PancakeSwap is an automated market maker (“AMM”) that allows two tokens to be exchanged on the BNB Chain. It is designed to be fast, cheap, allowing anyone to participate.
Perpetual Protocol, launched in 2019 as "Strike Protocol", is a decentralized perpetual contract protocol for every asset, made possible by a
Virtual Automated Market Maker (vAMM) design (constant product curve). Perpetual Protocol is composed of two parts: Uniswap-inspired Virtual AMMs backed by fully collateralized vaults and a built-in Staking Pool that provide a backstop for each virtual market.
Compound (COMP) is an ERC-20 asset that powers the community governance of the Compound protocol; COMP token-holders and their delegates debate, propose, and vote on changes to the protocol. By placing COMP directly into the hands of users and applications, an increasingly large ecosystem will be able to upgrade the protocol and will be incentivized to collectively steward the protocol into the future with good governance.
