Account Abstraction

Account Abstraction (AA) revolutionizes Web3 authentication by integrating externally owned accounts (EOAs) and smart contracts, offering a more seamless and secure way for decentralized applications (dApps) to interact with users. These AA-powered smart contract wallets have multiple benefits:

  • Ecosystem Evolution Driven by the ERC-4337 proposal, AA aims for its adoption across the Ethereum network, striving for universal account abstraction.
  • Decentralized Integrity: Maintains decentralization and censorship resistance, core principles of blockchain technology, through the application of AA.
  • Gas Fee Sponsorship: Offers the ability for users to perform gasless transactions, with fees sponsored by the dApp developers, reducing the barrier to entry for users.
  • Sophisticated Recovery and Transfer Options: Smart contract-based wallets can implement complex recovery methods and ownership transfer mechanisms, offering enhanced security and flexibility.

Understanding EOAs & Smart Contract Wallets​

EOA, or an externally-owned account is a type of Ethereum account that is controlled by a private key. EOAs can be created through Web3Auth-powered social logins, or by using external wallets such as MetaMask, Coinbase Wallet, Rainbow Wallet, etc.

On the other hand, there are contract accounts that are controlled by smart contract codes and do not have their own private key. Safe's smart wallet is a contract account that has

enhanced capabilities, such as gas sponsorship and batched transactions.

Since contract accounts do not have their own private key, they require a signer to initiate transaction flows and produce signatures. Signers are usually EOAs that authorize actions taken by the contract account via a signature.

Web3Auth's approach to Account Abstraction​

Web3Auth leverages the combination of Multi-Party Computation based social login EOAs with AA-based smart contract wallet accounts. By incorporating MPC, AA's security and functionality are significantly enhanced. MPC distributes the validation process across multiple entities, ensuring no single party can dominate transaction processes, thus bolstering security while maintaining user-friendliness. This results in:

  • Enhanced Recoverability and UX: Utilizes social login-based MPC EOAs to offer superior recoverability and a streamlined user experience, negating the need for external wallet management.
  • Simplified Access and Management: Facilitates easier account access and management through social logins and advanced recovery mechanisms, promoting broader Web3 adoption.

Using Account Abstraction with Web3Auth​

Web3Auth's AA integration is designed to be developer-friendly, offering a range of tools and resources to simplify the process. All the major Account Abstraction providers have integrated Web3Auth into their login stacks, enhancing the accessibility and security of their platforms. Web3Auth is proud to be a part of this transformative movement, working closely with leading AA providers to ensure a seamless, secure login experience. Below are highlights from a few of these collaborations:

SafeAuth Kit​

The SafeAuth Kit, designed in collaboration with Safe, offers a transformative approach to integrating smart wallets with your application, ensuring compatibility with ERC-4337 and leveraging the principles of Account Abstraction. This innovative solution utilizes Web3Auth's MPC-powered accounts as the signer for these smart wallets, facilitating a smooth onboarding and recovery process. By doing so, it not only simplifies the user experience by streamlining their interaction with the blockchain but also enhances security and user autonomy.

With extensive assets under its management, Safe promises robust Smart Account Infrastructure Safe champions open contract standards for the digital ownership of assets, data, and identity. Their modular Smart Account framework encourages developers to innovate diverse applications and wallets. The Safe{Core} AA SDK offers kits to simplify smart contract account operations, complete with guides on integration.
