MintDex - A true onchain DEX with no centralized server!

MintDex is a true onchain only DEX, with no centralized server needed. You can run the MintDex on your own computer, and thus eliminate the threat of DNS attack or server hack, since there is no server needed. However, to provide user easy access, a hosted version is given here for user easier access on github. You can download the source and run from your own computer, why? because even at github, hacker can still hack it. The most secure way is to run the software entirely on your own computer. MintDex is now running on Public Mint testnet.

Why Public Mint?
1) For trading to be meaningful, it must be low cost in fee. Public Mint has very low fee for calling contracts.

Gas Fee for Public Mint Testnet
Maker Gas Fee - $0.71
Taker Gas Fee - $0.37
Deposit USD Fee - $0.07
Withdraw Token Fee - $0.11

2) Confirmation speed must be fast. Traders can't wait for 5 to 30 minutes to confirm a trade. Public Mint confirmation time is only about 4seconds, a lot faster than Ethereum and make trading meaningful.

3) Fiat deposit/withdrawal. The blockchain should provide an easy way to deposit and withdraw fiat without the need to go through a centralized exchange, which is risky (many previous hacked on centralized exchanges happened before, hundred of millions of dollars lost). Public Mint provides a very easy method to deposit and withdraw fiat via its fiat native blockchain.
