ercdata
Store, verify, and manage AI data on the Ethereum blockchain (Base network) using the ERCData standard. Use when an agent needs to store data fingerprints on-chain, verify data integrity, create audit trails, manage access control for private data, or interact with the ERCData smart contract. Supports public and private storage, EIP-712 verification, snapshots, and batch operations.

2 findings — 2 medium severity. This skill can be installed but you should review these findings before use.
W011: Third-party content exposure detected (indirect prompt injection risk)
What this means
The skill exposes the agent to untrusted, user-generated content from public third-party sources, creating a risk of indirect prompt injection. This includes browsing arbitrary URLs, reading social media posts or forum comments, and analyzing content from unknown websites.
Why it was flagged
Third-party content exposure detected (high risk: 0.80). The skill's CLI (scripts/ercdata-cli.py) and SKILL.md explicitly read on-chain entries via getData over the public Base RPC (DEFAULT_RPC https://mainnet.base.org), exposing the agent to arbitrary, user-generated blockchain data (public contract storage) that the docs recommend using for "agent-to-agent trust" and thus can materially influence agent decisions or actions.
W009: Direct money access capability detected (payment gateways, crypto, banking)
What this means
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.
Why it was flagged
Direct money access detected (high risk: 1.00). The skill explicitly interacts with the Base (Ethereum-compatible) mainnet and requires a private key (ERCDATA_KEY) plus a funded wallet for gas. Its commands (e.g., store, grant-access, revoke-access, register-type, snapshot) are implemented via web3/eth-account and will create and sign on-chain transactions. Because it provides specific blockchain transaction signing/sending capability (wallet key usage and RPC to Base), it enables direct crypto/ blockchain financial execution (paying gas, signing transactions). Therefore it meets the "Direct Financial Execution" criteria.
