Visit etherscan.io for detailed information about transactions on the Ethereum blockchain. You can input your wallet address or transaction hash to verify transaction history. It's an excellent way to validate a transaction's completion if you're unsure about the status.
If you are using MetaMask wallet, select the 3 dots at the top right, and select View on Etherscan to see all transactions on etherscan.io as well.
Transactions such as NFT sales, referrals, and royalty payments may sometimes be viewable under the "Internal Txns" tab on an Etherscan account page.
