What is an instant crypto exchange?

An instant exchange swaps one coin for another without asking you to open an account. You pick the pair, give the address the coins should arrive at, and send a deposit. When the deposit confirms, the payout goes straight to the address you gave.

What happens, in order

1. You choose what you are sending and what you want back. Swapcrypts quotes the amount before you commit to anything.
2. You give a payout address on the receiving network. This is the one thing that cannot be fixed later, so it is worth reading twice.
3. You are shown a deposit address and an amount. Nothing happens until that deposit arrives.
4. The exchange runs and the payout is sent. The order page shows each step and the transaction ids.

What it is not

An instant exchange is not a wallet and not a broker. Your coins are not held between orders. There is no balance, which also means there is nothing to withdraw and nothing to log in to.

That shape has a trade off worth understanding: because there is no account, the order page is the only link to your order. Keep it until the payout lands.
