Kraken says it fixed the October 30 problem that prevented clients from connecting and submitting orders through web, mobile and API services. Scheduled maintenance later that day also ended, while the team continues to monitor separate deposit and withdrawal issues.
Crypto exchange Kraken said it resolved a connectivity problem affecting access to spot and derivatives trading on October 30. The company marked the incident resolved at 03:42 UTC on its official status page. The team had announced its investigation an hour earlier.
Which trading services were affected?
Kraken said clients could have trouble connecting to the platform or submitting orders through its website and mobile apps. REST, WebSocket and FIX connections were also affected; trading software uses these channels to exchange data and orders with the platform. The company’s list of affected services included derivatives cross-exchange transfers.
| Time | What the team reported |
|---|---|
| 02:42 | Investigating problems with connections and order submissions for spot and derivatives clients. |
| 02:55 | The investigation continued. |
| 03:42 | The incident was resolved. |
The times refer to published updates. Kraken did not specify how long each customer was unable to trade. It also did not disclose the technical cause, the number of affected clients or whether customers suffered financial losses.
At 02:51 UTC that morning, Kraken Support told a customer it was aware of the problem and actively investigating. Its reply linked to the incident page, where Kraken later confirmed the fix.

Trading reopened in stages during scheduled maintenance
After resolving the incident, Kraken announced separate website and API maintenance for later that day. The scheduled work, covering spot trading and Kraken Prop, began at 08:00 UTC. Kraken did not say whether the work was connected to the earlier disruption.
At 08:03 UTC, customers could cancel existing orders but could not submit new ones. At 08:04, the platform began accepting only limit orders that would sit on the order book without matching immediately; existing orders could still be canceled. At 08:06, customers could submit all order types again and the exchange could match buy and sell orders. The team declared maintenance complete at 08:09.
Kraken’s exchange trading rules call the first stage cancel-only and the second post-only. Customers use a limit order to buy or sell at a specified price or better. With post-only selected, the exchange cancels the order if it would immediately match an existing one. While the platform is in post-only mode, it rejects market orders and customers cannot trade immediately.
Kraken announced the start of separate derivatives maintenance at 08:01 UTC and its completion at 08:16. The team had warned that it would briefly accept only post-only orders after reopening while it finished its checks. The work covered derivatives interfaces, sign-on, APIs and cross-exchange transfers.
Kraken did not disclose what happened to individual orders from customers who encountered errors during the outage. Normally, the exchange reserves funds for an unfilled order until it is filled or canceled. When a trade executes, Kraken updates the buyer’s and seller’s balances; the trade is final.
Funding warnings and US Futures maintenance
As of 16:04 UTC on October 30, the general status page listed the website, Kraken app and derivatives services as operational. REST, FIX and WebSocket connections were listed as normal, while Unified WebSocket was shown as undergoing maintenance.
The team said FLOW deposits and withdrawals could still be delayed. It was monitoring a fix for SUI and listed INIT deposits and withdrawals as paused because of a network issue. It did not say whether all pending withdrawals had been completed.
Kraken’s US Futures execution provider has scheduled further maintenance from 23:30 UTC on October 30 to 01:30 UTC on October 31. Expected to last up to two hours, it covers CME Group’s 24/7 futures products and Bitnomial perpetual futures only.
Kraken says customers will be unable to place, modify or cancel orders, or close orders or positions, including through the API. Market data may also be affected. The work will not affect linear multi-collateral derivatives for non-US clients or any other products, according to Kraken.
