So SIMBA wants to want to bring the best of bitcoin, its secureness and immutability and combine it with ERC-20 tokens transparency. It would be relevant especially in order to speed up the transaction speed a bit.
but in any case, transactions are now quite expensive and slow .
this issue can be resolved with the launch of ETH 2.0
as I understand it will be quite soon ! But in any case it will be a unique concept and nothing like this I have not seen on the market before and I think the project will be in demand
