Etherlink Skill

Security checks across malware telemetry and agentic risk

Overview

This appears to be a legitimate Etherlink blockchain helper, but it can give an external MCP server ongoing wallet-signing authority for real on-chain transactions.

Review the MCP server package before installing. Prefer read-only mode, test on Shadownet first, never use a primary wallet key, use a dedicated low-balance wallet, and manually verify the network, recipient, amount, contract, and gas before allowing any transaction to be signed.

Missing User Warnings

Medium
Confidence
95% confidence
Finding
The skill explicitly demonstrates sending on-chain transactions but does not warn that blockchain transfers are typically irreversible and can permanently lose funds if the recipient, amount, or network is wrong. In a blockchain skill, this omission materially increases the chance of harmful user actions because the feature directly handles value transfer.

Missing User Warnings

Medium
Confidence
98% confidence
Finding
The skill instructs users to place a private key in configuration but provides no warning about credential sensitivity, storage risks, or safer secret-management practices. Exposure of `EVM_PRIVATE_KEY` would allow an attacker or local compromise to sign transactions and drain funds from the associated account.
