Pancake Swap (referred to as pancake for short) is a decentralized exchange on the BSC network. It adopts the automatic market making business opportunity system to promote token exchange. It was launched by a group of anonymous developers in September 2020.
The segregated margin of dYdX allows users to allocate specific funds in their accounts as part of the transaction, while the cross margin makes use of all the assets that traders retain on the platform.
In the past three years, Uniswap, as a decentralized automated market making transaction protocol, has accounted for about 50% of the contract calls on Ethereum, which is enough to show its unshakable leading position.
At present, most DEX have borrowed some functions from Uniswap in some way to run their own platforms. The protocol has three versions (V1, V2 and V3).
Uniswap, the most popular DEX built on Ethereum, was launched in November 2018. It uses AMM model, liquidity pool instead of order book, and provides LP Token for liquidity provider.
