ACE Protocol is an Agentic treasury operating system built on Solana for recurring payments, reserve management, and autonomous cashflow coordination. ACE analyzes real wallet history, predicts recurring obligations, prepares payment queues, optimizes execution via Jupiter/Jito infrastructure, supports agentic x402/pay.sh payments, and enables privacy-preserving treasury operations through integrations like Cloak, QVAC, Ika, and Encrypt.
