Every transaction submitted to the Ethereum blockchain is assigned a unique number (TX).
You can check the status of your transaction using this number through one of the available blockchain scanners, such as Etherscan. To see details of the transaction, paste TX into the search field and click on the transaction's block number.
As time passes, the status of your transaction changes from "Unfinalized" to “Unfinalized (Safe)” and finally “Finalized”. The whole confirmation process should not take longer than 15 minutes.
