Solana is thriving not because it's any different than Ethereum but because the projects it has. Be it pump.fun making most of the cashflow with the meme coins or the Jupiter exchange making its way in and out of multi chain DEX. And projects is what powers the solana and building it's legacy one project at a time. 

Jupiter exchange one of the known pillars of the Solana is one that has been giving collaterals, disel pools and variety of the onchain asset the backing it deserves. And they are adding the stablecoin to power the Solana even more for the DEX. 

It can be traded through app in the mobile, web format. And also used inside the pairs and also for the liquidity and staking purpose too. This would keep the ecosystem closed and also no need to rely on the externals like tether and circle for the stablecoin. 

So they decided to work with the Ethena and decided to build something around that ecosystem. Current collateral for that is the USDtb and it seems like they are off to a good start with the Ethena taking the lead for the token. And they are making use of their ecosystem for building stablecoin market in Solana. 

Solana and Jupiter with such stablecoin would build the asset more stronger and also this would make the integration lot easier and better for other products who build around them. So any tokenization formed around them for business would grow over the years.
