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 USDC amounts on merchant invoices — so it carries no hidden spread or markup.
USDC trades around the clock on global markets, so the USD value can drift between the moment you quote and the moment someone pays. crypt.pe invoices lock the USDC quantity for the quote window, so the payer always sends the exact amount you asked for — but the fiat-equivalent value of that USDC can still move with the market after it lands in your wallet. if you want your invoice value pinned to the dollar, price it in a stablecoin instead.
yes — create a tracked invoice on crypt.pe, enter the amount, and the exact USDC quantity is computed at that moment on Ethereum (ERC-20), BNB Chain (BEP-20), Solana (SPL). 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 USDC you would use an exchange; to get paid in USDC at exact fiat pricing, a crypt.pe payment page does it with 0% platform fees.
usdc moves on 3 supported rails — Ethereum (ERC-20), BNB Chain (BEP-20), Solana (SPL) — and fees differ sharply between them. always send on the exact network shown next to the address at checkout; crypt.pe matches payments per chain, so the right rail is confirmed automatically.
