What Is a Cryptocurrency Wallet Address and How to Protect Against Risks
A wallet address is a unique identifier composed of letters and numbers. It serves as a destination for sending and receiving cryptocurrencies like Bitcoin, Ethereum, USDT, and others.
Key Features of Wallet Addresses
- Format: Typically a long alphanumeric sequence or a scannable QR code.
- Specificity: Each address is tied to a specific cryptocurrency and blockchain network (e.g., USDT on TRC-20 vs. ERC-20).
- Interchangeability: QR codes and text addresses represent the same destination.
Example Addresses:
- Bitcoin (BTC): Starts with "1" or "3" (e.g.,
1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa). - Ethereum (ETH): Starts with "0x" (42 characters).
- Tron (TRX): Starts with "T".
