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 wallet-related scanner finding resolves to caller-triggered x402 payment behavior, with destination and amount taken from the payment challenge. The manifest has no install hook, and wallet migration is tied to explicit setup with adoption requiring an address.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

A caller makes an API request and receives an HTTP 402 payment challenge.

Impact

The inspected path supports the package's payment function; it does not establish a publisher-directed wallet drain.

Mechanism

The SDK signs a time-limited USDC authorization using the caller's configured wallet and the challenge's recipient and amount, then retries the request.

AI rationale

Decision evidence

public snapshot

AI called this Clean at 96.0% confidence as Benign with low false-positive risk.

Evidence for AI clean decision

package.json routes imports to the two inspected distribution entrypoints and lists build and development scripts, with no install lifecycle hook defined.
The payment helper signs a time-limited USDC authorization from the caller's wallet to a recipient supplied to the helper; the ESM entrypoint checks the requested asset.
In the CommonJS entrypoint, payment signing is reached after an HTTP 402 response. The recipient and amount come from the response's payment requirements.
Wallet migration scanning is part of the explicit new agent wallet setup flow; migration lists discovered addresses, and adopting a wallet requires an address.
