@maueth/aa-passkeys-wallet

An AA wallet implemented completely with PassKeys

A strawman implementation of an Ethereum wallet using PassKeys. This is a proof of concept, and is not intended to be used in production. This is based off the Infinitism Repo using Foundry for build and test. A frontend to this for contracts deployed on Mumbai - Polygon testnet and Goerli - Base testnets are available here.

Whats different on this implementation

1. A heavily modified and optimised version of the Secp256r1 signature verification solidity implementation contract which is used for verifying the signatures of the transactions.
2. Support for multiple Passkeys on an account.
3. Ability to remove a Passkey from an account.
4. A signature payload which heavily relies on the client to do as much of the prework as posible, this is to reduce the gas cost of the transactions.

Setup

1. forge install to install the dependencies
2. forge test to run the tests
3. forge build to build the project
4. forge build --skip test --skip script to build the project for release
5. npm run typechain to generate the typechain files
6. npm run build to build the front end bindings

Deploying locally

1. Bring up anvil with anvil
2. Install the Create2 proxy from here
   1. TLDR
   2. Fund the deployer 0x3fab184622dc19b6109349b94811493bf2a45362 on testnet
   3. Run curl http://localhost:8545 -X 'POST' -H 'Content-Type: application/json' --data "{\"jsonrpc\":\"2.0\", \"id\":1, \"method\": \"eth_sendRawTransaction\", \"params\": [\"0xf8a58085174876e800830186a08080b853604580600e600039806000f350fe7fffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffe03601600081602082378035828234f58015156039578182fd5b8082525050506014600cf31ba02222222222222222222222222222222222222222222222222222222222222222a02222222222222222222222222222222222222222222222222222222222222222\"]}"
3. Install the contracts forge script script/PassKeysAccount.s.sol:AnvilScript --fork-url http://localhost:8545 --broadcast uses ANVIL_PRIVATE_KEY env variable for deploying the contracts, ensure the account has enough funds to deploy the contracts.
