# Smart contract wallet User Exeperience

Any approach to make user experience using smart contract better than before.
Also, as a developer it is quite hard to develop with confidence when it comes to 4337 validation rules.

1.5 ETH (split among maximum top 3 projects)

Requirements:

- Code needs to be viewable on GitHub
- should have working demo(script/video is acceptable)
- Need to cover any types of smart contract wallet(does not need to be 4337 related)

Criteria:

- Utility
- Innovative
- Bonus points on ERC4337 related projects
- Bonus points if you tested with known bundlers or sdk providers

**Ideas to consider:**

- Alternative cryptography to enable secure enclave based cryptography
- Metamask snap based erc4337 wallet
- Paymaster that can spend L1's gas to execute L2's userOp(or vice versa)
- MEV protected wallet
- Intent based 4337 wallet that can parse native language
- Security module for eip6900 compatible wallets
- foundry/hardhat plugin for erc4337 rule verification(static/dynamic)
- CLI for setting a test environment for erc4337
