“Account abstraction iscryptocurrencyof the future.”

You may have heard this phrase many times, but you don’t know exactly what it means. Today, let’s solve this problem.

I will introduce you to a beginner's guide to account abstraction -What it is, how it works, and how it will revolutionizecryptocurrencyapplication.

We will not delve into the technical and implementation details of account abstraction (that is a topic for another time). Instead, we will provide a high-level overview and show through practical examples how account abstraction has improved over the past few years.cryptocurrencyuser experience.

Simply put, account abstraction is a set of frameworks and standards that can greatly improve encryptionwallet(account) functionality.

You can think of it like giving a 1999 Honda Civic the ability to fly. It still drives as a car, but now it can do so much more.

You might ask, why encryption?walletWhy don’t we have these powerful features by default? The answer is that in some modernBlockchainIn fact, they are powerful, but for traditionalBlockchain, accounts were designed before we fully understood all of their potential uses and pitfalls.

On Ethereum (and many EVM chains), we primarily use Externally Owned Accounts (EOAs). These are simple wallets that can only hold assets and initiate transactions. They are tied to a single private key and cannot perform complex operations.

At the same time, we also have intelligentcontract,existBlockchainAutomatically execute code on thecontractCan be programmed to perform almost any task.

If we can make intelligencecontractWouldn’t it be cool to add greater flexibility to everyone’s crypto wallet? This is where Contract Accounts (CAs) come in — they are a core part of the account abstraction.

Contract accounts integrate the unlimited functionality of smart contracts into wallets, greatly enhancing their functionality. These wallets can still hold funds, but are no longer dependent on a single private key.

In the past, if you lostPrivate Key, which is equivalent to losing your wallet.

This is a very bad experience for non-cryptocurrency users. With a contract account, the wallet can operate through a variety of authentication methods without the need for traditional private key signatures.

You can use fingerprint recognition, third-party providers (such as Google, Apple), multi-signature, or different signing schemes for authentication.

Even if you do lose your original private key, you can still recover your account through a set method.

There are many ways to build account verification. These methods can not only improve the walletSafetyAccount abstraction (AA) also gives wallets new functions.

In Externally Owned Accounts (EOAs), all transactions must use on-chain native gasTokenPayments must be made by the initiator. In addition, only one transaction can be made at a time.

But with AA:

• Transactions can be fully sponsored by a third party (usually an application)

• Transactions can be made with differentTokenPayment (e.g., pay with USDC instead of ETH)

• 交易可以批量处理，节省 gas 费，并允许在不需要单独批准的情况下进行Token交换

It can be seen that AA can significantly improve the user experience of crypto applications. Before, we were bound by a rigid structure, making it cumbersome and difficult to get started with cryptocurrency. Now, with AA, we can create a user experience that is comparable to or even better than traditional Web2 applications.

It is important to emphasize that these smart contract accounts remain entirely controlled by the users themselves, and no third party can access the users’ funds - all assets remain self-custodial.

So, what is the current status of AA?

On the EVM, we have proposals such as ERC-4337 and EIP-7702 that lay the foundation for AA.

Today, many of the features I mentioned are already implemented. However, converting existing wallets to contract wallets still requires a lot of work.

In the future, I will publish a detailed account abstraction guide that goes into more detail.

For now, all you need to know is that AA is our way of implementing simple,Safetyand the key to a strong user experience that will welcome the next wave of crypto users.
