The high gas issue is that currently, the majority of DEXs use the Ethereum network. It is the auction mechanism and confirmation time that make people want faster transactions.
Currently, Justswap is a DEX based on the TRON platform and has a lower transaction cost. It resembles a copy of UNISWAP and is supported by TRON.
I believe there will be a lot of new blockchains that generate DEX and a much lower cost. Of course, those DEXs will appear in the future.
Then it's answered it already why it's only use low cost and fast transaction because this is only supporting tron blockchain .
Did I understand it right or they are also supporting any ERC20 tokens ? if they support ERC20 then how they actually can make them low cost if the eth blockchain is congested is its means the transaction need more time before it's confirm by the network?
I firmly believe TRON cannot trade ERC 20 on their DEX as they don't have wrap functionality. I find TRON's DEX just a fake and cheap thing because people don't care much about TRON projects.
ERC20 has a lot more people to trust and it's popular. TRON is just trying to make a second marketplace and entice users, I don't believe they'll succeed.
