Anyone looking into "trc20 vs erc20" 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 still reveals 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 sum.
A TRC20 wallet address is an address on the TRON network, where USDT and other TRC20 tokens are received, and it usually starts with a capital T and runs to 34 characters. Addresses for BEP20 and ERC20 both start with 0x and can be exactly the same on those two chains. An address alone therefore does not reveal which network it belongs to. The network is chosen from a menu on both sides of the transfer, and USDT sent on one network does not appear on another by itself.
A bitcoin wallet address is a long run of letters and digits that usually starts with 1, 3 or bc1, depending on its type. Finding the address of a personal wallet means opening it and tapping Receive. Many wallets show a fresh bitcoin wallet address for each payment to protect privacy, and older ones keep working. The receive page also shows a square code the camera can scan, which avoids typing errors. A pasted address still deserves a second look, with characters at its start, middle and end checked against the original.
