What is a transaction ID?
Once you've sent a digital currency payment from CoinJar to an external address, that transfer's details (amount sent, sending/receiving address, as well as the date of transfer) can be found on the blockchain. This information is then publicly available, and given its own transaction ID - or TXID.
Transaction IDs are safe to share - no personal information is sent from your CoinJar to the blockchain.
How are transaction IDs useful?
At times, the recipient of your transfer may request a transaction ID from you - typically to confirm you've sent the payment successfully.
Digital currency transactions on the blockchain will also provide proof of a successful transfer. If you need to prove or check that a transaction has been processed by that currency's blockchain, the transaction ID will provide a direct link to those transfer details. Typically, a transaction's status can be determined by the number of confirmations it has received on the blockchain.
Finding a transaction ID on the blockchain
Because blockchain activity for most digital currencies is available publicly, there may be multiple different websites that can provide you with a way to explore that blockchain. For example, we've included some popular blockchain explorers below:
- Bitcoin - blockchain.info
- Ethereum - etherscan.io
- Litecoin - insight.litecore.io
- Ripple - xrpcharts.ripple.com
Regardless of the site you choose, the following steps can be used for most blockchain explorers.
- In the 'Search' area of the blockchain explorer, you'll need to enter information that is specific to your digital currency transaction. Typically, the receiving digital currency address you made the payment to is the best place to start.
- Provided the details you've entered are accurate, you'll be shown a list of all transactions that involve that receiving address.
- If there are a large number of transactions listed, the easiest way to navigate to your particular transaction is to look for the exact amount sent.
- Having found and selected your transaction, the transaction ID will typically be displayed as a long string of letters and numbers. You can copy this transaction ID - or your web browser's URL - to share with another person.
Tip: If you're looking through a long list of transactions, your can use your browser's Find feature to search for the exact digital currency amount you sent. This is usually under 'Edit > Find', or you can use the keyboard shortcut Command + F (macOS) or Control + F (Windows).
Does CoinJar provide transaction IDs?
For the time being, transaction IDs are not displayed within CoinJar itself, and must be obtained by searching for the transaction on a blockchain explorer website.
If you have any trouble locating a transaction ID, please don't hesitate to contact support for assistance.
