Paradigm and Tempo open source Centaur, a self-hosted agent runtime for secure multi-user workflows

176M agent-payment txs already makes the missing piece obvious: agents need a permissioned runtime before you hand them wallets, RPC keys, or Slack-level context. Centaur’s edge-injected creds + isolated sandboxes pair neatly with Tempo MPP/x402, but the hard part moves to cross-org capability grants and auditability when one team’s agent starts paying another team’s agent for work. If this becomes the default, agent infra starts looking less like chatbot SaaS and more like exchange custody plumbing: boring boundaries first, autonomy second.
