Best 6 DeFi Projects Reveal:

Symphony Finance

https://hackerlink.io/buidl/1221?roundProj=896

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.
