ERC-4337: What Does it Mean For The User?

Firstly, it's important to clarify that although EIP-4337 and ERC-4337 are often used interchangeably, they are actually distinct concepts. The process for introducing technical changes to the Ethereum ecosystem involves first submitting an Ethereum Improvement Proposal (EIP), which is then considered and approved through on-chain governance. Once this process is complete, the proposal becomes an Ethereum Request for Comment (ERC).

The transformation began with EIP-4337 and has evolved into ERC-4337. Furthermore, ERC is a constituent of the wider EIP realm, focusing primarily on protocol and development criteria.

What is ERC-4337?

ERC-4337 is an Ethereum specification, which, while not exclusively dedicated to tokenization, is designed to enhance user accounts by enabling them to function as smart accounts. A more precise definition would describe it as a method of account abstraction.

Account abstraction, made possible by the Ethereum upgrade known as ERC-4337 or Ethereum Request for Comment 4337, enables Ethereum wallets to function as smart contracts.

This means that each cryptocurrency wallet can have its own unique authorization logic to suit the requirements of different users or programs. Vitalik Buterin, a co-founder of Ethereum, and others proposed this upgrade in September 2021, and it was unveiled at ETHDenver on March 1, 2023.

Previously, the act of creating and using a wallet posed a challenge for many individuals venturing into Web3, as it was often a complicated, unclear, and daunting process. From safeguarding seed phrases to executing tentative transactions, and bland security features, all contributed to significant impediments for novices in this realm. However, with the advent of ERC-4337, wallet creation and utilization are now more straightforward and user-friendly. Consequently, it has become more accessible for individuals new to this ecosystem.

What Does it Mean For The User?

1. Smart accounts can anticipate the arrival of ERC-4337, which aims to introduce "Group-Access" wallets. This innovative feature enables lost seed phrases to be recovered through dedicated guardian contracts or accounts. By eliminating private key dependencies and enabling key abstraction, ERC-4337 transcends the traditional belief of "not your keys, not your crypto." As a result, post-ERC-4337 wallet creation eliminates the need to write down seed phrases to recover accounts, creating a more seamless user experience.
2. Whenever dealing with EOAs, signing off for each transaction is mandatory, and it can be a time-consuming process. However, incorporating account abstraction into the mix facilitates bundling transactions and submitting them in a single action, ultimately saving valuable time and reducing gas fees.
3. Consider a scenario where you need to mint several NFTs or engage in a gaming activity that necessitates utilizing your tokens (like SLP) over various sessions. In such cases, having smart contract wallets assists in pre-approving transactions based on pre-determined wallet code and session keys, making the process much more seamless.
4. Envision that you're either minting a new asset or initiating a demonstration transaction on your company's behalf. Alternatively, let's say you want to establish a DApp that allows users to transact gas-free for a certain duration (e.g., 30 days). Thanks to Paymasters integrated within smart contract wallets, this is entirely feasible. You can effortlessly execute sponsored transactions where the gas fee is removed from a separate address following confirmation.
5. In case you're covering the gas fees using your smart contract wallet, the account abstraction attribute makes it possible to use any ERC-20 token as payment. Moreover, third-party services leveraging ERC-4337 to create bespoke onboarding solutions can facilitate payment of gas fees via fiat, thanks to a smart contract upgrade.
6. As for DeFi, your smart account can be directed to allocate idle funds towards liquidity pools, generating a yield. Suppose you aim to trade tokens or NFTs instead; in that case, programming your smart account wallet to monitor specific marketplaces and exchanges for cost-effective options is necessary. Furthermore, creating token tracking metrics and directing investment flow is also doable within the smart contract capabilities.

Closing Thought

It's hard to overstate the significance of ERC-4337, and it's no wonder that even the Shanghai update, which includes token unlocking, has been postponed until April. Although account abstraction has been contemplated before, the verified OpenZepplin version of the facilitator smart contract, also known as the Entry Point, makes ERC-4337 a high-quality implementation for the entire ecosystem. However, some speculate that the timing of the implementation may be an effort to preempt a possible unstaking controversy.

To put it plainly, with the implementation of ERC-4337, even users without advanced technical skills can effortlessly begin trading NFTs, sign up for crypto newsletter memberships, engage in exciting web3 games, and establish new smart account wallets. As a result, the crypto landscape is becoming far more user-friendly and accessible for beginners.
