Augur is a trustless, decentralized platform for prediction markets. Augur is an Ethereum-based decentralized prediction market that leverages the wisdom of the crowds to create a search engine for the future that runs on its own token, REP. Augur allows users to create their markets for specific questions they may have and to profit from the trading buys while allowing users to buy positive or negative shares regarding the outcome of a future event.

Balancer is a multi-token automated market maker (AMM) that functions as a self-balancing weighted portfolio protocol. Balancer is built on the Ethereum network. It allows anyone to create or add liquidity to customizable pools and earn trading fees. Compared to a typical constant product AMM model, Balancer uses a generalization formula that could be adjusted to any number of tokens at any amount of weightage.

Bancor is a decentralized exchange. It is distinguished from other DEX protocols by its automated market maker, which lets people deposit liquidity in a single-sided fashion, whereas many other platforms require its visitors to provide liquidity with their tokens in an inherently two-sided way. Bancor's automated market maker mechanism achieves this through its native token, BNT, which is dynamically minted and co-invested by the protocol when visitors deposit their collateral as liquidity. Besides having BNT as the unitary counterpart asset of exchange for trading on the platform, the protocol also offers a unique solution against Impermanent Loss to its liquidity providers.

Coinbase is the most trusted cryptocurrency platform, and an ideal starting point if you're new to crypto. They started in 2012 with the idea that anyone, anywhere, should be able to easily and securely send and receive Bitcoin. Today, they offer a trusted and easy-to-use platform for accessing the broader cryptoeconomy.

[When you deposit on a centralised exchange you receive an IOU for your tokens, which shows up as your wallet balance. When your tokens are held on a centralised exchange, you don't physically own them – the exchange does, and you may lose them]

Compound is a decentralized autonomous interest rate protocol. It allows people to lend and borrow their cryptocurrencies, and establishes money markets by algorithmically setting interest rates based on supply and demand of various assets. Its native token is COMP, allowing holders to propose and vote on changes made to the protocol.

Compound

The Graph is an indexing protocol for querying networks like Ethereum and IPFS. Anyone can build and publish open APIs, called subgraphs, making data easily accessible.

UMA, or Universal Market Access, is a decentralized financial contracts platform built on Ethereum. It enables users to create custom synthetic assets, which are blockchain-based contracts that can track the price of virtually anything. UMA focuses on allowing parties to write self-enforcing smart contracts with economic guarantees, using its unique "priceless" contract design that minimizes the need for on-chain price feeds. It aims to democratize and decentralize the financial derivatives market, making it accessible to anyone, anywhere, without the need for traditional financial intermediaries.

Uniswap is a decentralized exchange protocol (DEX). It allows people to set up or contribute to liquidity pools consisting of various ERC-20 token pairs, or to use the available liquidity to swap their tokens against another using its Automated Market Maker (AMM) mechanism. 


### Why

AMMS are one of the building blocks in the crypto space as they always provide users with a price between two assets. Uniswap uses a simple  X * Y = K, formula to price assets where x is the amount of one token in the liquidity pool, and y is the amount of the other. k is a fixed constant, meaning the pool’s total liquidity is always the same. 


### Risk

There are various risks involved with using AMMS. These include but are not limited to:
Protocol Risk - risk due to mechanics in the design of a protocol. Even when the protocol functions as intended there might be risks e.g. high slippage incurred in trades due to the liquidity curve set-up
Smart contract risk - This is risk from an error in the code causing the contract to operate in ways unexpected by the developers. It might leave the code vulnerable to exploits or other attacks
Cybersecurity risk - Hackers, Exploiters or other malicious actors trying to attack Uniswap 


### Reward

Uniswap is arguably one of the largest AMMs in crypto and is usually the protocol where tokens find the most liquidity. Its UI/UX is extremely simple and users can trade most tokens with little problems.

Saddle is a decentralized automated market maker on the Ethereum blockchain, optimized for pegged value crypto assets such as stablecoins and wrapped BTC.

Saddle enables cheap, efficient, swift, and low-slippage swaps for traders and high-yield pools for LPs.

Saddle’s open-sourced StableSwap implementation in Solidity is the pillar for many DeFi projects, across different verticals and blockchains.

Saddle

Futureswap is a decentralized non-custodial perpetual protocol where users can gain leveraged exposure (up to 256x) to assets. Liquidity providers deposit passive liquidity in order to earn passive income from trading fees and FST incentives. This liquidity is utilized by the Futureswap AMM and other AMMs under the hood to create leveraged exposure. Realistically under the hood, Futureswap operates as a lending protocol as no leverage contracts are being created but only liquidity providers lending funds while holding collateral.

Futureswap

Fixed rate borrowing & lending protocol with $650M+ in total lending volume.

The Forta Network monitors on-chain activity in real-time, detecting threats, security-related events and other noteworthy activity. The network is made up of thousands of detection bots developed by a community of Web3 developers and security experts. Each bot acts like a little security camera monitoring something specific on-chain. Some bots monitor generic threats (i.e. phishing attacks, rug pulls), and others monitor protocol-specific activity (i.e. Lido, Compound).


There are two primary actors in the Forta Network:

**Users, **who consume threat intel generated by the network. Users could be Web3 wallets, DeFi protocols, or centralized exchanges looking for the latest threat intel to protect their customers.

**Developers,** who create and maintain detection bots. They could be a leading Web3 security team, an independent security researcher or a DeFi core dev using Forta to monitor their protocol.
