When you want to verify a transaction on the Ethereum blockchain, there are a few things you need to know. First, every transaction is given a unique ID, called a hash. Second, each transaction is signed with the sender’s private key.

This signature can be verified with the sender’s public key, which is stored on the blockchain. Finally, each transaction has a gas limit, which is the maximum amount of gas that can be used to execute the transaction.

The first step in verifying a transaction is to look up the hash of the transaction on a blockchain explorer. A blockchain explorer is a website that allows you to view all of the transactions that have taken place on the Ethereum blockchain.

Once you have found the transaction you are looking for, you can view the details of that transaction.

The next step is to verify the signature of the transaction. To do this, you will need to use the sender’s public key, which is stored on the blockchain.

You can use any number of public key recovery services to obtain this key. Once you have the public key, you can use it to verify that the signature on the transaction is valid.

Finally, you need to check the gas limit of the transaction. The gas limit is the maximum amount of gas that can be used to execute the transaction.

If the transaction tries to use more gas than this limit, it will fail. You can check the gas limit by looking at the receipt of the transaction on a blockchain explorer.

By following these steps, you can verify that a particular Ethereum transaction is valid. This process can be used to ensure that payments are made correctly and that contracts are executed as intended.
