Why is a trust line necessary for transactions with tokens and currency?

By establishing trust lines with different assets, users can participate in trustless trading and make atomic swaps between assets directly on the XRPL without relying on a centralized intermediary.

Without trust lines, accounts could be subject to receiving assets or tokens that they do not want to receive.

We use trust line as a means of consenting to receive currency or a token.

What is the difference between the testnet and livenet/mainnet servers?

When coding on the XRPL, you can test your code with the testnet before launching an app on the livenet.

The testnet uses fake XRP and fake currency. The livenet uses real XRP and currency.

New accounts on the testnet are funded via a centralized faucet, whereas the livenet requires a transfer from an exchange.
