Kraken is a cryptocurrency exchange. Sure connects to Kraken using a read-only API key and imports your combined crypto holdings and spot trade history.
What is imported
Sure imports one combined Crypto exchange account per Kraken connection, containing:
- Current crypto holdings and balances
- Spot trade fills (buy/sell history)
Setting up Kraken
Step 1: Create a Kraken API key
- Go to Kraken API settings.
- Create a new API key with the following permissions only:
- Query Funds
- Query Closed Orders & Trades
Do not grant trading, cancellation, withdrawal, export, ledger, Earn, staking, or transfer permissions. Sure only imports balances, holdings, and spot trade fills. Granting write permissions is unnecessary and a security risk.
- Copy the API Key and Private Key shown after creation.
Step 2: Add the connection in Sure
- Go to Settings → Providers.
- Find the Kraken section.
- Enter a connection name, paste your API Key and Private Key, and save.
- Sure begins syncing your Kraken exchange account automatically.
Step 3: Import the account
After the first sync, your Kraken exchange account appears in the setup queue. Click Import Account in the provider panel to add it to your account list.
Multiple connections
If you have multiple Kraken accounts, add a separate named connection for each one. Each connection imports one combined crypto account.
Troubleshooting
Credentials need updating
If the connection shows a reconnect prompt, your API key may have been revoked or the credentials may have expired. Generate a new API key from Kraken and update the connection in Settings → Providers → Kraken.
No accounts found
After adding a connection, wait for the first sync to complete. If no accounts appear after syncing, verify that your API key has the Query Funds permission enabled.
Balance shown as approximate
When the exact exchange rate for a given date is unavailable, Sure shows the balance as approximate. The balance updates to the exact figure on the next sync when rate data becomes available.
