2 findings — 1 high severity, 1 medium severity. You should review these findings carefully before considering using this skill.
The skill handles credentials insecurely by requiring the agent to include secret values verbatim in its generated output. This exposes credentials in the agent’s context and conversation history, creating a risk of data exfiltration.
Insecure credential handling detected (high risk: 1.00). The prompt explicitly creates, prints, passes, and persists raw private keys and signer secrets (e.g., console.log('Private Key:', ...), PRIVATE_KEY=0x... in CLI examples, programmatic privateKey: '0x...', and plain-text credentials.json), requiring the agent to handle and output secret values verbatim.
The skill is specifically designed for direct financial operations, giving the agent the ability to move money or execute financial transactions — such as payment processing, cryptocurrency operations, banking integrations, or market order execution.
Direct money access detected (high risk: 1.00). The skill explicitly performs on-chain financial operations. It creates wallets and requires funding, contains scripts and API functions to detect balances, bridge and swap tokens (e.g., swapEthToUsdc, "Bridge/swap to get ETH on Optimism and USDC on Base", swap-to-usdc.js), and performs signed on-chain actions (registerFid, addSigner, EIP-712/EIP-3009 signatures for x402 payments). It also instructs storing private keys and automates transactions (registering FIDs, adding signers, making payments), and includes a payment address and signature header for on-chain token transfers. These are specific crypto/blockchain transaction capabilities (wallets, swaps, signing), so this skill grants direct financial execution authority.
