Zerion — Agent Token & Policy Management

Agent tokens authorize the CLI to sign transactions on behalf of a wallet without a passphrase prompt. Policies attached to a token scope what the token can do (chains, allowlist, deny rules, expiry). This is the foundation for safe autonomous trading and off-chain signing.

Setup

If a zerion command fails with command not found, install once:

npm install -g zerion-cli

Requires Node.js ≥ 20. For auth see the zerion umbrella skill. To execute trades after setup → zerion-trading. To sign messages/typed-data → zerion-sign.
