Limited availability for blockchain transaction IDs
Blockchain transaction IDs are only available for recent transactions (from the last 2-3 months) and cannot be found in the ledger. If you will require your blockchain transaction ID at a later date, then we suggest storing a copy of your blockchain transaction ID in advance.
A blockchain transaction ID can be used to retrieve information such as the sending/receiving address, how many confirmations your transaction has and when the funds were sent. Follow these steps to find a deposit/withdrawal blockchain transaction ID on your Kraken account:
1. Sign in to your Kraken account and go to "Funding".
2. Scroll down past “Account Balances” to your “Funding Transactions”. Here you will find your most recent deposit and withdrawals. Find the entry that you want the transaction ID for and then click its corresponding purple “ID” link.
3. A pop up window will appear showing the transaction details. The transaction ID is the at the bottom and in the red box in the screenshot below (the full details are blocked out due to privacy). You can use this process to find transaction IDs for both deposits and withdrawals.
