A Comprehensive Guide to ERC-4337: Understanding Account Abstraction in Ethereum

If you're involved in the world of blockchain and cryptocurrencies, you've probably heard of Ethereum, one of the most popular platforms for developing decentralized applications. Ethereum has been around for a few years now, and while it has been successful in many ways, there are still some limitations to the way it currently operates. That's where ERC-4337 comes in – a proposed Ethereum Improvement Proposal (EIP) that aims to introduce a new feature called "account abstraction" to the Ethereum blockchain. In this article, we'll take a closer look at what ERC-4337 is, how it works, and what it means for users.

Definition of ERC-4337

ERC-4337 is a proposed EIP that aims to introduce account abstraction to the Ethereum blockchain. This would allow smart contracts to directly receive and send funds without the need for an intermediary account.

Overview of Ethereum and its limitations

Before we dive into account abstraction, let's first understand Ethereum and its limitations:

  • Ethereum is a blockchain platform that enables developers to build and deploy decentralized applications, or dApps, on top of it.
  • Ethereum uses a native cryptocurrency called Ether (ETH) to incentivize miners to process transactions and secure the network.
  • Ethereum has some limitations, such as scalability, privacy, and security, that need to be addressed to make it more usable and accessible.

What is Account Abstraction?

Under the current account-based model used in Ethereum, smart contracts cannot directly receive or send funds. Instead, they rely on an intermediary account to execute transactions. Account abstraction, on the other hand, allows smart contracts to have their own unique address, enabling them to directly receive and send funds without an intermediary account. This would enable more complex smart contract interactions and make Ethereum more flexible.

What does ERC-4337 actually mean to you?

If you're looking for a more streamlined and user-friendly experience when it comes to interacting with decentralized apps (dApps) on the Ethereum network, then ERC-4337 might be just what you need. This new standard for contract accounts introduces several benefits that could make your life as a crypto user easier and more efficient.

  • Simplifying Wallet Access: You'll appreciate the simplification of wallet access and logins. With ERC-4337, you won't need to deal with cumbersome private keys or seed phrases when logging in to your wallet. Instead, you can use your Ethereum address as your login ID, making the process much more user-friendly.
  • Recovery Options: You'll have enhanced recovery options in case you lose access to your account. Unlike with traditional Ethereum accounts, ERC-4337 allows you to add recovery addresses to your contract account, giving you more flexibility and security in the event of a lost password or stolen device.
  • Sponsoring Gas Fees:You'll enjoy the option of having your gas fees sponsored, which could save you a significant amount of money in the long run. With ERC-4337, you won't need to worry about paying for gas fees yourself, as a third party can cover them for you in exchange for a small fee.

Benefits of ERC-4337

BenefitsExplanations
Improved user experienceWith account abstraction, users would no longer need to hold and manage multiple accounts for different dApps. Smart contracts would be able to handle their own transactions, simplifying the user experience and making it easier to interact with dApps.
Increased securitySmart contracts would be able to act as account addresses, reducing the risk of hacks and attacks on externally owned accounts, which are currently the only accounts that can initiate transactions in Ethereum. This would enhance the security of the network and protect users' funds.
Easier onboarding for new developersAccount abstraction would make it easier for new developers to build and deploy dApps on Ethereum, as they would no longer need to learn the intricacies of externally owned accounts and gas fees. This would encourage more developers to build on Ethereum and increase the overall growth of the ecosystem.
Interoperability with other blockchainsAccount abstraction would enable Ethereum to be more interoperable with other blockchains that support smart contracts. This would allow for cross-chain interactions and enable developers to build dApps that leverage the strengths of multiple blockchains.

Drawbacks of ERC-4337

Although ERC-4337 offers considerable advantages, adopting it comes with certain risks. First, the added flexibility of this new standard could potentially be exploited. Moreover, compatibility problems with current wallets and applications, along with the necessity for users to trust third parties for their transactions, might present significant challenges. Furthermore, implementing ERC-4337 could demand substantial infrastructure and technical expertise, possibly raising centralization concerns. Lastly, the high expenses of the Ethereum network and the requirement for contract verification may further hinder the adoption of this standard. It is vital that users and developers remain vigilant and conscious of these potential risks while considering the implementation of ERC-4337.

Conclusion

To conclude, ERC-4337 represents a suggested Ethereum Improvement Proposal that incorporates account abstraction into the Ethereum blockchain. This enables smart contracts to directly send and receive funds without requiring an intermediary account. The new feature has the potential to streamline user experience, enhance security, and facilitate the development and deployment of dApps on Ethereum for new developers.

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.
