OrderSwap is a decentralized exchange built by Deland Labs based on DFINITY. OrderSwap also introduces an order book model on the basis of AMM, allowing users to set buy and sell orders according to the target price. This mode is more familiar to users and will further enhance the user experience. So in terms of transaction model, OrderSwap is a combination of 0x protocol and UniSwap.

DFINITY enables OrderSwap to achieve a speed close to that required by Internet applications, and can carry a huge user group; the reverse Gas model smoothes the threshold for users to enter the blockchain world, so that users do not need to pre-deposit tokens for using OrderSwap as Gas fee; DFINITY's encryption algorithm and blockchain design also provide sufficient security to ensure that users' assets are not lost.
