PlumS reads the same stock across three venues and against the real US market, so the premium, the discount, the gap between venues and what a swap would cost are all visible in one place.
The gap
A premium means the tokenized stock trades above the real share price. A discount means it trades below. The two chains often disagree with each other as well, and that disagreement is its own signal, especially outside US trading hours.
The swap
Finding a gap is only half an answer. PlumS asks LI.FI, a routing aggregator, what buying at the cheapest venue would actually cost once fees, slippage and gas are counted, then shows that cost next to the gap it would have to beat.
LI.FI finds the route and executes it. PlumS never connects to your funds and never takes custody. Most of the time the route costs more than the gap is worth, and the panel says so instead of selling you the trade.
How it reads
Each stock's live price on BNB Chain through its bStocks pool, on Solana through the xStocks pair, and on Robinhood Chain through an executable Uniswap quote, so a thin pool cannot flatter the number.
The current US market price for the same underlying stock, pulled through Finnhub on the server so no key reaches the browser.
Each chain's premium or discount against the real price, plus the distance between the cheapest and dearest venue, recomputed on every refresh.
Five markets, four prices each, read live and shown side by side. Reading connects nothing; a swap is yours to start and LI.FI's to execute.
