Account abstraction

Account abstraction is a broad category of fast-moving development in the Ethereum ecosystem. It generally refers to different ways to create and manage accounts, other than using a Secret Recovery Phrase and a wallet.

One milestone in this area was the inclusion of ERC-4337 in the Ethereum protocol.

This includes, but is not limited to:

  • Creating accounts using a cryptographic library running in a dapp (an "embedded wallet")
  • The creation of an account that is to some degree controlled by a smart contract

That second point may seem small, but it enables things like:

  • Account Recovery ("social recovery", recovery via email or other identities or accounts)
  • Use case-specific limitations
  • Paying for a user's gas fees
  • Delegation of assets

and a lot more.

As a network, Linea is heavily invested in innovating in the account abstraction space; consult the resources here to see how you can implement the tools we already have... and then build your own.
