Etherscan allows you to search and track the Ethereum blockchain for transactions, addresses, tokens, prices, and other activities taking place on the Ethereum blockchain. For links to the block explorers for other networks, scroll to the bottom. However, they all function very similarly, so the guidance below will probably also apply to whichever site you access.
To check your account details on Ethereum Mainnet, please enter your public address into the search bar on etherscan.io, and you will see all of your account activity and transaction details.
After you enter your MetaMask public address, which is on Ethereum mainnet, you will see the ETH balance in native value, today's fiat value and a separate total balance of all your custom ERC-20 tokens. You will also see all the up-to-date transactions in your wallet.
This balance should reflect in your MetaMask wallet. If you don't see your custom token, you need to add it manually following this article. If you're still having issues finding the tokens or your Ether balance isn't the same in your MetaMask wallet, see this article.
Note: if you deposit/send your token on a non-Ethereum Mainnet network you can check your balance and transactions on a different explorer:
- Binance Smart Chain (BSC): BscScan
- Polygon: PolygonScan
- Avalanche C-Chain: Snowtrace
- Arbitrum: Arbiscan
- Optimism: Optimistic Ethereum Explorer
- Harmony: Harmony Block Explorer
- Fantom: FTMScan
