Zerion — Off-chain Signing

Produce signatures without broadcasting a transaction. Used for login flows, permits, and signed orders. The signature is the output — you hand it to the verifying party (a dapp, relayer, exchange, etc.).

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. Signing requires an agent token (used as the wallet passphrase). For setup → zerion-agent-management.
