Let’s talk about public blockchains and the blockchain trilemma.
Different public blockchains choose different consensus mechanisms and design trade-offs, so their block times, confirmation speeds, and transaction fees vary.
To be honest, I only learned this later: when transferring between different public blockchains, make sure you’ve selected the right network. The same token often has a separate contract on each chain.
$ETH is the native currency of Ethereum, a Layer 1 public blockchain, and is used to pay for gas and staking.
It’s best to only put in money you can afford to lose.
