The skill is a disclosed crypto payment tool, but its optional hot-wallet mode can load local or environment wallet keys and broadcast irreversible transfers, so it belongs in Review before installation.
Install only if you intend to use a crypto payment bridge and understand the difference between the default keyless flow and Mode B. Avoid Mode B unless you are comfortable letting the agent process access a low-balance hot wallet; prefer paying from your own wallet, hardware wallet, or exchange withdrawal. Do not keep valuable wallet private keys or passphrases in project .env files, and treat --send with --yes as capable of moving real funds.
