Order fully filled
Completed on the exchange’s side in one or more trades, and the balance reflects the full amount.
Built-In Crypto Exchange
Built-In Crypto Exchange
Buy or sell either currency in a pair, fiat to crypto, crypto to fiat, or crypto to crypto, at a live market price. Whichever field is typed into is fixed exactly; the other side is always an estimate.
Every order, accounted for
Four outcomes, never a silent one
An order isn’t the same thing as a completed trade. Whichever way it goes, the customer sees exactly where it stands.
Completed on less than requested
The difference is returned to the account balance rather than left pending indefinitely.
Still working on the exchange side
A known number of trades have filled already, and more may follow before it finally closes.
Order didn’t complete
Available and pending balances are rolled back in full, with a specific reason shown.
Outside of a full execution, the customer always sees a plain explanation of where the order stands and, where it matters, what happens to their balance.
Common error states
Specific messages for specific problems
Not enough to sell
Can happen if orders fire from different tabs at once. The one that no longer fits is rejected cleanly.
Currency pair unavailable
The selected pair currently isn’t supported for trading.
An account isn’t active
The from or to account’s status is invalid at the moment the order is placed.
No matching account
Shown if the currency the order needs doesn’t have a matching account behind it.
Too small to be worth trading
If the estimated buy amount wouldn’t cover the fee, the order is stopped before it’s created.
Something went wrong
A generic message covers rarer backend or provider errors, with a direct line to support.
How it actually works
Priced live from Kraken’s own order book
Pairs are pulled from the connected exchange and filtered down to the currencies your customer’s accounts can actually support, so the picker never shows a pair that has nowhere to settle.

While typing
A live, recalculating estimate
The opposite field updates continuously as the market price moves, so nothing is fixed yet.

At confirmation
One number, fixed and reserved
The typed side is locked exactly and the balance is reserved before the order reaches the exchange.

Frequently Asked Questions
What happens if I type the amount I want to receive instead of what I’m spending?
Typing into the From field fixes exactly that amount to be sold. Typing into the To field calculates the amount to sell at the live price, and that calculated amount is what’s actually fixed and spent, not the number typed.
What order types are supported?
Market orders only, which execute near-instantly at the live price. Limit orders exist in the underlying exchange but aren’t exposed to customers yet.
What happens if an order is only partially filled?
The filled portion is credited as it happens. If the exchange can’t fill the remainder, the order is closed automatically and the unfilled amount is returned to the balance it came from.
Can a customer choose which account to trade from?
Yes. If more than one account shares that currency and carries the crypto-exchange product, all of them appear so the right one can be picked.
What if the destination account doesn’t exist yet?
A Create new prompt appears in its place. The rate and estimated amount are still visible, but the order can’t be placed until the account exists.
Why does the confirmation screen warn about volatility?
Because the market price can move between confirmation and execution: cryptocurrency prices are volatile, and the value of the order can increase or decrease rapidly in that window.
How is an order confirmed as complete?
Status moves from Initiated through Open to Executed or Executed Partially as fills complete, with each underlying fill visible as its own transaction.
