel.twzrd.xyz, which matches the package’s stated purpose.
The doctor says its refusal proof is local by default; live preflight is opt-in.

Evidence against

The explicitly invoked safe-fetch CLI spawns npx with the caller’s environment, as part of its documented AgentCash payment flow.
