How to Check a MetaMask Transaction on Etherscan?

Accessing the Transaction Hash

1. Open MetaMask and navigate to the Activity tab.

2. Locate the specific transaction you wish to verify—either a sent transfer, token approval, or contract interaction.

3. Click on the transaction entry to expand its details.

4. Find and copy the Transaction Hash (a 66-character alphanumeric string beginning with '0x').

5. Ensure the hash is copied in full without leading or trailing spaces.

Navigating Etherscan Interface

1. Go to https://etherscan.io using any modern browser.

2. Paste the copied transaction hash into the main search bar at the top of the page.

3. Press Enter or click the magnifying glass icon to initiate the lookup.

4. If the transaction exists on the Ethereum mainnet, Etherscan will load a dedicated page showing all on-chain metadata.

5. Confirm the network selector in the top-right corner displays Ethereum Mainnet; otherwise, adjust it manually if checking a testnet transaction.

Interpreting Key On-Chain Fields

1. Status: Displays 'Success' in green or 'Fail' in red—indicating whether execution completed without revert.

2. Block Height: Shows the exact block number where the transaction was included; clicking it reveals full block context.

3. Timestamp: Lists the UTC time of inclusion, accurate to the second, aligned with the block’s production time.

4. From / To: Identifies sender and receiver addresses; for contract calls, the 'To' field shows the deployed contract address.

5. Gas Used by Transaction: Reflects actual computational units consumed—not the gas limit—and directly impacts fee deduction.

Verifying Contract Interactions

1. Scroll down to the Input Data section to view raw hex-encoded function call parameters.

2. Click Decode Input Data if available—Etherscan may auto-parse common ERC-20 or ERC-721 method signatures.

3. Check the Internal Transactions tab to inspect value transfers triggered by the smart contract logic.

4. Review the State Changes section to observe modifications to contract storage slots post-execution.

5. Cross-reference the Contract Source Code tab—if verified—to confirm the executed bytecode matches published Solidity.

Frequently Asked Questions

Q: Can I check a MetaMask transaction if I only have the recipient address?A: No. Without the transaction hash or block number, Etherscan cannot isolate a single transaction among thousands processed per block. The hash is mandatory for precise lookup.

Q: Why does Etherscan show “Pending” even after several minutes?A: This indicates the transaction has not yet been included in a block. It remains in the mempool due to low gas price, network congestion, or node propagation delay.

Q: What does “Reverted” mean in the Status field?A: It means the transaction executed but terminated abnormally—typically due to failed require() checks, insufficient balance, or out-of-gas conditions—leaving no state changes except gas consumption.

Q: Is it possible to view transactions from MetaMask on Sepolia via Etherscan?A: Yes—but only through sepolia.etherscan.io. The main Etherscan domain indexes Ethereum Mainnet exclusively; using the wrong subdomain yields no results.
