Best 6 DeFi Projects Reveal:

Symphony Finance

At symphony finance, we’ve implemented interest-generating limit orders. The deposited sell (input) asset, generates interest till the time order remains unfilled. With this protocol, we are trying to solve the problem of profit maximization. It’s composable with the most interest-generating protocols like Aave, Mstable, Compound, etc. Orders are automatically filled with DEXes like Quickswap, Balancer, Sushiswap, etc. One can also fill the order with his own liquidity.

My Trade

MyTrade has developed a unique algorithm that precisely integrates liquidity from both order book and AMM pool. This ‘Integrated Liquidity’ will always provide Takers with the best execution price by automatically matching orders from either the order book or the AMM pool. MyTrade V2 also introduces a unique Limit Order Mining feature which will significantly increase professional Market Maker’s capital efficiency. On top of all of this, MyTrade seeks to bring the professional trading user experience of a centralized exchange to DEX users.

However, if that timer gets to zero, the last user to make the deposit wins the grand prize. Until then, every user in the pot shares a percentage of each deposit made between them. This encourages users to build up a decent-sized balance in the pot to gain better rewards in the long term.
