Crank Protocol

create_agent_wallet

Creates an AgentWallet record keyed by agent_id and applies a policy preset. policy_preset: conservative | balanced | aggressive; omitted = balanced. This is a changeable default, not a cap: edit limits later with set_wallet_policy. unlimited=True starts the wallet with NO policies and records that explicit choice in the decision journal; passing both a preset and unlimited=True is rejected. default_policies is the legacy alias of policy_preset. wallet_address is the agent's PUBLIC key (caller-supplied); omit it to provision managed signing. Returns wallet_address, agent_id, status, applied_policies and policy_summary (applied limits + how to change them).
