Best A2A Coordination · ERC-7710 Redelegation
Agent-to-Agent Coordination
You sign one root delegation to a Coordinator smart account. The Coordinator fans out narrower, specialised delegations to worker sub-agents — each with a tighter scope and smaller budget. Revoke the root and the entire fleet loses authority instantly.
