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

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

Getting Started

Requirements

• git
  • You'll know you did it right if you can run git --version and you see a response like git version x.x.x
• foundry
  • You'll know you did it right if you can run forge --version and you see a response like forge 0.2.0 (816e00b 2023-03-16T00:05:26.396218Z)
• foundry-zksync
  • You'll know you did it right if you can run forge-zksync --help and you see zksync somewhere in the output

Installation

git clone https://github.com/GHexxerBrdv/EIP-4337-AA.git
cd EIP-4337-AA
forge build

Quickstart

Vanilla Foundry

foundryup
forge test

Deploy

This project of Account Abstraction will perform operatios on Token smart contract in src folder. If you have your own token deployed on anychain then just replace address of the target in /script/HelperConfig.s.sol like following.

return NetworkConfig({
    .....
@>  target: 0x6b233dd6d07177824634f839BB692373A76404eB,
    .....
});

make sure you have made .env file and save your wallet privatekey and rpc-url for test network.

source .env

Deploy token contract. Here Polygon amoy is used for all the deployment.

forge script script/Token.s.sol --rpc-url $POLY --broadcast

after deploying token on test chain grab the deployment address and update the target address in /script/HelperConfig.s.sol shown above.

Now, Let's deploy our smart contract account.run the following command

forge script script/EIP4337AA.s.sol --rpc-url $POLY --private-key $PRIV --broadcast

User operation (Interactions)

Now interact with deployed smart contract account by using /script/signedPackedUSerOperations.s.sol.

1. Fund the smart account.

forge script script/signedPackedUSerOperations.s.sol:fundAA --rpc-url $POLY --private-key $PRIV --broadcast

2. interact with smart account.

forge script script/signedPackedUSerOperations.s.sol:signedPackedUSerOperations --rpc-url $POLY --private-key $PRIV --broadcast
