The Guard
Session check, fair-price check, and the cheapest issuer across Ondo and bStocks. Above a 1% premium, the order is blocked and you are offered a better window.
Portir checks the US market session and the exchange price before every order, runs your plans only when the price is fair, and keeps loans against your stocks out of liquidation. Stocks, not tokens.
Start with $10When the exchange is closed, on-chain prices drift. Last night NVIDIA traded 1.4% above its close. Portir sees the premium, tells you in one sentence, and waits.

An agent on BNB Agent Studio runs your plans when the market is open and the price is fair, and repays your stock loan from your own buffer before it can be liquidated.
The app, an MCP server for Claude, and the agent all run one engine. Plans, rescues and their reasons live on-chain, readable by anyone.
Open the appThe Guard
Rio taps Buy on NVIDIA at midnight. This is what happens between his tap and the transaction. The same rules run in the app, in Claude, and inside the agent.
NYSE closed · opens in 5h 12m
Reads the US session and any halt from the Binance RWA Data API, then compares the on-chain price with the exchange reference.
Same stock, three issuers
Ondo, bStocks and xStocks list the same stock with different multipliers, halts and sessions. Portir picks the cheapest tradable one and shows what it compared.
One approval · one trade
The Binance Trading API quotes and builds the swap over PancakeSwap liquidity. Nothing is sent from a server; the record lands on BSC.
Plans
Pick a stock or a basket and an amount. Every 15 minutes the agent checks the market; it buys only when the exchange is open and the price is fair, pays from your wallet through PlanRegistry, and writes one sentence on BSC about why.
Waits for the open
Due at 3 AM in Jakarta? The agent holds until New York opens and the on-chain price is back within 0.5% of the exchange.
One order, then done
Blocked because the premium is too high? Leave a one-time order. The agent buys once the moment it clears, then the order closes.
AI & Semis · Big Tech · Dividends · US market
Four curated baskets. The agent never takes more than the plan amount per run, and your shares land in your own wallet.
Loan Guard
Put your stocks to work as collateral and borrow USDT. If the price drops, the agent repays part of the loan from your own safety buffer before you get anywhere near liquidation.

See what the agent does
Each plan and each loan has its own flow in the app. Every node is a real step the agent takes; the last run lights up where it stopped, with the reason in plain words.
