# DolphinSwap
## **Why DolphinSwap?**
### More flexible market-making capital ratio
Market makers want to get a more flexible market-making proposal, and they need a more flexible market-making trading protocol. DolphinSwap can change the proportion of 50% to a fully customized proportion. For example, in the EOS-USDT pool, it is no longer limited to the corresponding token that must be injected with the 50% value ratio, but into the user-defined proportion value tokens, such as 75% EOS and 25% USDT. Of course, if the user sets the token to two, one is EOS and the other is USDT, with a ratio of 1:1, then there is no different from Uniswap-like DEX. DolphinSwap can greatly reduce impermanent losses while increasing financial flexibility.
### Customization of global liquidity and trading fees
The trading fee of each liquidity pool can be set by the liquidity provider, and the lower trading fee will attract more traders. When users trade in DolphinSwap, the contract will automatically find better prices, lower trading fees, and asset slip points throughout the pool to complete the transaction.
### **Automated portfolio management tools**
To hedge risks and obtain relatively high returns, investors often adopt portfolio strategies. Index funds are exposure to help investors continuously obtain a portfolio.
Index funds need to be managed, however, and fund managers will charge investors for managing index funds. The advantage of the DolphinSwap liquidity pool is that it can automate index funds through arbitrager participation, without hosting, decentralizing, not only paying fees but also charging fees.
DolphinSwap will provide a more complete and flexible decentralized trading scheme and build a larger DEX ecosystem.
