Account Abstraction on Ethereum: A Deep Dive into the ERC-4337 Standard

Ethereum, since its inception, has stood at the forefront of blockchain innovation, introducing concepts that have revolutionized the industry. At its core, Ethereum is not just a cryptocurrency but a platform for decentralized applications (dApps), powered by its native token, Ether. Among the numerous advancements in the Ethereum ecosystem, one concept that is gaining momentum is Account Abstraction. This concept, particularly highlighted in the ERC-4337 standard, presents a paradigm shift in how accounts are managed on the Ethereum blockchain, promising enhanced security and a more seamless user experience.

Account Abstraction, though a technical concept, has far-reaching implications for everyday users, developers, and the broader Ethereum community. It represents a move towards a more flexible and user-friendly blockchain, addressing some of the challenges and limitations of the current account model. As we delve into this topic, we will uncover the intricacies of Account Abstraction and the pivotal role of the ERC-4337 standard in reshaping the Ethereum experience.

Understanding Account Abstraction

Ethereum primarily uses two types of accounts: Externally Owned Accounts (EOAs) and Contract Accounts. EOAs are controlled by private keys and are typically used by individuals to send transactions or interact with smart contracts. In contrast, Contract Accounts are governed by their contract code and are used to deploy and run smart contracts.

The traditional Ethereum account model, centered around EOAs, has its limitations. It often leads to complex management of private keys and lacks flexibility in transaction execution. This is where Account Abstraction comes into play. It proposes a unified account model, blurring the lines between EOAs and Contract Accounts. Under Account Abstraction, user accounts would essentially function like smart contracts, enabling more complex and secure transaction rules beyond the simple private key model.

ERC-4337 Standard: An Overview

The ERC-4337 standard represents a significant milestone in Ethereum's ongoing evolution, offering a novel approach to implementing Account Abstraction without necessitating extensive changes to the core Ethereum protocol. This standard introduces a framework that enables users to experience the benefits of Account Abstraction, bringing enhanced flexibility and security to account management on the Ethereum blockchain.

The Core Concept of ERC-4337

At its heart, the ERC-4337 standard is about enabling accounts on Ethereum to behave more like smart contracts. This shift allows for more sophisticated rules around transaction execution, which traditionally could only be applied to Contract Accounts. The key innovation of ERC-4337 is the introduction of a new entity known as the 'User Operation.' These are bundles of transactions that users sign, which are then executed by a new type of account called a 'Bundler.' Bundlers are responsible for submitting these operations to the blockchain, ensuring that they conform to the user's predefined rules.

Technical Mechanisms

ERC-4337 operates through a smart contract, known as the 'EntryPoint,' which acts as a hub for User Operations. Users send their signed operations to this contract, which then delegates the execution to the appropriate smart contract wallets. This process is facilitated by relayers who, in exchange for a fee, submit these operations to the EntryPoint. The beauty of this setup is that it does not require any changes to miners' or validators' operations in the Ethereum network, making it a less intrusive yet effective solution for Account Abstraction.

Benefits of ERC-4337

The introduction of the ERC-4337 standard brings several key advantages:

Enhanced Security: By allowing accounts to set more complex rules for transaction execution, ERC-4337 provides an additional layer of security. This includes capabilities like multi-signature verification and automated checks before transaction execution.

Improved User Experience: With ERC-4337, users can enjoy a more streamlined and flexible transaction process. For instance, they can execute batch transactions, set up recurring payments, or integrate more sophisticated wallet recovery options.

Greater Flexibility: Developers can create more innovative dApps with complex transaction requirements, thanks to the flexibility offered by ERC-4337. This could lead to new use cases and applications on the Ethereum blockchain.

Implementing Account Abstraction with ERC-4337

The implementation of Account Abstraction using the ERC-4337 standard marks a pivotal moment in Ethereum's development. This process involves several critical steps and considerations for both developers and users.

Implementation

  1. Smart Contract Wallet Deployment: The first step involves deploying a smart contract wallet compatible with the ERC-4337 standard. This wallet will manage the user's assets and execute transactions based on predefined rules.
  2. Setting Up User Operations: Users need to define their transaction rules and parameters within these smart contract wallets, known as User Operations.
  3. Utilizing Relayers and Bundlers: To execute transactions, users interact with relayers who submit their operations to the EntryPoint contract. Bundlers then include these operations in the blockchain.

Considerations for Developers and Users

  • Security: While ERC-4337 enhances security, developers must ensure that the smart contract wallets and User Operations are robust against potential vulnerabilities.
  • User Experience: Developers should focus on creating intuitive interfaces for setting up and managing User Operations, making the process user-friendly.
  • Cost Implications: Implementing ERC-4337 may involve additional costs, such as fees for relayers. Users and developers need to consider these financial implications.

Impact on the Ethereum Ecosystem

Increased Security and Trust: With more robust account security features, Ethereum can attract a broader audience, including those previously wary of blockchain's security aspects.

Enhanced User Accessibility: Simplified transaction processes and user-friendly interfaces will lower the barrier to entry, potentially leading to increased adoption of Ethereum-based applications.

Innovation in dApps Development: Developers will have more freedom to experiment with complex transaction mechanisms, leading to innovative dApps that could redefine the blockchain landscape.

Long-Term Implications

Standardization and Interoperability: Account Abstraction could become a standard feature in future blockchain platforms, enhancing interoperability across different networks.

Influence on Other Blockchains: Ethereum's move towards Account Abstraction may inspire similar developments in other blockchain ecosystems, fostering a new wave of blockchain innovation.

Conclusion

The introduction of Account Abstraction, particularly through the ERC-4337 standard, is a landmark development in Ethereum's history. It represents a significant stride towards a more flexible, secure, and user-friendly blockchain platform. As we venture into this new era, the potential of Ethereum to revolutionize not just finance but various sectors of the economy becomes increasingly evident. The ERC-4337 standard is not just an enhancement of Ethereum's technical capabilities but a step towards realizing the broader vision of blockchain technology - a more open, secure, and accessible digital future for all.

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.
