TypeScript SDK for BlockRun - every frontier model behind one OpenAI-compatible client. Pay with a BlockRun API key or per-call in USDC. Smart routing picks the cheapest capable model. No rate limits.

AI Security Review

scanned 5d ago · by lpm-firewall-ai

The package has no install hook, and the wallet behavior inspected is tied to payment functionality or explicit wallet adoption. The scanner’s transfer finding does not establish an unsolicited or malicious transfer.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

A caller uses the SDK to make a request that receives a 402 payment requirement.

Impact

No unsolicited transfer or credential exfiltration was established.

Mechanism

The SDK signs a payment payload for the response’s requested recipient; discovered wallet files are read locally, and adopting one requires an explicit address.

AI rationale

Evidence

package.jsondist/index.cjsdist/index.js

Decision evidence

public snapshot

AI called this Clean at 94.0% confidence as Benign with low false-positive risk.

Evidence for AI clean decision

package.json lists build and development scripts but no install lifecycle hook.
The CommonJS entrypoint creates a payment payload only after receiving and parsing a 402 payment requirement; it uses the requested recipient and validates the resource URL against the configured API URL.
The ESM bundle’s wallet discovery reads wallet files locally. Its code requires an explicit address to adopt a discovered wallet, and the notice says adoption is deliberate.

Evidence against

The scanner’s wallet-transfer label is consistent with the SDK’s payment-signing feature; the inspected source did not show an unsolicited transfer or private-key transmission.
