@blockrun/llm@3.24.2

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 4d ago · by lpm-firewall-ai

The wallet-related matches are part of caller-invoked payment handling: the signer uses recipient and amount values parsed from a 402 challenge. The manifest defines no install hook, and the inspected source does not establish an attack.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

A caller invokes the payment-enabled client and receives a 402 payment challenge.

Impact

The flow can authorize the requested payment from the caller wallet; inspected source does not establish an unrelated or automatic transfer.

Mechanism

The client parses the challenge recipient and amount, then signs a payment authorization.

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 selects the two inspected bundles and defines build and test scripts without an install hook.
Both bundles route a 402 response through payment requirement parsing before signing.
The EVM signer uses the wallet address, recipient, and amount supplied to the payment flow.
The parsed payment recipient and amount come from the payment requirement.
