Test it

Using "starknet-wallet". Check the ETH balance for the configured agent wallet.

Expected outcome:

Balance check result: ETH balance 1.5, raw balance 1500000000000000000, 18 decimals. The response includes the wallet and token contract addresses.

Using "starknet-wallet". Prepare a 10 STRK transfer with gasless payment in USDC.

Expected outcome:

Validate the recipient address and token amount.
Confirm the paymaster endpoint, USDC fee support, and wallet balance.
Request approval before submitting the state-changing transaction.

Using "starknet-wallet". Create controls for an autonomous contract-calling session key.

Expected outcome:

Policy: allow only the approved contract and methods, enforce per-transaction and period spending limits, set an expiry, and document immediate revocation steps.

Security Audit

High Risk

v3 • 8/7/2026 Open versioned report

Most static findings are false positives caused by documentation links, Markdown or TypeScript template literals, and standard configuration reads. Private signing-key and paymaster-key handling are confirmed high-risk credential practices, and the skill also enables autonomous asset operations through transfers, contract calls, swaps, and session keys.

SKILL.md:285

Environment file access

signer: process.env.STARKNET_PRIVATE_KEY,

The skill requires a private signing key or paymaster API key through environment configuration. Exposure of these credentials can authorize asset transfers or consume paid services, although no exfiltration is shown here.

Agent-Controlled Asset Operations

The skill instructs an agent to transfer tokens, invoke state-changing contracts, execute swaps, and use session keys for autonomous operations. Misconfiguration or prompt compromise could therefore move wallet assets without per-action human approval.

The cited sections explicitly document state-changing wallet operations and autonomous session-key execution. The risk follows from the stated capability and does not depend on a heuristic pattern.

Capability review items (7)

These are real local capabilities that may be expected for this skill, so they require review but are not counted as confirmed malicious behavior.

What You Can Build

Agent Payment Operations

Give a payment agent repeatable balance checks and token transfer workflows with explicit recipient, token, and amount parameters.

Wallet Monitoring

Build portfolio checks that query several Starknet tokens and report formatted balances through the provided scripts or MCP tools.

Bounded On-Chain Automation

Plan contract calls, swaps, and session-key policies with spending limits, allowed contracts, expiry, and revocation controls.

Try These Prompts

Check One Balance

Check the ETH balance for wallet 0x... on my configured Starknet network. Return the token address, formatted balance, raw balance, and decimals.

Review a Transfer

Prepare a STRK transfer of 10 tokens to 0x.... First list the required checks, recipient, network, estimated fee, and approval points. Do not submit it yet.

Compare Portfolio Methods

Explain whether to use the single-token or multi-token balance workflow for ETH, STRK, USDC, and USDT. Include tradeoffs and expected response fields.

Design Session-Key Controls

Design a session-key policy for an agent that can call one approved contract, spend at most a defined amount per day, expires tomorrow, and can be revoked. Identify remaining risks.

Best Practices

Use a dedicated wallet with minimal funds for agent automation.
Verify network, recipient, token address, calldata, and fee payer before submission.
Store signing credentials in a managed secret system and rotate them when exposure is suspected.

Avoid

Do not place private keys in source files, prompts, logs, or shared environment dumps.
Do not allow unrestricted contract calls or unlimited spending for an autonomous agent.
Do not treat a quoted swap price, gasless option, or successful simulation as a final safety guarantee.
