Zephyr is a Hong Kong-based crypto money project using blockchain technology. I must say this from the beginning; users did not like this project at all and the project was closed in a short time. Listed only on the Bitshares exchange.
Zephyr is open source and open to development. Zephyr features are as follows;
1) Modular and scalability
2) Coin engineering with powerful configuration tools
3) Compatibility with hardware wallets (I couldn't run compatible with Ledger Nano S)
4) Strong infrastructure
It is made available by Bitspark as a payment token.
When you enter Zephyr's website, they wrote that this money supports hardware wallets and works compatible with hardware wallets. I have a Ledger Nano S hardware wallet and bought this cryptocurrency to try it out, but I cannot store it in my hardware wallet because I get a not compatible warning.
What I wrote above were the features that existed when this crypto currency was in use, but this coin is no longer used and has been taken out of service.
