Portir lets anyone own tokenized US stocks on BNB Chain the way they would buy a mutual fund: pick a stock or a basket, set an amount, and let an agent buy only when the market is open and the price is fair. Every order passes the Guard first, and every decision the agent makes is written on-chain with a one-sentence reason.
