If you’re a developer, there’s a good chance you’ll need to check confirmations on the blockchain at some point. Whether you’re building a blockchain application or just need to check the status of a transaction, doing so programmatically is the way to go.
The first thing you’ll need is a blockchain explorer. A blockchain explorer is a website or application that allows you to view the contents of the blockchain. You can think of it like a search engine for the blockchain. Once you have a blockchain explorer, you can use it to check the status of a particular transaction.
For example, let’s say you want to check the status of a transaction with the following hash:
0x4e3bfb9f71bfc8b1f7cc09960a37a3d76faeaa0b4f2a5fda79c67b6d4a5cd948
If you enter this hash into a blockchain explorer, you should see something like this:
As you can see, this transaction has been included in three blocks so far, which means it has three confirmations.
Now, let’s say you want to check the confirmations programmatically. The first thing you’ll need to do is get the transaction data from the blockchain explorer. For our example, we’ll use the blockchain explorer provided by EtherScan.
Once you have the transaction data, you’ll need to parse it to get the number of confirmations. For our example, we can use the following code:
import json
tx_data = ‘{“status”:”1″,”confirmations”:”3″}’
tx_dict = json.loads(tx_data)
confirmations = int(tx_dict[‘confirmations’])
print(confirmations)
This code will print out the number of confirmations for the transaction (in this case, 3).

As you can see, checking the confirmations for a transaction is pretty straightforward. All you need is a blockchain
