SHIWA is a project that was born to unite people around the world regardless of their origin, 
we are a great community and we will reach everyone. For this reason SHIWA presents our BIG NEWS.

SHIWA is going to launch on ETH chain!!! Also we launch with SHIWASWAP.

10/17/22 08:00 UTC

What's this means?‼️

SHIWA will be present in both chains. 🔥

How it will work as ecosystem?‼️

#SHIWA will continue its journey to create a great ecosystem and uses for the community. 
1% of the fees generated in each transaction of the ETH network will be used to buy back and burn SHIWA in 
the ETHW network.

What can SHIWA holders expect from the ETHW network?‼️

Investors who hold SHIWA will see how the team grows the price of SHIWA and how the supply is reduced, 
creating greater buying pressure that will cause shiwa's value to grow week by week in ETHW.

What about SHIWA on the ETH network?‼️

The SHIWA team will continue to work to create a great ecosystem with utility to grow and endure over time, 
attracting more investors day by day.
