To see the status of a transaction on a blockchain, use a tool known as a blockchain explorer. This tool lets you view details of transactions, addresses, and blocks within a specific blockchain.

Here's a simple guide:

1. Obtain Transaction Hash: Get the Tx Hash from your wallet.
​
​2. Pick a Blockchain Explorer: Use Etherscan for Ethereum, Polygonscan for Polygon, etc.

3. Search & Review: Enter the transaction hash in the explorer.

4. Check its status (confirmed, pending, failed).

5. Interpret Status

For example, on Polygonscan and other EVM-based blockchain explorers, you will see something similar to the picture below.
