There are many blockchains in the cryptocurrency industry: Bitcoin, Ethereum, Cosmos, Avalanche, etc. Blockchains are deprived of the opportunity to "understand each other": everyone acts according to their own rules and speaks their own language. Each blockchain has its own Native token - a coin that is used to pay for the commission:
for the Bitcoin network, this is bitcoin (BTC)
for Ethereum - ETH
For Cosmos - Atom
For Avalanche - Avax
If you want to carry out any actions, for example, send a USDT tokens to the EThereum network to another wallet, the commission will have to be paid in ETH tokens if Avalanche is an AVAX commission, etc. However, if you decide to send your USDT from Ethereum to Avalanche, your USDT will be lost. Why? Because USDT on the Ethereum and USDT network on Avalanche is not the same thing, because we remember that each blockchain lives according to its own rules.
And what to do if you urgently need to send your USDT from one network to another? For these purposes, cross -miners were invented - special applications that allow you to translate tokens from “one language to another”, that is, from one blockchain to another. In one network, the token is blocked, and in another - a copy is created that does not lose its original value. For example, if you transfer BTC from the Bitcoin network to Ethereum, it will become WBTC, i.e. wrapped.
