# Oolong finance

## Welcome to Oolong

Oolong is one of the best decentralized financial protocols on Thundercore. 

The main concept is to maximize both benefits of TT holders and USD holders. Just like oolong, the oxidation is between black tea and green tea, but the awesomeness is way much better.

### **Dual Investment**

When you invest in the financial product Dual Investment, it is like entering the "cat state". It enables your positions to have higher returns, the smart contract will snapshot the anchor price of TT and the guaranteed return, if TT price goes higher after it’s matured, you'll get the returns as USD, if the price goes lower, you'll get the return as TT.

### Supplying TT

You can provide your TT to be the seller of dual coin. The TT providers get the rest of Dual Investment's profit, and also mine some oolong tokens. When you withdraw your TT, the mining will stop and 0.1% of TT will be reserved for future profit sharing of oolong holders.
