Cryptocurrency networks
Cryptocurrency transfers are broadcasted and validated via networks of computers called blockchain networks or cryptocurrency networks.
A crypto token can be supported on multiple networks. And one network can support multiple cryptocurrencies. For example, USDT can be transferred on not only the Ethereum network, but also on Tron. Similarly, the Ethereum network supports different tokens such as ETH, USDC and USDC, among many others.
Different networks have different network fees and different times of execution. It's very important to make sure that the selected network is the same as the network of the platform you're depositing or withdrawing funds to. If you select the wrong network, it may not be possible to recover the funds.
