@blockrun/llm@3.23.0

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

Source inspection found wallet discovery and USDC signing, but these behaviors are tied to explicit wallet adoption and the SDK’s payment flow. The scanner’s wallet-transfer hint does not establish an automatic or unrelated transfer.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

A caller uses the SDK’s wallet discovery or payment features.

Impact

No automatic transfer to an unrelated recipient or other confirmed attack impact was established.

Mechanism

The SDK reads wallet files for discovery; adoption matches a caller-provided address. Payment signing uses the recipient and amount from the payment-required response and validates the resource URL against the client API URL.

AI rationale

Decision evidence

public snapshot

AI called this Clean at 93.0% confidence as Benign with low false-positive risk.

Evidence for AI clean decision

package.json selects dist/index.cjs and dist/index.js as the CommonJS and ESM entrypoints and lists build, development, and check scripts.
The CommonJS bundle’s wallet scanner reads wallet files to discover addresses and keys; the ESM bundle adopts a discovered wallet only after a matching address is provided.
The payment flow signs the recipient and amount from a payment-required response for the API request, with the resource URL validated against the client API URL.

Evidence against

The bundles contain private-key handling and USDC transfer-signing code, but inspected call sites tie it to the SDK’s payment flow; no automatic unrelated transfer was identified.
