ERC-4337 is an Ethereum standard that enables account abstraction without requiring any modifications to the protocol's consensus layer. Users will be able to conduct transactions and establish contracts using a single contract account thanks to ERC-4337, which will be made available on the Ethereum mainnet in March 2023. It paves the way for more user-friendly crypto wallet designs, which might lead to more adoption.
The Ethereum Improvement Proposals (EIPs) specify standards for the Ethereum platform, such as core protocol specifications and contract standards. ERCs, a special type of EIP, describe application-level standards, including contracts and tokens. Only if the on-chain governance approves the amendment can an EIP become an ERC.
ERC-4337 is the most recent ERC standard to be implemented on the Ethereum mainnet to realize the long-awaited objective of account abstraction. Some people still refer to ERC-4337 by its original name, EIP-4337. EIP-4337, on the other hand, was suggested in 2021 and has been approved to become ERC-4337 in 2023.
In 2021, Ethereum co-founder Vitalik Buterin and other developers suggested ERC-4337 provide account abstraction. The Ethereum mainnet release was made in March 2023, and it aims to make cryptocurrency wallets more user-friendly.
Externally owned accounts (EOA) and smart contract accounts are the two types of accounts currently supported by the Ethereum protocol. Account abstraction tries to unify their functionalities. The result is a single contract account that can both transact with tokens and create contracts. This modification allows for innovative wallet ideas such as social recovery, customization, and upgradeability.
ERC-4337 can also be viewed as bringing smart contract capability to wallets in a single account. This makes it easy to set up services like multi-factor authentication and automated payments.
To understand why ERC-4337 is required, first understand why it was suggested and enacted in the first place. Ethereum uses an account-based architecture rather than the Unspent Transaction Output (UTXO) module of the Bitcoin network. As a result, once transactions are validated, the Ethereum protocol maintains track of and changes the available balances of accounts.
The two sorts of accounts in Ethereum each have their own set of features. Users own and operate EOAs, whereas smart contract accounts are smart contracts that are distributed on the network. Both accounts may receive, retain, and transmit ether or tokens.c
Most existing Ethereum crypto wallets, such as MetaMask, are EOAs, which means they are bound by the regulations that govern EOAs. These restrictions include requiring all transactions to be signed and relying entirely on private keys to access accounts. As a result, wallet setup procedures and private key security mechanisms are frequently complicated to use. When users forget their seed phrase, they typically lose access to their wallets.
ERC-4337 eliminates such constraints. UniPass and Safe are smart contract wallets that are handled by smart contract accounts rather than EOAs and may achieve the same objective. However, customers must manage their ether in two accounts to pay gas or rely on a centralized relay mechanism. ERC-4337 eliminates such constraints by combining the functionality of the two accounts into one, making it easier to implement the required wallet features.
Account abstraction is a goal that the Ethereum community has been pursuing a while. Before EIP-4337, the community proposed EIP-2938 to achieve account abstraction. EIP-2938 was comparable to ERC-4337, however, it advocated for consensus-layer improvements. ERC-4337 works around this.
It accomplishes this by adding a higher-layer pseudo-transaction object called a UserOperation, which is related to rollups in that both use various versions of the idea of bundling. In ERC-4337, distinct users transmit UserOperation objects to a separate mempool.
Bundlers bundle these items into a transaction that is added to a block. In addition to receiving fees from each UserOperation execution, bundlers are charged gas for the bundled transactions. Bundlers operate similarly to validators, selecting which items to include based on fee-prioritization logic.
Furthermore, smart contracts can also be tethered to wallets with a new feature called validateUserOp.Furthermore, smart contracts can also be tethered to wallets with a new feature called validateUserOp. A new contract called the EntryPoint is also being developed to serve as a security gate for the execution of these new operations.
ERC-4337 eliminates these major issues that were faced by most of the common wallet structures:
1. Retrieves private keys:
One of the terrifying aspects of Web3 is that users can forget the key easily with their crypto bit which tends to lose the data in their wallet. In this case, users can retrieve their wallet access by using the “social recovery system” that is enabled while developing the ERC-4337. This upgraded version is provided for various recovery options including normal Google or Bank account. Using reinvented cryptographic key storage, your smartphone becomes a hardware wallet for cryptocurrencies.
2. Less reliance on seed phrases:
ERC-4337 seed phrases, account management code, and other developer-specific features are kept aside, resulting in an easy-to-use user interface. The ER-4337 protocol is expected to add “Group Access” wallets for smart contracts. This means if the user loses their seed phrase, they may contact the guardian contacts or accounts they previously selected for assistance in regaining their access.
Users may now secure and use their wallets with 2FA (two-factor authentication) and biometrics. Some Web3 users are there to protect themselves from the types of institutional intrusion that security technologies such as biometrics entails.
Additionally, those users and others may be reluctant to give up seed phrases since they provide an added degree of security. Also, key abstraction would eliminate reliance on private keys. If someone attempts to establish a wallet after the ERC-4337 to retrieve the account, the seed phrase will not even be required.
3. Gas-free transactions
The ERC-4337 standard offers gasless transactions, which allows for transaction bundling to speed up and enhance efficiency. This technology allows NFT collections and linked DAOs to sponsor users' petrol expenses, cutting transaction costs.
This capability also allows you to pay transaction fees with the tokens connected with an application, which reduces transaction costs. Whole blockchains, such as Avalanche and its subnets, have been constructed to make this a major feature.
4. DeFi automation and trading access
One of the most difficult parts is the amount of involvement necessary to acquire and trade NFTs. Analysis of floor pricing, scheduling mints, and tracking metrics all need near-constant work.
ERC-4337, on the other hand, allows AI trading, modifying yield farming positions, and automatic trading with a monthly expenditure restriction. These features may make trading NFTs easier and more accessible to users of all skill levels.
5. Bundled Transactions
Every EOA transaction needs signatures. It might also be tiresome. Using account reflection, it is possible to combine package exchanges and ship them as one to save time and petrol money.
ERC-4337 might put an end to the difficult crypto wallet user experience while simultaneously increasing usage. These are a few examples of what ERC-4337 may enable:
