How crypto wallet addresses work
By CardCashGo Editorial Team ·
A wallet address is like an account number for crypto. Anyone can send to it, but only the key holder can spend from it.
Public address vs private key
The address is safe to share. The private key controls the funds and must never be shared.
Supported CardCashGo addresses
Use your BTC address on Bitcoin, your ETH address on Ethereum mainnet, and your USDT-TRC20 address on TRON mainnet. TRON addresses start with T. USDT on ERC-20 or any other network is not supported.
Check the network
Each address belongs to one network. Sending on the wrong network can lose the funds permanently.
Double-check before sending
Paste addresses rather than typing them, and compare the first and last characters before you confirm.
