the rate aggregates live order-book prices from major exchanges and refreshes every 30 seconds. it is a mid-market reference rate — the same feed crypt.pe uses to lock exact DOT amounts on merchant invoices — so it carries no hidden spread or markup.
Polkadot trades around the clock on global markets, so the GBP value can drift between the moment you quote and the moment someone pays. that is exactly why crypt.pe invoices lock the DOT quantity at creation time: a £100 invoice stays £100 regardless of what the chart does afterwards.
yes — create a tracked invoice on crypt.pe, enter the amount, and the exact DOT quantity is computed at that moment on Polkadot. the payer's wallet pre-fills it from the QR and the on-chain match marks it paid, with the fiat value recorded for bookkeeping.
no. this page only shows the live reference value — nothing is exchanged, no account is needed and no funds are touched. to actually sell DOT you would use an exchange; to get paid in DOT at exact fiat pricing, a crypt.pe payment page does it with 0% platform fees.
