Neither product holds a private key or signs on anyone's behalf. Evidence, policy, authorization, execution and settlement are separate facts; an integrity check alone does not establish authorization or on-chain settlement. The open-source tools are Apache-2.0 and read-only; the hosted applications and their operational services are proprietary. No independent audit or npm-registry package publication is claimed.

Read the repository's SECURITY.md before reporting a vulnerability. Never send seed phrases, private keys or signing requests.
