What is Automated Market Maker (AMM)?

Forget order books, the future of Decentralized Exchanges lies in Automated Market Makers. Automated Market Maker AMM enables traders to earn shares of transactions in exchange for becoming liquidity providers. What does it mean for DEXs? 

In this article you will learn:

  • What are Automated Market Makers?
  • How does Automated Market Maker work?
  • AMM vs On-chain / Off-chain order book 
  • How to implement liquidity pools into your DEXs
  • Why are Automated Makers so important for the whole DeFi ecosystem?

Automated Market Makers were first introduced to the public with the release of Uniswap in 2018. 

Essentially, they are autonomous trading machines that replace traditional order books with liquidity pools run by algorithms. 

What are Automated Market Makers?

As we mentioned in one of our previous articles, a decentralized exchange can handle trading in three ways:

  • On-chain order book
  • Off-chain order book
  • Automated Market Maker AMM

The last one is undoubtedly the most efficient. That's why the vast majority of modern decentralized exchanges are based on it.

Definition:

Automated Market Maker AMM is a decentralized exchange protocol that relies on smart contracts to set the price of digital assets and provide liquidity.

Cryptocurrency assets are priced according to a pricing algorithm and mathematical formula, instead of the order book that is used by traditional exchanges.

The mathematical formula varies from protocol to protocol. Uniswap, for example, uses the following formula:

a * b = k

Where 'a' and 'b' are the number of tokens traded in the liquidity pool. Since 'k' is constant, the  total liquidity of the pool must always remain the same. Different AMMS use various formulas. However, all of them set the price algorithmically. 

What's important, Automated Market Makers allow almost anyone create a market using blockchain technology.

How Automated Market Makers work?

For trading pairs, for example, BTC/ETH, Automated Market Makers work similarly to order books, which are based on buy and sell orders. However, a vital difference is that a trading pair isn't needed to make a trade. Alternatively, users can interact with a smart contract that will constitute the other side of the trading pair for them. This is what the term “automated market-making” refers to. 

P2P and P2C

You are probably familiar with the term “peer-to-peer transactions,” which is crucial to understanding decentralized exchanges. Every transaction that runs between two users without any intermediary can be called P2P. 

We can think about Automated Market Makers as peer-to-contract solutions because trades take place between users and a smart contract. 

Liquidity pools

Trading pairs, which you know from Centralized Exchange and Decentralized Exchange using order books, are an individual liquidity pool in Automated Market Maker. Therefore, users are essentially trading funds with liquidity pools, rather than with other users. 

If you want to trade two tokens, for example, sell BNB for Ether, you need to find the BNB/ETH liquidity pool. 

We can imagine a liquidity pool as a large pile of assets. But where do they come from?

Liquidity providers 

The answer might sound quite surprising: funds are added to liquidity pools by the users of the exchange. Or, more precisely, liquidity providers.

In exchange for providing liquidity, liquidity providers earn fees on transactions in their pool. Unlike traditional market making with professional market makers, here anyone can become one. 

Profits for liquidity

To become a liquidity provider you need to deposit both assets represented in the pool. Adding funds to the liquidity pool is not difficult and rewards are worth considering. The profits of liquidity providers differ depending on the platform. For instance, on Uniswap 0,3% of every transaction goes to liquidity providers.

Slippage on Automated Market Makers

Different Automated Market Makers may encounter different issues. Yet the risk of slippage is something we should always keep in mind while planning our own DEX. 

Why does it occur?

As I mentioned earlier, asset pricing is determined by an algorithm and a mathematical formula. We can say that it's determined by the ratio between the assets in the liquidity pool. Or more specifically, it is the change in this ratio that occurs after a trade. The larger the transaction, the wider the margin of change, and the greater the amount of slippage. 

Indeed, when a large order is placed in AMMs and a sizable amount of coin is removed or added to a liquidity pool, it can even cause a notable difference between the market price and the pool price. 

More liquidity = less slippage 

In the Automated Market Maker model, more liquidity means less slippage that large orders may incur. Ultimately, this may attract more volume to your DEX. That's why if you want to use Automated Market Maker on your platform, you need to have a solid strategy for encouraging your users to deposit funds in liquidity pools.

You need to remember that to stay competitive in the decentralized finance market, you should offer liquidity of at least a sufficient level. 

Generally, exchanges decide on sharing profits generated by trading fees with liquidity providers. In some cases (e. g. Uniswap), all the fees go to liquidity providers. If a user's deposit represents 5% of the assets locked in a pool, they will receive an equivalent of 5% of that pool’s accrued trading fees. The profit will be paid out in liquidity provider tokens. When users want to leave the pool, they simply exchange their tokens for their share of transaction fees. 

Yield Farming

Yield farming is one of the most important opportunities that can attract new users to your DEX platform. How does it work? What does it even mean? 

LP tokens

We often say that liquidity has a pivotal value in the DeFi space. Creating tokens that are awarded in exchange for providing liquidity is a great idea to increase it. 

Normally when a token is staked or deposited somehow, it cannot be used or traded, which decreases liquidity in the whole system. In the case of Automated Market Makers, implementing easily convertible liquidity provider tokens solves the problem of locked liquidity. Their mechanism is simple: users get them as proof of owing tokens that they have deposited. 

With LP tokens, each token can be used multiple times, despite being invested in one of the liquidity pools. Additionally, we can say that LP tokens open up a new, indirect form of staking. This means that instead of staking tokens themselves we just prove that we own them. 

What is Yield Farming? 

Yes, on multiple exchanges users can stake their LP tokens and profit from them. Essentially, this is what we call yield farming. The main idea behind it is to maximize profits by moving tokens in and out of different DeFi protocols.

How does it work on DEXs? 

Actually, from the user perspective it's quite simple:

  • deposit assets into a liquidity pool 
  • collect LP tokens
  • deposit or stake LP tokens into a separate lending protocol
  • earn profit from both protocols 

Note: You must exchange your LP tokens to withdraw your shares from the initial liquidity pool.

What is impermanent loss?

Impermanent loss occurs when the price ratio of two assets changes after traders deposit them in the pool. The higher the shift in price, the more significant the impermanent loss. Impermanent loss mostly affects liquidity pools with highly volatile assets. 

However, this loss is impermanent: there is a probability that the price ratio will revert. Permanent losses can only occur if liquidity providers withdraw their digital assets before the price ratio reverts. 

Conclusion 

Of all the solutions that we can currently observe on decentralized exchanges, the Automated Market Maker offers the highest liquidity. Today most DEXs are running on AMM or plan to implement it in the nearest future. That's why Automated Market Maker has crucial importance for the DeFi ecosystem.Do you want to know how to apply Automated Market Maker in your project?

Token Engineering Process

Kajetan Olas

13 Apr 2024
Token Engineering Process

Token Engineering is an emerging field that addresses the systematic design and engineering of blockchain-based tokens. It applies rigorous mathematical methods from the Complex Systems Engineering discipline to tokenomics design.

In this article, we will walk through the Token Engineering Process and break it down into three key stages. Discovery Phase, Design Phase, and Deployment Phase.

Discovery Phase of Token Engineering Process

The first stage of the token engineering process is the Discovery Phase. It focuses on constructing high-level business plans, defining objectives, and identifying problems to be solved. That phase is also the time when token engineers first define key stakeholders in the project.

Defining the Problem

This may seem counterintuitive. Why would we start with the problem when designing tokenomics? Shouldn’t we start with more down-to-earth matters like token supply? The answer is No. Tokens are a medium for creating and exchanging value within a project’s ecosystem. Since crypto projects draw their value from solving problems that can’t be solved through TradFi mechanisms, their tokenomics should reflect that. 

The industry standard, developed by McKinsey & Co. and adapted to token engineering purposes by Outlier Ventures, is structuring the problem through a logic tree, following MECE.
MECE stands for Mutually Exclusive, Collectively Exhaustive. Mutually Exclusive means that problems in the tree should not overlap. Collectively Exhaustive means that the tree should cover all issues.

In practice, the “Problem” should be replaced by a whole problem statement worksheet. The same will hold for some of the boxes.
A commonly used tool for designing these kinds of diagrams is the Miro whiteboard.

Identifying Stakeholders and Value Flows in Token Engineering

This part is about identifying all relevant actors in the ecosystem and how value flows between them. To illustrate what we mean let’s consider an example of NFT marketplace. In its case, relevant actors might be sellers, buyers, NFT creators, and a marketplace owner. Possible value flow when conducting a transaction might be: buyer gets rid of his tokens, seller gets some of them, marketplace owner gets some of them as fees, and NFT creators get some of them as royalties.

Incentive Mechanisms Canvas

The last part of what we consider to be in the Discovery Phase is filling the Incentive Mechanisms Canvas. After successfully identifying value flows in the previous stage, token engineers search for frictions to desired behaviors and point out the undesired behaviors. For example, friction to activity on an NFT marketplace might be respecting royalty fees by marketplace owners since it reduces value flowing to the seller.

Design Phase of Token Engineering Process

The second stage of the Token Engineering Process is the Design Phase in which you make use of high-level descriptions from the previous step to come up with a specific design of the project. This will include everything that can be usually found in crypto whitepapers (e.g. governance mechanisms, incentive mechanisms, token supply, etc). After finishing the design, token engineers should represent the whole value flow and transactional logic on detailed visual diagrams. These diagrams will be a basis for creating mathematical models in the Deployment Phase.

Objective Function

Every crypto project has some objective. The objective can consist of many goals, such as decentralization or token price. The objective function is a mathematical function assigning weights to different factors that influence the main objective in the order of their importance. This function will be a reference for machine learning algorithms in the next steps. They will try to find quantitative parameters (e.g. network fees) that maximize the output of this function.
Modified Metcalfe’s Law can serve as an inspiration during that step. It’s a framework for valuing crypto projects, but we believe that after adjustments it can also be used in this context.

Deployment Phase of Token Engineering Process

The Deployment Phase is final, but also the most demanding step in the process. It involves the implementation of machine learning algorithms that test our assumptions and optimize quantitative parameters. Token Engineering draws from Nassim Taleb’s concept of Antifragility and extensively uses feedback loops to make a system that gains from arising shocks.

Agent-based Modelling 

In agent-based modeling, we describe a set of behaviors and goals displayed by each agent participating in the system (this is why previous steps focused so much on describing stakeholders). Each agent is controlled by an autonomous AI and continuously optimizes his strategy. He learns from his experience and can mimic the behavior of other agents if he finds it effective (Reinforced Learning). This approach allows for mimicking real users, who adapt their strategies with time. An example adaptive agent would be a cryptocurrency trader, who changes his trading strategy in response to experiencing a loss of money.

Monte Carlo Simulations

Token Engineers use the Monte Carlo method to simulate the consequences of various possible interactions while taking into account the probability of their occurrence. By running a large number of simulations it’s possible to stress-test the project in multiple scenarios and identify emergent risks.

Testnet Deployment

If possible, it's highly beneficial for projects to extend the testing phase even further by letting real users use the network. Idea is the same as in agent-based testing - continuous optimization based on provided metrics. Furthermore, in case the project considers airdropping its tokens, giving them to early users is a great strategy. Even though part of the activity will be disingenuine and airdrop-oriented, such strategy still works better than most.

Time Duration

Token engineering process may take from as little as 2 weeks to as much as 5 months. It depends on the project category (Layer 1 protocol will require more time, than a simple DApp), and security requirements. For example, a bank issuing its digital token will have a very low risk tolerance.

Required Skills for Token Engineering

Token engineering is a multidisciplinary field and requires a great amount of specialized knowledge. Key knowledge areas are:

  • Systems Engineering
  • Machine Learning
  • Market Research
  • Capital Markets
  • Current trends in Web3
  • Blockchain Engineering
  • Statistics

Summary

The token engineering process consists of 3 steps: Discovery Phase, Design Phase, and Deployment Phase. It’s utilized mostly by established blockchain projects, and financial institutions like the International Monetary Fund. Even though it’s a very resource-consuming process, we believe it’s worth it. Projects that went through scrupulous design and testing before launch are much more likely to receive VC funding and be in the 10% of crypto projects that survive the bear market. Going through that process also has a symbolic meaning - it shows that the project is long-term oriented.

EVM-Compatible vs EVM-Equivalent

EVM-Compatible

EVM compatibility means a blockchain can interact with Ethereum's ecosystem to some extent. It can interact supporting its smart contracts and tools but not replicating the entire EVM environment.

EVM-Equivalent

An EVM-equivalent blockchain, on the other hand, aims to fully replicate Ethereum's environment. It ensures complete compatibility and a smooth transition for developers and users alike.

Berachain's Position

Berachain can be considered an "EVM-equivalent-plus" blockchain. It supports all Ethereum operations, tooling, and additional functionalities that optimize for its unique Proof-of-Liquidity and abstracted use cases.
