What is Account Abstraction?

EoAs are now smart contracts. That's all account abstraction is.

But what does that mean?

Right now, every single transaction in web3 stems from a single private key.

account abstraction means that not only the execution of a transaction can be arbitrarily complex computation logic as specified by the EVM, but also the authorization logic.

• Vitalik Buterin
• EntryPoint Contract v0.6
• EntryPoint Contract v0.7

What's this repo show?

1. A minimal EVM "Smart Wallet" using alt-mempool AA
   1. We even send a transactoin to the EntryPoint.sol
2. A minimal zkSync "Smart Wallet" using native AA
   1. zkSync uses native AA, which is slightly different than ERC-4337
   2. We do send our zkSync transaction to the alt-mempool

What does this repo not show?

1. Sending your userop to the alt-mempool
   1. You can learn how to do this via the alchemy docs
