Whoever asks "What is a blockchain explorer?" needs one idea first: an address is public, a key is not. A wallet address is the public string a wallet shows for receiving coins. Anyone who knows it can send to it, but only the matching private key can move what arrives. On public networks an address does reveal the balance and history behind it. For a player moving coins to and from a casino, reading an address correctly matters as much as reading the amount.
To track a bitcoin transaction, copy its transaction ID, also called the hash, from the wallet's history and paste it into a bitcoin explorer. The result shows whether the transfer is still waiting or already confirmed, how many confirmations it has gathered and what fee was paid. Confirmation time depends on how busy the network is and on the fee offered, so a low fee can leave a transfer waiting for a long while. Searching an address instead shows its balance and every transfer, open to anyone who has it.
A wallet that supports TRC20 lists TRON, or TRC20 by name, in its network menu for receiving and sending; support for USDT on some network is not enough. Checking takes a moment: open the screen for receiving USDT and read the networks offered. Such a wallet also needs a way to pay TRON fees, whether TRX held in it, energy and bandwidth covering part of each transfer, or TRX burnt when those run short. The expected fee appears before confirming, and the casino cashier lists the networks it accepts.
A blockchain explorer is a public website that reads a network's records and presents them in plain form: transfers, addresses, balances, fees and confirmations. Each network has its own, so a TRC20 transfer is looked up on a TRON explorer and a bitcoin transfer on a bitcoin one. Using a blockchain explorer needs no account, only a hash or address pasted into its search box. A screenshot proves nothing when the hash cannot be found there, while transfers inside one exchange may never reach the network and appear only in its own history.
Common questions
What is a blockchain explorer used for?
Reading a network's public records: transfers, addresses, balances, fees and confirmations, each network on an explorer of its own.
What is a wallet address?
The public string a wallet shows for receiving coins; anyone can send to it, but only the matching private key can move what arrives.
Can an address show which network it belongs to?
Not always. BEP20 and ERC20 addresses both start with 0x and can be identical, so the network is chosen from a menu, not read from the address.
What does a bitcoin wallet address look like?
A long run of letters and digits that usually starts with 1, 3 or bc1, depending on the address type.
What pays the fees on a TRC20 transfer?
TRX held in the wallet, energy and bandwidth that cover part of each transfer, or TRX burnt when those run short.
How do I track a bitcoin transaction?
Paste its transaction ID, the hash, into a bitcoin explorer to see whether it is waiting or confirmed, how many confirmations it has and the fee paid.
