For example, I can cite EOS, which before running mainnet was an ERC-20 token based on Ethereum. This means that EOS was completely dependent on blockchain Ethereum, the transaction fee was taken in ETH, but now EOS has its own blockchain, with zero transaction fee and does not depend on Ethereum. The same should happen with the TRON token, which is now an ERC-20 token on the basis of Ethereum, but with the launch of mainnet it will become a full-value and not dependent on Ethereum coin.
