What is native account abstraction and how does it benefit crypto users?

If you’ve been following blockchain developments, you’ve probably noticed that wallets haven’t always kept pace with the rest of the ecosystem. While blockchain has evolved in countless ways, many wallets remain stuck with outdated mechanics, like 16-word seed phrases and private keys. This makes them clunky, confusing, and unhelpful in the effort to onboard the next billion users into Web3.

Most people can’t even remember their Web2 passwords on a regular basis. Expecting them to keep their seed phrase and private keys safe for eternity is a security nightmare. And the risks are high. One wrong move, be it by bad actors or negligence, can lead to the loss of millions of dollars.

This guide will introduce you to native account abstraction (AA), a solution that makes self-custody on blockchain a much more user-friendly experience.

What is native account abstraction?

To understand native account abstraction, you first have to understand the two types of user accounts currently available on Ethereum.

1. Externally owned accounts (EOA)
2. Contract accounts (CA)

Externally owned accounts (EOAs)

EOAs are the most common type of account on Ethereum and are used by wallets like MetaMask or Coinbase Wallet. Each EOA consists of a public key (your account address) and a private key. These are required to authorize and sign transactions. Together, they form a keypair.

Every transaction made with an EOA relies on this private key for security. First, the transaction is authorized and signed by the private key. Then, the Ethereum Virtual Machine (EVM) verifies it against the EOA’s account address. The EVM’s hard-coded logic directly links the account holding your tokens to the private key that signs your transactions. In doing so, it treats them as a single, inseparable unit.

The main drawback? Losing your private key means losing your funds, or even control of your account, forever.

Contract accounts

Meanwhile, contract accounts are smart contracts deployed on the Ethereum blockchain. These accounts use account abstraction and are controlled by code, rather than private keys, to make blockchain accounts easier to use. Unlike EOAs, contract accounts can’t initiate transactions independently. Instead, their transactions are triggered by instructions from EOAs. This design introduces flexibility. Developers can define how transactions are processed, paving the way for account abstraction to simplify and enhance the user experience.

Networks that support AA can be divided into two categories: those with native support and those without. Let’s explore their differences.

• Non-native support: Ethereum, the world’s second-largest cryptocurrency network by market cap, recently added support for AA. Developers building dApps can implement AA for their projects if they choose, but EOAs remain the default account type for users.
• Native support: Starknet, for example, has native support for AA. Every user account is a smart-contract account by default, meaning features like custom security, flexible authentication methods, and account recovery are available out of the box. Users don’t need to configure anything; these benefits are baked into the network.

In the following sections, we’ll compare networks with native support to those without to highlight the benefits native support brings to crypto users.

What are the drawbacks of blockchain transactions without native account abstraction?

By default, networks without native account abstraction rely on EOAs as the standard for user accounts—essentially, the basic crypto wallets most people are familiar with. This approach has several drawbacks that native AA aims to address.

Complexity issues

As mentioned earlier, interacting with dApps on networks without native AA can often make even simple tasks feel overly complicated. Take Uniswap, Ethereum’s largest decentralized exchange (DEX). Imagine you’re excited to finally swap some of your Ether (ETH) for the latest new token that’s creating a stir. Here’s what you need to do:

• • Get your wallet in order: To swap ETH for a new token, you’ll first need to set up a wallet like MetaMask. That means creating an account, backing it up with a 12-to-24-word seed phrase, and storing that phrase somewhere safe (or risk forgetting it and losing access to your funds forever!). You’ll also need to ensure your wallet has enough ETH to cover gas fees before you can make your trade.
  • Set up the transaction: Once your MetaMask wallet is ready, the next step is connecting it to Uniswap. This likely involves copying and pasting your wallet address—always double-checking to avoid mistakes—and signing multiple prompts to authorize the connection.
  • Pay required fees: Now you’re ready to swap your ETH—almost. You’ll need to pay a gas fee, typically in ETH on Ethereum-based platforms like Uniswap. While this is relatively straightforward here, things get much trickier when dealing with cross-chain transactions, where fees might need to be paid in different tokens. If you’ve ever had to juggle multiple wallets and tokens just to cover fees, you’ll know how frustrating this can be.

Security risks

EOAs place the burden of security entirely on the user. If you lose your MetaMask seed phrase, or someone hacks your account, your precious ETH and any other tokens you hold are at risk of disappearing forever.

Limited functionality

EOAs offer limited functionality compared to smart-contract accounts. They can only perform basic actions, like sending and receiving cryptocurrency. This restricts the potential for more advanced dApp features and even functionalities within Uniswap, for example, where you might want to set limit orders or automate trades.

Altogether, these hurdles can make using platforms like Uniswap feel more complicated than necessary. But native account abstraction introduces the kind of upgrade that could make blockchain as easy to use as your favorite app.

Native account abstraction features that improve blockchain usability

In contrast, networks with native AA offer a vastly different user experience. Imagine the above scenario with Uniswap, only this time on a decentralized exchange (DEX) on Starknet, which has native AA support in the form of the following features:

• Seamless sign-up: Forget the need for downloading and configuring a separate crypto wallet. AA makes it possible using your email address or even an existing social media login (if offered). No more wrestling with seed phrases or worrying about compatibility with different wallets. Instead, it’s a familiar and straightforward process that lets you get started the way you would on a regular Web2 app—without extra steps or technical barriers.
• Frictionless swapping: Ready to trade your ETH for that hot new token? With native AA, trading tokens becomes a one-click experience. Complex processes like wallet connections, approvals, and transaction signing taking place in the background. You simply select which token you want to swap and how much of it to trade, and the DEX takes care of the rest.
• Convenient fee payment: Forget needing ETH just to cover gas fees. AA enables the use of paymasters, which are smart contracts that let you pay fees in any supported cryptocurrency.
• Enhanced security: Managing private keys is no longer your responsibility. With native AA, platforms like Starknet secure your assets directly, removing the risk of lost seed phrases or hacked wallets. It’s a layer of security that keeps your funds safe while letting you explore DeFi with confidence.
• Advanced features: Smart-contract accounts unlock new ways to interact with platforms like Uniswap. You can set up limit orders, automate recurring purchases, or integrate with other DeFi tools—all built directly into the account. It’s a level of functionality that traditional EOAs can’t match.

Key benefits and use cases of native AA

It’s important to understand that the benefits of native account abstraction go far beyond decentralized exchanges like Uniswap. Native AA has the potential to make dApps more accessible and user-friendly for everyone, not just those who are already comfortable navigating crypto.

To really see how transformative native AA can be, let’s break down the key benefits and use cases it brings to users across the network.

User experience benefits

• Improved user experience: AA simplifies user interaction with the blockchain by abstracting away the complexities of private-key management (imagine a world without private keys, yet more secure wallets!).
• Greater flexibility: Smart-contract accounts can be tailored to handle complex rules for spending or interacting with dApps. This opens the door for more advanced use cases, such as automating specific workflows or creating highly customized account functionality.
• Daily spending limits: Just like your credit card, smart-contract native AA wallets can enforce spending limits to help manage usage. For example, Braavos, a smart wallet on Starknet, recently rolled out daily spending limits as a new feature, making budgeting on blockchain easier than ever.
• Seamless subscription services: Recurring payments, such as subscriptions, can be automated with smart-contract accounts. This feature makes blockchain payments as convenient as setting up auto-pay for your favorite streaming service.

Security and authentication mechanisms

• Multi-factor authentication (MFA): Just like 2FA secures your online accounts, native AA enables multi-factor authentication for your wallet. This adds an extra layer of protection, helping keep your funds safe from unauthorized access.
• Hardware signers: Smartphones can double as secure signers for blockchain transactions. With native AA, users can verify transactions using biometric authentication like fingerprints or facial recognition through mobile wallets (pretty neat, huh?). In fact, Starknet wallet Braavos enables both of these features.
• Quantum-resistant and gas-efficient signatures: Some current signature schemes are both expensive in gas fees and vulnerable to future quantum computing threats. Native AA allows accounts to adopt more efficient and quantum-resistant signatures, reducing costs and enhancing security for users. In simple terms, you gain access to cheaper, more secure accounts!
• Recovery mechanisms: We’ve all had nightmares about losing our private keys (haven’t we?). With native AA, wallets can incorporate social recovery features, enabling users to regain access to funds through their email or designated guardians.

Alternative transaction and payment methods

• Secure multi-party payments: Smart contract accounts can be programmed to facilitate secure escrow services or multi-party payments, where funds are released only upon meeting predefined conditions.
• Paymaster access: Forget about having the right token for gas fees. Paymasters, a feature enabled by native AA, allow users to pay gas fees in any token they hold. Platforms can also cover certain transaction fees for users, creating a more flexible and user-friendly experience.

That said, networks with non-native AA can still enjoy smart-contract accounts and their benefits. However, the process is often more complex. Developers need to handle additional configurations, adding time and effort to the build, and users typically face a more cumbersome experience.

On networks like Starknet, where native AA is supported by default, these benefits are easier to deliver. Developers can build dApps that offer streamlined onboarding, flexible fee payments, and enhanced security with minimal setup. For users, this means dApps that feel intuitive and straightforward. The result? blockchain tools that are as approachable as any other app they use.

Conclusion

Making blockchain more accessible starts with simplifying how users interact with it, and native account abstraction does exactly that. To take full advantage of native AA, focus on creating tools and experiences that feel intuitive from the start. Use the flexibility of smart-contract accounts to implement features like seamless onboarding, secure recovery options, and multi-factor authentication. Collaborate with partners and platforms like Starknet did with Visa to expand adoption and showcase real-world use cases that highlight the benefits of AA. Networks like Starknet provide the foundation; now it’s up to developers and innovators to build solutions that make blockchain work for everyone.
