AUREON is an AI-native financial intelligence protocol built on Robinhood Chain that provides automated portfolio and treasury management infrastructure for on-chain applications and AI agents. The protocol allows users to define target portfolio allocations and continuously monitors their assets for allocation drift. When portfolio weights move away from predefined targets, AUREON can calculate and execute the required trades to restore the desired allocation. The protocol combines automated rebalancing, portfolio monitoring, risk controls, smart-contract execution and cryptographic transaction verification. AUREON is designed to reduce the need for constant manual portfolio management while providing transparent and auditable on-chain execution.
